What should be the norm for progesterone for pregnancy by weeks?

Progesterone norm table for pregnancy

One of the criteria for the successful development of the embryo is the weekly rate of progesterone in pregnancy, which is measured through blood collection at a given time.

The special mission of progesterone for a new life

Women's body of nature created for the possibility of continuation of the human race, which explains the special structure and consistent functioning of the childbearing organs and the influence of hormones.

Progesterone is a pregnancy hormone without which it is impossible to conceive and develop a new life. Gynecology provides for week-specific examinations of a pregnant woman to help her and her future baby avoid serious pathologies.

Progesterone's mission to create normal conditions for future pregnancies begins long before conception. Monthly menstrual cycle in a woman is a large-scale preparation of the body for conception. Progesterone production is provided by the adrenal glands, but most of it produces a yellow body, which is formed during the maturation and rupture of the ovum.

Progesterone prepares the placenta endometrium for the successful fixation of the fertilized cell and its further growth. The yellow body continues to produce the pregnancy hormone for up to 16 weeks unless the embryo has a genetic pathology that leads to freezing and terminating the pregnancy.

There is an opinion that the amount of progesterone other than the accepted norm can provoke a miscarriage.

But the deficiency of progesterone in a woman during pregnancy in the first weeks after conception is only a signal of poor quality biomaterial, which was used for fertilization. If women and men's chromosomal intake is normal, the first weeks of pregnancy are also successful and there is no reason for fetal pathology.

Yellow body receives a signal that the pregnancy is normal and requires more and more progesterone to support the development of a new life. If the embryo dies, the yellow body stops producing progesterone because it is not necessary.

If a woman has a normal pregnancy, the mission of secretion of progesterone moves from the yellow body to the placenta, which is maximally prepared to provide the baby with everything needed.

Measuring progesterone levels in pregnancy up to 12-16 weeks is only relevant for some complaints from women:

  • Bottom pain.
  • Blood emissions, which should not be normal or in a minimum amount.
  • General malaise, toxicosis, pressure surges.

Pregnant women should see a gynecologist who prescribes a laboratory blood test for progesterone levels to determine how the fetus develops.

If progesterone is normal in a pregnant woman

The amount of progesterone in a pregnant woman is not constant and the more weeks after conception, the higher its content. This is considered the norm because as the embryo grows in size, the uterus increases and the entire body of the woman prepares for another major event – childbirth.

If a woman has enough progesterone during pregnancy, this can be understood, even without measuring it for weeks:

  • The pregnant uterus increases in size to make the embryo feel comfortable and develop normally. Insufficient intrauterine space will not allow the baby to grow and normally form the bone skeleton, muscles and internal organs. Growth retardation is a pathology. If the amount of progesterone is consistent with the weeks of pregnancy, it excludes such an abnormality. Smooth uterine muscles are easily relaxed and stretched as the fetus grows, thanks to the effect of progesterone.
  • Progesterone affects the immunity of pregnant women, signaling that the embryo is not an alien cell that needs to be expelled from the uterine cavity. A pregnant woman's body is being rebuilt for the normal development of the fetus and for the necessary nutrients.
  • Progesterone, which corresponds to the norm in weeks of pregnancy, prepares pelvic bones and muscles for labor activity, gradually expanding them for normal passage of the fetus.
  • Progesterone in pregnancy is important for the formation of the breast. Some women can see colostrum secretion from their nipples as early as 30 weeks old. If progesterone is lower than normal, the lactation organs may not be fully formed and the woman will have problems with feeding, there is a risk of condensation, milk stagnation in the ducts.
  • Progesterone is normally involved in the regulation of metabolic processes in women and fetuses during all weeks of pregnancy, because during pregnancy there are special chemical reactions. Stimulates the endocrine and nervous system.
  • The baby, thanks to the maintenance of progesterone levels during pregnancy, develops normally in accordance with the weekly figures assumed in obstetrics as a basis.
  • If the gynecologist doubts the normal development of the fetus at the next examination, the pregnant woman will be assigned an additional examination, which includes a blood test for progesterone levels in a given week of pregnancy.

What progesterone values are considered normal for a pregnant woman can be studied in a weekly grading table:

Pregnancy weeksProgesterone norm digital interval, nmol per litre/ng ml
1-2 (1 to 61 days) from 38 to 57/ from 12 to 18
5-6 from 59 to 69/ from 18 to 21

23-24from 189 to 247/ from 59 to 77
25-26 from 197 to 277/ from 62 to 87
27-28 from 251 to 341/ from 79 to 107
29-30 from 270 to 326/ from 85 to 102
31-32 from 323 to 403/ from 101 to 126

35-36from 322 to 430/from 101 to 136
37-38 from 356 to 468/ from 112 to 147
39-40 from 421 to 546/ from 132 to 172

The weekly table of norms for progesterone levels in pregnancy presents indicators with two types of units of measurement, because each laboratory chooses its own method of analysis and scale of determining the norm.

This should be taken into account when you want to evaluate your own progesterone level. In each column the figures are given in the interval because it is difficult to make an accurate measurement of the hormone content in plasma. Progesterone values are influenced by various factors and the individuality of a pregnant woman's body.

As well as the table of normal pregnancy progesterone content by week, doctors have another table of these values, with the content of the norms of progesterone by trimester of pregnancy, rather than by week. These are more generalized values of progesterone, which can be used as a guide without reference to a particular week. Sometimes the exact date of conception has not been determined.

The period of childbirth is divided into 3 trimesters, in which specific processes of fetal formation and restructuring of the female body, where progesterone is very important.

Pregnancy stage by trimesterDigital interval of progesterone norm, nmol/liter
First38 to 70
Second96 to 247
Three from 197 to 546

All numbers of progesterone norms during pregnancy by weeks and trimesters are generalized indices, which are taken as basic by default. But pregnancy in each woman is individual, so the doctor treating the blood test for progesterone level takes into account the overall clinical picture of the patient.

Woman who saw in his form values that do not meet the standards of progesterone from the table, do not panic and engage in self-treatment.

Weekly values for progesterone

In obstetrical practice, specialists are not inclined to draw conclusions only on the level of progesterone in a woman who is pregnant for weeks, based on weekly norms. The gynecologist's arsenal includes many methods for studying the normal or pathological development of the embryo and the condition of the pregnant woman.

The referral for blood tests for progesterone is given to the patient when she is registered at a women's clinic for a period of 11-12 weeks to determine whether the embryo is attached normally and whether it is developing.

In the first few weeks of pregnancy, progesterone levels may differ from the norm, indicating a pathology of pregnancy. This may be a frozen, ectopic pregnancy, and then the figures in the laboratory form will be higher or lower than normal. This is a reason to do an ultrasound to determine the location of the embryo and to take appropriate measures.

Expulsion from the norm of progesterone in pregnancy for weeks sometimes provoked by taking medication in the treatment of chronic or acute diseases in women.

The list of drugs must be reported to the gynecologist when the pregnant woman is registered, so that the doctor understands that the mismatch in progesterone levels is due to this fact. The risk of fetal threat is assessed, and the medication may be withdrawn in case of dissonance.

In case of low levels of progesterone, especially at early gestational ages, hormonal therapy is prescribed to raise progesterone to normal in order to avoid pathologies in the fetus.

In the last weeks of pregnancy, progesterone levels are highest because the woman's body is preparing for normal delivery and lactation. But the digital values of progesterone may decrease at 39-40 weeks.

For the doctor it is a signal of a carried pregnancy and the need for stimulation of labor.

Embrio does not get enough nutrients and oxygen if the progesterone level is below normal, which is fraught with hypoxia, skin changes and other intrauterine pathologies.

Progesterone and IVF

If pregnancy is naturally impossible, the gynecologist recommends IVF, the success of which depends largely on the compliance of the level of progesterone to specific standards. If this value is low, then an egg replant is useless, it has no chance of being attached to the endometrium.

Progesterone prepares the uterine cavity endometrium for the important event. If the amount of progesterone is insufficient, the fertilized egg will die without the nutrient medium, which is then provided by the placenta.

In case of deviations in the level of progesterone from the norms of women before the IVF session, hormonal therapy is prescribed.

After completing the course, progesterone is measured and if progesterone meets the standards, the biomaterial is replanted into the uterine cavity.

After successful IVF, progesterone is controlled to prevent pregnancy termination.

Pregnancy can be planned with the help of the progesterone calculator service, which will help to determine the auspicious days of conception if the woman has no pathologies.

B Conclusion

Progesterone norm in pregnancy by weeks is an important parameter in a woman's examination, but not the only one. Progesterone compliance or deviation is important only for the gynecologist to correct the embryo development in time to prescribe the correct treatment for the pregnant woman.


Progesterone rate in pregnancy by week, increased or decreased progesterone rate

Progesterone rate table in pregnancy

Progesterone is the norm in pregnancy for weeks – this hormone really needs to be monitored closely. Why is it so important, and what function does it perform?

Progesterone is almost the main role in a woman's body.

Hormone progesterone is responsible for successful fertilization and further successful development of the fetus. Testing for such a hormone is quite informative, and is often used to diagnose the condition of pregnant women and fetuses. The analysis allows you to control and maintain a stable development of the fetus, to find existing problems with development and various violations in time. The results will help reduce the risk of pregnancy termination and the development of some problems.

In order to know the progesterone norm, it is necessary to pass an analysis

Few factors affecting the woman's condition in the process of preparation and bearing of the fetus are quite capable of changing the level of progesterone content.

Hormone levels are affected by many factors: the emotional state of the pregnant woman, the duration of the pregnancy, the use of a number of foods, addiction to bad habits, as well as the use of drugs that affect the hormonal background.

To determine the exact results, the analysis is collected strictly on an empty stomach. Food and water, stop using nine hours before the test. On the eve of the surrender, stress and fatigue are contraindicated. In the case of drugs that affect the hormonal background, taking stops in a few days.

The adrenal glands are responsible for hormone production. Men produce progesterone in the testicles, in a fairly small percentage. In women, progesterone is produced in the ovaries.

Hormone levels fluctuate throughout the menstrual cycle. In the luteal period, the hormone increases significantly. At this point, the ripe egg leaves the follicle for fertilization. On all other days, progesterone levels in the female body will increase, indicating that the woman's body is ready for fertilization and subsequent pregnancy.

Why do you need progesterone in a woman's body?

Exactly progesterone provides all the necessary conditions without which pregnancy is impossible.

Before normal levels of progesterone are present, pregnancy is not possible

Progesterone also contributes to sufficient blood viscosity and controls glucose levels.

Blood viscosity helps to maintain pregnancy at an early stage. Sufficient glucose content provides the developing fetus with nutrition.

Progesterone function:

1. Provides uterine endometrial buildup. This process ensures that the uterine layer of the fertilized cell is “planted” on it and that it is firmly anchored.

2. To prevent the uterus from rejecting the fetal egg, progesterone lowers the activity of the uterine muscles and lowers its tone.

3. In order that the foreign body is not yet rejected, in the form of a fertilized egg (i.e. a future embryo), the hormone suppresses the activity of the immune system.

4. Provides conditions for active cell division, development of the fetal egg. This increases its viability.

5. Responsible for the growth of the epithelial tissue of a future child.

6. Has an impact on a woman's central nervous system. Prepares the mother-to-be rather for motherhood, changing her psycho-emotional state.

7. Uterine enlargement.

8. Launches the accumulation of subcutaneous fat. This process is important enough for a normal pregnancy. Fat is one of the main sources of useful substances, its presence in the mother's body has a beneficial effect on her health, as well as successfully affects the development of the fetus.

9. Promotes the expansion of pelvic bones, which at times facilitates childbirth.

10. Promotes growth of breasts, preparing for further feeding.

Progesterone helps to conceive safely and maintain pregnancy early. It also prepares a woman for a future motherhood, helping to rebuild her body.

Progesterone and pregnancy

Progesterone and pregnancy

After successful conception, the progesterone content begins to rise rapidly. This process is due to the production of the hormone by the yellow ovarian body. Hormone growth lasts up to about 15-16 weeks. After that, the placenta is responsible for the production, which is successfully formed by this time.

Hormone level is stabilized. But it increases systematically in the process of increasing the gestational age of the pregnancy, namely in the process of maturation of the placenta.

Progesterone norm by weeks of pregnancy

Trimester norm:

Period of pregnancy Norm “ng/ml

First trimester 35.5 – 286.1. 20 – 55.

Second trimester 81.3 – 284.5. 24.4 – 81.1.

Three trimester 154 – 1343. 60 – 3134.

At the end of each trimester normal progesterone levels will increase. Normally, the values are raised to the permissible upper limit.

Level is determined in different indicators. Everything depends on the methods and equipment used. The results of the tests performed in different laboratories may be different, but insignificantly different.

These are averages. When checking the tests, the attending physician takes into account the characteristics of each woman.

If the results of the analysis differ from the data in the table, do not panic. The doctor summarizes the results only after a complete set of examinations, including a fairly large number of procedures.

Higher levels of progesterone.

Hormone plays a big role in the body of every woman and mother, and it is not definitely worth neglecting the passing of the analysis. As has been said, the results can tell a lot about the health of women and fetuses. Most often, this study is performed in the last two trimesters of pregnancy.

In the first trimester, progesterone levels are determined if there are suspected problems. Tests are performed on women with possible miscarriage threats or complications. You should also take an analysis if you have any diseases of the genitourinary system.

Performance is not often higher than normal, but in cases where performance significantly exceeds the upper limits, these results should be considered in more detail.


  • frequent headaches
  • fatigue occurring without obvious physical activity
  • uterus exceeding the normal size
  • /li>

  • frequent bleeding
  • increased drowsiness, fatigue
  • < nausea, heartburn, bloating and constipation.

Multiplying indicators are able to “say” about availability:

  • Expanding ovarian cyst
  • On changes in the positive development of the placenta
  • On changes in the positive development of the placenta
  • Kidney failure
  • Higher blood sugar.

As well as elevated levels of this hormone may indicate a multiple pregnancy, as well as be a consequence of taking hormonal drugs with a synthetic analogue of this hormone. Other drugs can also affect elevation.

In cases of elevated blood hormone levels, the attending physician will prescribe additional tests to determine the cause.

Lower progesterone

Progesterone deficiency is much more common in pregnant women. A lower level also exposes the female body and the developing fetus to many risks.

In the case of low progesterone levels, pregnancy may not occur

In the case of low progesterone levels, fertilization may not occur.

Reduced progesterone is the cause of poor fertilization, early termination of pregnancy. Also, because of the insufficient amount of progesterone produced, pregnancy cannot proceed safely. How does a reduced level of progesterone appear: increased uterine tone, excretion with bleeding marks, pulling and aching pains in the abdomen, giving into the back, detachment of the placenta.

External signs: frequent mood swings, aggressiveness, increased irritability; increased sebaceous glands activity; frequent pressure drops; bloated abdomen, sometimes with constipation; temperature drops.

What is at risk of reduced progesterone:

  1. Birth, termination of pregnancy.
  2. In uterine pregnancy.
  3. Seased pregnancy.
  4. Fetal development fatigue.
  5. Insufficiency of the yellow ovarian body.
  6. Multifunctional disorders of the placenta and fetus.
  7. Hestosis.
  8. Expansion of pregnancy.
  9. Development of inflammatory processes.

Progesterone reductions are affected by the drugs taken by women during this period.

Progesterone percentages should be raised for successful pregnancy and fetal bearing. Dufaston.

The same is true for injections, especially when there are obvious threats of termination of pregnancy.

Pregnancy is an important and significant period in the life of every woman. For such a wonderful period to succeed, it is necessary to monitor the health of the child at the stage of planning the birth of the child. Women's health is a guarantee of child health

During pregnancy in the female body is activated the production of certain hormones, including progesterone. It belongs to the class of steroid hormones.

In women, progesterone is produced mainly by the yellow body of the ovary (during the luteal phase of the menstruation cycle). It is often referred to as the “hormone of pregnancy” and it is the hormone that causes the first signs of pregnancy.

In much smaller amounts it is synthesized by the adrenal cortex.
