Chorionic gonadotropin where it is contained. HCG: level and norm, deviations - increased and decreased, in women and men. Folk remedies to stimulate ovulation

It is produced by the tissues of the chorion - the fetal membrane immediately after the fertilized egg descends into the uterine cavity and is fixed there. A special drug with the same name is also a chance to experience the joy of motherhood for those who have problems with conception. How the tool is used and what results it gives, we will tell you in this article.

What is it - a drug and analogues

"Chorionic gonadotropin" is a medicine that is obtained from the urine of pregnant women. The hormone enters the secreted fluid from the blood, which in turn is enriched with this substance during pregnancy. The hormonal substance is excreted almost unchanged, which is why it is so easily extracted from the urine of expectant mothers.

In our country, the medicine can be purchased locally, Russian production and its imported counterparts - "Pregnil", "Profazi", "Khoragon". All drugs containing hCG are prescribed by a doctor according to individual indications, unauthorized treatment with them is strictly prohibited, since it can lead to a strong hormonal imbalance in the human body.

As the name suggests, the main active ingredient of the drug is human chorionic gonadotropin. In the body of the expectant mother, it is entrusted with the most important functions - to stimulate the corpus luteum, which is formed after ovulation, to help the production of large amounts of progesterone and estrogen, to preserve the embryo and create the most comfortable conditions for it.

Partially gonadotropic hormone suppresses the aggression of maternal immunity. Without it immune defense women would simply reject a fetus that has 50% of the foreign chains inherited from the father in its DNA.

The strong action of the base substance is used in a wide variety of medical purposes... The drug in injections is prescribed for women, men and adolescents. However, the drug is most often used in gynecology and obstetrics.

Action

Chorionic gonadotropin is directly involved in the synthesis of sex hormones in both men and women. This substance significantly improves the process of production of substances in the testicles of the stronger sex and in the ovaries - in women. It affects the key "event" of the female cycle - it is this hormonal drug that is used to stimulate ovulation, if for some reason it does not occur in a woman on its own, anovulatory cycles take place.

After ovulation has occurred, the drug helps to maintain the functions of the corpus luteum - a follicle that produces hormones important for the onset of pregnancy - progesterone and estrogens. Under the influence of gonadotropic hormone, the genitals of both men and women develop correctly, and secondary sexual characteristics are formed normally.

Due to its wide spectrum of action, the drug is highly valued by reproductive specialists and obstetricians. It allows you not only to get pregnant, but also to support a "problem" pregnancy, which without hormone therapy is likely to end in miscarriage or premature birth.

Who is the drug prescribed to?

HCG injections are recommended for all women and men who visit a doctor with gutters to reduce sexual function. This includes a weak sex drive, and the inability to get pregnant on their own, and problems with reproductive functions in men.

The drug is indicated for people suffering from underdevelopment of the genitals, insufficient reproductive capabilities, dwarfism, dysfunction of the pituitary gland and hypothalamus, due to which the hormonal background is disturbed. The tool is widely used in adolescence if there is a delay in puberty.

In gynecological practice, the drug is prescribed:

women with dysmenorrhea ( severe pain during menstruation, additional unpleasant symptoms of "critical" days - nausea, vomiting, headaches, dizziness, loss of consciousness);

women with ovarian dysfunction;

women with infertility associated with the lack of ovulation in the cycle;

women who cannot get pregnant due to insufficiency of the corpus luteum;

for patients to stimulate ovulation before embryo transfer using IVF, as well as after embryo transfer to maintain pregnancy;

patients who have already had several miscarriages, especially in the early stages ( recurrent miscarriage);

pregnant women with pronounced signs of threatened termination.

Indications for the use of the drug are also hereditary problems with reproductive function in women and men.

To whom is the medicine contraindicated?

In some cases, the use of the drug will have to be abandoned, because it has a fairly large list of contraindications. So, "Chorionic Gonadotropin" cannot be used for:

hypersensitivity to this hormone, which can become the beginning of a severe allergic reaction;

with ovarian carcinoma - a cancer of the reproductive gland in women;

with neoplasms and tumors in the pituitary gland;

with the so-called hormonal tumors in the body, which are able to respond with rapid growth to the introduction of androgens;

at insufficient work thyroid gland;

with dysfunction or insufficiency of the adrenal glands;

at elevated level the hormone prolactin in the patient's blood;

with the onset of menopause, menopause;

with obstruction of the fallopian tubes, with a strong adhesive process in them;

during breastfeeding;

with diagnosed thrombophlebitis.

WITH increased measures precautions the drug is prescribed for women with ischemic disease heart, high blood pressure, renal failure, both acute and chronic, suffering from bronchial asthma.

Side effects

Like any hormonal drug, Chorionic Gonadotropin is capable of causing an allergic reaction. Usually it is local in nature, redness, slight swelling and mild itching are observed only at the injection site. Much more often the drug causes headaches. Many women complain that they feel "overwhelmed", constantly tired, some even get depressed.

If the drug is used in combination with other agents as part of complex therapy for reproductive techniques, for example, with "Clomiphene", ovarian hyperstimulation syndrome may develop, when cysts form in the ovaries, which are dangerous from the point of view of the possibility of their sudden rupture. In this case, the appearance of fluid in the abdominal cavity and chest cavity is not excluded.

Sometimes women complain of swelling, mood swings, and uncontrollable bouts of aggression. All this is the result of the effect of the hormone on the brain. It is not necessary that every patient will experience these symptoms of side effects from taking the drug, but be aware of possible consequences everyone should.

Instructions for use - dosage

The drug is available in the form of a powder, from which a solution for injection can be prepared. The box also contains an isotonic sodium chloride solution for this. Therefore, the preparation of a ready-to-use tool of labor will not be. The drug is administered exclusively intramuscularly.

The dosage depends on what is the purpose of using the drug. Women who are going for IVF or to stimulate ovulation are injected with 5000-10,000 IU of the drug once. If the treatment is carried out with the use of other means, it is important that at least a day has passed from the last intake of menotropins, and at least five days from the last intake of Clomiphene.

If the patient has insufficient functioning of the corpus luteum, then the optimal dosage for her is 1500 IU. The injection is given every two days until the moment when menstruation either begins or the test confirms the long-awaited pregnancy. The first injection is given on the day of ovulation.

The solution for injection is prepared immediately before the procedure; you should not do this in advance. The dosage of the active substance in the packages offered on the pharmacists' shelves is 500 units, 1000 units, 1500 units, 5000 units. Most suitable shape the doctor will tell you, since the treatment must necessarily take place under the supervision of an experienced specialist.

Application to stimulate ovulation

Ovulation is the release of a mature and finished egg from a mature follicle. It usually occurs in the middle of the cycle. For various reasons, the egg may be weakened, against the background of a lack of female hormones, it may not make a timely release or not mature. This is why fertility treatments often start with the promotion of healthy and normal ovulation.

This method allows you to achieve success in about 70-75% of cases, if everything is done correctly and there are no contraindications for the use of "Chorionic Gonadotropin". An important condition- the integrity of the egg. It must not be damaged. For this stimulation is preceded by thorough examination... As part of the diagnosis, doctors check the state of the hormonal background of a woman who dreams of motherhood, examine her health reproductive system after finding out whether the fallopian tubes are passable, whether there are adhesions, as well as ovarian cysts.

If there are no indicated pathologies, then apply complex therapy... After menstruation, a woman is prescribed "Klostilbegit" and she should take it up to the 9th day of the cycle.

Then an ultrasound scan is performed, which determines the size and number of follicles. As soon as one of them reaches the desired size, you can make the hCG angle. The drug is administered at a follicle size of 17 millimeters (the best). For this, the imported drug "Pregnyl" is often used, it has proven itself well.

Thus, "Clostilbegit" helps to prepare the egg for release, and the gonadotropin promotes rupture of the follicle and release of the egg. Dosages and treatment regimen are prescribed for each patient in individual mode, because every woman has her own reasons for infertility, her own characteristics of the menstrual cycle. The prescribed course can be adjusted if it turns out on intermediate ultrasound that the therapy is ineffective, that symptoms of superovulation have appeared - cysts on the ovaries. The task of the doctor in this situation is to prevent their rupture; for this, hormonal treatment is canceled.

Many women who are going to have an ovulation stimulation procedure wonder how long after an injection ovulation occurs. The answer to this question is given by the manufacturers of the Russian-made drug. The official instructions for the use of the drug indicate that the long-awaited moment after the injection comes in hours. Have imported manufacturers the interval is identical.

It is not at all necessary that the angle be unit. As indicated above, the dosage for one injection is from 5000 units, but the injections themselves can be up to three. It all depends on how the female body reacts to the hormonal attack, and whether it is possible to achieve the desired state of the follicle for conception. With IVF, ovulation is stimulated with a single dose of Vedinits. The most effective are injections into the abdomen with a short needle (from an insulin syringe), this intramuscular method of drug administration is most often used.

For more successful planning during the preparation and conduct of ovulation stimulation, a woman is recommended to donate blood for progesterone and estradiol in dynamics, measure basal temperature daily, and also observe the sex life prescribed by the attending doctor.

Post-injection tests

The issue of using various tests after hormonal therapy with hCG drugs deserves special attention. The level of the hormone received by the female body "from the outside", of course, affects the results and analyzes that can be carried out later. Therefore, it is recommended to do an ovulation test no earlier than three days later, and a pregnancy test after an injection will not be informative for at least 12 days. More often than not, the woman will see the second strip, but the result will be false positive.

The concentration of the hormone obtained during the injection leaves the body in about 12 days. Therefore, doctors do not advise starting to buy pharmacy tests earlier than the fifteenth day after ovulation. The best option a blood test for hCG is considered. If you do it several times, then the dynamics will be noticeable. Positive if pregnancy has occurred, and negative (the level will decrease) if conception did not take place.

Pregnancy maintenance

An insufficient level of intrinsic chorionic gonadotropin is primarily manifested high probability early miscarriage. Lack of this hormone leads to insufficient production progesterone - the hormone "responsible" for maintaining pregnancy. Therefore, a low level of hCG can lead to intrauterine death of the embryo and a frozen pregnancy.

If a woman has already had pregnancies according to this scenario, she will most likely be offered hormonal therapy with Chorionic Gonadotropin. If a woman suffers from habitual miscarriage, then she is advised to identify the fact of pregnancy as early as possible using modern diagnostic methods and start treatment with this drug or its analog on time.

It is important that the first injections during early pregnancy are given before obstetric week 8 and completed by week 14. This also applies to cases when a woman first develops symptoms of an early threat of spontaneous abortion.

The dosage, depending on the type of pathology, ranges from 1000 to 3000 units. Injections are given every two days, after 10 weeks - every 3-4 days up to 14 weeks, when the threat is considered a successfully completed stage.

If the problem of miscarriage is malfunction or dysfunction of the corpus luteum, the dosage can be from 1500 to 5000 units for one injection. If recurrent miscarriage is caused by immune or hormonal causes, then the first dose will be in units, and the next dose will be 5000 units. In case of miscarriages of an unclear etiology, the causes of which could not be established, any dosage can be prescribed, except for 10,000, this issue is decided by the attending physician, based on the results of a biochemical blood test.

In the course of a long course of treatment, a woman will have to follow other recommendations, without which hormone therapy may be ineffective. She will have to visit a gynecologist more often, more often do an ultrasound scan to monitor the condition of the cervix and cervical canal, as well as to monitor the growth and development of the embryo, donate blood several times for hormones and biochemical analysis. In case of a serious threat, a hospital stay is recommended.

If problems with conceiving and carrying a baby are associated with endometriosis, the doctor may prescribe hormonal gonadotropin agonists - releasing hormone. Women should understand that such drugs do not affect the ability to conceive a child, they only help prepare a woman's body for further attempts to conceive a baby, help cope with endometriosis.

special instructions

It is a mistake to believe that a single injection of hCG during ovulation stimulation will help cure a woman from anovulation. The drug only stimulates the release of a single egg in a specific cycle. The effect of the drug does not apply to other cycles.

When agreeing to treatment with this hormonal drug, a woman should be aware of such a consequence of gonadotropic therapy as multiple pregnancy. Often, a woman who is stimulated to ovulate with a large dosage of hCG (10,000 units) eventually becomes happy future mother not one, but two or three babies at once.

Many women complain that the lower abdomen hurts after the injection. This should not be scary, because the hormonal injection is quite painful, gradually these post-traumatic pains will go away.

If you take the preparation of human chorionic gonadotropin for too long, then the body may develop antibodies that will interfere with the production of this useful and necessary certain situations substances. This will greatly complicate future pregnancies, making conception and bearing a child practically impossible.

Both the original drug and its foreign analogues are not recommended to be combined with alcohol and narcotic drugs. The question of the compatibility of the hormone with alcohol, which is often heard in many women's forums, generally raises a reasonable answer about the inadmissibility of alcohol during the planning period in general, with an assisted reproductive technique in particular.

How to inject?

Considering that the course of treatment is long, and not all future mothers live next to medical institution, where you can go for an injection, the question arises of how to give an injection of hCG yourself. In fact, it is not difficult if you follow the entire algorithm of actions:

Wash your hands well with soap and water. Better to use an antibacterial soap.

The ampoule with isotonic sodium chloride solution opens first.

A syringe is drawn from it in full.

An isotonic solution is injected into an ampoule with a powder of the drug and mixed well until uniform distribution without precipitation. Stir in a circular motion and in no case shake the ampoule.

The ready-made solution is drawn into a syringe, the needle is changed to a regular one, if it is decided to inject into the buttock, or to a small "insulin" one, if it is planned to inject into the abdomen.

Cotton wool dipped in alcohol or special pharmaceutical alcohol wipes is used to wipe the injection site.

The drug is administered intramuscularly, not quickly.

After the injection, an alcohol napkin is applied to the injection site and lightly pressed for 1-2 minutes.

The method of administration of the drug into the abdomen is most often used to stimulate ovulation. For a systematic intake on a schedule while maintaining pregnancy, it is better to inject chorionic gonadotropin into the gluteus muscle.

Overdose symptoms

Hormone overdose can manifest itself with ovarian hyperstimulation. The appearance of a cyst on the gonads can be indicated by a deterioration in the well-being of a woman. There may be a sharp pain in the lower abdomen, nausea, vomiting. The pain occasionally "shoots" into the groin area. Many women have acute syndrome hyperstimulation there is a feeling of intestinal bloating, distention.

The appearance of diarrhea is possible, but at the same time the amount of urination decreases, the woman begins to swell lower limbs and hands, breathing becomes more frequent.

In more severe cases, a woman's blood clotting is impaired - the blood becomes thicker, peritonitis and acute pulmonary failure may develop. A woman needs to immediately consult a doctor, temporarily stop taking the drug and undergo symptomatic treatment aimed at reducing and disappearing cysts, restoring water-salt and mineral balance, as well as therapy to normalize blood clotting.

Storage conditions and dispensing from pharmacies

The drug belongs to pharmacological group B, it can be bought in pharmacies only with a doctor's prescription. Store boxes with solution and dry powder for dilution at a temperature not exceeding 20 degrees Celsius, so that direct sunlight does not fall on the medicine.

If a diluted solution remains after the injection, it cannot be used again, it is advisable to prepare a new portion of the solution for a new injection, and the remains do not need to be stored at all, either in the first-aid kit or in the refrigerator.

Reviews

Many women in their reviews indicate that it was this drug that helped them get pregnant, gave them a chance to experience real joy motherhood. Most of these patients had already been treated with progesterone and other hormonal drugs in previous pregnancies, but to no avail - there were miscarriages or the pregnancy stopped in development.

Many mothers who have become mothers claim that the drug could have worked not from the first, but from the second or third time, but, compared to years of planning, 2-3 months did not seem like a long time to them. Among the shortcomings, women indicate the high cost of the drug, so for December 2017, the following prices for the original remedy are considered relevant:

packaging of the drug in a dosage of 500 U (5 ampoules + solution) - from 500 rubles;

a package of "Chorionic Gonadotropin" in a dosage of 1000 U (5 ampoules + solution) - from 750 rubles;

packaging of the drug in a dosage of 5000 U (5 ampoules + solution) - from 3200 rubles.

According to women who have left their reviews on this drug on the Internet, such a packaging (5 ampoules) is not very convenient for use, because some do not need more than one or two injections. As a result, the rest of the ampoules remain unclaimed.

The drug is excreted within 2 weeks, pregnancy tests for many show a reliable result after 2-3 days of delay from the day of the expected menstruation, which, fortunately, has not begun.

With regard to another use of the drug - to maintain pregnancy, the reviews are also mostly positive.

all about tests. (grabbed from Eva)

] The phenomenon of separation of a mixture into components when they move with a current of a solvent along a porous carrier was discovered about 100 years ago by the Russian scientist M.S. Color just on mixtures of dyes is what it calls chromatography, or color painting.

If for the experiment we take strips of the same paper of the same length (at the same temperature and humidity), you will notice that the colored spots are always located at the same height. This fact is used in test strips.

Human urine contains in dissolved form a huge amount of substances, including hormones. Most of these substances are colorless and, it would seem, chromatography is useless here - after all, we will not see spots on the strip. However, we can apply to those places where we expect to see the substances of interest to us, special developers, which give a noticeable bright color with the substance to be determined.

This is how tests are arranged not only for pregnancy, but also for other hormones, drugs, and the once popular test strips for nitrates in vegetables, and much more.

Pregnancy tests use immunochromatography - a type of chromatographic analysis based on the interaction of an analyte (usually of a protein nature) with antibodies to it. The same principle of antigen-antibody interaction works the immune system organism, hence the name.

The determined substance is human chorionic gonadotropin (hCG) - a glycopeptide hormone secreted by the placenta during pregnancy. The appearance and rapid increase in the concentration of hCG in the body (and in particular in the urine) of a woman makes it enough reliable sign pregnancy.

Usually on the 7-10th day after fertilization, the hCG concentration reaches 25 mIU / ml (international units per ml) and doubles every 2-3 days, reaching a maximum between the 8th and 11th weeks of pregnancy, and then decreases to almost zero by the beginning of the 3rd trimester.

25 mIU / ml is the minimum concentration of hCG determined using immunochromatographic tests.

The test strip contains a conjugate (loose connection) of anti-hCG antibodies with a dye. When the urine sample moves along the absorbent strip, the conjugate binds to the hCG and forms an antigen-antibody complex. In the zone of positive reaction ("pregnant strip"), the complex binds to anti-hCG antibodies. This releases the dye and forms a reddish-pink streak.

If hCG is absent in the sample, no streak is clearly formed.

In the meantime, the urine moves further, bypasses the zone of positive reaction and reaches the zone of negative reaction ("control strip"). There, unbound antibody-dye conjugate binds to the reagents of the control strip, the dye is released and a second (control) strip of the same red-pink color is formed.

All reactions occur within 3-5, at least 7 minutes.

In low-quality tests, the dye can be cleaved from the conjugate before the entire antibody-hCG-dye complex reaches the reaction zones, forming blurry spots. They are most often mistaken for a "false positive" result. True false positive results are much less common and are caused by very specific reasons. Also, a weak second streak can appear if you "overexpose" the test, ie. read the readings not after the 5 minutes indicated on the package, but later. Such a line arises as a result of the evaporation of water from the surface of the dough, from which the conjugates are destroyed and the dye is released. So you shouldn't wait 10 minutes instead of 5 to “be sure”.

Since not every woman can accurately follow all the instructions and correctly interpret the test results, doctors, especially the old school, are not inclined to trust the tests.

WHAT DEFINES A PREGNANCY TEST?

The pregnancy test determines human chorionic gonadotropin (hCG), a hormone secreted by the placenta from the moment the embryo is implanted into the uterine wall throughout pregnancy. The reliability of this test is very high - there is no placenta, no hCG. HCG can be determined both in blood (in the laboratory) and in urine (in the laboratory and at home).

WHAT DAY AFTER OVULATION IS IT POSSIBLE TO PERFORM THE TEST?

Basically, positive result can be obtained already on the 7th day after ovulation. The embryo implantation takes 6-12 days, usually about 10 days. So it makes sense to wait days after ovulation, but even in this case, there are often false negative results (i.e., there is a pregnancy, but the test is negative).

WHAT DO FALSE POSITIVE AND FALSE NEGATIVE TEST RESULTS MEAN?

A false positive is when the test shows two stripes in the absence of pregnancy. This happens when a woman takes drugs containing hCG, as well as with trophoblastic tumors. After spontaneous miscarriage or early abortion or removal of an ectopic pregnancy, hCG remains in the body for some time, and the test gives false-positive results (i.e. there is no pregnancy, but the test is still positive).

As in the case of taking medications containing hCG, to obtain reliable results need to do two quantitative definitions HCG at intervals of 2-3 days. A decrease in hCG levels indicates that there is no pregnancy.

Thus, false positives are relatively rare as opposed to false negatives. The latter are obtained when the gestational age is still too small and the hCG level is too low to be detected by the test (or the test itself is not sensitive enough).

WHAT IS THE RELIABILITY OF PREGNANCY TESTS WHEN USING ON THE FIRST DAY OF A MONTHLY DELAY?

Tests from different manufacturers have different sensitivity, most of them are designed to be used from the 1st day of delay in menstruation. In 90% ± 5% of cases, by this time the embryo is already implanted into the wall of the uterus and begins to produce hCG. However, in 10% of cases, implantation has not yet occurred.

With a delay of 1 week, implantation occurs already in 97% ± 3% of cases. However, in practice, the reliability of tests is limited by their sensitivity, so the actual reliability is somewhat lower.

Since the hCG level doubles every 2-3 days, a recommendation follows: in case of a negative result, if menstruation does not start, repeat the test after a few days.

HOW LONG SHOULD I DRINK URINE BEFORE THE TEST?

It depends on the time elapsed since ovulation. The most concentrated urine is the first morning urine and is best used. But in principle, if you are testing early, it is enough not to urinate for 4 hours before the test. The higher the level of hCG in your body, the shorter this time. If, for any reason, the test cannot be performed immediately after urine collection, the urine should be stored in the refrigerator (no more than 48 hours) or in the freezer (no more than 2 weeks) before the test.

HOW TO PERFORM ANALYSIS CORRECTLY?

Follow the instructions on the dough packaging. Midstream tests (for use in a stream of urine) can also be used as a normal test (ie dipped in a container of urine), but then all the advantages of the midstream design are lost.

But test strips in a stream of urine CANNOT be used! The urine should be collected in a clean glass, plastic or waxed container; no preservatives should be added. If the test or urine was stored in the refrigerator, it should be allowed to warm to room temperature before analysis, and frozen samples should be completely thawed, mixed thoroughly and warmed to room temperature (do not use a stove or microwave for this!).

WHAT MISTAKES TO AVOID WHEN TAKING THE TEST?

Do not touch the reaction zone of the dough with your hands. The test must be free from moisture or dirt prior to analysis. The test cannot be used after the expiration date. Of course, no foreign matter should be allowed to enter the urine sample. Violation of these rules leads to unreliable results.

WHERE SHOULD THE SECOND STRIP BE LOCATED? DOES ITS BRIGHTNESS MATTER?

On test strips of the simplest design, the upper strip is the control one, and the presence of hCG is shown by the lower one. There are tests in which the control strip forms a minus sign "-", and the second, in the presence of hCG, forms a plus sign "+" with it. In more complex test designs, each strip has its own window, and it is impossible to make a mistake. The brightness of the second strip does not matter, the very fact of its presence is important.

The strip, regardless of the intensity of the color, should be located at some distance from the absorbent pad (or the edge of the window) and have clear edges. If instead of a clear line you see pink spot, the test is invalid. However, if in doubt, it is better to repeat the test in a few days.

CAN THE TEST READINGS CHANGE AFTER ANY TIME, LET'S SAY AN HOUR AFTER ANALYSIS?

A positive result will not change: both stripes were colored and will remain. A negative result after 10 minutes or more may show a weak second streak as a result of the evaporation of water and the release of the dye (the so-called evaporation line). This, of course, does not mean that hCG suddenly appeared from somewhere.

THEREFORE, THE RESULTS OBTAINED LATER THAN 5-7 MINUTES ARE NOT VALID.

A negative result will not become positive either after 10 minutes or after an hour, the second strip should appear within the time indicated on the test package (usually 3-5 minutes). However, if in doubt, it is best to repeat the test a few days later.

CAN ALCOHOL, MEDICINES, ETC. INFLUENCE THE TEST RESULT? Alcohol, medications (and even birth control pills), lactation, menopause, etc. do not affect test results. The only exception is drugs containing hCG (rot, prophasi, etc.). After the last intake of such drugs, you must wait days, otherwise the test result will be false positive.

It is possible to make two quantitative determinations of hCG in the laboratory with an interval of 2-3 days: a noticeable increase in the level of hCG in the second analysis compared to the first indicates pregnancy, while a decrease in the level indicates that the hCG administered with the drug is excreted from the body.

ATTENTION! A PREGNANCY TEST DOES NOT Distinguish a Normal from a Pathological (eg, ectopic) pregnancy. 2) Pregnancy tests can be wrong! Manufacturers of rapid pregnancy tests unanimously promise 99 percent reliability of the results of their products. However, in reality, everything is somewhat different. As you know, home pregnancy tests can be purchased at any pharmacy. Their principle of action is based on the content in the urine of the "pregnancy hormone" - chorionic gonadotropin. In just a few minutes, the strip reacts to the level of concentration and gives the result in the form of one or two strips.

In most cases, the data from such a test can be trusted. However, women who have been struggling for a long time to achieve the desired pregnancy know that the test can show false positive results. It's not hard to guess what joy they felt at the sight of the long-awaited second strip! And what pain and disappointment a visit to the doctor brought them when it was discovered that in fact there was no pregnancy.

If a miscarriage is threatened, the test may suddenly turn negative. It happens that exactly negative result becomes the first sign of an interrupted pregnancy. Poor quality test. If a year ago gynecologists trusted the test results for almost 100%, now they prefer to examine the patient and do an ultrasound. There is one more option: not a single strip is colored during the test. This means that the test is defective.

First. When performing a pregnancy test, errors are possible. First, the test starts working, at the earliest, days after the day of conception. This usually means - from the day the delay started. Therefore, doing a test on days 15, 20, 27 of the cycle is absurd. Although sometimes it is impatient that the first test is done the next morning after intercourse ... So the test done during the last cycle is free to show what he pleases - it's still a wrong result. Wait for a delay. In addition, if intercourse occurred, for example, on the fifth day of a 30-day cycle, then the probability of conception is extremely small (although, of course, there is). Nevertheless, after 12 days, that is, on the 17th day of the cycle, the test will still give a negative result - and this will be true. Due to minor flaws in the methodology (which is very clearly stated in the insert for each test), due to the peculiarities of production, storage, transportation, etc. many tests really start working without errors only starting from 8-10 days of delay. Therefore, if you have a delay, and the test on the second day shows nothing, do not be too lazy to do it again in a week, or even better - donate blood for hCG. No other hormones, foods, stresses, etc. the test result is not affected. Therefore, you should not be deceived, for example, by what the test did against the background of a delay, immediately after intercourse - that's the sperm that gave false result... It is unlikely, rather, the test is right. False negative results can only be in women with kidney disease, renal failure, arterial hypertension, vegetative-vascular dystonia, heart failure, atherosclerosis of the aorta, renal arteries and other diseases in which blood circulation in the kidneys is impaired. However, after a few days, these women will also test positive. In their thirst for a positive answer, many women observe the behavior of the test, not for 5 minutes, as indicated in the instructions, but for two hours! And indeed, finally, they guess some barely visible strip ... Alas, this is not a result, but an influence external factors, which in 2 hours will do something that cannot be foreseen by a single instruction. The tests are for urine only. Neither in the blood, nor in the saliva, hCG is not determined with their help. In any suspicious case, as well as if a very accurate and very early diagnosis of both the presence of hCG and its concentration in the blood is required, a venous blood test is performed. It is carried out in almost any gynecological institution for one day. The accuracy of this analysis is much higher than the tests, because more subtle methods of detecting the hormone are used. Therefore, if the presence or absence of pregnancy is a matter of life and death for you, not the third time for tests, immediately go for an analysis. Blood analysis for hCG is used not only to diagnose the presence of pregnancy, as such, but also to track the course of pregnancy and even for establishing the POSSIBILITY (but not necessarily) of an ectopic pregnancy. There are special tables of the concentration of hCG in the blood at each stage of pregnancy, and at ectopic level HCG is approximately 2/3 of these figures. Therefore, by the way, the test can give a negative result, although the pregnancy develops in the tube.

Our pregnancy calendar reveals to you the peculiarities of all stages of pregnancy - an extremely important, exciting and new period of your life.

We will tell you what will happen to your unborn baby and you in each of the forty weeks.

In this case, the α subunit is identical in hCG, luteinizing hormone (LH), follicle-stimulating hormone (FSH) and thyroid-stimulating hormone (TSH). The difference lies in the structure of the β subunit, which is unique to each of this family of hormones, including hCG.

• The total α subunit consists of 92 amino acids
• The unique β subunit consists of a sequence of 145 amino acids encoded by six highly homologous genes located in tandem and inverted pairs on chromosome 19q13.3 - CGB (1, 2, 3, 5, 7, 8)

Currently, two varieties of hCG are commercially available, having the same amino acid sequence, but different in the method of preparation:

• Recombinant. In other words, the product of recombinant DNA technology. Synthesized by other organisms that have received this ability within the framework of genetic engineering technology. Trade name "Ovitrel".
• Uric. The term does not require clarification, since it implies the same method of extracting the hormone from the urine of pregnant women. It is important, however, to note that over the course of less than a century, technologies for the removal of hCG from urine have undergone significant modernization. And the first two best representatives of the drugs commercially available in Russia practically do not differ from the declared one, as the most "pure" recombinant hCG, characterized by commensurate efficacy and frequency of adverse reactions. Trade names: Pregnil (Netherlands), Horagon (Germany), HCG (Russia).

It is worth mentioning that earlier assumptions about the possibility of using the chorionic hormone of other biologically related species, in particular primates, failed, since the rapidly accumulating antibodies that bind a foreign protein inactivated the biological activity of the injected hormone, which made injections useless. By the way, it should be noted here that in half of women treated with human hCG, for example, in ART cycles, positive titers of antibodies to hCG are also recorded, which nevertheless have no clinical significance.

Mechanism of action in vivo

HCG as a medicine for women. Tasks and mechanism of action in the treatment cycle

Early pregnancy support

Another, but largely controversial negative effect of the use of hCG as part of maintenance therapy is the lack of the practical possibility of early detection of the implanted ovum, due to the impossibility of identifying the true embryonic hCG.

HCG as a trigger

However, the use of hCG preparations was not limited to supporting the luteal phase. Moreover, their main application turned out to be not at all in this. After several years of experimentation, it gradually became apparent that the optimal practical use of hCG is to program the ovulation process (Knobil E et al., 1958).

HCG as a medicine for men

However, it is important to understand that we are so strongly dependent on hCG that virtually the only alternative proposal for a trigger replacement that involves the induction of a peak of intrinsic LH by administration of a GnRH agonist (Lanzone A et al., 1989; Imoedemhe D et al., 1991) is not not only is not able to overlap all stimulation protocols used today, but is also accompanied by a significant decrease in the frequency of pregnancy, due to a serious change in the endocrine homeostasis of the luteal phase. That is why the majority of practicing doctors agreed that the rejection of hCG with the replacement of the trigger by a GnRH agonist is possible and should be practiced only in induction cycles threatened by OHSS, since it is accompanied by the cancellation of the risk of developing moderate and severe OHSS, while allowing to obtain oocytes good quality... However, such a turn almost always implies a two-stage treatment algorithm, followed by the transfer of preserved thawed embryos in a second stage cryocycle (Griesinger G et al., 2007).

In general, hCG demonstrates itself as a real medicine, the best characteristic which will be paraphrased well-known wisdom: “A useful medicine is out of place - poison, useful medicine in too much dose - poison "

Preparations for stimulating ovulation. Injections and pills to help get pregnant

Drugs that help get pregnant are divided into three main types: follicle-stimulating hormone (FSH) and luteinizing hormone (LH) drugs, hCG drugs, and progesterone drugs.

To get pregnant, you need to fulfill three basic conditions:

1) the woman is ovulating;

2) the sperm has fertilized the egg;

3) the embryo is firmly anchored in the uterus.

1) drugs that enhance the production of FSH and LH that help to get pregnant, stimulate ovulation - the growth of follicles on the ovaries;

2) hCG helps the largest follicle to remain large enough and release an egg, which must be fertilized by the sperm;

3) progesterone prepares the inner layer of the uterus for anchoring the embryo and helps to bear the fetus.

A bit of theory: the mechanism of ovulation

Ovulation is the release of a mature egg from the ovary. Then the egg is sent through the fallopian tubes into the cavity into the uterus. This happens, as a rule, in the middle of the cycle, that is, on the 14-15th day after the onset of menstrual bleeding. Women with a regular cycle, most likely, do not ask the question "Will I be able to get pregnant?" With a regular cycle, ovulation usually takes place regularly.

If you came to the doctor with the question “Why I can’t get pregnant” or the complaint “I can’t get pregnant for a year”, then most likely you do not ovulate. Without ovulation, women cannot get pregnant.

If you are interested in the question "Why can't I get pregnant?", You can do an ovulation test. You can buy it at a pharmacy. See your doctor if you are not ovulating for several cycles in a row.

Ovulation may not occur until various reasons: due to hormonal disruptions, inflammation of the pelvic organs, and so on. If you have not been able to get pregnant for a year because ovulation does not occur, your doctor may prescribe injections and pills that help get pregnant - stimulating it.

Who is the stimulation of ovulation indicated for?

If the question "Why can't I get pregnant?" Is relevant for you, then you need to undergo an examination. It is good if your spouse does the same - this would help to establish the cause of infertility.

• The patient has a rare maturation of the egg and its release from the ovaries,
• The couple has been trying unsuccessfully to get pregnant for over a year;
• Spouses over 35–40 years of age do not become pregnant for 6 months.

In this case, stimulation of ovulation is prohibited in the following cases:

• Partner infertility
• The presence of inflammation of the appendages, with andexitis
• With pathologies of the uterus
• In case of poor patency of the fallopian tubes

FSH and LH preparations. The goal is ovulation

Under the action of FSH, follicles begin to grow on the ovary - "sacs" on the surface of the ovary, in which one egg matures. To stimulate the growth of follicles, the following drugs are most often prescribed to help get pregnant:

Drugs that help to get pregnant are selected individually, depending on the test results and ultrasound examination. In this material, we describe the most famous, but far from all existing drugs.

"Pills that help to get pregnant" - this is how "Klostilbegit" is called the women, whom this drug helped to fulfill their dream - to conceive a child. It stimulates the production of pituitary hormones: FSH - to stimulate follicular growth; LH (luteinizing hormone) - to stimulate ovulation, that is, the release of the egg from the follicle; prolactin - for the production of milk in the mammary glands.

According to the instructions, these pills that help to get pregnant should not be taken more than 5-6 times in a lifetime. Otherwise, early depletion of the ovaries is possible, as a result of which pregnancy will be impossible, since all the eggs will be used up. Stimulation of the maturation of the egg with the drug "Klostilbegit" is carried out, as a rule, from the 5th to the 9th day after the onset of menstruation. These pills to help get pregnant are taken 1 piece once a day.

This drug negatively affects the growth of the endometrium. If ultrasound shows that the endometrium is thinner than 8 mm, then another drug must be used to stimulate ovulation. On a thin endometrium, it will be difficult for the embryo to gain a foothold in the uterus - and the answer to the question "can I get pregnant" will be negative, despite the fact that conception occurs.

Puregon is included in the list gonadotropic drugs, as it stimulates the production of sex hormones by the pituitary gland - FSH and LH. Puregon helps the ovaries to grow several follicles, which makes it possible for ovulation to occur in the middle of the menstrual cycle. Suitable for stimulating ovulation in both natural conception and in vitro fertilization in the IVF program.

Replenishes the lack of sex hormones FSH and LH, which in turn increases the concentration of estrogens - female hormones. As a result, follicles on the ovaries begin to grow, and the inner layer of the uterus (endometrium) grows and prepares for a possible pregnancy.

"Puregon", "Menogon" and other gonadotropins (activating the pituitary gland) begin to take on the second day of menstrual bleeding. Duration - 10 days, but it must be adjusted with a doctor, as well as monitor the reaction of the ovaries using ultrasound.

HCG preparations

After the ultrasound shows that the follicles have grown to the desired size (20-25 mm), injections of human chorionic gonadotropin (hCG) are prescribed. These are also hormonal drugs that help get pregnant. HCG is administered one day after the last intake of Menogon, Puregon and other drugs. The hCG hormone contains the preparations "Pregnil", "Horagon", "Profazi", "Gonacor" and others. Preparations of the hCG hormone are prescribed once in a dose of 5000–10000 IU. One day after the injection, ovulation occurs. In order for the therapy to help, one day before the injection of drugs with hCG and another 24 hours after, it is necessary to have sex.

If the result of the action of the above drugs is positive, then progesterone drugs are prescribed. They help "fix" the pregnancy. "Duphaston" and other progestin-only pills that help to get pregnant are prescribed individually.

In many cases, hormone therapy, the scheme of which is described above, helps women to cope with the problem "I can not give birth and bear a child." With the development of medicine, more and more more women get the opportunity to feel the happiness of motherhood and forget about the times when they started topics on the forums with the heading "I can't give birth."

Frequently asked questions related to getting pregnant

The likelihood of getting pregnant with polycystic ovary is very low. The larger the number and size of cysts, the less chance conceive a child.

The presence of myomatous nodes significantly reduces the likelihood of pregnancy. The larger the diameter of the nodes, the less chance of pregnancy.

There is a chance of conceiving a baby with a diagnosis of endometriosis, but very small. Severe stages of endometriosis can cause infertility.

There is a possibility of getting pregnant, the likelihood of an ectopic pregnancy is high. It must be removed surgically. However, you can get pregnant with IVF - the fertilized egg is implanted into the uterus, and the obstruction of the tubes will not be a problem. In this case, the answer to the question "Will I be able to get pregnant" is positive.

When the uterus is bent, the diagnosis is "infertility", but this is not a sentence: there are women who successfully bear several children when the uterus is bent.

If during a previous pregnancy you were unable to give birth, bearing the fetus for 9 months, you need to find out the reason. There is a chance of getting pregnant.

You can conceive, but you need to find out why you could not stand previous pregnancies.

There are chances, but there may be problems maintaining the pregnancy. Hormone therapy will help.

Erosion, or ectopia, does not affect the ability to become pregnant.

A woman can get pregnant before menopause.

It does not affect the probability of conception, but it can cause disturbances in the development of the fetus.

Medical abortion does not affect your ability to conceive in the future.

The thickness of the endometrium does not affect the likelihood of conception. But on a thinned embryo the embryo will not be able to "take root", and the pregnancy will not survive.

Probably yes. However, if you have had an ectopic pregnancy, the chances are high that the new zygote will also not be able to enter the uterus and anchor in the tubes. Talk to your doctor about how to prevent another ectopic pregnancy.

Probably yes. It is advisable to find out the reason why menstruation is irregular in order to exclude hormonal problems and other abnormalities that may affect the course of pregnancy.

Sexually transmitted infections, especially sexually transmitted infections, are the second in the list of causes of infertility. In such cases, the chances of conceiving are very low.

Folk remedies to stimulate ovulation

Exists a large number of so-called folk remedies that can stimulate ovulation and help self-conception, but their effectiveness has not been proven by experts.

When stimulating ovulation at home, you can use decoctions of sage, plantain and aloe, which motivate necessary process... The result is obtained due to the content of phytoestrogens in herbs, which can work in a similar way to female hormones, provoking the release of an egg from the ovaries. The effect of decoctions is most effective in the first period of the menstrual cycle. For the second period, a decoction from the borax uterus is more suitable, since this drug is more similar to progesterone secreted by the female body and contributes to the consolidation of the embryo. You can stimulate ovulation using essential oils based on cypress, basil and anise, which also stimulate the body's production of estrogen. Helps to stimulate ovulation special diet as well as reception vitamin preparations, but these details are worth discussing with a fertility specialist and nutritionist, who will help you choose the most effective and relevant ways.

HCG injection

Carrying out a pregnancy without human chorionic gonadotropin is impossible. In our article, we will analyze the role of this hormone in the onset of pregnancy and the principle of its action.

Intended use of hCG injections

If the natural interaction of hormones in the female body is disrupted, the process of follicle growth or egg release may be disrupted or even absent. In such cases, after a complete examination and establishing the cause of the problem that has occurred, an ovulation stimulation scheme is selected, in which the hCG injection plays a significant role in starting this process.

HCG is a pregnancy hormone. In a natural state, the placenta begins to produce it from the moment of its formation and continues until delivery.

He is also able to help the release of the egg from the ovary and support the work of the corpus luteum, which produces progesterone until the placenta is formed, which then continues this process throughout the pregnancy.

V normal condition HCG is produced by the placenta

In what cases is hCG prescribed

An injection of hCG 10,000 is prescribed when ovulation does not occur (to start it). Previously, the entire first phase, according to the scheme selected by the doctor, estrogen substitutes stimulate the growth of the follicle to the desired size. It is monitored by ultrasound. This study first occurs a couple of days after the course of the hormone and continues at the same interval until the doctor fixes that the liquid bubble has reached a diameter of mm. At this moment, the drug is injected. The injection is given 2-3 days after the last dose of the stimulant.

Ovulation after an injection of HCG occurs after hours. With a planned pregnancy, this period of time, plus one more day, is the most favorable for conception. Therefore, intercourse is necessary on the day of the injection and the next two days.

The cell exit time can be determined using urine tests. They begin on the day obtained by subtracting the number 17 from the length of the regular menstrual cycle. If the cyclicity is violated, then 17 is subtracted from its smallest duration.

The moment of onset of ovulation after an injection of hCG can be identified using tests

HCG types

This drug is obtained from the urine of women carrying children. It is sold in ampoules with a solution in doses of 500, 1000, 1500, 5000 IED. The names can be different:

• chorionic gonadotropin;
• rotted;
• horagon;
• eco-stimulin.

HCG price

The cost is different everywhere. It depends on brand, dosage and volume of packaging (number of ampoules). The price of a hCG injection is on average rubles.

So, the hCG injection performs the functions:

• maintaining the growth of the corpus luteum until the placenta produces progesterone;
• helping the formation of the placenta itself;
• stimulation of ovulation and support of the corpus luteum.

How long does an injection of hCG go?

Many people are interested in the question of how much the injection of hCG 10,000 comes out. It is difficult to give an answer to it. Each female body reacts in its own way to medications, the elimination period is different for everyone. Only a blood test for this hormone can confirm its level at the moment.

Using a blood test, you can determine the level of the hormone hCG in the blood.

At the onset of pregnancy, how much an injection of hCG 10,000 is excreted is generally difficult to say, since developing placenta she begins to develop it. The analytics carried out in this case shows an ever-increasing importance. So, where the action of the injection ended, and the work of natural gonadotropin began, it is almost impossible to determine.

Other uses of hCG

HCG is used not only in the absence of ovulation, but also in other cases:

• to maintain the function of the corpus luteum;
• with a habitual miscarriage;
• threatened miscarriage;
• in violation of the menstrual cycle;
• to prepare for IVF.

If this injection is prescribed, you need to know in what cases it cannot be used. Treatment is contraindicated:

• with cancer of the female genital organs;
• individual intolerance;
• with some diseases of the thyroid gland;
• early menopause;
• tendency to blood clots;
• with obstruction of the fallopian tubes;
• during breastfeeding.

When the pregnancy comes

The medicine fulfilled its role, the egg was released from the ovary and moved into the fallopian tube to meet with the sperm. In anticipation of fertilization, the drug continues its action, supporting the corpus luteum, helping it to produce progesterone, which is necessary for the completion of conception and preparation of the uterus for the adoption of the ovum.

HCG supports the corpus luteum formed after ovulation

Pregnancy field of injection of hCG occurs approximately in 7 days from the moment of ovulation. Such a period of time is necessary for the embryo to descend into the uterus and attach to the endometrium. The placenta is immediately formed, which itself begins to produce chorionic gonadotropin, because its content increases.

And even the fact that pregnancy occurs a week after ovulation will not show the full picture if a test is carried out on the 10th day after an injection of hCG 10000. Due to its high content in the blood, you can get a false positive result.

It is too early to start testing 12 days after the HCG injection. You need to wait 1-2 weeks. But if you can't wait to confirm a fait accompli, you can have a blood test. With a periodicity of every two days, growth dynamics is observed. If the indicators continue to increase steadily, this will be a confirmation of the successful development of the embryo.

In any case, prescribing an injection of hCG 10,000, when the pregnancy tests are done, the doctor decides, who develops the regimen and treatment individually, adjusting to the characteristics female body and data from all surveys.

which hCG drug to buy? Help

Ovitrell also does not need to be diluted by itself, everything is already in the syringe, you just need to sit down and insert the needle into the fold of the abdomen (the needle is about 1.5 cm) the entire needle.

HCG is pricked when the follicle is already more than 20mm, it bursts the follicle faster. But I don't know about the dosage for you, I have PCOS and the gynecologist said that 5000 is not enough, you need units

As for hCG, I don't know how to breed it, or how to put it, maybe the girls will tell you

thank you very much! I hope I will get lost in this cycle too!

And ovitrel and rot are the same hCG, only imported. The action is exactly the same.

Tell.

Instructions for the use of chorionic gonadotropin - indications, dosage and side effects

Testosterone production plays important role in the functioning of the body of men and women. The drug Chorionic Gonadotropin in the form of injections, according to the instructions for use, solves an important task - to increase its level in case of deviation from the norm. What other effect the drug has, for what problems it is prescribed, how to use it correctly - about this in detail in the annotation.

What is chorionic gonadotropin

This is the name of the hormone responsible for puberty, reproductive function. What is hCG for a woman's body? This is a substance that is actively produced after the fertilization of the egg. Refers to gonadotropic hormones, but differs in the sequence of amino acids. Excess hCG norms confirms the onset of pregnancy. This determines the pharmacy test that responds to its content in the urine. Increasing hCG in non-pregnant women, it can signal the presence of a malignant tumor.

The introduction of the drug causes an increase in the production of sex hormones in men, the development of secondary sexual characteristics, and stimulates the activity of sperm. During use in women:

• the production of estrogen, progesterone by the ovaries increases;
• ovulation is stimulated;
• the function of the corpus luteum is normalized;
• the placenta is developing correctly.

Composition and form of release

Gonadotropin is available as two ingredients in a box. Each contains 5 sets of medication. The composition has:

• The solvent is a saline solution of sodium chloride with a concentration of 0.9%.
• Sterile glass vial with substance in powder form white, contains 500 or 1000 IU - units of action. The basis is human chorionic gonadotropin derived from biological material, past process lyophilization - drying in a vacuum. The auxiliary component is mannitol.

pharmachologic effect

Recombinant chorionic gonadotropin - a hormone produced by the placenta, is excreted from the body in the urine of a pregnant woman, from where it is extracted to obtain a medicine. When administered as an intramuscular injection, it produces a therapeutic effect. Active substance:

• after 15 minutes enters the bloodstream;
• spreads in tissues;
• excreted in the urine;
• the half-life is 8 hours.

The drug Gonadotropin belongs to the hormones of the hypothalamus:

• In women, it normalizes the function of the ovaries, activates the formation of the corpus luteum, stimulates the production of progesterone, estrogens. Application promotes luteinizing action - the correct ovulation process.
• Gonadotropin for men helps the formation of secondary sexual characteristics, stimulates spermatogenesis. The tool accelerates the descent of the testicles into the scrotum in the treatment of cryptorchidism, activates the production of the hormone testosterone.

Indications for the use of chorionic gonadotropin

• infertility as a result of hormonal disorders;
• late puberty for girls and boys;
• violation of the reproductive function of offspring;
• decreased synthesis of sex hormones.

For men

A decrease in gonadotropin levels creates serious problems in organism. HCG in men is responsible for the activity of sperm, the production of sex hormones. The remedy is prescribed if:

• cryptorchidism;
• violations reproductive function;
• insufficient activity of the gonads;
• hypoplasia of the testicles;
• spermatogenesis disorders;
• the phenomena of eunuchoidism;
• hypogenitalism.

For women

The hormone gonadotropin plays an important role in the treatment of female infertility caused by dysfunctions of the corpus luteum. It helps to get pregnant in the absence of ovulation, when the follicle cannot burst to fertilize the egg. The indications for the use of the drug by women are:

• ovarian dysfunction;
• uterine bleeding during childbearing age;
• the threat of miscarriage in the first trimester;
• irregularities, absence of the menstrual cycle.

Instructions for the use of chorionic gonadotropin

The medicine is administered intramuscularly. How to inject gonadotropin? The methodology, the duration of the course, is determined by the doctor, which depends on the disease, the planned result. The duration of therapy is up to 45 days. There are features:

• In men, treatment with the agent is used 3 times a week for a month, the dose is up to 3000 IU. This is followed by a six-week break and a new course. This can be repeated 3 times per year.
• The medicine is prescribed to boys with cryptorchidism with a dosage of 1000 IU twice a week for one and a half months. Several courses are being held.

Treatment for women depends on the problem:

• to stimulate ovulation - one injection of ME;
• if there is a threat of miscarriage, ME are administered for the first time, then twice a week, 5000 IU;
• in the case of anovulatory dysfunction with a high level of estrogen, the injection is carried out on the menstrual cycle, the dose is 3000 IU, 2-3 injections with an interval of several days;
• to normalize the production of the corpus luteum - up to 5000 IU on the 3rd, 6th, 9th day after ovulation.

In bodybuilding

The use of gonadotropin by athletes along with the use of steroids has mixed assessments. Professionals do not confirm high results after taking hormonal drugs. Gonadotropin in bodybuilding with high dosages provokes dysfunction of the testicles, hypothalamus, pituitary gland. There are groups of bodybuilders who use the product for a long time and note:

• getting a beautiful muscle relief;
• increasing endurance in training;
• stimulation of spermatogenesis;
• increased sex drive.

During pregnancy

Care should be taken when treating with gonadotropin during pregnancy. Gynecologists prescribe a medicine in exceptional cases, the course is carried out in stationary conditions under the strict supervision of a physician. When using the drug, an adverse effect on the body of a pregnant woman is possible:

• increased risk of miscarriage;
• the development of multiple pregnancies.

special instructions

Instructions for use require excluding the interaction of gonadotropic hormones with glucocorticosteroids. Long-term administration of the drug can lead to the formation of antibodies to it. Special instructions during use:

• it is not recommended to drive a car, work on units that require high concentration attention;
• combination with alcohol is not recommended;
• when treating men, the level of androgens rises - a doctor's supervision is necessary.

Annotation to the drug stipulates important points:

• solution for injection is prepared before use, storage is unacceptable;
• if ovarian hyperstimulation syndrome occurs, treatment must be stopped;
• you need to stop feeding during treatment during lactation;
• with prolonged administration, the functions of the pituitary gland decrease;
• the medicine cannot be used after the expiration date.

Side effects of chorionic gonadotropin

It is unacceptable to self-medicate, in case of an overdose, serious side effects are inevitable. Unpleasant symptoms can affect many systems. In this case, the reactions of the body are observed:

• weakness;
• depression;
• irritability;
• headache;
• increased fatigue;
• anxiety;
• increase in body weight;

Chorionic gonadotropin is a biologically active substance, a hormone that is part of drugs that are used when there is hypofunction of the female gonads (decreased activity), as well as the gonads in men, which is based on a disorder of the hypothalamic-pituitary system.

pharmachologic effect

The suppression of the function of the gonads can occur due to many reasons, including genetic disorders. Such diseases can be of a primary or secondary nature. In the latter case, the cause of the disease lies in other factors, one way or another, affecting the growth and development of the gonads.

Preparations containing chorionic gonadotropin have a gonadotropic effect, therefore, stimulate the activity of the female and male genital glands - the ovaries and testicles.

The mechanism of action of the drug is based on the activation of gonadotropin-specific receptors, as a result of which the activity of the gonads is normalized, other processes regulated by testosterone and estrogens are triggered.

The use of chorionic gonadotropin preparations in men helps to stimulate the development of the testicles, activates the reactions underlying spermatogenesis, therefore, increases the volume of ejaculate. It is a factor in the development of secondary sexual characteristics.

In women, under the influence of drugs, the reactions of biological synthesis of estrogens are stimulated, ovulation occurs, the secretory activity of the corpus luteum appears, the cycle normalizes, and other important processes are activated.

The action of chorionic gonadotropin is similar to its biological analogue - luteinizing hormone, but unlike the latter, it lasts for a much longer period of time, since it is characterized by a longer half-life.

Chorionic gonadotropin preparations are used both for congenital dysfunctions of the gonads, and for acquired ones. With cryptorchidism, this substance contributes to the descent of the testicles and the normalization of their functional component.

With the introduction of drugs of chorionic gonadotropin, the therapeutic concentration is created after 30 - 40 minutes. The half-life is about 8-10 hours. The drug is excreted in the urine.

Indications for use

The appointment of the substance chorionic gonadotropin is possible for the implementation of replacement therapy in the presence of the following diseases:

Delayed sexual development;
Anovulatory ovarian dysfunction (lack of ovulation);
Insufficiency of the corpus luteum of the luteal phase of the menstrual cycle;
Uterine bleeding in women of fertile age;
Hypogonadotropic hypogonadism;
Testicular hypoplasia;
Eunuchoidism;
Pituitary dwarfism;
Disorders of spermatogenesis.

The use of such drugs is possible only with the explicit approval of a specialist who has the results of laboratory and instrumental studies. Use without proper control, for example, in sports practice, can have extremely negative consequences.

Contraindications for use

The appointment of chorionic gonadotropin drugs should not be carried out in the presence of the following conditions:

Oncological pathology of the pituitary gland;
Hormone-dependent prostate tumors;
Mammary cancer;
Lack of genital glands;
Individual intolerance to chorionic gonadotropin;
;
Ovarian cysts;
Early menopause;
Premature sexual development;
Age less than 4 years old;
Arterial hypertension;
Migraine conditions;
Severe kidney disease.

In addition, do not use the remedy for epilepsy.

Application and dosage

The dosage of the drug is determined by the indications for use and the level of luteinizing hormone and can vary from 500 to 10,000 IU. The solution for administration is prepared immediately before use. For dilution, use the supplied diluent. The finished medicine is not subject to storage, therefore, it should be used immediately.

In the absence of ovulation, 3000 IU should be injected intramuscularly starting from 10, 12 days of the cycle. Usually 2 or 3 injections are given at intervals of 3 days.

Overdose

Given the extremely low degree of toxicity, there is no reason to talk about the possibility of an overdose of chorionic gonadotropin preparations. Such cases have not been recorded at the present time.

Side effects

From the side of the glands internal secretion: reversible enlargement of the mammary glands in men, water retention, sodium retention, acne, significant enlargement of the testes, premature puberty, testicular or ovarian atrophy, decreased sperm count, ovarian cysts, multiple pregnancies.

From the side nervous system: depressive states, persistent headache, irritability, unmotivated anxiety, increased fatigue, weakness, apathy.

Preparations containing chorionic gonadotropin

This substance is contained in the following medicines: Horagon, Prophazi, Pregnil, Gonacor, Chorionic Gonadotropin.

Conclusion

Human chorionic gonadotropin for whom we have given instructions, use, indications, contraindications, action, side effects, analogs, composition, dosage, is prescribed when there is hypofunction of the gonads of the pituitary gland and hypothalamus. Violations of the genital glands are most often determined during puberty. Therefore, adolescents in mandatory should have regular medical examinations, during which specialists may suspect the presence of pathology and prescribe adequate treatment in time.

In the human body, the hCG hormone plays an important role. It is responsible for the reproductive function of the female and male genital organs, and also supports the development of the fetus in the womb. The lack of this hormone affects the ability of women to conceive, therefore gynecologists in such cases prescribe an injection of hCG.

The drugs, which include human chorionic gonadotropin, are used to treat men and women. The active ingredient can be obtained in several ways. Most manufacturers extract it from the urine of pregnant women, but some synthesize a special protein using recombinant DNA.

There are many medicines containing hCG or its synthetic analogues, for example, Humegon, Pregnil, Ovitrel. Doctors sometimes prescribe additional agents for the treatment of infertility: Dipherelin, Luveris, Duphaston, etc.

Release form and composition of chorionic gonadotropin

Chorionic gonadotropin is produced in the form of a special powder, from which a solution is made for intramuscular injections. The powder is obtained by lyophilization - vacuum drying of biological material. This allows you to significantly extend its shelf life. The drug is packed in sealed glass ampoules or vials. They are placed in plastic or cardboard boxes of 5 or 10 pieces. The package should also contain ampoules with a solvent - sodium chloride solution at a concentration of 0.9%. They need to dilute the powder until it is completely dissolved. In addition to the main component, the preparation also contains mannitol, which prevents dry matter from clumping and promotes its uniform dissolution. It is a neutral ingredient.

More often in pharmacies you can find chorionic gonadotropin 1500 IU, but there are other dosage options:

• 1000;
• 3000;
• 5000;
• 10000.

The concentration of the drug is selected individually based on the diagnosis and prescription of the attending physician. The composition of the drug from different manufacturers may differ slightly, all this is indicated in the annotation-insert in the package, the price may also differ. Store the drug in a cool place without direct sunlight.

Gonadotropin injection

Intramuscular injections of the drug are prescribed for various deviations in the work of the reproductive system. Throughout the entire period of therapy, the patient is under observation and undergoes control tests.

Purpose and indications for HCG injection

The drug is prescribed for the treatment of infertility in women and men, as well as for maintaining the natural hormone levels in the body during pregnancy. Depending on the purpose, the scheme of injections varies, as well as the duration of the course.

There are a number of indications for which the administration of gonadotropin is prescribed:

• Stimulation of ovulation. In the event that a woman has problems with the development of eggs, injections of the drug help this process to proceed more actively. True, the likelihood of an ectopic pregnancy increases.
• Reduced risk of cyst growth. The hormone prevents the follicle from shrinking and forming benign tumor inside the ovaries. Normally, the follicle bursts and the cyst does not develop.
• Maintaining the corpus luteum in the early stages of pregnancy. Because of hormonal imbalance it can flake off and cause miscarriage.
• Carrying out artificial insemination and preparation of the female reproductive system for the transfer of embryos into the uterine cavity. In the process of such ovulation, not one follicle is obtained, but several at once.
• Elimination of the danger of early pregnancy failure if there has already been a negative experience earlier.
• Availability cystic skid during previous pregnancies.

Such injections help not only to conceive a child, but also to endure it. With a correctly calculated dosage, it is possible to treat infertility in women with hormonal imbalance.

Stimulation of ovulation

An injection of hCG to stimulate ovulation is used if it cannot pass naturally... The causes of the problem are different, but the most common are tumors, drugs that suppress reproductive function, and polycystic ovary disease. Injections are prescribed only on the basis of decoding the data obtained from the test results for the level of hormones in the body.

Ultrasound of the pelvic area, as well as a table of measurements basal temperature the patient plays an equally important role. The drug stimulates the onset of the ovulation period, regardless of what happens next to the mature egg. She will either be fertilized naturally, or will be withdrawn for the IVF cryoprotocol.

Treatment with a hormone begins from the first day of menstruation, and if the cycle is knocked down, then from the first supposed day of menstruation. It is worth considering the fact that oral contraceptives should be canceled no later than 5-7 days before the start of therapy. During the stimulation of ovulation, alcohol, drugs should not be consumed, smoking is not recommended. This can negatively affect the reproductive processes in the body. It is worth limiting physical activity, as well as protecting a woman from stress and anxiety. It is recommended to avoid sex during this period. Sexual intercourse will be effective only 5 days after ovulation.

When is testing done after a hCG injection?

After a woman has been given an injection of gonadotropin to stimulate ovulation, at least 3 days must pass before the egg is released from the follicle. Sometimes it takes just over 24 hours. At the same time, increased production of progesterone begins.

Depending on the length of the cycle, ovulation tests after an injection of hCG begin to be done:

• 17 days before the start of your period, if the cycle length is known and constant.
• 15 days before the start of your period if the cycle length is not constant. To calculate the day, take the shortest cycle in the last 6 months.

Every day after diagnosing follicle proliferation using ultrasound. This option is appropriate if there are long delays and breaks in the cycles.

There is a huge variety of tests that differ not only in cost, but also in sensitivity. It is better to choose which test to use with your doctor.

Contraindications for hCG injection

Like any hormonal drug, injections of chorionic gonadotropin have some contraindications. They are more associated with tumor neoplasms, as well as with some individual characteristics of the body.

Injections are contraindicated in the presence of any inflammatory processes associated with the reproductive system. This applies to both women and men. You can not inject the drug if there is a pituitary tumor, as well as malignant neoplasms in the ovaries.

Women with early menopause are also not advised to use gonadotropin in medicinal purposes... The same applies to mothers who breastfeed their children, since the hormone enters the milk through the blood. Because of this, deviations in the development of the child's genitals may appear. If there is a suspicion or an established diagnosis of obstruction of the fallopian tubes, the doctor does not prescribe hCG injections. You can not use the drug for thrombophlebitis and chronic inflammatory processes in the adrenal glands.

Instructions for use

Regardless of the diagnosis, gonadotropin is administered intramuscularly. When planning a pregnancy, before using the drug, it is recommended to undergo full examination... When stimulating the ovulation process, one-time injections are used with a dosage of 5,000 to 10,000 IU. If there is a need to maintain the corpus luteum, then the drug is administered on the 3rd, 6th and 9th day after the onset of ovulation, the dosage is 1500-5000 IU.


Stimulation of superovulation for egg collection for IVF is also carried out with the help of injections of gonadotropin. To do this, enter 10,000 units once. After 34–36 hours, oocytes are removed for their further fertilization. This is done when a woman cannot get pregnant on her own. If there is a likelihood of spontaneous abortion, and the symptomatology manifested itself no later than 8 weeks, the woman is injected with 10,000 units on the first day and then 2 times a week at 5,000 units. Therapy lasts up to 14 weeks. If a woman's previous pregnancy was interrupted due to a lack of the hCG hormone in the body, then when diagnosing the next one, as a prevention of miscarriage, the same dosage is prescribed as with the threat of miscarriage.

Boys, when diagnosing delays in sexual development, are prescribed from 3000 to 5000 IU 1 time in 7 days. The duration of the course is at least 3 months, after which, if necessary, a repetition is possible. Men are injected with 500-2000 IU 2 times a week. The duration of therapy is 1.5–2 months. If idiopathic normo-hormonal oligospermia occurs, then it is treated with a weekly injection of 5000 IU of gonadotropin in combination with menotropin (menopausal gonadotropin). The course lasts 12 weeks. If the disease has developed due to androgen deficiency, 2500 U of the hormone is injected every 5 days for 3 months.


Gonadotropin drugs can cause some side effects. Most often they occur with an overdose. Women may show signs of ovarian hyperstimulation and a significant increase in their size. During this time, the chest and lower abdomen may also hurt. At allergic reactions redness may appear at the injection site, as well as a feeling of itching and pain. The general condition and well-being of the patient may deteriorate significantly. The drug is excreted by the kidneys, so attempts to check for pregnancy using test strips do not give the correct result. An increased concentration in non-pregnant women can be observed for another 36–45 hours after the last injection.

Chorionic gonadotropin for men

Chorionic gonadotropin is used to treat diseases of the reproductive system in men. In addition, the drug is used by athletes. If the functionality of the testicles in boys is assessed in the diagnosis of cryptorchidism or anarchism, an injection of 5000 IU is practiced once. For the treatment of cryptorchidism, gonadotropin is used in a dosage of 500-1000 U, if the patient is less than 6 years old. The drug is injected 2 times a week for 1.5 months. For children over 6 years old and adults, this dosage increases to 1500 units.

Athletes often use testosterone and its analogues in bodybuilding to obtain high sports results. As a result, testicular atrophy occurs. Gonadotropin is able to prevent this problem.

If you replace injections with a drug in tablets, this will not have the desired effect, although many manufacturers claim the opposite.

Most often, hCG is needed if an athlete starts taking Trenbolone - a very strong steroid for recruiting muscle mass... Previously, it was used only in veterinary medicine. PCT (post cycle therapy) in this case - required condition to maintain the reproductive function of the genitals.

In case of an overdose of the drug in men, there is an increase in the sensitivity of the nipples, gynecomastia, as well as an increase in the size of the inguinal testicles. Prolonged overdosing also has negative consequences. It causes a sharp decrease in the number of active viable sperm in the semen.

Hormonal drugs based on gonadotropin have good reviews from patients who have been treated for infertility or used a medicine to maintain pregnancy.

It is not necessary to wait for an ultrasound scan, a doctor's examination or a test result to find out about a long-awaited conception. The fastest and most exact result will give a blood test for hCG, which is done after ovulation and shows how long the pregnancy is. This test determines the level of the hormone hCG in a woman's blood, which is produced by chorion, one of the fetal membranes the embryo. Pregnancy tests work on the same principle, but their sensitivity is not so great, and besides, the result can be false positive or false negative. In this regard, a blood test will be much more accurate and will be able to determine pregnancy much faster than tests. Its value is quite large:

• If you donate blood for several days, at intervals of a day, then by the growth of hCG you can determine whether pregnancy is developing.
• The analysis will be able to tell at a fairly early date whether your pregnancy is multiple or not.
• According to the results of the study in dynamics, it is possible to determine whether the pregnancy is frozen or not.
• In addition, monitoring hCG over time will help establish whether the ovum has been removed from the uterine cavity, or whether the pregnancy continues to progress. This is shown in cases where the pregnancy had to be terminated for a short period of time for medical reasons.
• An increase in hCG in non-pregnant women and in men will indicate possible development various diseases, and this will allow such people to see a doctor as soon as possible.

Thus, a blood test for hCG is important not only during pregnancy or planning it, but also in other situations that require medical supervision.

When to get an HCG test

Despite the fact that the level of hCG in the blood is most likely to herald the presence of pregnancy, this does not mean that you can donate it a few hours after intercourse during ovulation. The fact is that this hormone begins to be produced only when the ovum is implanted to the wall of the uterus (or to the wall of the fallopian tube, if the pregnancy is ectopic). Implantation does not take place during the first hours of conception. V in the overwhelming majority of cases, it does not occur even in the first two or three days after fertilization of the egg. According to observations, implantation of the ovum can occur no earlier than 4 days after ovulation, and the main percentage falls on 5-6-7 days. In total, implantation can occur on any day from 4 to 12 days after ovulation.

If you are keeping a basal temperature chart, it may show characteristic decrease temperature during this period: for one day it will drop by 0.3 - 0.4 degrees. For example, it can drop from 37.4 to 37.0 degrees. This is called implantation retraction, and it means that from now on, the embryo begins to produce the hCG hormone, which can now be found in the blood of its mother.

In this regard, many women ask themselves the question: when to take a blood test for hCG? Experts recommend doing this no earlier than a week after the expected ovulation. And it is advisable to donate blood not once, but at least two times, in order to make sure that the pregnancy is alive and progressing in its development. A little later by the indicator increase hCG I can be sensitive tests for pregnancy: at first, their test strip will be dim, but if you repeat the procedure with a test of the same brand after 48 hours, then you can see progress in coloring.

It is important to know some of the features of blood sampling for this test:

1. HCG is given on an empty stomach, the break should be at least 5 hours, starting from the last meal;
2. blood is taken from a vein for analysis;
3. the analysis for hCG must be taken no earlier than 7 days after the expected ovulation;
4. blood donation is desirable in the morning, when the break between meals will be quite long.

Now you can get the test results for hCG by e-mail, just a few hours after the blood was taken. This helps to act quickly if a hormone is suddenly detected, and a woman, for example, has a lack of progesterone.

HCG hormone and drugs containing progesterone

There is a category of women who have and in the second phase of the cycle they have to take special drugs that artificially increase the level of this hormone in the blood. As a rule, it is either Duphaston or Utrozhestan in various dosages prescribed by the doctor. In this regard, such women often ask themselves the question: how to take hCG if you have to take hormonal drugs? Will they affect the analysis result?

To answer this question, let's turn to what is progesterone. This is a hormone that is produced by the adrenal glands and which is indispensable during pregnancy: it helps her to stay, successfully implant and develop, bypassing detachment and regression. In turn, we know that hCG is a hormone that is secreted not by the woman herself, but by the ovum. Thus, it is obvious that taking Duphaston or Utrozhestan is not able to affect the blood test for hCG, causing the result to be false positive.

However, these two hormones are related, but only in the sense that progesterone helps pregnancy stay in the uterus and develop. Accordingly, the level of hCG also increases, because future baby alive. If there is no pregnancy, and progesterone is being taken, then the test result will still be negative.

HCG growth in ectopic pregnancy

With an ectopic pregnancy, the increase in the level of hCG in the blood has a completely different dynamics. With the uterine attachment of the ovum, the hormone doubles its amount in a woman's body every 48 hours. However, in a fallopian tube pregnancy, hCG growth will not be so fast. If a woman looks at the dynamics of several of her tests, she will notice that the doubling of the level of this hormone will not occur in 48 hours, but only after a few days. Of course, the final diagnosis can only be made by ultrasound and after examination on a gynecological chair, but early observation of a blood test for hCG in dynamics will determine an ectopic pregnancy much earlier than it usually happens. This will help remove the ovum from the fallopian tube, avoiding rupture and thus avoiding a direct threat to the woman's life.

The rise and fall of hCG in frozen pregnancies

A frozen pregnancy only in rare cases gives a slight increase in the level of the hormone. Deciphering the analysis in dynamics, usually, shows that immediately after the death of the embryo, this hormone begins to break down in the woman's body. For some time, its amount can be unchanged and remain at the same level. Then hCG falls, which will finally indicate that the pregnancy has died.

In other cases, the level of chorionic gonadotropin begins to decrease immediately, on the first day after the end of the ovum.

It is characteristic that, unlike an ectopic pregnancy, a frozen pregnancy may have absolutely no signs. A woman may not have bleeding and pain, even all signs of pregnancy (toxicosis, breast tenderness) may still persist. It so happens that for two or three weeks she may not even know that the pregnancy has died. It is in these cases that the monitoring of the dynamics of the blood test for hCG will be able to diagnose the state of the embryo, and by the weeks of pregnancy, when decoding the data, it will become clear whether the embryo is alive or died.
