Ovulation after hCG 5000. Effect of hCG injection on the follicle

The hCG hormone plays an important role in the human body. 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, so gynecologists in such cases prescribe an injection of hCG.

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

There are many drugs containing hCG or its synthetic analogues, for example, Humegon, Pregnil, Ovitrelle. Doctors sometimes prescribe additional drugs for the treatment of infertility: Diferelin, Luveris, Duphaston, etc.

Release form and composition of chorionic gonadotropin

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

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 vary slightly, all this is indicated in the package leaflet, the price may also differ. Store the drug in a cool place without direct sunlight.

Gonadotropin shot

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

Purpose and indications for hCG injections

The drug is prescribed for the treatment of infertility in women and men, as well as to maintain the natural level of the hormone in the body during pregnancy. Depending on the purpose, the injection scheme 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.
  • Reducing the risk of cyst growth. The hormone prevents the follicle from shrinking and forming a benign tumor inside the ovaries. Normally, the follicle bursts, and the cyst does not develop.
  • Maintenance of the corpus luteum at the initial stage of pregnancy. Due to hormonal imbalance, it can flake off and provoke a miscarriage.
  • Conducting artificial insemination and preparing the reproductive system of a woman for the transfer of embryos into the uterine cavity. In the process of such ovulation, not one follicle is obtained, but several at once.
  • Exclusion of the risk of miscarriage at an early stage, if there was already a negative experience earlier.
  • Presence of hydatidiform mole 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 when stimulating ovulation is used if it cannot pass naturally. The causes of the problem are different, but the most common are tumor formations, medication that suppresses reproductive function, and polycystic ovaries. Injections are prescribed only on the basis of deciphering the data obtained from the results of tests for the level of hormones in the body.

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

Hormone treatment begins from the first day of menstruation, and if the cycle is knocked down, then from the first expected 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, you can not drink alcohol, drugs, it is not recommended to smoke. 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 worries. It is recommended to avoid sex during this period. Sexual intercourse will be effective only 5 days after ovulation.

When is testing done after an hCG injection?

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

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

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

Every day after diagnosing the growth of the follicle using ultrasound. This option is appropriate if there are long delays and breaks in 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, chorionic gonadotropin injections have some contraindications. They are more associated with tumor neoplasms, as well as some individual characteristics of the organism.

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 recommended to use gonadotropin for 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 genital organs of the child may appear. If there is suspicion or an established diagnosis of obstruction of the fallopian tubes, the doctor does not prescribe hCG injections. Do not use the drug for thrombophlebitis and chronic inflammatory processes in the adrenal glands.

Instructions for use

Regardless of the diagnosis, gonadotropin is prescribed intramuscularly. When planning pregnancy before using the drug, it is recommended to undergo a complete examination. When stimulating the ovulation process, one-time injections are used with a dosage of 5000 to 10000 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 using gonadotropin injections. For this, 10,000 IU are administered once. After 34-36 hours, the eggs are removed for their further fertilization. This is done in the case when a woman cannot become pregnant on her own. If there is a possibility of spontaneous abortion, and symptoms appear no later than 8 weeks, the woman is injected with 10,000 IU on the first day and then 2 times a week for 5000 IU. Therapy continues 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 a subsequent one, the same dosage is prescribed as a prevention of miscarriage as in case of a threatened miscarriage.

When diagnosing delayed sexual development, boys are prescribed from 3000 to 5000 IU once every 7 days. The duration of the course is at least 3 months, after which, if necessary, 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 normohormonal 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 units of the hormone are injected every 5 days for 3 months.


Gonadotropin preparations may 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. At this time, the chest and lower abdomen may also hurt. In case of 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 at a dosage of 500–1000 units 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 of age and adults, this dosage increases to 1500 IU.

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 otherwise.

Most often, hCG is needed if an athlete starts taking Trenbolone, a very strong steroid for gaining muscle mass. Previously, it was used only in veterinary medicine. PCT (post cycle therapy) in this case is a prerequisite for maintaining the reproductive function of the genital organs.

With 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 excess dosage also has negative consequences. It causes a sharp decrease in the number of active viable spermatozoa in semen.

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

Ovulation after an hCG injection occurs at different times, depending on the diagnosis and the medication itself. The injection is divided into several types, namely hCG: 1500, 3000, 5000, 6000, 7000, 10000. This article tells how long it takes after an injection of hCG for ovulation to occur.

Different Types of Ovulation Stimulation Schemes

First of all, the doctor conducts an examination of the couple. After establishing the diagnosis, the physician determines the treatment regimen, which provides for the duration of the course of treatment, the complex of drugs, the dosage and the type of the drug itself.

Usually an injection of hCG (Chorionic Gonadotropin) is prescribed if a woman has such correspondences:

  • age up to 35 years;
  • FSH levels are within normal limits;
  • good spermogram of the husband;
  • lack of ineffective long-term infertility treatment under the IVF program;
  • normal patency of the pipes.

As problems are identified, the doctor selects a drug with a certain level of hCG content. Among these funds may be: Horagon, Pregnil, Profazi, Ovitrel.

Numerous options are offered among the schemes:

  • a single injection of Chorionic Gonadotropin 5000 or 10000. Usually, after 24-36 hours, the corpus luteum reaches the desired size;
  • to stimulate the corpus luteum, a drug of 1500 or 5000 is prescribed. It is possible that the waiting time may be delayed.

There are also hCG regimens for boys before puberty and men.

How long to wait before ovulation after an injection?

Usually, the maturation of the egg occurs 36 hours after the injection. But the fact that a girl is able to get pregnant naturally after treatment is not a fact. It is possible that for fertilization she will need help, or rather, such procedures as IVF and IUI.

In addition to the above, the stimulant drug implies a number of drug additions after treatment. HCG injections change the hormonal background of a woman. To achieve stabilization at the end of the Chorionic Gonadotropin injection, the doctor prescribes medications: Utrozhestan or Duphaston, or Iprozhin.

Can there be no ovulation at all after treatment?

For some women, the injection does not really help even after long-term treatment. In such situations, the doctor determines a different course for the girl according to the examination.

As already mentioned, egg maturation occurs 36 hours after vaccination. And do not despair if the result is a little delayed. It is possible that the effect will manifest itself in a few days or weeks.

How long does it take to have sex in order for the egg to be fertilized?

If everything is in order with the husband's sperm, then daily sex is recommended for 3 days after the injection. For problems with sperm, sex is productive on the day of the injection and every other day.

As a rule, doctors advise experimenting with conception every other day.

When can you do a test?

Tests are usually carried out 3 days after vaccination. In most cases, ovulation occurs during this period.

No matter what the test or ultrasound shows, do not despair. Previously, women waited for years for a pregnancy that never happened. Today, medicine is growing every day. And, it seems, has already reached its peak. And at times she, truly, creates a diva. 1 - 2 unsuccessful attempts - this is not a reason for frustration. Pregnancy does not always happen when you most expect it. The main thing is to believe - and this faith will certainly justify itself.

What is the purpose of doing it? The specialist recommends an injection designed to stimulate ovulation when a woman has problems with the maturation of eggs. For each patient, the selection takes place individually, at the moment when the cause of such a condition is established, after passing all laboratory tests and undergoing a mandatory diagnostic examination.

After an HCG injection? What is the purpose of doing it? The specialist recommends an injection designed to stimulate ovulation when a woman has problems with the maturation of eggs. For each patient, the selection takes place individually, at the moment when the cause of such a condition is established, after passing all laboratory tests and undergoing a mandatory diagnostic examination.

Why do you need an hCG injection?

The main methods that help to establish the reason why the eggs do not mature in the ovaries are:

  • hormone analysis;
  • undergoing a permanent ultrasound examination;
  • it is necessary to carry out diagnostics for several cycles in a row in order to correctly draw conclusions regarding the condition of a woman, and then prescribe treatment.

The main factor that affects a woman's ability to become pregnant and bear a child is the process of ovulation. This is the period when the egg gets the opportunity to leave the shell and, having passed through the fallopian tube, be fertilized. Pregnancy will not occur if the egg has not been able to break through the follicle shell and exit it. A hormone called human gonadotropin is responsible for this.

Its function is to influence the corpus luteum and do this until the fertilized egg attaches to the uterine cavity. Further, the production of hormones occurs already in the placenta, which is responsible for supplying progesterone and estrogen to the woman's body. Quite often, ovulation, as well as the production of hormones, does not occur. Therefore, the doctor prescribes an injection of hCG, which is very important in the first trimester of pregnancy.

There are different doses of the hCG drug, which are selected individually for each patient.

For injection, different drugs are prescribed, which are selected specifically for each woman, depending on the existing indications. Before the procedure, patients are interested in questions about how long ovulation can occur after an hCG injection and how quickly the amount of hormones will increase after administration.

Doctors note that women, by determining whether ovulation occurs or not, and doing the test almost immediately (more often on the second or third day), get positive results. But this does not indicate that ovulation is observed. Therefore, for the reliability of the result, the test is recommended only on the third day after the administration of the hormone.

After the hCG injection, it is worth waiting for the moment when ovulation occurs, as well as an increase in the amount of the desired substance in the woman's body. Doubling can occur 1 time in 3 days. A very high level of progression is noted in the first trimester, which contributes to increased production of estrogen and progesterone.

An injection of hCG after ovulation must be monitored in order to properly monitor the growth of hormones. Such monitoring should be done both with the help of special tests and ultrasound. With an ectopic pregnancy, human gonadropin is also able to manifest itself, but at the same time it has other indicators and behavioral tendencies.

It is also worth remembering that the results of an hCG injection can be very different, for example:

  • the onset of ovulation in 24-36 hours;
  • perhaps a little later;
  • won't come at all.

Indications and contraindications

Indications for injection are factors such as:

  1. The need to stimulate the ovule.
  2. To prevent the reduction of the follicle in the event that the egg has left it. Otherwise, the shell may shrink and a cyst appears in its place.
  3. It is necessary to preserve the vital activity of the corpus luteum. To support it, you need to make an appropriate injection.
  4. If there is a slow development of the placenta, it does not form and does not release the right amount of hormones.
  5. To maintain pregnancy and avoid miscarriages.
  6. Before in vitro fertilization.

Contraindications for hCG injections include:

  • oncological disease, especially a malignant tumor of the ovaries;
  • pituitary tumor;
  • early menopause;
  • breastfeeding;
  • blood clots in the vessels or a genetic predisposition to this;
  • uterine tubal obstruction;
  • hypothyroidism, that is, a prolonged lack of hormones in the thyroid gland;
  • individual intolerance to the components of the drug.

Time of onset of ovulation after injection

Which drug to choose, the doctor decides. These can be the following types of medicines that contain human chorionic gonadotropin:

  • Clomiphene;
  • menopausal hCG;
  • recombinant p-follicle-stimulating hormone;
  • Humegon;
  • Pergonal;
  • Menogon.

In order to determine which drug a woman needs, the gynecologist must carefully examine the tests for the level of estradiol and luteinizing hormone.

An injection is prescribed only on the third or fifth day of the menstrual cycle, the initial dosage of the drug is chosen depending on the hormonal parameters. It is impossible to independently determine the volume of the drug, it is used only after the appointment of a regimen by a doctor. Usually they give an injection of hCG 5000 or 10000 units, which depends on the parameters of the woman's body.

Stimulation is carried out in cycles, under the careful supervision of a gynecologist, with the measurement of basal temperature. After the first stimulation with an injection, on the 5th (maximum 7) day, you need to undergo a control ultrasound examination. Its essence is to determine the cervical number, the amount of estradiol, the growth of the endometrium.

If there is no reaction, then the dose can be increased and the change in indicators will be monitored by ultrasound after 1 day. Folliculogenesis is considered dynamic if the follicle increases in size by 2 mm during the day, and the amount of cervical number - by 2 units. in 24 hours. If so, then the dose of the drug does not change. Its amount can be reduced by one ampoule when the rates increase very quickly.

Folliculogenesis - the active phase - lasts for 5 days and may end on the tenth or twelfth day after ovulation stimulation has begun.

When the shell has 18-20 mm, which is detected during the control examination, then ultrasound should be performed every day. In this case, the dose of the hormone is again reduced so that the follicle does not demonstrate independent behavior. When the number becomes 12 units, then the injections are stopped, and the last injection is given a day later - an ovulatory dose of human chorionic gonadotropin. A control measurement is taken 2-3 days later to confirm ovulation.

The hCG hormone plays an important role in the human body. 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, so gynecologists in such cases prescribe an injection of hCG.

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

There are many drugs containing hCG or its synthetic analogues, for example, Humegon, Pregnil, Ovitrelle. Doctors sometimes prescribe additional drugs for the treatment of infertility: Diferelin, Luveris, Duphaston, etc.

Release form and composition of chorionic gonadotropin

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

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 vary slightly, all this is indicated in the package leaflet, the price may also differ. Store the drug in a cool place without direct sunlight.

Gonadotropin shot

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

Purpose and indications for hCG injections

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

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

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, you can not drink alcohol, drugs, it is not recommended to smoke. This can negatively affect the reproductive processes in the body.

When is testing done after an hCG injection?

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

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

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

Every day after diagnosing the growth of the follicle using ultrasound. This option is appropriate if there are long delays and breaks in 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, chorionic gonadotropin injections have some contraindications. They are more associated with tumor neoplasms, as well as some individual characteristics of the organism.

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 recommended to use gonadotropin for 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 genital organs of the child may appear. If there is suspicion or an established diagnosis of obstruction of the fallopian tubes, the doctor does not prescribe hCG injections. Do not use the drug for thrombophlebitis and chronic inflammatory processes in the adrenal glands.

Instructions for use

Regardless of the diagnosis, gonadotropin is prescribed intramuscularly. When planning pregnancy before using the drug, it is recommended to undergo a complete examination. When stimulating the ovulation process, one-time injections are used with a dosage of 5000 to 10000 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 using gonadotropin injections. For this, 10,000 IU are administered once. After 34-36 hours, the eggs are removed for their further fertilization. This is done in the case when a woman cannot become pregnant on her own. If there is a possibility of spontaneous abortion, and symptoms appear no later than 8 weeks, the woman is injected with 10,000 IU on the first day and then 2 times a week for 5000 IU. Therapy continues 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 a subsequent one, the same dosage is prescribed as a prevention of miscarriage as in case of a threatened miscarriage.

When diagnosing delayed sexual development, boys are prescribed from 3000 to 5000 IU once every 7 days. The duration of the course is at least 3 months, after which, if necessary, 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 normohormonal 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 units of the hormone are injected every 5 days for 3 months.


Gonadotropin preparations may 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. At this time, the chest and lower abdomen may also hurt. In case of 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 at a dosage of 500–1000 units 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 of age and adults, this dosage increases to 1500 IU.

An hCG injection is an injection of hormonal drugs such as Menogon, Horagon, Pregnil, Choriogonin and others. Their active ingredient is human chorionic gonadotropin (hCG), which helps restore ovulation.

An injection of hCG with the introduction of these hormonal drugs helps to stimulate the process of ovulation. These drugs enhance the hormonal activity of the corpus luteum through the administration of hCG. To stimulate ovulation, the dosage of the hCG hormone is 5000-10000 IU. If the doctor plans to keep the pregnancy, the dosage should be 1000-3000 IU. In each case, the dosage is selected individually, taking into account the concentration of hormones in the body, the size of the follicle, and so on.

HCG includes two subunits - alpha and beta. The beta subunit underlies the pregnancy test. Beta hCG in the first weeks of pregnancy begins to be produced in the female body, and at 7-11 weeks its concentration increases several thousand times.

The main factor affecting a woman's ability to become pregnant is ovulation. This is the process of the release of an egg from the ovary into the fallopian tube due to the rupture of a mature follicle for its further fertilization and transportation through the genital tract. Often there are situations when the rupture of the follicle does not occur.

The hormone gonadotropin is responsible for conception and the normal course of pregnancy. It stimulates ovulation in women and promotes the hormonal activity of the corpus luteum until the egg is attached to the uterus.

In cases where ovulation does not occur in the female body for any reason, hormonal stimulation is performed with an injection. This procedure is prescribed for women whose ovaries do not ripen full-fledged eggs.

Indications

The procedure is effective in eliminating the following conditions in a woman's body:

1. Dysmenorrhea - a pathological condition characterized by severe pain during menstruation. Other symptoms may also occur: dizziness, weakness, nausea, vomiting, bloating, fainting, and others. 2. Ovarian dysfunction. 3. Anovulatory infertility. 4. The threat of spontaneous miscarriage. 5. Deficiency of the corpus luteum. 6. Incorrect formation of the placenta. 7. The inability of the female body to bear the fetus. 8. Preparation for IVF.

This procedure can be used in assisted reproductive techniques as an additional tool.

Men are prescribed for:

1. Hypogenitalism - a significant decrease in the functions of the sex glands and their underdevelopment. 2. Pituitary dwarfism (dwarfism) - growth retardation and development. 3. Sexual infantilism - a delay in the development of the body, manifested in the underdevelopment of the organs of the reproductive system. 4. Genetic disorders.

Contraindications

The use of injections of chorionic gonadotropin is contraindicated in:

1. Early menopause. 2. During lactation. 3. When a tumor process occurs in the ovaries and pituitary gland. 4. Obstruction of the fallopian tubes. 5. Thrombophlebitis. 6. Hyperthyroidism. 7. Individual intolerance to the drug. 8. Diseases of the adrenal glands.

HCG injection for anovulation

The following factors can lead to anovulation:

  • dysfunction of the hypothalamus;
  • neoplasms of the pituitary gland;
  • stress;
  • violation of the blood supply to the brain;
  • inflammatory diseases of the reproductive system;
  • genital trauma;
  • premature menopause;
  • obesity;
  • anorexia;
  • liver disease;
  • disorders of the thyroid gland;
  • taking hormonal contraceptives;
  • some medicines.

Before proceeding with the stimulation of ovulation, it is necessary to establish the true reason for its absence. For this, patients are prescribed a series of tests, ultrasound. It is also necessary to regularly measure basal temperature. The results of the studies will make it possible to determine the need for the procedure. In some cases, normalizing, for example, the level of thyroid hormones can contribute to the natural process of restoring ovulation. It is necessary to conduct regular ultrasound in order to monitor the development of follicles.

The initial ultrasound is done 8-10 days after the end of menstruation. Then every 2-3 days until the fact of ovulation or the next menstruation is established. According to the results of the research, you can prescribe an injection of hCG, which stimulates the process of ovulation and prevents the formation of follicular cysts.

As a rule, after an injection, ovulation occurs within 24-36 hours. It is confirmed by ultrasound results. In some cases, ovulation may occur after a longer time or not at all.

After confirmation of ovulation, injections of utrogestan or progesterone are given, which contribute to the further "maintenance" of the corpus luteum.

When ovulation is stimulated, the doctor determines the frequency and timing of sexual intercourse and insemination based on spermogram indicators.

After an injection of hCG, a pregnancy test is carried out no earlier than two weeks after the onset of ovulation. Test results before the expiration of this period may give false positive results.

HCG injection during pregnancy

During pregnancy, this procedure is prescribed in cases of low levels of human chorionic gonadotropin in the body in order to further maintain pregnancy. Low concentration of the hormone may be due to early pregnancy. In this case, before prescribing an injection, the doctor directs the patient to re-test to confirm the low level of the hormone.

Pregnancy after an hCG injection

After the hCG injection has been performed, it is recommended to do a pregnancy test no earlier than two weeks later. If you take an analysis for hCG earlier than after 2 weeks, then its result may be false positive. Therefore, after an injection of hCG, the level of this hormone should be determined in dynamics. Starting from the moment of conception, the level of this hormonal substance increases by 2 times every few days. The maximum levels of hCG are detected at the end of the first trimester. After that, its level begins to gradually decrease.

If the indicator of the concentration of the hormone in the blood is 20% or more below normal, then this may indicate a number of serious disorders in the body:

  • chronic placental insufficiency - a violation of the function of the placenta, leading to insufficient oxygen supply to the fetus and a possible delay in its development;
  • ectopic pregnancy that develops outside the uterus - in the fallopian tube (99% of cases), abdominal cavity, ovaries. Such a pregnancy poses a great threat to a woman's life;
  • missed pregnancy - cessation of fetal development and its further death;
  • risk of miscarriage.

Side effects

Side effects may include:

  • ovarian hyperstimulation syndrome - a condition of the female body, characterized by an overly strong reaction of the ovaries to the drug;
  • hydrothorax - the process of accumulation of fluid in the pleural cavity;
  • ascites is a disease characterized by the accumulation of large volumes of fluid in the abdominal cavity;
  • thromboembolism is an acute blockage of a blood vessel by a thrombus that has broken away from its place of formation and subsequently entered the bloodstream. Such process often comes to an end with an ischemic heart attack;
  • cyst formation.

Procedure

There are standard dosages for injections of chorionic gonadotropin:

  • in order to stimulate ovulation, chorionic gonadotropin 5000 or 10000 IU is prescribed once;
  • in case of stimulation of the corpus luteum, chorionic gonadotropin 1500 or 5000 IU is used;
  • to stimulate superovulation during reproductive events, chorionic gonadotropin 10,000 IU is prescribed once. After 34-36 hours, the egg is taken;
  • in case of habitual miscarriage or the threat of miscarriage, a woman is prescribed an injection of hCG to maintain pregnancy, starting the course no later than the 8th week of pregnancy and continuing to administer until the 14th week inclusive. At the first injection, chorionic gonadotropin 10,000 IU is administered. Then continue injections of the drug twice a week at a dosage of 5000 IU;
  • this procedure gives good results in case of delayed puberty in boys. In the treatment, injections of chorionic gonadotropin are used at a dosage of 3000-5000 IU per week for three months;
  • with delayed sexual development in men, hCG injections are prescribed at a dosage of 500, 1000, 1500 and 2000 IU per day for 1.5-3 months;
  • with hypogonadotropic hypogonadism, chorionic gonadotropin 1500-6000 IU once a week in combination with menotropins is used as a treatment;
  • in the case of cryptorchidism, boys under 6 years of age are prescribed chorionic gonadotropin 500-1000 IU for six weeks, two injections per week. Children over 6 years of age are injected with the drug at a dosage of 1500 IU.

The drugs are administered to the patient intramuscularly. This procedure can be done in special medical institutions, or on your own if the woman has the skills to do intramuscular injections correctly. This need often arises in patients due to a long course of treatment.

The doctor determines the dose of the drug individually for each patient.

In the pharmacy you can find the drug in such dosages:

  • chorionic gonadotropin 500 units;
  • hCG 1000 units;
  • HCG 1500 units;
  • hCG 5000 units;
  • HCG 10000 units.

Release it in the form of a solution for injection.
