Table of estradiol norms during pregnancy by week

Estradiol during pregnancy

Hormones play an undeniable role in human life

This is especially important during the birth of a new life.

The body of a woman who will soon become a mother undergoes colossal hormonal changes several times from conception to childbirth. Perhaps one of the key places is occupied by estradiol during pregnancy.

Its quantity and dynamics can determine the course of pregnancy and indicate possible problems.

Preparing for analysis

Estradiol is considered to be the most active and most “female” hormone. It belongs to the group of estrogens, steroid hormones, along with estriol and estrone.

Estradiol is produced by the ovaries and adrenal cortex. With the onset of pregnancy, the placenta is responsible for its production. Other names of the hormone used in medicine are E2, 17 beta-estradiol, 17 beta-diol, dihydroxyestrin, dihydroxyestratriene, dihydroteelin.

The level of estradiol during pregnancy should normally increase significantly, reaching its maximum by childbirth.

In order for the result of the analysis to be informative and reliable, you should prepare for it correctly. First of all, you need to be in a positive mood and not be nervous.

It is best to take blood samples in the first half of the day, preferably on an empty stomach. A few days before the test, you should avoid fatty foods, alcohol and cigarettes. It is also not recommended to have sex.

Direct Impact

Estradiol is responsible for the formation of a female-type figure, for the formation of fat folds in the abdominal area (to protect the unborn fetus from possible damage).

The development of the uterus, tubes, the formation of the vagina, mammary ducts, and regular menstruation cannot occur without the participation of the hormone. Women's menopause is a reaction to a decrease in the concentration of estradiol in the body. Normally, it is present in small quantities even in men.

It is noteworthy that low concentrations of the hormone in both women and men lead to infertility.

By the way, if estradiol is elevated during pregnancy, then this phenomenon is not considered a strong pathology, provided the woman has moderate swelling. In the latter case, it will be necessary to take measures to eliminate swelling.

More hormone means better blood clotting. Significantly exceeding the norm of indicators entails increased irritability and sudden mood swings in the pregnant woman. Also, the higher the indicators, the stronger the pigmentation during pregnancy - darkening of the nipples and groin area.

The real danger is caused by low levels of the hormone in the expectant mother. Indicators below acceptable limits indicate that the pregnant woman’s placenta is in poor condition. There is a real threat of miscarriage and premature endometrial rejection. Therefore, if the test result shows a lag behind the norm of estradiol, special hormonal support is urgently prescribed.

Standard values

Standard levels of hormone concentration before pregnancy depend on the phase of the cycle. So in the follicular phase the norm will be a value in the range of 69-1270 pmol/l, at the peak of ovulation - 132-1650 pmol/l, and in the luteal phase the amount of estradiol will be 90-860 pmol/l.

With the onset of menopause, the inevitable processes of loss of the female hormone begin and the average value does not exceed 72pmol/l. An interesting fact is that within a week or two after giving birth, hormone levels return to normal. And estradiol reaches its greatest value in pregnant women.

A woman’s desire for the result of her analysis to determine the concentration to correspond to the norms of estradiol during pregnancy by week is quite natural. For orientation purposes, an approximate table of acceptable values ​​is displayed.

Table - Estradiol during pregnancy norm by week

Pmol/l - picomoles per liter, means the amount (picomoles) of the test per liter of plasma, pg/ml - dissolved hormone (picorgammas) in one milliliter. The second indicator is considered more accurate.

It all depends on the capabilities and technical equipment of a particular laboratory.

Therefore, before starting a comparison, you should pay attention to the values ​​in which the result was produced.

The general health of a woman is very important both for pregnancy and for bearing a fetus. It is not entirely correct to say that estradiol itself is responsible for all the troubles

Since the body is a single whole, if there are hormonal disruptions, then there are factors that precede them.

The hormone estradiol during pregnancy

Estradiol is one of the most important female hormones, as it plays an important role during pregnancy, and therefore deserves special attention. Together with progesterone, they regulate the normal course of the pregnancy cycle; its concentration increases during fetal development and reaches its maximum immediately before childbirth.

This hormone is related to the steroid hormones estrogen. It also has several names, such as: E2, dihydroxyestrin, dihydroteelin, 17 beta-estradiol, dihydroxyestratriene, 17 beta-diol.

In women in normal conditions (not during pregnancy), estradiol is synthesized by the adrenal glands and ovaries, and its concentration directly depends on the phase of the menstrual cycle. Its concentration increases in the first half of the period of monthly secretion, and in the second it gradually decreases. In pregnant women, it is produced by the placenta immediately after its formation, that is, immediately after the start of pregnancy.

The level of estradiol returns to normal levels a week after birth, and with the onset of menopause it decreases to the level of concentration in men (from 19.7 to 242 pmol/l). Menopause is directly related to a decrease in this hormone. Also, in addition to the participation of this hormone in the pregnancy process, it has several other functions.

He is responsible for:

• endometrium of the inner layer of the uterus and its general formation;
• starting blood circulation in the uterine vessels and regulating their normal functioning, which is extremely important for the normal course of pregnancy;
• formation of a characteristic female phenotype (appearance, body curves) and internal organs;
• development of the reproductive system;
• thickening of the fat layer in typical female areas such as the thighs and abdomen;
• support of vitality and activity of the body.

If the hormone level is higher or lower than normal

It may happen that the concentration of these substances in the blood increases for some reason. Estradiol may increase during pregnancy if:

• the woman is overweight;
• takes certain medications (for example, steroids), including hormonal ones;
• there are disturbances in the functioning of the endocrine system, in particular the thyroid gland;
• liver cirrhosis was diagnosed;
• there are benign neoplasms in the ovaries or uterine cavity, for example, follicular cysts;
• diagnosed with endometriosis.

Symptoms indicating an increase in the level of this hormone in the blood include sudden emotional swings, irritability, aggression, moodiness and tearfulness, mood swings for no apparent reason. Sometimes soft tissue swelling is observed.

As a rule, an increased concentration of estradiol in the blood does not pose a threat to the fetus or the mother’s body. This condition is only controlled, and normalization of the level of this substance occurs by itself. Otherwise, for example, in the presence of serious extensive edema caused by high estrogen levels, measures are taken to eliminate them.

A decrease in estradiol levels during pregnancy requires medical monitoring and intervention. This condition can occur when:

• taking certain medications;
• unhealthy lifestyle, in particular smoking and alcohol abuse;
• poor nutrition and weight loss;
• prolonged stress and heavy physical activity;
• chronic inflammatory processes of the genitourinary system.

In the blood during gestation, it increases the risk of delayed fetal development and the threat of miscarriage. Therefore, when diagnosing such conditions, urgent measures are taken to normalize the level of estrogen in the blood in the form of hormonal therapy with estrogen-containing drugs.

If we talk about women in menopause, then a decrease in the level of this hormone is physiologically justified and has its consequences in the form of “hot flashes”, decreased libido, genital atrophy, irritability, diseases of the musculoskeletal system and insomnia. To ensure a smoother progression of menopause and the transition to true menopause, such women may be prescribed hormone replacement therapy.

Increased level

An increased amount of estradiol during pregnancy is not scary, unlike a lack of the hormone . Sometimes a high concentration is due to the individual characteristics of the body, so a slight excess of the norm is considered physiological characteristics.

Symptoms

There are not many symptoms of elevated estradiol . This:

• severe swelling and sudden mood swings;
• aggressiveness;
• irritability and nervousness.

Sometimes darkening of the halos of the nipples and external genitalia is observed. But these signs are often detected during pregnancy, so it is extremely difficult to suspect excess estradiol.

Causes

The reasons for the increase in estradiol are as follows:

1. overweight or obesity;
2. cirrhosis of the liver;
3. genital endometriosis;
4. thyroid diseases;
5. follicular cyst in the ovary;
6. various neoplasms in the uterus.

A prerequisite for an increase in estradiol may be the use of certain medications, for example, anabolic steroids.

Consequences

Elevated levels of estradiol in the blood do not pose a danger to pregnancy. Some experts even argue that this is more of a plus than a minus, since the likelihood of bleeding during childbirth is minimal.

Treatment

The symptom itself—an increase in estradiol—does not require specific treatment. If it is associated with pathological conditions, diagnosis and treatment are postponed until a more favorable period - after the birth of the child.

If severe swelling occurs as a result of increased estradiol levels, therapy may be aimed at reducing it. In this case, it is necessary to correct the diet (diet), reduce the amount of fluid consumed and take medications (diuretics). The doctor decides on the need for drug therapy, so self-medication is prohibited.

Indicators for analysis

Before pregnancy, hormone levels change based on the phases of the cycle. For example, at the peak of ovulation, the concentration of estradiol ranges from 133 to 1650 pmol/l. In the follicular phase, the normal value is from 69 to 1270 pmol/l. The concentration of estradiol in the luteal phase is from 90 to 860 pmol/l.

When menopause begins, the female hormone estradiol is produced in a smaller volume and does not exceed 72 pmol/l. Interestingly, 7-14 days after birth the hormone returns to normal values. Peak values ​​of this hormone are reached closer to childbirth.

USEFUL INFORMATION: Ectopic WITHOUT tubes is possible

Pmol/l – picomole (amount of estradiol) per 1 liter of plasma, pg/ml – dissolved hormone in picograms per 1 milliliter.

Estradiol belongs to the group of estrogens - female hormones. It is the most effective hormone of this group, the rest are considered auxiliary. With its help, a female body type is formed (narrow waist, rounded chest and hips), genital organs develop, secondary sexual characteristics appear, and the voice becomes high and thin. It also affects the emotional state of a woman, shaping the qualities inherent in a woman’s character.

The effect of estradiol on the genitals is expressed in maintaining their health, as well as stimulating the release of the egg from the follicle in the ovary. Follicles mature every cycle, and it is estrogens that stimulate their maturation. After the release of the egg and in the absence of fertilization, their level decreases, and at conception it begins to increase. Therefore, the level of estradiol during pregnancy is significantly higher than during pregnancy.

Estrogens are necessary to normalize metabolism, including in bone tissue, maintain body tone and a woman’s mood, control the functioning of the cardiovascular system and reduce cholesterol levels.

Maintaining pregnancy with estradiol

For any person, regardless of gender, the presence of a hormone is the norm. For men, a small amount is typical, for women – a larger amount. Estradiol is of particular importance for gestation, so its concentration during pregnancy reaches its maximum.

The hormone is usually produced by the ovaries and adrenal glands. It is based on male testosterone. Estradiol levels are constantly changing, which is associated with the phases of the menstrual cycle. A significant increase will be observed from the moment of conception. During this period, the placenta synthesizes the hormone.

Along with progesterone, estradiol is of primary importance during pregnancy. It is responsible for the full bearing of the child, ensures the growth of the uterus and its development, controls the condition of the vessels and blood circulation in them. Estradiol also affects blood clotting, which is important to prevent possible bleeding, including during childbirth.

The hormone also has an effect on the general condition of the pregnant woman. It can cause irritability and nervousness. Swelling is also the body’s reaction to an increased amount of estradiol. It prevents water and sodium from being fully excreted.

Increases hormone levels and excess weight, which is associated with its synthesis by fat cells. Medications can also provoke this situation.

An increased concentration of estradiol is better than a decreased one. In the latter case, there is a risk of miscarriage, which is caused by pathological development of the placenta.

Estradiol during pregnancy, hormone norm by week

In human life, hormones play a very important role in regulating the functioning of organs and important processes occurring in the body. At the time of pregnancy, this function of hormones is especially important. The hormone estradiol is the most active sex hormone in women. Therefore, it plays a key role among hormones during pregnancy.

It is very important to monitor the amount of estradiol (during pregnancy), the process of fetal development directly depends on these indicators. The dynamics and amount of estradiol reflect the progress of pregnancy

Monitoring the levels of this hormone will help identify disorders and possible health problems.

Estrodiol belongs to the group of estrogens (steroid hormones). It is produced by the ovaries and adrenal cortex in women. Estradiol is produced in small quantities by the testes in men. In medicine, estradiol is designated as follows: E2, 17 beta-diol, dihydroxyestrin, 17 beta-estradiol, dihydroxyestratriene and dihydroteelin.

During normal pregnancy, estradiol levels increase greatly. Its maximum level is reached closer to childbirth.

In medical practice, it is customary to regularly prescribe estradiol tests throughout pregnancy. This approach allows you to monitor a woman’s health status for possible deviations from the norm.

It is very important to monitor estradiol levels during pregnancy to prevent the risk of bleeding, fetal death or miscarriage

How to prepare for the analysis?

Proper preparation for analysis is very important. In order for the analysis results to be accurate, the first thing that is required of you is a good mood. You should not be nervous before taking an estradiol test.

Blood sampling is done before lunch (in the first half of the day). Blood is donated on an empty stomach. A couple of days before the test, you need to give up fatty foods. Sexual intercourse should also be stopped 2 days before the test.

What is estradiol responsible for?

One of the differences between a man and a woman is the figure. Estradiol is responsible for the formation of the female figure. This hormone promotes the formation of belly fat. This is necessary to protect against possible external damage to the fetus.

For you to understand how important the hormone estradiol is for a woman, it is enough to list some of its functions: the development of the fallopian tubes, uterus, vagina, mammary glands and their ducts, the menstrual cycle.

For example, menopause is a reaction to a decrease in estradiol levels.

The male body also produces small amounts of estradiol. Interestingly, if the amount of the hormone estradiol in a man is less than the prescribed norm, this can lead to male infertility.

Thanks to the normal concentration of estradiol, the uterus and its vessels, as well as the placenta, develop without deviations. Blood clotting cannot occur without the influence of estradiol. Even your mood during pregnancy partly depends on the level of this hormone.

If estradiol levels are high during pregnancy, swelling may occur. This symptom causes discomfort and the doctor should take measures to eliminate it. During pregnancy, estradiol should increase, this is normal.

The more of this hormone in the body, the better the blood clotting indicators. If the concentration of estradiol is greatly exceeded, a pregnant woman may experience frequent and sudden changes in mood.

One of the symptoms of excess estradiol levels in a pregnant woman is darkening in the nipples and groin area.

High levels of this hormone are not scary. A low estradiol level in a pregnant woman poses a great danger. With low estradiol, the condition of the placenta worsens. A miscarriage may occur. If, according to the results of the analysis, estradiol is below normal, the woman is immediately prescribed a course of hormonal therapy.

Indicators for analysis

Before pregnancy, hormone levels change based on the phases of the cycle. For example, at the peak of ovulation, the concentration of estradiol ranges from 133 to 1650 pmol/l. In the follicular phase, the normal value is from 69 to 1270 pmol/l. The concentration of estradiol in the luteal phase is from 90 to 860 pmol/l.

When menopause begins, the female hormone estradiol is produced in a smaller volume and does not exceed 72 pmol/l. Interestingly, 7-14 days after birth the hormone returns to normal values. Peak values ​​of this hormone are reached closer to childbirth.

For information, below is a table of estradiol indications during pregnancy by week.

Pg/ml is the most accurate parameter. If the laboratory is more or less modern, then the report on the analysis of estradiol will be presented according to this parameter

Please note this before ordering an analysis.

What is estradiol and what is its role during pregnancy

Estradiol is a hormone in the female reproductive system, the natural production of which determines the health of the body’s reproductive system.

The level of this hormone determines the possibility of normal functioning of the ovaries, uterus, mammary glands, fallopian tubes, as well as the condition of the vagina and vulva.

The amount of the hormone always depends on the condition of the female body, the presence of pregnancy or the phase of the next menstrual cycle. The level of estradiol during pregnancy constantly increases, reaching maximum levels at the onset of labor.

It is this hormone that is responsible for maintaining pregnancy and preparing for childbirth, which consists of increasing blood clotting to prevent possible bleeding during childbirth. Also, estradiol during pregnancy is responsible for the condition of the placenta, uterine vessels and normal blood circulation in them.

Estradiol production occurs primarily by granulosa cells in the ovaries. The hormone is also synthesized by the adrenal glands and adipose tissue. During pregnancy, this function is taken over by the placenta.

In the absence of pregnancy, during the follicular phase of the menstrual cycle (from 1 to 14 days), the level of estradiol increases and reaches its maximum value by the time of ovulation.

With the beginning of the luteal phase, if conception has not occurred, from days 16 to 28 the hormone production decreases, and the concentration becomes minimal before the start of the next menstruation.

It is estradiol that in each menstrual cycle stimulates the process of preparing the uterine mucosa for implantation of the embryo and further development of the fetus.

Blood test for estradiol

If your attending gynecologist asks you to donate blood for E2, take this seriously, because otherwise the test may turn out to be unreliable.

In order to properly prepare for the test, you should know:

• do not feel nervous and overexcited even by positive things;
• blood for analysis must be donated in the first half of the day, in the morning before lunch;
• the day before the test, you should not engage in coitus (sexual intercourse), eat fatty foods, engage in physical labor or strenuous physical exercise, or smoke or drink alcohol. Although the latter is strictly prohibited during pregnancy;
• If you use medications and dietary supplements (dietary supplements), you should notify your doctor. He will most likely order you to stop taking it two days before the test, unless, of course, your life directly depends on taking the medication.

USEFUL INFORMATION: No sperm at 13 years old

Understand that violation of any of the above points may distort the results of the analysis and subsequently you will have to take it again or you will be prescribed treatment that is incorrect for your situation, which will lead to even more complex problems.

Depending on the technical equipment and capabilities of the laboratory, two types of estradiol measurements are possible - pmol/l (general result) and pg/ml (more specific result). Both options have their own standards, which are indicated in the table below:

How to take a hormone test correctly to get reliable results

If the doctor has prescribed a blood test to measure the level of estradiol and other hormones, you need to properly prepare for it so that the result obtained is as reliable as possible.

There are a number of rules that must be followed when preparing for such an analysis:

1. Blood sampling should be done in the morning before noon.
2. The day before blood sampling, you should refrain from sexual intercourse, drinking alcohol, smoking, doing physical work, playing sports, as well as eating heavy fried and fatty foods.
3. On the eve of the test, you should not be nervous or overexcited, even if your emotions are positive. The nervous system must be at rest.
4. If you are taking medications, their use should be discontinued 2-3 days before the planned blood draw for analysis (if possible).

Proper preparation for the analysis is important and failure to comply with at least one point may lead to unreliable data.

At the same time, estradiol during pregnancy may be not only increased, but also decreased, which will require taking urgent measures, which at best may turn out to be unnecessary, and at worst, lead to serious and dangerous complications.

Characteristics of the hormone

Estradiol is the main and most active female sex hormone, which is part of the estrogen subclass. It is produced to a greater extent in the ovaries, in small quantities - by the adrenal glands, and its main purpose is to prepare the female body for pregnancy. This hormone also affects the condition of the skin, the absence/presence of wrinkles, a cheerful state of mind, high physical activity, and endurance. In addition, he:

• stimulates egg maturation;
• affects increased blood flow in the uterus;
• promotes thickening of the inner mucous layer of the uterus, the width of which should be at least a centimeter by the time the egg leaves the follicle;
• improves blood clotting;
• accelerates the formation and renewal of cells, tissues, muscles;
• strengthens blood vessels;
• retains sodium and water;
• participates in metabolic processes in bone tissue;
• lowers cholesterol levels;
• has a calming effect on the nervous system.

The amount of estradiol in the blood is unstable and constantly fluctuates. The highest rates are recorded between three and six o'clock in the afternoon, the lowest - from midnight to two in the morning. The level of the hormone is influenced by the woman’s health, as well as the menstrual cycle: as soon as one of the follicles of the egg begins to actively grow and the egg matures in it, it begins to secrete estrogens, signaling the uterus that it is time to prepare for conception.

By the time the follicle matures, the level of estradiol in the body is so high that the hypothalamus, one of the parts of the brain, signals the pituitary gland to increase the production of the hormones LH and FSH, which are responsible for the functioning of the body’s reproductive system. As a result of the surge, when FSH and LH reach their maximum levels at this moment, the follicle ruptures and the egg that has matured in it is released, beginning to move towards the uterus.

After this, the level of estradiol drops to a minimum, and the corpus luteum formed at the site of the ruptured follicle begins to actively synthesize progesterone. True, such a decline is short-lived, and on the ninth day the level of estradiol increases again, reaching a second peak, although much lower than during ovulation and decreases again.

Concentration rate

Depending on whether a woman is pregnant or not, it is customary to talk about different levels of the hormone in the blood. So, for women who are not pregnant, the rate of the indicator will depend on the phase of the menstrual cycle:

• follicular phase - from 69 to 1270 pmol/l;
• ovulation period - from 132 to 1650 pmol/l;
• luteal phase - from 90 to 860 pmol/l.

In men, the normal level of estradiol in the blood is considered to be up to 72 pmol/l. Interestingly, in women during menopause, the level of estradiol in the body is close to that of men, but the level of another, estrone, increases.

When talking about estradiol levels in a pregnant woman, one should understand much higher concentrations, and the higher they are, the longer the gestational age. Thus, the normal levels of this hormone in the blood of pregnant women are given in the table below.

The level of the hormone in the blood decreases to non-pregnant levels in the first weeks after childbirth.

Unaware of her situation, it can be noticeable to the naked eye and is reflected in the appearance of the expectant mother. Sometimes they say that a woman has “bloomed”, her shape is rounded, her breasts become firmer, men notice her attractiveness.

Normal during pregnancy

In the early stages

The amount of estradiol in pregnant women begins to increase from the very first weeks, but reaches its highest concentration in the later stages.

Before pregnancy, the analysis normally shows a concentration from 69 to 1650 pmol/l depending on the phase of the cycle, and already, for example, at week 5 it can increase to 5400.

The normal values ​​for estradiol levels during pregnancy in the first trimester are given by week:

• 1-2 weeks : 800-1400 pmol/l;
• 3-4 weeks : 1400-2500 pmol/l;
• 5-6 weeks : 4000-5400 pmol/l;
• 7-8 weeks : 5100-6400 pmol/l;
• 9-10 weeks : 6000-8400 pmol/l;
• Week 11-12 : 8400-11400 pmol/l.

In modern clinics, a different measurement is usually used - pg/ml, then the values ​​will be different. The doctor deciphers the results, so the woman does not have to worry about this.

In the 2nd trimester

In the second trimester, the concentration of estradiol continues to gradually increase and reaches the level:

• 13-14 weeks : 10100-16000 pmol/l;
• 15-16 weeks : 11500-16500 pmol/l;
• 17-18 weeks : 16700-28400 pmol/l;
• 19-20 weeks : 17500-29500 pmol/l;
• 21-22 weeks : 30300-42200 pmol/l;
• 23-24 weeks : 33000-47500 pmol/l;
• Week 25-26 : 40000-53200 pmol/l.

By the end of the second trimester, the amount of the hormone increases to almost maximum levels. In the last weeks of pregnancy, concentrations still increase, but at a slower rate.

In the 3rd trimester

In the third trimester, the amount of estradiol varies from 42,500 to 80,000 pmol/l. But you need to understand that there is no norm in analyzes: it is relative.

The quantitative parameters of other hormones, the woman’s age, the number of fetuses in the womb, and the presence of any diseases are taken into account. For example, during multiple pregnancies, estradiol levels may be even higher.

Blood estradiol level

As mentioned above, estradiol affects the tone of the female body, therefore, if there is a deficiency, a woman feels lethargy, loss of performance, apathy and fatigue, as well as more serious “female-like” problems: vaginal dryness and the ensuing difficulties with conceiving a fetus.

If E2 decreases during pregnancy, this is the first sign of problems with the placenta, and this is already a serious threat to the fetus, including miscarriage, and therefore requires urgent treatment.

The most common treatment in this case is the prescription of a course of medication aimed at increasing the level of the desired hormone - these can be tablets, patches, or injection solutions. Also, such drugs are used when labor is delayed to stimulate its onset.

If the level of estradiol increases during pregnancy, a woman experiences nervousness and irritability, as well as swelling. Although the increased content of the hormone increases blood clotting and reduces blood loss during childbirth, this is an undeniable plus.

We can come to the conclusion that an increase in the hormone is not as dangerous as its decrease. In addition, an increase can be caused by an increase in the amount of fat in a woman’s body, because fat also produces E2, and a decrease already threatens serious problems, and therefore requires urgent treatment.

When is the test taken?

A pregnant woman who does not understand the role of estrogen is at risk - she will not be able to bear it if there are more male hormones than female ones. It is advisable to find out about hormone deficiency while planning pregnancy. This way the woman will protect herself from problems during pregnancy.

Donating blood during early pregnancy is necessary for those patients who were unable to bear a child in the past and experienced a miscarriage. Anyone who wants to check their hormone levels just to be less nervous can donate venous blood for analysis at any time. For those who are still planning a pregnancy, it is recommended to do the test on the 5th day of the monthly cycle or on 21-23.

It is not necessary to donate blood for estradiol, but if you have chronic problems with the thyroid gland, it is better to check yourself. With hyperthyroidism or hypothyroidism, there is a high probability of abnormalities in the development of pregnancy. It is also advisable for girls with irregular periods to get tested in the first trimester to make sure that the hormone level does not fall below normal.

How often do you get your blood tested?

Low estradiol during early pregnancy is a dangerous phenomenon.

And doctors have to prescribe synthetic drugs in tablets or patches.

Submission rules

To get reliable results of a blood test, you need to take the test according to all the rules.

1. In the morning, on an empty stomach.
2. 2 days before going to the doctor, do not take any pills or smoke.
3. It is contraindicated to go to training.

In gynecology there are clear standards for hormone levels. If the test result is below normal due to medications or physiological factors, the doctor is required to prescribe synthetic hormones. During early pregnancy, getting tested correctly is vital for the unborn child.

Test for estradiol during pregnancy

An estradiol test usually involves determining the level of this hormone in the blood, but in some cases the amount of estradiol is also determined in the urine. Percentages can also be calculated, which will reflect the metabolism of the hormone in the blood.

Drawing venous blood requires special preparation. During pregnancy, an estradiol test is performed on an empty stomach (you should not eat 8 hours before the test). You should also not smoke, as nicotine will affect the quality of the result, and smoking itself is completely incompatible with pregnancy. On the eve of the examination, physical activity and sex should be excluded.

Reduced estradiol levels during pregnancy

A decrease in estradiol can occur even before pregnancy. In this case, the woman suffers from infertility for a long time, since the low level of estrogen does not lead to the changes in the reproductive organs that are necessary for pregnancy to occur. Ideally, such women are prescribed hormone replacement therapy at the stage of pregnancy planning and continue for some time during pregnancy, since a reduced estrogen level during pregnancy leads to various complications, including the threat of miscarriage.

Estrogens take an important part in the regulation of the menstrual cycle, as they contribute to the proliferation of the endometrium, that is, the uterine mucosa thickens so that when pregnancy occurs, the fertilized egg has a place to implant. It is clear what happens when there is not enough estradiol - even when pregnancy occurs, the fetus does not stay in the uterus, it passes through in transit

Therefore, corrective hormonal treatment is required. The most commonly prescribed estrogen drug during pregnancy is Femoston 2/10; it helps to effectively treat existing disorders.

Increased estradiol levels during pregnancy

Most often, if estradiol is elevated during pregnancy, then the woman is carrying a girl. This condition does not pose any danger, but in some cases signs of a threatened miscarriage may develop (this is probably not associated with an increased level of estradiol).

Thus, estradiol is the second most important hormone after progesterone, which allows you to carry a pregnancy to term normally, preventing the development of various complications (threat of miscarriage, placental insufficiency, etc.). Obstetrician-gynecologist Marina Slavina

The effect of elevated estradiol on pregnancy

Elevated estradiol levels during pregnancy are normal. It is associated with lower risks for bearing a child, reduces the risk of bleeding during labor, and accelerates the recovery of the mother's body. No special treatment is carried out in this case.

Also, pathologies may indicate increased concentrations of estradiol in the body, but as a rule, problems are detected before pregnancy:

• obesity;
• cirrhosis of the liver;
• pathologies of the thyroid gland;
• endometriosis;
• presence of neoplasms.

Elevated estradiol during pregnancy may be associated with the use of medications, including hormonal ones.

What is estradiol

Estradiol (17β-estradiol; dihydroxyestrin; dihydroxyestratriene; dihydroteelin; 1,3,5-estratriene-3, 17β-diol; E2) is one of the strongest female sex hormones, the most biologically active hormone from the estrogen group, classified as steroid. Under its influence, a woman’s reproductive system, her (in particular, the uterus), and the outlines of her figure are formed. It is responsible for reproductive function; with the participation of estradiol, the menstrual cycle is established and regulated, it determines a woman’s sexual desire and sexual behavior. Even the deposition of fat in problem areas (which is typical only for women) is caused by estradiol.

If the level of estradiol in a woman’s blood is low, she cannot become pregnant. What’s interesting is that when the level of this hormone is low, men also experience infertility. And during pregnancy, the level of estradiol in a woman’s blood increases to its maximum levels. It constantly grows, reaches a peak a few days before birth and then returns to normal (on the fourth day after the birth of the child). With age, the level of estradiol in a woman’s blood drops, and after menopause, it becomes equal to what is found in a man’s blood.

The level of estradiol during pregnancy reaches maximum levels in comparison with its levels in a non-pregnant woman, since the hormone is of decisive importance for bearing the fetus. The table shows the norms of estradiol during pregnancy:

Low estrogen levels

Main reasons:

• physical exercise;
• excessive thinness;
• low carbohydrate diet;
• lack of meat in the diet;
• high prolactin levels;
• taking certain medications;
• diseases of endocrine organs.

Low estradiol during pregnancy must be restored with hormonal therapy. For this purpose, special medications are selected that are approved during pregnancy.

You can also adjust your diet to include foods rich in phytoestrogens. To do this, you need to eat more cereals, legumes, and nuts. Traditional medicine has many recipes for herbal decoctions that help increase estrogen levels without harm to the unborn child.

Flax seeds are one of the richest foods in phytoestrogens.

Signs of decreased estradiol

A low level of the hormone is much more dangerous for the course of pregnancy and may indicate quite serious disturbances in the development of the fetus, up to the threat of spontaneous abortion.

This condition also has a negative impact on a woman’s health. She experiences:

• constant fatigue;
• lethargy;
• dry skin.

In most cases, low estradiol during pregnancy is the cause of the development of osteoporosis and significant weight loss. In the third trimester, its deficiency provokes post-maturity and absence of labor.

Causes of decreased hormone levels in the blood

Indicators can fall below normal due to a fairly wide range of risk factors. Let's look at the most common ones:

• unbalanced diet;
• refusal of meat;
• high physical activity;
• bad habits;
• malfunction of the pituitary gland;
• chronic diseases of the genitourinary system;
• hyperprolactinemia;
• taking Cyproterone, Megestrol.

If a reduced level of estradiol is detected during pregnancy, treatment is prescribed, the purpose of which is to normalize the indicators.

Preparing for analysis

Estradiol is considered to be the most active and most “female” hormone. It belongs to the group of estrogens, steroid hormones, along with estriol and estrone.

Estradiol is produced by the ovaries and adrenal cortex. With the onset of pregnancy, the placenta is responsible for its production. Other names of the hormone used in medicine are E2, 17 beta-estradiol, 17 beta-diol, dihydroxyestrin, dihydroxyestratriene, dihydroteelin.

Therefore, quite often you can observe a picture when a doctor prescribes regular tests to determine its amount in the body. You shouldn't be afraid of this. Rather, on the contrary, monitoring concentrations can prevent undesirable consequences - bleeding, threats of pregnancy failure and fetal death.

In order for the result of the analysis to be informative and reliable, you should prepare for it correctly. First of all, you need to be in a positive mood and not be nervous.

It is best to take blood samples in the first half of the day, preferably on an empty stomach. A few days before the test, you should avoid fatty foods, alcohol and cigarettes. It is also not recommended to have sex.

Peculiarities

Estradiol is the most active female sex hormone , which is responsible for reproductive function and many vital processes. It belongs to the group of estrogens, or steroid hormones.

The ovaries and adrenal cortex are responsible for the production of estradiol. A small amount of the hormone is also synthesized by the testicles in the male body.

The hormone affects the functioning of all organs of the reproductive system and takes part in the regulation of the menstrual cycle. During pregnancy, the concentration of estradiol increases greatly, because now its task is to ensure the normal course of this process.
