Progesterone injections to stimulate menstruation. On what day of the menstrual cycle is it better for a girl to take an analysis for progesterone

Almost always, when there is suspicion of hormonal disbalance, on failure menstrual cycle women should donate progesterone, when to donate, which day of the cycle is the most FAQ. Or another option, when you have to take a blood test for progesterone, if there are problems with conception, pregnancy (during gestation).

Adolescents tend to be more likely to become pregnant in the first six months of intercourse than adult women due to a lack of information and access to contraceptives, and a lack of planning for their sex life, which occurs at irregular intervals. Usually friends or relatives are those who indicate the methods of contraception used at the beginning, including efficient search medical consultations, gynecological examination and guidance on contraception.

How to force teenagers to use any method of contraception? What best method contraception? What is the most effective and with few side effects? How to avoid unplanned pregnancy and reduce the pregnancy rate in adolescence in Brazil?

1 Preparations

The doctor should prescribe the delivery of this analysis after observations and consultations. Especially if we are talking about a pregnant woman. Control and interpretation of the results should be carried out by a specialist, since there is whole line moments that are difficult to deal with common man. So, many women do not know or quite often forget that the parameter of the ratio of LH to FSH in girls before the first menstruation is stably equal to 1. During the year from the first menstruation - from 1 to 1.5, and after 2 years (when menstruation ), this figure ranges from 1.5-2. To avoid mistakes, you should not self-medicate. Below, we will consider when and how a woman gives up correctly and how it is deciphered.

To prevent pregnancy, it is necessary to interrupt or avoid the process of ovulation, fertilization or implantation of an egg in the endometrium. Various Methods contraception will work in one of these phases, which has specific characteristics, some of which are recommended or even prohibited for adolescents.

The ideal method of contraception should be easy to use, 100% effective, zero risk and no side effects. Unfortunately, there is no method that regulates all these qualities. In adolescence, the association of methods is indicated in an attempt to increase the prevention of unintended pregnancy and reduce side effects. The most commonly used combination is combined oral contraceptive and hormonal contraceptive.

For analysis to show correct results, it is necessary to carefully prepare for the delivery. First of all, you should know that a number of changes hormonal background possible not due to any serious illnesses, but because of stressful situations, especially if a woman constantly experiences nervous tension.

So, if a woman's body is in stressful situation, there may be a significant increase in the amount of LH and cortisol. Especially if the stress is chronic. This does not allow you to get an objective picture of the state of the hormonal background, which does not make it possible to accurately determine the state of a woman's health.

Health professionals working with adolescents need to be knowledgeable about the various available methods and know which are most commonly used in this age group. These methods can be divided into behavioral, barrier, hormonal, intrauterine, and surgical devices.

When deciding on a contraceptive method, consider the following aspects. Knowledge of the specific features of adolescence, the social and familiar context of the adolescent. Proper guidance and transfer of information about the method for a complete understanding of the teenager.

Next, it should be said about how blood donation should take place. It usually takes place on days 5-7 of the cycle. During these days, you can get the optimal quantitative indicators of the hormones LH, estradiol, FSH, prolactin, testosterone, etc. Donate blood for progesterone only after the onset of the second phase of the menstrual cycle, and it is recommended to do this approximately in the middle of this phase.

Follow-up and continuation of medical and gynecological care when using a contraceptive method. None of these are listed for this age range as the rejection index is high. They need self-control and knowledge own body. They should be discouraged, but it is important that they be used correctly. The table should be taught in such a way that at least adolescents avoided sexual intercourse during the period of the highest birth rate. In practice, it is observed that most insecure relationships occur during this period, when the libido is greater.

2 Indicators of norm and deviation

At the end of the ovulatory processes, when the release of the egg from the follicle and the formation of the corpus luteum (the gland that secretes progesterone) are over, progesterone is taken. It is also called the pregnancy hormone. has a rather limited lifespan (3-4 months), during which hormone synthesis is performed. After this, the formation of the placenta occurs, which begins the generation of hormones in required quantities. In the absence of a fetus, the death of the corpus luteum occurs after 1-2 weeks, after which the processes of menstruation begin.

The same thing happens with coitus interruptus: when they are discouraged, they do not use any protection. The Billings method, which is based on changes in cervical mucus during the fertile period, and the synthothermic method, which requires daily measurements of basal body temperature, which fluctuates during ovulation, are contraindicated in adolescents due to their degree of difficulty. Known as the desktop method, it is based on the calculation of fertile days during the ovulation period, which occur in the middle of the menstrual cycle, usually from the 12th or 14th day of the cycle.

For the treatment and prevention of problems with the menstrual cycle (amenorrhea, dysmenorrhea, menorrhagia, Opsomenorrhea, etc.) and vaginal dysbiosis, our readers successfully use a simple advice of the chief gynecologist Leyla Adamova. Having carefully studied this method, we decided to offer it to your attention.

Progesterone, when taken, is needed for preliminary assessments of ovulation and the quality and life span of the corpus luteum. In the case of normal menstruation (when its cycle is regular and is 28-30 days), this analysis must be taken only when the middle of the second phase of the menstrual cycle comes. Another option is with regular measurements of basal body temperature after 5-7 days have passed since its increase. If the cycle is irregular, the analysis may be retaken several times.

In general, the fertile period is around day 14 in women who menstruate every 28 days. Unfortunately, ovulation is not precise and depends on various emotional and nutritional factors. So it's hard to predict right time ovulation. Average duration The life of an egg is 24 hours, and that of a sperm is about 48 hours.

In adolescence, this method does not work because the adolescent usually does not remember the day she menstruated or did not count. right days after menstruation, and it is difficult to accurately calculate the period of fruiting. In addition, dating is sporadic and often unexpected. Only very motivated teenager who is organized and aware of his bodily habits and records the days of the menstrual cycle will have a chance to succeed in the council. You also need a partner who respects your decision and doesn't demand a relationship during the fruiting season.


The main sign of normal ovulatory processes and the formation of corpus luteum is an increase in the amount of progesterone by an order of magnitude (10 times). In addition to the yellow bodies in the normal state of the body, it is generated by the adrenal glands, like other reproductive hormones.

The chart can be used in conjunction with condoms and while there is still a risk of failure, these are negligible. This is not a contraceptive method, but common sexual behavior among adolescents who are starting their sex life. It consists of removing the penis from inside the vagina before ejaculation begins. Low efficiency and high risk! This requires a lot of self-control and discipline on the part of the man, and besides, the secretion that precedes ejaculation may already contain sperm, hence the possibility of pregnancy.

Coitus interruptus is a predisposing factor premature ejaculation and impotence in men. In women, it disrupts or prevents orgasm. It is important to remember that even if there is no complete penetration, pregnancy can occur, especially if the teenager is in fertile time. For these reasons, this method is not reliable in practice and should always be contraindicated in adolescence.


  1. Peculiarity female body, in which there is an increased synthesis of sex hormone in the adrenal gland (with hyperplasia of the adrenal cortex).
  2. In the case of a cyst in the corpus luteum.
  3. During pregnancy.
  4. With blistering.

The reasons for the decrease in the concentration and amount of this hormone below the average norm:

The male condom, also called a condom, consists of a lithium sheath that covers the pelvis during intercourse and stores semen through ejaculation, preventing it from entering the cervical canal. The method is considered low cost with no side effects and does not require medical supervision. In advice on its use, it is important to teach how to put it on and take it off. The condom should be placed before penetration, with a straight pelvis. The container at the end of the condom should be tightened during placement to remove air from the inside and help deploy it to the base of the penis.

  1. Ovulation does not occur.
  2. Various problems of the corpus luteum.
  3. Probability of miscarriage.

3 Thyroid-stimulating hormones

TSH: This is the abbreviation for thyroid-stimulating hormones. This type pituitary hormone controls the functioning of the thyroid gland. This hormone is responsible for the synthesis of thyroid hormones, their quantity and quality, which has significant influence on its production (on the principle of feedback).

Withdrawal of the condom should take place after ejaculation, with the penis still erect, providing a base for it, so there is no leakage. The condom cannot be reused. Despite the widespread use of the method among teenagers, what happens in practice is abuse, especially in the earliest centuries. Factors that contribute to this fact are associated with the shortcomings of the method, such as the need for manipulation during intercourse, high motivation, knowledge and ability to use, self-confidence and interaction between spouses.

Girls and women have a concentration of this hormone in the blood plasma greater than that of males, by about 1/5. It should be noted that during adulthood, quantitative TSH indicators increase significantly. At the same time, the synthesis of TSH significantly changes from the average values ​​throughout the day. So, the maximum is reached at about 2-4 am, for the morning time the peak falls at about 6 am, and the absolute minimum is fixed from about 3-6 pm. Recent studies have established that the amount and concentration of TSH can vary depending on the time of year. So, peak values ​​appear in December.

Its placement is more complex than that of a condom, requiring advanced training. It consists of a thin transparent tube with a ring at each end, one open and one closed. The closed ring should be inserted into the vagina while the open ring remains outside the insert, protecting the vagina and the base of the penis during intercourse. In addition to being more expensive than the male condom, it needs more motivation and guidance as it comes with aesthetic and manipulation issues.

It should be used by women with more responsibility, usually in their late teens. This is a latex device that is inserted into the vagina before intercourse, with spermicidal gel, and acts like a cervical canal cap to prevent sperm from entering the vagina. To increase its effectiveness, it must be linked to the table, in addition to being withdrawn eight to ten hours after intercourse. You need a gynecological exam to determine suitable size and teach him how to place it.

With an increase in this parameter, hypothyroidism is possible (primary, which are caused by thyroid insufficiency), various tumors (including malignant ones). Its increase can sometimes signal a danger to the fetus (if the woman is pregnant).

At reduced content TSH in the blood is often marked by hyperthyroidism (primary, which are associated with dysfunction of the thyroid gland), a decrease in the functions of the pituitary gland, and the influence of various drugs that treat the thyroid gland is possible.

Pregnancy, miscarriage, or weight gain require further evaluation. Hormonal methods are available at various forms representations, combinations and therapeutic schemes. They are considered the most effective methods contraception. Birth control pills, one of the drugs most studied in medical therapy, with correct use is reversible, effective and safe method, which is the most popular form of contraception known throughout the world, including adolescents. However, it is in this age group that the greatest likelihood of abuse and rejection occurs.

4 Parameters of thyroxine

Thyroxine is one of the most important thyroid hormones. It is responsible for the regulation of metabolism, energy metabolism, for the processes of protein synthesis, oxygen metabolism, etc. This hormone is necessary for the synthesis of TSH and progesterone, while he himself carries out their suppression. If during the test it is planned to analyze not only progesterone, but also thyroxine, it is necessary to refuse food intake and preparations containing iodine (for example, seaweed).

The most commonly used estrogen is ethinyl estradiol. The so-called low dose tablets contain amounts of less than 50 μg. Progestogens are needed to provide greater consistency with estrogenic contraception and to improve menstrual cycle control.

The mechanism of action consists of: inhibition of the peak of luteinizing hormone in the middle of the cycle, preventing ovulation; thickening of the cervical mucosa, difficulty in sperm migration; reduction of glandular glycogen production in the endometrium, which makes pregnancy difficult; change in tubal contractility.


For healthy adult woman the level of this hormone decreases with aging (after 40 years), while the concentration and amount of this hormone in women is lower than in men. The quantitative and qualitative maximum of this hormone occurs approximately in the 3rd trimester of pregnancy. During pregnancy, a change in the quantitative indicators of this hormone can signal a number of dangers to the fetus. At the same time, for non-pregnant women, the daily maximum of thyroxin occurs in the morning, from about 8 am to noon, and the minimum is at midnight.

Side effects on organs and metabolism are related to hormonal dosage, time of use and individual predisposing factors. Knowing these effects is of fundamental importance, since they constitute one of the main limiting and adaptive factors to the method.

The most common symptoms are: estrogens - dizziness, nausea, vomiting, dizziness, irritability and mastalgia; progesterone - increased appetite, intermediate bleeding, hair loss, changes in libido. In adolescents, weight gain and interstitial hemorrhages are factors that contribute to misuse or abandonment of the method, and it is important to note that these symptoms are passive and tend to decrease with regular use.

5 Follicle-stimulating hormone

This hormone regulates the functioning of sexual functions. This hormone is synthesized in girls cyclically - depending on the phase of the menstrual cycles. It is responsible for the appearance and maturation of germ cells in both men and women. In the female, the egg in the ovaries is formed as part of a follicle, which consists of individual (follicular) cells. It is these cells that synthesize a number of female sex hormones that are responsible for the formation of the corpus luteum (and, accordingly, for the production of progesterone).

Smaller pills and progestogens with lower androgenic, mineralocorticoid, and anabolic effects should be chosen as a way to avoid these symptoms. How the pill is used is the cause of teenage debt. The first card can be started on the first or second day of the cycle. Output intervals up to 12 hours have no effect; long intervals can lead to blood loss and ovulation, especially if they occur in the first seven doses, and a condom should be used as a safety method.

The amount of FSH in a woman is accompanied by a level of rise in luteal hormones. At the same time, at the peak of LH, a significant decrease in FSH is observed. So, the level of FSH increases significantly in the postmenopausal period, and during pregnancy there is a significant decrease in this hormone (while it is sometimes almost impossible to determine its amount).

At the same time, physical activity, diet, obesity, operations, etc. have a significant effect on the hormone index.

A change in the amount of FSH may indicate various reasons. Thus, an increase in the amount of this hormone is possible due to the insufficiency of the functions of the genital organs, both due to genetic changes and autoimmune ones. Sterilization by any method, alcoholism, orchitis, menopause - all this increases FSH levels. Pituitary tumors, both benign and malignant, also affect the increase.

A decrease in the amount of the hormone is possible due to the hypofunction of the pituitary gland, sometimes with disorders of the hypothalamus, during pregnancy.

IN this material the main hormones were listed, which should be paid attention to when deciphering the analysis. They are especially important if a woman is planning a pregnancy. For an accurate decoding, you need to contact a specialist who will also prescribe means to restore the hormonal background, which can save the pregnancy.

And some secrets...

Have you ever experienced problems with menstrual cycle? Judging by the fact that you are reading this article, the victory was not on your side. And of course, you know firsthand what it is:

  • copious or scanty discharge with clots
  • chest and lower back pain
  • pain during sex
  • bad smell
  • discomfort when urinating

Now answer the question: does it suit you? Can problems be tolerated? And how much money have you already "leaked" for ineffective treatment? That's right - it's time to end this! Do you agree? That is why we decided to publish an interview with the chief gynecologist of Russia, Leyla Adamova, in which she revealed a simple secret to normalizing the menstrual cycle. Read article…

A blood test for progesterone is included in the list of required studies at the period of pregnancy planning, at early dates bearing a child or in the presence of any problems of a gynecological nature.

The slightest deviation from the norm indicates the presence serious violations for which appropriate action must be taken. Otherwise, it is possible to develop negative consequences for a woman's body, especially if she plans to have a child.

Progesterone - what is this hormone?

Progesterone is extremely important hormone in a woman's body. It is produced by the adrenal cortex and corpus luteum. It appears at the site of the dominant follicle after ovulation. If a mature egg is not fertilized, then corpus luteum dies and menstruation begins. When everything happens the other way around, the concentration of progesterone increases every day. The corpus luteum produces this hormone until approximately the 16th week of pregnancy, after which the placenta takes over this function.


It is thanks to the action of progesterone on the body of a woman that attachment and successful development fertilized egg. It leads to a thickening of the inner layer of the uterus, which is an ideal environment for the development of the embryo. This hormone significantly reduces the contractility of smooth muscles. This reduces the risk of spontaneous abortion because the uterus is unable to reject the implanted egg. Also, progesterone has a beneficial effect on the mammary glands of a woman, which allows them to prepare them for the lactation period.

How does the level of progesterone change during the menstrual cycle?

The level of progesterone in a woman's body is unstable. It changes depending on the phase of the menstrual cycle. In the first days after the onset of menstruation, the concentration of this hormone is minimal. In the future, it begins to grow during the onset of ovulation and for some time. If pregnancy does not occur, there is a sharp decrease in the level of progesterone, which ends with the next menstruation. When fertilization has occurred, the concentration of this hormone begins to increase further.

Based on this, the following progesterone norms are distinguished depending on the phase of the menstrual cycle (nmol / l):

  • in the period before the onset of ovulation, the norm is 0.31-2.25;
  • during ovulation, the progesterone level can be 0.47-9.42;
  • during the functioning of the corpus luteum, the concentration of the hormone reaches 6.98-56.52.


Why might you need an analysis to determine the level of progesterone?

At healthy woman From the moment of ovulation to the onset of menstruation, at least 10 days pass. Throughout this period, the corpus luteum in in large numbers produces progesterone, which allows it to properly prepare a woman's body for bearing a child. If the second phase of the menstrual cycle is significantly shortened, the endometrium is not able to go through all the changes that ensure a successful pregnancy. This condition can also lead to spontaneous abortion at an early date.

Timely detection of such violations will allow you to save the pregnancy. Therefore, testing for progesterone is mandatory if a woman is planning or has already conceived a child. Referral for laboratory diagnostics of this type receive in other cases:

  • when it is necessary to establish the cause of infertility with preserved ovulation;
  • in the case of induced ovulation in order to monitor the condition of the woman;
  • in case of development of menstrual irregularities, especially if they are present for a long period;
  • if a woman has many unpleasant symptoms, which may indicate diseases of a gynecological nature, as part of complex diagnostics state of the body.

How to get tested for progesterone?

How to take an analysis for progesterone so that it is as truthful as possible? There are a few simple rules for this:

  • An analysis for progesterone during pregnancy or at any other time should be taken exclusively on an empty stomach in the morning.
  • If it is not possible to visit the laboratory on time and the procedure is postponed closer to lunch, it is allowed light breakfast. The main condition is that at least 6 hours must pass from the last meal.
  • Before the test, you are allowed to drink plain water, but it is recommended to exclude any other drinks.
  • Day before the event laboratory research blood, it is necessary to abandon fatty foods that can distort the result by increasing cholesterol levels.
  • The day before the test, it is recommended to exclude alcohol, coffee, tea and any spicy food from the diet.
  • For a few days, it is advisable to stop taking any medication. If this is not possible, it is necessary to notify the laboratory assistant about the time and amount of drugs used.
  • The day before the test, you need to abandon excessive physical activity and avoid stressful situations.
  • Smoking is strictly prohibited 2 hours before visiting the laboratory.


On what day of the cycle do they take progesterone to get reliable result analysis? If a woman's menstruation occurs regularly, and the cycle lasts about 28 days, it is recommended to conduct a blood test to determine the level of this hormone in the period from 22 days after next menstruation. At the same time, it is necessary to visit the laboratory no later than a week before the next bleeding. Especially this rule useful for women who have a much longer cycle.

When to take progesterone if periods are irregular? IN this case the doctor gives several directions to the laboratory for different days. This allows you to analyze the level of progesterone in dynamics, which will display a complete picture of the state of the woman's body. In order not to take expensive tests several times and quickly get all necessary information, you can pre-determine the day of ovulation. After its onset, after about 7-8 days, you can conduct a blood test for progesterone levels.

You can determine the moment of ovulation with the help of transvaginal ultrasound. With its help, it is easy to obtain information about whether a dominant follicle develops in the ovary, whether a corpus luteum has appeared.

You can also establish the fact of the onset of ovulation at home. To do this, you must use a conventional thermometer, with which you need to measure daily basal body temperature. As soon as it begins to change, we can talk about the onset of ovulation. The main thing is to carry out the temperature measurement procedure in the morning without getting out of bed. If this method of determining ovulation is difficult, you can purchase regular test strips at the pharmacy.


What do deviations from the norm indicate?

If, for example, in the Invitro laboratory, progesterone is detected in a concentration that differs from the norm in any direction, we can talk about the presence of certain diseases. Based on additional test results, the doctor makes a diagnosis and prescribes the appropriate treatment. Most often, this is done by a gynecologist-endocrinologist who has the necessary qualifications. If hormonal disorder detected in a pregnant woman, then the treatment is prescribed by her district doctor.

Exceeding the level of progesterone indicates such pathological conditions:

  • the presence of amenorrhea and other diseases that could lead to it;
  • development of cysts of the corpus luteum;
  • the presence of bleeding in the uterus;
  • pathology of the placenta, which adversely affect the development of the fetus.

A decrease in the level of progesterone is observed in the presence of the following pathologies:

  • the presence of chronic inflammatory processes in the ovaries;
  • irregular periods;
  • the presence of various disorders in the functioning of the corpus luteum;
  • pathologies of fetal development, which can result in spontaneous abortion;
  • lack of ovulation, which leads to infertility.

Collection components render complex impact on endocrine system contribute to the normalization of hormonal levels.

How to bring the level of progesterone back to normal?

If, after testing, it is revealed reduced level progesterone, appropriate treatment is prescribed. There are several ways to normalize the concentration of this hormone. In some cases, progesterone is prescribed in the form of a solution of different concentrations - 1%, 2%, 2.5%. It is administered subcutaneously or intramuscularly.

Progesterone injections are made strictly according to the doctor's instructions. They are prescribed in the second half of the cycle for several days. You can not abruptly interrupt treatment, exceed or lower the dosage of the drug, which can lead to hormonal failure in a woman's body.

Also, progesterone is often prescribed in the form of tablets. The most popular drugs from this group are Duphaston, Utrozhestan. In this case, the first means is made from synthetic components, and the second - from natural. Duphaston is taken orally only. This is a drug that has many positive reviews due to the almost complete absence of side effects. Utrozhestan can be taken in two ways - vaginally or orally.
