How much progesterone should a woman have? Blood test for progesterone - indications, preparation, standards and interpretation. What affects the level of progesterone in the blood? Pathological causes of increased progesterone in women

Progesterone is a hormone produced by the female sex glands, that is, the ovaries. Its importance for women's health is quite high. Based on the level of this component in the body, the doctor can assess the condition of the reproductive system.

Progesterone is produced from the beginning of the ovulation period until the 16th week of pregnancy. If fertilization of the egg does not occur, the hormone ceases to be produced and menstruation begins. But the effect of progesterone is not limited to this. Let's consider the main tasks of producing this substance:

  1. Normal progesterone levels in women are one of the main conditions for conception. It is with his assistance that the fertilized egg is implanted into the uterine wall.
  2. The hormone is responsible for the deposition of subcutaneous fat and stimulates the development of the skeleton and genitals. It is the product of the secretion of the corpus luteum and adrenal glands.
  3. It also helps reduce contractions of the uterine muscles, which helps avoid embryo rejection. For the same purpose, progesterone reduces a woman’s immune defense so that the body does not reject the foreign protein of the fetus.

Thus, insufficient levels of this hormone in the female body pose a certain danger, since in this case the likelihood of spontaneous abortion increases. Also, with such indicators, the uterus cannot be maintained in the condition required to bear a child.

To have a clearer idea of ​​the action of progesterone, you should familiarize yourself with the phases of the menstrual cycle:

  1. During the first phase, as a result of the work of pituitary hormones and estrogens, the egg matures, and the mucous membrane forms in the uterine cavity.
  2. During the second phase, progesterone stops the formation of the mucous membrane, after which the production of substances necessary to maintain pregnancy begins.
  3. If conception does not occur, at the end of the cycle the corpus luteum loses its ability to produce the hormone.

Changes in the concentration of the hormone progesterone in women

Hormonal levels are not at the same level and vary depending on menstruation. The highest content is observed during the period of ovulation. If fertilization has occurred, its level continues to increase, creating the required conditions for the development of the egg.

In the absence of conception, the hormone content declines and gradually reaches the level of the preovulatory phase. After this, menstruation begins. The most active activity of progesterone can be observed within 10 days after ovulation. During this period, it prepares the uterine endometrium for the placement of a fertilized egg.

Progesterone: normal in women

Female hormonal levels are influenced by various factors. This is pregnancy, the onset of menopause, taking hormonal medications. The hormone content is measured in ng/ml and nmol/l. When taking these factors into account, progesterone levels must meet certain standards. When taking contraceptives:

  • ovulation phase – 1.52-5.46;
  • follicular phase – 0.00-3.60;
  • postmenopause – 0.00-3.18;
  • luteal phase – 3.02-66.80.

During pregnancy:

  • first trimester – 29.60-105.60;
  • second trimester – 93.80-159.00;
  • third trimester – 264.60-508.80.

If a woman does not take contraceptives and is not pregnant, the indicators should be within the following standards:

  • during the follicular phase – 0.32-2.23;
  • during ovulation – 0.48-9.41;
  • during the luteal phase – 6.99-56.63;
  • during the postmenopausal period – 0.64.

During the follicular phase, after the onset of menstruation, hormone production is negligible. With the beginning of the ovulatory phase, approximately on the 15th day of the cycle, its concentration gradually increases. When the follicle ruptures and releases the egg, the luteal phase begins.

The corpus luteum forms from the follicle, which produces progesterone. The body receives a certain signal and begins to prepare for fertilization. At week 16, if pregnancy occurs, the placenta takes over the function of producing the hormone. The concentration during this period rapidly increases and exceeds the initial value by several hundred times.

Increased progesterone in women: causes

If the level of this hormone in the female body exceeds the norm, as a rule, this means pregnancy. Lack of conception with increased progesterone levels indicates the presence of certain health problems. It could be:

  • cycle irregularity;
  • bleeding;
  • kidney or adrenal diseases;
  • also a corpus luteum cyst.

If progesterone is elevated in a woman, the reasons may be abnormal development of the placenta during pregnancy.

Low progesterone in women

Hormone deficiency can cause miscarriage. The most dangerous period in this situation is the first trimester. After fertilization, with normal levels of this hormone in the female body, certain physiological processes must occur that contribute to the maintenance of pregnancy. If there is a lack of progesterone in a woman, a new cycle begins, and the fertilized egg is rejected.

Lack of progesterone in women is often a signal of certain abnormalities, namely:

  • hormonal imbalance and threat of miscarriage;
  • lack of ovulation process;
  • lack of activity of the placenta or corpus luteum;
  • post-term pregnancy;
  • pathologies in fetal development;
  • uterine bleeding;
  • the presence of inflammatory diseases in the female reproductive organs;
  • irregular periods.

If the concentration of progesterone is insufficient, medications containing this hormone are prescribed. These medications can be in tablet form or in the form of injections. After conducting the required tests, the doctor makes a decision as to which form of the drug will be most optimal for the patient. In most cases, injections are prescribed.

Injection solutions are divided into three types depending on the concentration of the hormone and can contain 1%, 2% and 2.5% progesterone. An auxiliary component in these preparations is almond or olive oil. The solution is injected under the patient's skin or intramuscularly. In this case, it affects the body faster than tablets, but the effect of taking it is more pronounced. These drugs increase progesterone in women and are prescribed for hormonal imbalance, delayed menstruation, or threatened miscarriage.

However, it should be remembered that taking these medications may have side effects, such as swelling, nausea, and increased blood pressure. For this reason, they should be prescribed with extreme caution in cases where a woman has the following abnormalities:

  • disorders of the kidneys;
  • diabetes;
  • epileptic seizures;
  • manifestations of migraine;
  • heart disease;
  • depressive states;
  • ectopic pregnancy;
  • bronchial asthma.

It is necessary to stop taking these medications if you have diseases such as breast tumors, liver problems, and vaginal bleeding.

Lack of progesterone in women: symptoms

When there is a deficiency of progesterone, the body signals through the following symptoms:

  1. A woman may experience chest pain or bloating.
  2. She may experience vaginal bleeding, menstrual irregularities, and sudden mood changes.

If you notice the above symptoms, you should seek advice from a medical institution. If progesterone is low in women during pregnancy, this can lead to spontaneous abortion. This situation is especially dangerous at week 20.

Procedure for taking tests

Each test must be taken at the appropriate time. This rule also applies to progesterone testing. The most suitable period is after the end of ovulation. To determine the right time as accurately as possible, you should use an ovulation test. It is worth considering the following features:

  1. If the cycle length corresponds to 28 days, the analysis is taken on the 22nd or 23rd day after the start of menstruation.
  2. If the cycle lasts 35 days, the hormone concentration should be determined on the 28th or 29th day.
  3. To avoid mistakes in taking tests, it is recommended to first consult a doctor regarding this issue.

A blood test for progesterone content has its own characteristics depending on the cycle:

  1. If your periods are regular, then the test should be taken 7 days before their start.
  2. In case of an irregular cycle, the study is carried out several times.
  3. Determining the right time is not difficult if a woman measures her basal temperature and makes a schedule. In this case, the analysis must be carried out on the 6th or 7th day after the increase in temperature.
  4. At least 6-8 hours should pass between eating and donating blood. It is better to carry out this procedure in the morning on an empty stomach.
  5. If during pregnancy a woman takes a test to determine the concentration of progesterone and at the same time takes any medications, she must inform the laboratory assistant about this so that he can make the appropriate notes. Otherwise, the results will be biased.

Conclusion

Thus, we examined the main subtleties regarding the production of progesterone: what it is in women, what norms are acceptable and what deviations indicate, etc. This hormone occupies an important place in the female body, in particular, in the reproductive system. Its production provides all the necessary conditions for conception and successful bearing of the baby. And a deficiency can cause the absence of necessary physiological processes, which will ultimately lead to termination of pregnancy.

Features of hormone production are presented in the video:

Progesterone is a hormone that belongs to the steroid group and is produced by the ovaries, adrenal glands and placenta.

Its main function is to ensure a healthy pregnancy. It also plays a significant role in metabolic processes.

Let's consider what the norm of progesterone is in women, and also find out what happens when its level fluctuates upward or downward.

During pregnancy

Progesterone is involved in regulating the functioning of the female reproductive system. Its active synthesis begins in the second half of the menstrual cycle. The mature egg leaves the follicle, and its place is taken by a temporary endocrine gland - the corpus luteum, which is responsible for the intensive production of the “pregnancy hormone”.

During this period, progesterone performs an important function - it ensures a change in the inner layer of the uterus, making it comfortable for implantation (attachment) of a fertilized egg and the development of the embryo. The hormone is responsible for the secretory phase of the endometrium, which is characterized by:

  • swelling of the mucous membrane;
  • accumulation of nutrients in cells, including glycogen;
  • increased vascular tortuosity and increased blood flow.

When pregnancy occurs before the 16th week, progesterone is secreted by the corpus luteum, then the placenta performs this task. Functions of the hormone during pregnancy:

  • accumulation of subcutaneous fat in a woman - this creates a supply of nutrients;
  • enlargement of the uterus and relaxation of its muscles to prevent spontaneous contractions;
  • proliferation of the lobes of the mammary glands responsible for lactation;
  • suppression of milk production until birth;
  • participation in the genesis of certain fetal tissues;
  • relaxation of muscles and ligaments of the birth canal;
  • suppression of a woman’s immune system, necessary to prevent fetal rejection;
  • preventing the maturation of new follicles.

After the baby is born, progesterone is responsible for the formation of maternal instinct. In addition, along with prolactin, it contributes to the suppression of ovulation during the first 6 months of lactation.

Outside the period of gestation

Progesterone is no less important for non-pregnant women, since it is responsible for the health of the reproductive organs and metabolic processes in the body:

  • regulates the structure of the endometrium, in particular, prevents the growth of tumors;
  • acts as an antagonist of prolactin and estrogen, stops excessive proliferation of mammary gland cells, ensuring normal formation of lobes and alveoli;
  • reduces capillary permeability, preventing tissue swelling;
  • enhances sebum production;
  • increases blood pressure;
  • regulates psychological state;
  • ensures complete absorption of energy from food, stimulates appetite;
  • reduces insulin sensitivity of tissues, resulting in a high titer of glucose in the blood;
  • relaxes ligaments and muscles;
  • responsible for normal rheology (fluidity) of blood;
  • reduces immune defense;
  • causes drowsiness;
  • influences the formation of body contours and the development of reproductive organs.

Progesterone is a hormone that has a serious impact on a woman’s condition. It is strictly forbidden to take medications that contain it yourself. This can lead to obesity, depression, muscle weakness and other negative consequences.

Progesterone norm

What level of progesterone should be contained in a woman’s blood? The level of the hormone progesterone in a girl’s blood depends on the period of her cycle.

At the beginning of menstruation (follicular stage), its amount is minimal. Growth begins on days 14-15, that is, during the period of ovulation.

The peak is reached in the luteal phase, when the corpus luteum forms.

If conception does not occur, the temporary gland dies and the concentration of progesterone decreases. When pregnancy occurs, hormone levels continue to increase until delivery, then drop.

Progesterone levels in test results are usually measured in nanograms per milliliter (ng/ml) or nanomoles per liter (nmol/l). To convert nmol/L to ng/mL, divide the value by 3.18.

Standard progesterone values ​​for non-pregnant women of childbearing age (in nmol/l):

  • follicular stage - 0.32–2.23;
  • ovulatory - 0.48–9.41;
  • luteal - 6.99–56.63.

During the postmenopausal period, the hormone concentration should not exceed 0.64 nmol/l. If a girl takes oral contraceptives, then the progesterone level may be as follows:

  • follicular phase – up to 3.6 nmol/l;
  • luteal – 3.02 – 66.8 nmol/l.

Changes in progesterone concentration during the menstrual cycle

During gestation, the normal amount of the hormone is within the following limits (in nmol/l):

  • first trimester - 8.9–468.4;
  • second - 71.5–303.1;
  • third - 88.7–771.5.

Deviations in progesterone levels can occur as a result of taking hormones or the development of a pathological process in a woman’s body. If the norm is slightly exceeded or decreased, it is better to repeat the study.

When and how to take a progesterone test?

Indications

Indications for taking a progesterone test are:

  • lack of ovulation;
  • short luteal phase;
  • infertility in the presence of ovulation;
  • dysfunctional uterine bleeding of unknown etiology (metrorrhagia);
  • disruptions in the menstrual cycle;
  • risk of miscarriage;
  • post-term pregnancy;
  • severe premenstrual or menopausal syndrome;
  • suspicion of a neoplasm in the ovary or pathology of the adrenal glands;
  • side effects from taking drugs containing progesterone - edema, hypertension.

In addition, the analysis may be used for:

  • assessment of the hormonal levels of a woman who has undergone ovulation stimulation;
  • monitoring the condition of the placenta in the second half of the gestation period.

Progesterone is a particularly important hormone during pregnancy, because it helps maintain pregnancy. changes in hormone levels are presented on our website.

Is it possible to increase progesterone in women and how to do it, read.

Video on the topic


In the female body, a special place is given to progesterone, a steroid hormone produced in the ovaries and adrenal glands.
Its functions are directly related to the implementation of the reproductive mission.

The hormone performs a set of tasks aimed at the effective functioning of the female reproductive system. That is why it is so important that progesterone is produced constantly and in the right quantity.

The effect of progesterone on a woman’s body

Under the influence of progesterone, the inner layer of the uterus is prepared for possible conception. He then helps the expectant mother successfully bear the fetus. Not surprisingly, progesterone has another name: the pregnancy hormone. However, the name of this active substance is borrowed from Latin and roughly translated means “gestation.”

Hormone synthesis is actively produced by the corpus luteum long before the moment of conception.

More specifically, the action of progesterone can be represented as follows:

  • Changes the endometrium of the uterus so that the fertilized egg can reliably strengthen and take root.
  • Helps stop menstruation during pregnancy.
  • Prevents epithelial rejection during gestation.
  • Activates the growth process of the uterus. This is necessary because the fetus is growing and needs additional space.
  • Protects against miscarriage, which is possible in case of excessive activity of the uterus. Progesterone helps smooth muscles relax. Thus, it prevents contraction of the uterus, preventing it from pushing out the fetus.
  • Prepares the mammary glands for future lactation, stimulating their development. Shortly before birth, progesterone levels decrease, which allows the uterus to contract and the mammary glands to secrete milk.
  • Has an indirect effect on metabolism and blood pressure.

All this is accomplished subject to fertilization, gestation and birth of the baby.

When there is no conception, the corpus luteum is destroyed, the production of progesterone stops and the woman begins her period.

In addition to functions that ensure conception and support throughout the entire period of pregnancy, progesterone is also active in other processes occurring in the female body. For example, a hormone:

  • does not allow a fibrous cyst to form in the glandular tissue of the mammary gland;
  • maintains optimal blood sugar levels;
  • participates in the normalization of blood viscosity;
  • Helps convert fat tissue into physical energy.

Scientific research in the field of medicine has documented the relationship between two syndromes that are observed in different time periods - premenstrual and menopausal. They appear not only because estrogen levels fluctuate. There is another significant reason - the synthesis of insufficient progesterone.

Maintaining its normal concentration in the body of women is important at any period of life, and not just during pregnancy. Therefore, the hormone level must be constantly monitored. If tests show significant deviations from the norm, detailed examination and therapy are necessary.

Recipe for the occasion::

Progesterone is normal

Progesterone in women's blood is not maintained at the same level. Several factors influence the concentration of the hormone:

  • Finding yourself in an interesting position.
  • Beginning of menopause.
  • Use of oral hormonal contraceptives.

In addition, each individual phase of menstruation is characterized by a certain concentration of progesterone:

At the very beginning of menstruation (phase I), the hormone content is the lowest. Then it gradually increases and reaches a maximum in the middle of the third phase - the period of time between the ovulation process and the onset of menstruation.

The peak activity of the corpus luteum, which intensively produces pregnancy hormones, occurs on the 18th–23rd day (provided that the cycle length is 28 days).

Progesterone concentration may increase to 56.63 nmol/l. And then the process happens again: the follicular phase begins and the hormone level drops.

When, during the period of peak activity, the progesterone level is below 6.98 nmol/l, this indicates that the corpus luteum has certain pathologies. This situation can lead to hormonally dependent ailments, such as mastopathy, uterine fibroids, and endometriosis.

If a woman is taking hormonal contraceptives, the progesterone norm is somewhat different. It should be in the following range:

With the onset of menopause, progesterone is produced in small quantities, because the childbearing period is already behind us. Its normal content in female blood should not exceed 0.65 nmol/l.

Norm of progesterone during pregnancy

In case of successful conception, the level of progesterone does not decline, but continues to increase with each trimester:

The amount of the hormone is significant, since it helps the female body to bear a child and give birth to it safely.

When childbirth occurs, the level of progesterone decreases and after the birth of the baby gradually returns to normal.

Deviation from the norm: progesterone levels are increased

An increase in progesterone levels cannot be ignored. The most positive reason for an increase in hormone levels is the onset of pregnancy. It is doubly pleasant if it was planned in advance.

But there are other reasons that cause progesterone to exceed the norm:

  • uterine bleeding;
  • amenorrhea – absence of menstruation for several cycles;
  • the presence of a corpus luteum cyst;
  • disorders of the kidneys or adrenal glands.

The deviation of progesterone from the optimal level can also be affected by taking certain medications.

Progesterone levels are low

A drop in hormone levels is just as undesirable as an excess of the norm. When test results indicate low progesterone levels, this can be explained as follows:

  • there is no ovulation;
  • the menstrual cycle is disrupted;
  • there is chronic inflammation in the ovaries;
  • the corpus luteum is unable to perform its functions.

A decrease in progesterone levels in expectant mothers may indicate that:

  • there is a threat of spontaneous pathological termination of pregnancy (miscarriage);
  • the likelihood that the embryo may be delayed in development increases;
  • the normal gestational age has been exceeded - post-term pregnancy.

All causes are dangerous and require consultation with a doctor and proper treatment.

So, fluctuations in the level of the pregnancy hormone in both directions outside the normal range need to be corrected. Only a doctor will be able to establish the true causes of such deviations and select the correct therapy.

In addition, it doesn’t hurt to critically evaluate your lifestyle and diet. If you exclude fried, smoked, and fatty foods from the menu, not only will the functioning of the gastrointestinal tract improve, but the production of sex hormones will also be normalized.

The presence of stressful situations negatively affects hormonal balance. It largely depends on the woman’s emotional state and whether the psychological stress is great.

The safest way to improve progesterone levels is to develop a positive attitude. It will definitely help minimize the impact of stress on the female body.

Under what circumstances can it be said that the hormone progesterone is normal in women? What function does this substance perform in the body and is it necessary to monitor its level? Such questions begin to worry the fair half only when the time has come to become a mother, but there are some problems. A detailed answer to this exciting question will be given in the article.

Special hormones in the female body

The main mission of a woman on Earth is the continuation of the human race. The man also makes his contribution, but the main process still occurs in the female body. Nature has taken care of the structure of the reproductive system and the influence of certain hormones on it, the level of which is constantly changing. The amount of hormonal substances is influenced by different circumstances and the woman’s age.

What is progesterone and what is its role in the reproductive process and in the life of the woman herself? It's simple. Progesterone - This is a special hormone that helps a woman’s fertilized egg attach to the walls of the uterine cavity and creates comfortable conditions for the embryo for further development. If progesterone levels are low, then attempts to become a mother without special therapy will end in failure for the woman.

The production of progesterone in a woman’s body is carried out by the ovaries, being the main supplier of progesterone. Additionally, progesterone is synthesized by the adrenal glands and pituitary gland. These are links of one chain, which under normal conditions works smoothly and every month a woman may experience pregnancy or menstruation.

The level of progesterone is important for a woman only when pregnancy occurs. If a woman’s plans do not include becoming a mother, then the girl is not very concerned about the normal indicators.

The main role of progesterone is the following:

  • Progesterone prepares the woman’s reproductive organs for conception, the entire period of pregnancy and a healthy delivery of the woman.
  • Progesterone helps the fertilized egg attach to the walls of the uterus, eliminating the possibility of fetal rejection, which can be perceived by the immune system as a foreign body. Progesterone blocks the activity of estrogen, which can cause miscarriage. Estrogen stimulates the growth of the endometrium in the uterus, its destruction and detachment, which is considered menstruation. During normal pregnancy, progesterone does not allow estrogens to perform their function until the woman gives birth.
  • Progesterone stimulates the lining of the uterine cavity to increase in size as the fetus grows. If a woman's progesterone level is below normal, the embryo will not have enough room to grow due to lack of relaxation of the uterine walls.
  • During the normal course of pregnancy, progesterone helps the expectant mother’s nervous system adapt to the new state until childbirth and during breastfeeding.
  • Progesterone in tandem with the hormone prolactin promotes the normal formation of mammary glands for lactation, eliminating the possibility of cysts forming in the milk ducts.
  • A woman’s maternal instinct is also formed under the influence of progesterone on the body during pregnancy and after the birth of a baby.

These are the main functions of progesterone in the female body, but its role is important not only for the reproductive process:

  • Progesterone is involved in the normalization of metabolic processes - it controls blood sugar and converts internal fat into useful energy.
  • Stimulates the functioning of the sebaceous glands.
  • Increases blood pressure.
  • Progesterone increases sexual desire, especially at a time when there are normal conditions for conception. If pregnancy is not part of a woman’s plans, then she should be more careful during the period when progesterone levels increase.

The well-being and mood of most women during the premenstrual period and during the onset of menopause are also the effects of progesterone.

If for a girl who has not reached the age of menopause, mood swings are the norm and do not last long, then for a mature woman such fluctuations in well-being cause serious discomfort. Therefore, normal progesterone levels are a criterion for excellent mood and normal well-being at different stages of life.

What is considered normal for the female body in relation to progesterone?

A woman’s progesterone levels will differ in the first and second phases of the menstrual cycle, when using special drugs as contraception, or when she has some diseases. For a general understanding of what the norm of progesterone is in a woman, you can study the average indicators obtained at the stage of examining hormonal levels in women of different ages and in the presence/absence of pregnancy.

Normally, a woman’s menstrual cycle lasts from 25 to 33 days (these are individual indicators).

  1. In the first phase of the cycle, the main follicle matures in the ovary, which, when fully matured, ruptures and the stage of ovulation begins - the finished egg is released.
  2. A corpus luteum forms in the follicle, which begins to actively produce progesterone.


If you do an analysis of the level of progesterone in the blood in phase 1 of the menstrual cycle, only residual fragments will be detected, which is considered normal. Progesterone remained from the previous cycle. And only with the formation of the corpus luteum (at the onset of phase 2 of the cycle) will the values ​​begin to increase. The body prepares to maintain the pregnancy if fertilization occurs.

  • If the egg is fertilized and pregnancy develops, then progesterone increases to the maximum possible levels.
  • If conception does not happen, then the level of progesterone decreases, and the endometrium begins its rejection from the placental mucosa, and menstruation begins. This is the monthly norm for women who do not plan to become a mother.

The following tables will tell you what values ​​can be seen in the results of a blood test for progesterone content under various circumstances:

Norm of progesterone in the absence of pregnancy in women of childbearing age

The progesterone norms indicated in the table may change under the influence of contraceptive drugs, which a woman uses on the recommendation of a gynecologist.

These numbers will be lower due to the blocking of the ovulation process.

The same progesterone levels are considered normal during adolescent puberty, lactation and menopause. (progesterone norm 0.64 units/l) .

The norm of progesterone in a woman during pregnancy

The amount of progesterone in a pregnant woman changes at different times, but in the table you can see that the normal level ranges from minimum to maximum values.

It is very difficult for an ordinary person to understand the results and understand whether the level of progesterone in a pregnant woman is normal. Why is there such a large corridor from the minimum to the maximum indicator?

What is clear is that the highest concentration of progesterone is in the third trimester of pregnancy, when normal development of the fetus requires more nutrients, elasticity of the walls of the uterus and placenta. During this period, the formation of the mammary glands occurs, the load on the entire body increases, so the concentration of progesterone should be sufficient for all important processes.


Indicators of the norm of progesterone in a woman’s body are needed only by a gynecologist if the doctor has concerns about a decrease or excess in its concentration. The results obtained about the normality or pathology of progesterone synthesis influence the choice of therapy, if necessary.

Under some circumstances, progesterone levels may be higher than normal at a certain stage. The reason lies in a serious pathology that needs to be excluded. A single analysis of the level of progesterone in a woman’s body may not be enough to determine the clinical picture. Therefore, the examination should be prescribed by a gynecologist, taking into account the general well-being of the patient.

Reasons for deviations from the norm

Pregnancy is not always the cause of high progesterone levels in a woman. Excess progesterone can be a symptom of pathology in the reproductive system or organs associated with progesterone synthesis:

It is possible to lower the concentration of progesterone in a woman if the cause is correctly determined by consulting a gynecologist.

A decrease in the level of progesterone in the body below normal is also dangerous for a woman, especially during pregnancy. Progesterone is responsible for the safety of the embryo, and its deficiency provokes the termination of this pregnancy. Any pathology in the fetus sends a signal to the placenta, which begins the process of rejection, provided by nature as a selection of the strongest.

A change in progesterone levels may indicate a missed abortion or premature birth if a progesterone level test was done at this time. Only such a study is not informative in case of pathology and a pregnant woman is usually indicated by ultrasound or measurement of the level of hCG hormones, CTG.

Rules for testing progesterone levels


An analysis of the hormone progesterone in a woman is not included in the list of mandatory studies, despite the fact that progesterone is important for the female body. The progesterone norm indicators in the tables are only generalized units.

A woman's progesterone level can fluctuate throughout the day and depending on when the blood was drawn, the numbers may be unreliable.

This examination is usually prescribed by a gynecologist if a woman has additional symptoms of hormonal imbalance, for example, problems with conception, failure of menstruation, when preparing for IVF, or when choosing oral contraceptives.

  1. It is advisable to do the test in the morning and on an empty stomach.
  2. The last meal should be no later than 6–11 hours before the collection of biomaterial.
  3. Accurate values ​​can be obtained on the 22nd day from the beginning of the menstrual cycle, provided that the entire cycle lasts 28 days. If the period is more than 32 days, then blood sampling is done on the 28th day.
  4. If your menstrual cycle is unstable, progesterone tests are done repeatedly. To understand which day is better to take a test to determine the normal or pathological level of progesterone, you can measure the temperature rectally after waking up. If the hormone is elevated, then the temperature will be higher than usual. The test is done 6–7 days after the thermometer readings increase.
  5. To determine the norm or deviations in the concentration of progesterone in a woman, blood is taken from a vein.

The results of the test for a woman’s progesterone level are deciphered by a gynecologist at her next appointment.

If the indicators are normal and pregnancy does not occur, the doctor prescribes an additional examination. If progesterone levels are low, a woman is prescribed hormone replacement therapy, which should bring the progesterone concentration to normal.

Any deviations of progesterone from the norm can be compensated

If a woman has a deficiency or excess of progesterone, then to normalize the indicators, the doctor chooses the appropriate therapy:

  • Drug treatment with tablets and injections according to an individual regimen.
  • Using traditional medicine recipes. Infusions of boron uterus, plantain seeds, and mint leaves are popular and effective for normalizing progesterone in women.
  • A diet rich in meat, high-fat dairy, eggs and legumes helps normalize progesterone.

Normalization of progesterone requires constant monitoring of the hormone level to exclude the opposite effect of therapy (increase or decrease in progesterone levels).

Finally

Despite the fact that progesterone plays an important role in the female body, it is difficult to determine the norm for a particular patient. There are only standards. In the absence of additional signs indicating a deficiency or excess of progesterone, there is no cause for concern. In the practice of gynecologists, there are more accurate methods for diagnosing female problems that provide a complete clinical picture than testing the level of progesterone in women by blood.

When planning a pregnancy, you can sometimes encounter problems with progesterone levels. Why is its high or low indicator dangerous? How can I correct it? Let's find out.

What is progesterone

Progesterone is a hormone that the female body needs, mainly during the second period of the menstrual cycle. How it is produced:

  • produced by the corpus luteum of the ovary,
  • adrenal cortex,
  • seminal vesicles in men,
  • placenta in pregnant girls.

Progesterone production is controlled by luteinizing hormone from the pituitary gland and, during pregnancy, by human chorionic gonadotropin (hCG).

Progesterone and estrogen are the most important hormones for fragile women's health. If the long-awaited pregnancy does not occur, then the reason may lie in a change in the level of estrogen or progesterone - both in too high and in low values.

What does progesterone level depend on?

The level of progesterone in a girl’s body is affected by the following: factors:

  • pregnancy;
  • menopause;
  • oral contraceptives;
  • nutrition;
  • stress.

But the phase of the menstrual cycle is of primary importance. The cycle consists of four phases:

  • The first phase is the menstrual phase, which lasts on average 5-7 days.
  • The second phase of the cycle is follicular, the duration of which can be from 7 to 22 days. During this period, the egg matures. Progesterone is produced in very small quantities.
  • The third phase is the shortest (only 3 days) and important - ovulatory. During this time, the mature egg moves into the fallopian tubes. It is now that progesterone levels begin to rise rapidly.
  • The fourth phase of the cycle is the luteal phase. Its duration is more stable and is about 13-14 days. At this time, the corpus luteum begins to produce progesterone especially actively, preparing the body for a possible pregnancy.

If pregnancy has occurred, the corpus luteum will continue to work for about 16 weeks, and the hormone level will increase. If conception does not occur, then the corpus luteum stops functioning, progesterone drops, and after a few days menstruation occurs.

As a rule, a blood test for progesterone is taken on days 23-35 of the menstrual cycle, approximately 7 days before the expected menstruation. What to do if progesterone is too low or high? Do not self-medicate under any circumstances! Be sure to visit a gynecologist-endocrinologist who, after the necessary tests, will prescribe treatment.

Low and elevated progesterone levels

Signs of low or high progesterone may include painful sensations in the mammary glands, bloating, bleeding, and causeless mood swings.

Low progesterone can signal:

  • about the absence of ovulation;
  • about ovarian dysfunction;
  • can be .

For an expectant mother, low progesterone is especially dangerous, as it can cause miscarriage, fetal underdevelopment, or premature birth.

Progesterone levels by day of the cycle

Progesterone is not called the pregnancy hormone for nothing. The hormone, the amount of which increases, is secreted by the corpus luteum. And if conception does not occur, the yellow body dies and menstruation begins.

The level of progesterone in women depends on the phase of the menstrual cycle. If you are interested in the rate of progesterone by day of the cycle, we offer a table that will show how its amount changes.

Norm of progesterone during pregnancy

The rate of progesterone in the body of the expectant mother differs from the rate of progesterone in women who are not expecting a child.

In a pregnant woman’s body, the level of progesterone begins to rise almost from the moment the unborn baby is conceived. Its level becomes higher with each new week of pregnancy.

Please note that the proposed table of progesterone norms during pregnancy is only an approximate level of this hormone in the female body. To obtain an accurate result, medical consultation and laboratory tests are necessary.

Gestational age (in weeks) Progesterone level (nmol/l)
5 - 6 18.57 +/- 2.00

Progesterone in men

Don’t be surprised, but progesterone is also produced in the male body. True, it is lower than in women and amounts to 0.35-0.63 nmol/l.

The hormone is produced by the seminal vesicles of the testicles and adrenal glands. When its amount is within optimal limits, progesterone has a positive effect on men's health. In particular, it regulates fluid metabolism and sugar levels, strengthens bones, improves skin condition, brain function and sleep, prevents prostate cancer, and normalizes thyroid function.

However, if the norm of progesterone in men is exceeded, health problems may arise. In particular, tumor processes become more active. And externally, an excess of the hormone is manifested by the fact that a man’s figure changes, its outline becomes effeminate.

Expertly

Elena Pakhar,Chief physician of the Women's Health Clinic in Domodedovo, obstetrician-gynecologist-endocrinologist, reproductive specialist:“The level of progesterone in the blood in the first half of the menstrual cycle is 0.4-0.8 ng/ml. In the second half, the level of progesterone increases tens of times, on average, to 3 - 30 ng/ml (the indicator depends on the day of the cycle). The maximum activity of the corpus luteum, which produces progesterone, occurs on days 18-23 (if the menstrual cycle is 28 days). If at this time progesterone is below 7 ng/ml, then this is an indicator of hormonal deficiency of the corpus luteum, which can cause hormonal-dependent diseases, for example, endometriosis, mastopathy, uterine fibroids. It is important to monitor progesterone levels during pregnancy. In the first 12 weeks, values ​​from 15 to 25 ng/ml should be considered normal, and by the end of pregnancy - up to 200 ng/ml. Low progesterone levels can cause miscarriage. Progesterone is very important for the normal functioning of every girl’s body, whether she is planning a pregnancy or is already preparing to become a mother.”

Increased progesterone also requires close attention. One of the most joyful reasons for an increase in hormones is the onset of pregnancy. But there are others, less pleasant:

  • corpus luteum cyst;
  • uterine bleeding;
  • dysfunction of the kidneys or adrenal glands;
  • during pregnancy - deviations in the development of the placenta.

As a rule, patients with low progesterone are prescribed its natural or synthetic analogue, individually selecting the dose and duration of treatment. The most popular drugs are Utrozhestan, Progesterone 1%, Duphaston.

Unfortunately, all progesterone-based drugs have a number of unpleasant side effects, including liver dysfunction and the risk of blood clots.

Traditional medicine also does not ignore low progesterone. Typically, all popular remedies (consult your doctor!) are taken in the luteal phase of the cycle, usually in the form of an infusion.
