What concentration of estradiol in women is considered normal. The level of normal estradiol in women

The hormone estradiol has a significant effect on the female body. It is with his direct participation in women that the entire reproductive system is formed, as well as internal organs that are responsible for the reproductive function of the body. In addition, estradiol affects the appearance of women, endowing them with signs that distinguish them from men: it forms rounded outlines of the figure, breasts, deposits of subcutaneous fat on the hips and abdomen.

It is not surprising that in women, a low level of estradiol is not only negatively reflected in appearance, but also in temperament, menstrual cycle, and, most importantly, in the ability to get pregnant: below normal levels often indicate infertility.

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 a small amount - 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, endurance. In addition, he:

• stimulates the maturation of the egg;
• affects the increase in blood flow in the uterus;
• contributes to the thickening of the inner mucous layer of the uterus, the width of which by the time the egg leaves the follicle should be at least a centimeter;
• 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 tissues;
• lowers cholesterol levels;
• has a calming effect on the nervous system.

The amount of estradiol in the blood is unstable and fluctuates constantly. 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 affected by the woman's health, as well as the menstrual cycle: as soon as one of the egg follicles begins to actively grow, and the egg matures in it, it begins to release estrogens, signaling the uterus that it is time to prepare for conception.

By the time the follicle matures in the body, it turns out to be so high that the hypothalamus, one of the parts of the brain, gives a signal to the pituitary gland to increase production, which are responsible for the reproductive system of the body. As a result of a surge, when FSH and LH reach their maximum levels at this moment, the follicle ruptures and the egg that has matured in it comes out, starting to move towards the uterus.

After that, the level of estradiol goes down 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, however, much less than during ovulation and again decreases.

When estradiol is low

The development of many diseases associated with malfunctions of the reproductive system often depends on too low or. In women who do not expect a baby, the hormone norm is:

• follicular phase: 57 to 227 pmol/l;
• preovulatory peak: 127 to 476 pmol/l;
• luteal phase: 77 to 227 pmol/l.

These data are only approximate, since the level of the hormone changes daily, therefore, when donating blood for analysis, you need to tell the specialist what day of the cycle. This will allow more accurate diagnosis of the disease, if any.

Many women may not even know about it until they start planning a pregnancy: according to doctors, with a reduced amount of this hormone, it is very difficult to get pregnant and also bear a child.

Even if conception occurs, the likelihood of miscarriage is extremely high: estradiol has a huge impact on the formation of the placenta, the condition of the uterus, and blood circulation in the pelvic organs. It is also responsible for blood clotting, reducing bleeding during childbirth.

Among the symptoms that signal that the level of estradiol is below normal, and which you should pay attention to in order to start treatment in a timely manner, there are:

• irregular cycle: frequent delays or too early onset of menstruation;
• pain during menstruation and premenstrual syndrome;
• excessive dryness and burning sensation in the vagina;
• decreased sexual desire;
• loss of strength, impotence, fatigue;
• pressure surges, migraines;
• a sharp decrease in body weight;
• frequent sprains and fractures.

In the future, signs develop that a woman is no longer able to ignore. This is a male-type figure change, when the hips narrow, the shoulders become wider, a mustache appears, and the hair on the chin darkens. The situation is also alarming when a woman cannot become pregnant for a long time when trying to do this.

Reasons for lowering the hormone

Various reasons can affect the decrease in estradiol in women. Low levels are always observed during or after menopause. In this case, this is a natural process laid down by nature, when the amount of estrogen decreases and remains at a very low level.

In women of reproductive age, a decrease in estradiol may be associated with the following diseases:

• Hypogonadism - failures in the functioning of the female genital organs and mammary glands, as a result of which they atrophy. The cause of the disease can be genetic pathology, ovarian hypoplasia, radiation, inflammatory processes, tumors of the pituitary gland or hypothalamus, etc.;
• - the disease is characterized by a delay in linear growth (dwarfism) and physical development, which was provoked by poor functioning of the pituitary gland and weak production of hormones;
• Hyperprolactinemia is an increased content of the hormone prolactin in the blood, which during lactation is responsible for the production of milk and delays the onset of a new pregnancy. If a high amount of prolactin is not associated with a baby, tumors of the pituitary or hypothalamus, hypothyroidism, cirrhosis, kidney failure, abortion, chest surgery affect the increase in the hormone;
• Insufficiency of the luteal phase - a decrease in the production of progesterone by the corpus luteum;
• Viril syndrome - the appearance in women of secondary sexual characteristics due to an excess amount of androgens and atrophy of the female genital organs. It is often the result of a tumor of the pituitary gland, hypothalamus, adrenal glands, ovaries;
• Shereshevsky-Turner syndrome is a genetic disease provoked by a violation in the structure of the X chromosome, which is accompanied by pathologies in the development of internal organs and short stature;
• Inflammatory processes of the internal genital organs;
• The possibility of a miscarriage.

Also, a low level of estradiol can be caused by smoking, alcohol, and even taking them in small quantities can cause a sharp decrease in estrogen. It affects its quantity and the desire of women to lose weight when, after many hours of training, upon returning home, they reinforce their strength with an unbalanced diet, for example, empty buckwheat and low-fat kefir.

It is also a generally accepted fact that in vegetarians compared to women who eat meat, the level of reduced estradiol is much more common.

Another reason that can provoke a drop in the hormone is taking medications without the consent of a doctor: many antibiotics, corticosteroids, and hormonal preparations contain substances that affect estrogens. Contraceptives are also dangerous if they are used without consulting a gynecologist: later this may result in the inability to become pregnant.

Solution

If the tests show a reduced amount of estrogen in order to increase the level of estradiol, the doctor will usually prescribe medications that contain this hormone. Such drugs not only restore the menstrual cycle, but also successfully cope with many diseases that provoked low estrogen levels. This is polycystic ovaries, infertility, is used for birth weakness, post-term pregnancy, to reduce the level of prolactin.

If an ailment is detected that drugs containing estradiol cannot cope with, treatment is prescribed to combat the disease. Especially the case does not tolerate delay if a cancerous tumor is detected, the actions of the doctor in this case largely depend on the disease and the course of the disease.

In addition to taking medications, in order to increase the level of estradiol in the body, you need to eat protein foods. The diet may include lean meat, fish, poultry, eggs, liver, dairy and sour-milk products, if there are no contraindications. It is undesirable to get involved in carbohydrates, as well as foods that contain a lot of starch: cereals, pasta, bread, potatoes, beets. It is better to cook food for a couple, boil or stew, it is better to refuse fried foods to increase estradiol.

The female hormonal background changes not only throughout life: during puberty, during pregnancy, during menopause.

One of the most important hormones that affects the health and appearance of women is called estradiol.

He is responsible for a number of processes occurring in the body of the fair sex, and forms signs that distinguish them from men. What does low estradiol in women indicate, and how to restore normal hormonal levels?

Estradiol belongs to the group of estrogens and is the most active sex hormone. Most of it is synthesized by the ovaries, and a small amount is produced by the adrenal glands. In the body of a woman, the hormone is responsible for the following functions:

• the formation of reproductive organs, secondary sexual characteristics and the normalization of the menstrual cycle;
• preparation of the uterus for bearing a child: activation of blood flow, expansion of the vessels of the mucous membrane, thickening of the endometrium;
• improvement of blood clotting;
• strengthening of the vascular walls;
• the formation of bone tissue (mainly tubular bones);
• normalization of the balance of sodium and water, cholesterol levels;
• regulation of metabolic processes in bones and muscles, sexual desire and libido.

In addition, estradiol affects the condition of the skin, hair and nails, the psycho-emotional background of a woman, physical activity and endurance.

In the male body, estradiol is also present - it is produced by the testes, adrenal cortex and peripheral tissues, but in much smaller quantities than in women.

The concentration of estradiol in the female body is constantly changing - depending on the phase of the menstrual cycle and the time of day, and the highest concentration of the substance is observed in the blood of pregnant women. The peak of hormone production occurs during the daytime (three to six hours of the day), after which the indicators decrease.

Estradiol and cycle phases

• the first phase of the menstrual cycle - 12.5-350 pg / ml;
• the period before ovulation - 86-750 pg / ml;
• the second phase - 30-450 pg / ml.

The maximum level of estradiol is observed at the time of maturation of the follicle, as a result of which the production of other hormones increases. A surge in hormonal activity leads to the rupture of the follicle and the release of the egg, which begins to move towards the uterus.

Upon the onset of conception, the concentration of estradiol in the second phase gradually increases, and subsequently its level depends on the duration and characteristics of the course of pregnancy. In the second trimester, the function of hormone production is taken over not only by the adrenal glands and ovaries, but also by the placenta, and a decrease in estradiol levels is observed about a week before delivery.

To check the level of the hormone in the body, a woman is recommended to take an analysis - blood from a vein.

The optimal time for taking a biomaterial sample is the 2nd-3rd day of the cycle; to obtain a complete picture, the study is repeated on the 20th day.

Blood is taken on an empty stomach, a few days before the procedure it is necessary to exclude heavy physical exertion, smoking and alcohol, if possible, stop taking medications.

The reference values ​​​​(norms) of estradiol in a blood sample during the test can differ significantly from each other in different medical institutions, therefore, only a doctor can draw conclusions about an increase or decrease in its concentration.

Some diseases lead to an increase in estradiol in women. If, this may indicate the presence of diseases such as ovarian cysts, cirrhosis of the liver, and even tumors of the hormonal sphere.

The substance estradiol valerate is used in hormonal preparations, in particular, in oral contraceptives. You can read about the main purpose of such drugs.

Low estradiol in women - causes

A decrease in the level of estradiol affects the work of the whole organism, and may be the result of hereditary or acquired diseases, improper lifestyle or living conditions. The most likely causes of this condition include:

• hormonal disorders and dysfunctions of the reproductive system;
• endocrine disorders mainly associated with the activity of the pituitary gland (for example, dwarfism);
• delayed physical and sexual development;
• inflammatory processes of the pelvic organs;
• uncontrolled intake of oral contraceptives;
• unbalanced diet (high-carbohydrate diets without fat, vegetarianism);
• heavy physical activity;
• smoking, alcoholism;
• treatment with chemotherapy drugs.

In the absence of diseases and pathologies, a decrease in the level of estradiol is most often observed in women who are actively involved in sports and at the same time are fond of strict diets or vegetarianism.

Symptoms in women

Since estradiol is often called the hormone of beauty and femininity, a violation of its production primarily affects the appearance, activity and emotional state. You can suspect a decrease in the level of the hormone by the following signs:

• dry skin, the appearance of black spots and rashes;
• hair loss, brittle nails;
• male-type hair growth - the appearance of vegetation on the chin, upper lip, chest, lowering the timbre of the voice;
• swelling and hypothermia (feeling cold) of the hands and feet;
• violation of the monthly cycle, the absence of menstruation for six months or more;
• pain in the mammary glands;
• a decrease in the size of the breast and uterus, a change in the contours of the figure (shoulders become wide, and hips become narrow);
• decreased libido;
• frequent bone fractures, osteoporosis;
• psychoemotional disorders, insomnia, depression.

One of the characteristic signs of low estradiol is infertility. Numerous unsuccessful attempts to get pregnant are a good reason to check the hormonal balance, including the level of estradiol.

A decrease in the concentration of estradiol in pregnant women can entail a serious danger (especially in the second or third trimester) - as a rule, it indicates violations during pregnancy, the threat of miscarriage or premature birth.

Solution

Treatment of hormonal imbalance with a decrease in the level of estradiol depends on the cause of the pathology and concomitant diseases. To normalize the production of the hormone, first of all, it is necessary to give up bad habits, eat right and lead a healthy lifestyle.

A natural way to increase the level of estradiol is by eating foods that contain this substance: dairy, bran, legumes, nuts, flaxseed, soy.

In addition, the hormone is found in some medicinal plants - these include sage, hops, chamomile, linden, licorice.

Tinctures and decoctions are prepared from herbs, after which they are taken according to a certain scheme.

It is categorically not recommended to take any hormone-containing products on your own, even if at first glance they seem harmless - it is necessary to consult a doctor before use.

If it is not possible to normalize the concentration of estradiol with the help of folk remedies, the doctor prescribes hormone therapy. Preparations containing this substance ("Estrofem", "Estraderm") are used for systemic menstrual disorders, polycystosis and other diseases of the reproductive function. In parallel with taking medications, in some cases it is necessary to treat the underlying disease - for example, in case of tumor processes in the ovaries (especially if they are malignant tumors), a surgical operation is prescribed.

In infertility, a low level of estradiol is often an indication for in vitro fertilization (IVF), especially if conservative therapy is ineffective.

The woman is stimulated with ovarian function, after which the resulting egg is fertilized and placed in the uterus.

A certain amount of estrogen in the blood of a man is necessary to maintain the functioning of the cardiovascular system, increase bone density. However, if, this can lead to a decrease in sexual desire, muscle weakness and other abnormalities.

A low level of estradiol can have a negative impact on the appearance and reproductive function of a woman, so when the first signs of such a condition appear, you should immediately consult a doctor. The normal balance of hormones in the body is the key to women's health, youth and beauty.

There are several types of hormones in the female body. Hormones of different types are balanced in the body. When their balance is distorted, this signals either the onset of a disease, or a pathology that has already appeared. An example of a violation of the concentration of hormones can serve as diseases caused by an increase in estradiol.

Estradiol: description, meaning and functions of the hormone

It produces some female hormones, they further control the production of follicle-stimulating and.

Other hormones appear in, they make up a group of steroids. This group consists of substances of the estrogen series and. The estrogen series is represented by three estrogens. The strength of their influence on the female body is not the same. The most powerful sex hormone is estradiol.

Estradiol is responsible for the following tasks in a woman's body:

• manifestation of minor signs of sex (higher than in men, voice, rounded line of the hips and others)
• menstrual cycle control
• egg cell formation
• growth in the size of the uterus as the fetus grows during pregnancy
• creating a layer of subcutaneous tissue
• maintaining normal
• development
• establishment and maturation of the reproductive system
• elimination of excess
• stimulation of bone renewal
• strengthening the muscles of the heart
• maintaining normal
• responsible for sound restful sleep

All of the above allows us to call estradiol one of the main sex hormones in a woman's body. After all, it is he who is not only responsible for the attractiveness of a woman, but also controls health. An imbalance of estradiol in the female body leads to the development of certain diseases.

Diagnosis of the level of estradiol

The best way to identify abnormalities when it comes to the level of estradiol in the female body is.

In the course of a laboratory study of blood taken for analysis, the amount of this hormone in a woman is determined. To get a true and accurate result, you should carefully prepare yourself for the blood donation procedure.

You must adhere to the following rules before doing the analysis:

1. You need to take the test in the morning, preferably from 8 to 11 hours. If, in addition, blood is donated during the luteal phase of the menstruation cycle, then the result will be more accurate.
2. It is worth eliminating or at least lightening the power loads.
3. You need to quit smoking.
4. Try not to overwork.
5. Avoid drinking alcohol.
6. Abstain from sexual intercourse for a while.

A blood test to determine the level of estradiol is taken on an empty stomach. Food before analysis can be taken no later than 8-10 hours.

The ideal option is considered if the level of estradiol corresponds to the level in the female body.But the amount of estradiol varies. Its level is influenced by various factors:

• The number of years of the woman.
• Pregnancy or its absence.
• period of the menstrual cycle.

The greatest amount of estradiol is observed when there are several days before ovulation. After it, the level of estradiol decreases.

The amount of estradiol will increase during pregnancy (210 - 27,000 pg / ml). By the beginning of childbirth, its content will reach its limit, but after childbirth it will noticeably decrease.

Estradiol, contained in the female body on the first day of menstruation in the amount of 57-227 pg / ml, is considered the norm. The norm is the level of this hormone on the eve of ovulation, if the indicator varies from 127 pg / ml to 476 pg / ml. The luteal phase of the menstrual cycle is characterized by a decrease in the level of the hormone to 77-227 pg / ml.

At the time of puberty, there is an increase in the amount of the hormone, which will decrease with age. During menopause, the norm is the content of estradiol 19.7-82 pg / ml.

Reasons for increasing estradiol

A large amount of estradiol is considered normal only during pregnancy. In other cases, high estradiol in women indicates a pathology.

An increase in the content of estradiol is provoked by the following pathologies:

• , other hepatic diseases
• obese
• endocrine syndrome caused by excessive production of thyroid hormones
• increased production of female sex hormones in the skin
• drinking large amounts of alcohol (even beer)
• tumors or
• thyroid disease
• too fast weight loss
• tumors
• long-term use of medications (drugs that prevent seizures, eliminate fungi, anabolic steroids, hormonal contraceptives)

Symptoms of high estradiol in women

The changes that begin to appear in connection with an increase in estradiol in the female body are not specific. Such changes can accompany completely different diseases.

Nevertheless, the symptoms of high estradiol in women include:

• constant fatigue
• sleep disorders
• sudden weight gain
• excessive fatigue
• very dry skin
• hair loss
• low temperature of hands and feet
• uncontrollable irritability
• swelling that was previously absent
• acne that has not previously been observed
• a change in the size of the uterus to a smaller side
• the appearance of pain in the area
• inability to get pregnant
• cessation of menstruation
• increased perspiration
• sometimes there may be bleeding in the uterus
• sudden changes in mood for no reason
• a change in the size of the mammary glands to a smaller side
• pathology in activity and

Since a high level of estradiol can lead to serious complications and disturbances in the activity of some organs, if several of the above signs appear, you should immediately consult a doctor.

Complications to which an increase in estradiol leads

Infertility is one of the most dangerous complications when changing the level of estradiol in women.

Hormonal imbalance (whether the level of estradiol is elevated or lowered) is not normal for the female body. The imbalance poses a serious threat to a woman's health.

If the elevated content of estradiol is observed for a sufficiently long time, then this can lead to a malfunction of the body. In addition, complications may develop:

1. Depressed, depressed state.
2. Bleeding in the uterus.
3. Anemia that takes on a chronic form due to blood loss.
4. Tumors on the ovaries that are malignant in nature.
5. The inability to get pregnant, may develop over time.

So that serious complications do not threaten the health of a woman, it is worth carrying out certain therapeutic manipulations that will help restore hormonal balance. But first, an analysis is required that will show the amount of estradiol in the body.

How to be treated if estradiol is elevated?

To solve female hormonal problems associated with an increase in estradiol, several specialists can help at once: an endocrinologist, a gynecologist, doctors of other, narrower profiles.

But still, you should first come to an appointment with a gynecologist and report those signs that cause concern. After all, high estradiol in women is really a serious reason to worry about your own health.

The course of treatment, if the level of estradiol is elevated, will be prescribed by the doctor individually. In each individual case, quite a lot of factors must be taken into account: the age of the woman, general health, the degree of hormonal imbalance, the presence or absence of complicating moments.

Treatment for elevated estradiol involves the following methods:

• method of treatment based on the use of medicinal plants and complex preparations from them
• proper nutrition
• a set of physical exercises
• physiotherapy
• hormonal treatment

That is, if there are no complications yet, then excess estradiol from the woman's body can be removed without resorting to medication. Let us dwell in more detail on some methods of dealing with elevated estradiol.

It is necessary to normalize the activity of the stomach and intestines, because it is the intestine that removes excess estradiol from the body.

To this end, it is worth consuming vegetable fiber and food containing lingans every day. Flax seeds, bran, greens, hercules, Jerusalem artichoke contain the necessary components. They help reduce the absorption of the hormone from the intestines.

Useful form - Female sex hormones:

To lower estradiol, you need to reduce carbohydrate intake and try to eat foods rich in proteins and omega-3 fatty acids. These components are found in meat, fish products, eggs. Protein is needed to normalize activity and eliminate excess estradiol. Carbohydrates, on the other hand, will supply lingans and fiber, provided they are ingested along with vegetable and fruit products.

A set of physical exercises will help reduce weight.Alfalfa, clover, licorice root, legumes contain phytoestrogens. Their use will reduce the production of estradiol.

Estradiol (E2) is a hormone produced by the ovaries and adrenal cortex, as well as the fetal site during pregnancy. The main role of estradiol is to maintain the stability of menstrual and sexual functions. Since the norm of estradiol in women is a variable value, in this topic we want to tell in detail what level of this hormone is considered normal and what affects it.

Estradiol is extremely necessary for women for the normal functioning of both the reproductive system and the whole organism. For example, estradiol helps to activate the contractile function of the myocardium, strengthen the vascular walls and lower the level of cholesterol in the blood.

Also, this hormone increases the tone of smooth muscle fibers of the intestinal wall and bladder, which improves the functioning of these organs.

In addition to smooth muscles, estradiol has a positive effect on the activity of skeletal muscles, contributing to their regular contraction and relaxation. Thus, the endurance and resistance to stress of the human body increases, and the body becomes elastic.

Estradiol is rightly called the hormone of good mood, because thanks to it we have positive emotions. Depressive states are often observed in persons with estradiol below normal.

In addition to a good mood, estradiol helps women to be beautiful and sexy. This is due to the fact that this hormone allows secondary sexual characteristics to appear, such as rounded breasts, steep hips, thin waist, smooth skin, soft voice, etc. Estradiol is also significant in the formation of libido.

In the process of numerous medical studies, it has been proven that estradiol helps maintain a toned body shape and body weight. For example, in menopausal women, as a result of a decrease in the level of estradiol in the blood, the problem of overweight and bone fragility often arises.

Estradiol plays an important role in creating favorable conditions for fertilization, loosening the endometrium so that successful implantation of the zygote occurs.

Estradiol and the menstrual cycle: the relationship

Estradiol is synthesized and released into the blood throughout the entire monthly cycle, only in different quantities. Its synthesis occurs in the ovaries, adrenal cortex and adipose tissue, during pregnancy - in the fetal site.

During the follicular phase of the monthly cycle, estradiol is produced in a minimal amount, under the influence of follicle-stimulating and luteinizing hormones. Before the ovulatory phase, the amount of the hormone increases three times, after which it decreases, reaching a minimum level before menstruation.

Estradiol during the monthly cycle can turn into estrone and estriol.

Also, the level of estradiol in women changes every hour of the day. The greatest amount of the hormone is synthesized between 15 and 18 hours of the day, and the smallest - between 24 and 2 hours of the night.

Factors affecting the level of estradiol in the body

Once again, I would like to say that the norms of the hormone estradiol in women can change under the influence of various factors, namely:

• phase of the menstrual cycle;
• age;
• pregnancy;
• changing climatic conditions;
• body weight fluctuation;
• harmful environmental factors
• psycho-emotional shock;
• bad habits (alcohol abuse, smoking);
• taking medications.

Each of these facts, as a rule, causes fluctuations in the level of estradiol in the blood within the acceptable range.

In a blood test, the level of this hormone is usually displayed in picograms per milliliter (pc / ml), but this indicator can also be expressed in picomoles per liter (pmol / l).

A blood test for estradiol is prescribed by specialists in such cases as:

• hormonal failure in the body, as a result of which the monthly cycle was disturbed;
• lack of ovulation;
• infertility;
• disruption of the sex glands;
• periodic uterine bleeding not associated with the menstrual cycle;
• severe manifestations of premenstrual syndrome;
• malfunction of the pituitary gland;
• polycystic ovaries;
• fragility of bone tissue;
• neoplasms of the ovaries;
• neoplasms of the adrenal glands;
• preparation for in vitro fertilization.

Blood for research on estradiol is taken strictly in the period from 4 to 6 days of the menstrual cycle. The control analysis is carried out in the period from 20 to 21 days of the cycle.

In order for the result of a blood test for estradiol to be the most objective, when preparing for the study, it is necessary to adhere to the following recommendations:

• 2-3 days before the study is not recommended to transfer;
• 24 hours before blood sampling, limit physical and mental stress;
• exclude sex for 24 hours;
• 24 hours before blood sampling, it is forbidden to smoke and drink alcohol;
• if you are taking any medications, tell the doctor who ordered the tests. In this case, the question of temporary withdrawal of drugs may be considered, since they may distort the results of the study on estradiol;
• The last meal should be no later than 12 hours before blood sampling. The analysis is carried out strictly on an empty stomach.

The optimal time for blood sampling for research is 8-11 am. Blood is taken from the cubital vein in the amount of 5-10 ml.

Waiting for the result of an estradiol blood test can take three to seven days. In emergency cases, the result can be ready five hours after blood sampling.

Estradiol: the norm in women

Table of norms of estradiol in women by age.

In addition to age, estradiol in the blood is affected by the phases of the menstrual cycle and pregnancy.

The norms of estradiol for the phases of the menstrual cycle are as follows.

1. Follicular phase - from 68 to 1265 pmol / l.
2. Ovulatory phase - from 130 to 1657 pmol / l.
3. The corpus luteum phase is from 90 to 860 pmol / l.

With menopause, the amount of estradiol in the blood is reduced and averages 50 pc / ml.

The rate of estradiol during pregnancy depends on the trimester, namely:

• in the first - from 210 to 6300 pc / ml;
• in the second - from 800 to 19000 pc / ml;
• in the third - from 11800 to 37000 pc / ml.

Estradiol and testosterone: ratio

When evaluating the results of a study on the sex hormonal panel, experts evaluate not only the absolute values ​​​​of the estradiol indicator, but also its ratio with other hormones (prolactin, progesterone, testosterone).

The most significant in assessing women's health is the ratio of estradiol and testosterone, which should normally be 10:1, but also an acceptable ratio of 7:1. That is, the result of hormones in which the level of estradiol is 7-10 times higher than testosterone testifies to the normal activity of the female body.

In cases where the level of estradiol is only five times higher than testosterone or less, then such a condition is called hyperandrogenemia in medicine.

Symptoms of hyperandrogenemia may include:

• violation of the menstrual cycle;
• acne
• unreasonable weight gain;
• change in voice timbre from high to low.

They also distinguish a condition such as hypoandrogenemia, when the level of estradiol is much higher than testosterone (12 times or more). Hypoadrogenemia is characterized by the following symptoms:

• severity of manifestations of premenstrual syndrome;
• profuse menstruation;
• irritability;
• the appearance of spotting in the middle of the cycle.

The most dangerous consequence of hyperandrogenemia is diabetes mellitus, and hypoandrogenemia - tumors of the ovaries and uterus.

Estradiol during pregnancy

Once again, we note that the level of estradiol during pregnancy is higher than in non-pregnant women.

In the early stages of pregnancy, the amount of estradiol in the blood of the expectant mother corresponds to normal levels, but in the process of increasing the uterus, it gradually increases.

The highest rate of this hormone is observed in the third trimester of pregnancy. After 5-6 days after birth, the level of estradiol gradually returns to normal.

The role of estradiol during pregnancy is that it contributes to the normal development of the fetus and prevents miscarriage or premature birth. Also, this hormone strengthens the walls of the blood vessels of the birth canal to avoid ruptures during childbirth.

Estradiol with menopause

Menopause in women occurs at the age of 45-55 years, although it happens earlier.

With menopause in women, there is a decline in reproductive function and a decrease in the level of estrogens, in particular estradiol, which is manifested by violations of the sexual sphere and the functioning of all body systems.

Among the menopausal symptoms, the most common are:

• violation of the menstrual cycle with the subsequent cessation of menstruation;
• hot flashes;
• urinary incontinence;
• decrease in sexual desire;
• dryness of the vaginal mucosa;
• emotional lability;
• fragility of the bones.

Also, with menopause, hypertension, atherosclerotic vascular lesions and other diseases of the cardiovascular system may appear.

When evaluating the result of a blood test for estradiol in a woman who is in menopause, the specialist takes into account the following factors:

• how old is the woman;
• what is the duration of menopause;
• the presence of health complaints;
• the presence of diseases of the cardiovascular, nervous, digestive, endocrine and other systems.

With menopause, all women have low levels of estradiol in the blood.

Causes, symptoms and treatment of low estradiol

The most common cause of low estradiol levels is medication, including oral hormonal contraceptives and chemotherapy drugs. Most often, such an adverse reaction occurs with the following drugs:

• Dexamethasone;
• Pravastatin;
• Mifepreston;
• Cimetedine;
• Danazol;
• Nafarelin.

Also, a decrease in the amount of estradiol in the blood can be caused by a high-carbohydrate or low-fat diet, vegetarianism, alcohol abuse and menopause. Among the diseases that most often lead to a decrease in this indicator, it is necessary to highlight polycystic ovaries and chronic inflammatory diseases of the reproductive system.

Symptoms of low estradiol in the blood are as follows:

• acne on the skin of the face;
• dry skin;
• constant feeling of fatigue;
• feeling of coldness in the upper and lower extremities;
• swelling;
• baldness;
• the appearance of hair on the face, chest, abdomen and buttocks;
• failure of the menstrual cycle;
• anovulatory cycle;
• infertility;
• tendency to diarrhea;
• soreness of the mammary glands;
• insomnia or drowsiness;
• irritability;
• decreased sex drive.

The diagnosis and treatment of estradiol deficiency in women is carried out by a gynecologist together with an endocrinologist.

Treatment for low blood estradiol in women of childbearing age is hormone replacement therapy. In this case, Estrofem, Proginova, Estradiol and Estraderm TTS 25 are highly effective.

Self-medication is strictly prohibited, since an inadequate dose or duration of treatment with drugs that contain estradiol threatens with irreversible consequences, such as a complete cessation of the synthesis of this hormone in the body.

In addition to drug therapy, experts recommend sticking to a diet with a predominance of protein foods and intensifying your sex life.

Causes, symptoms and treatment of elevated estradiol

Estradiol above normal is observed during pregnancy. But also high levels of this hormone can be the result of various diseases, namely:

• benign and malignant neoplasms of the ovaries;
• polycystic ovaries;
• hyperthyroidism;
• obesity;
• liver failure;
• chronic alcoholism;
• neoplasms of the mammary glands.

In addition, elevated levels of estradiol are often observed as a side effect of certain medications, including hormonal oral contraceptives, anticonvulsants, and fungicides.

An increase in estradiol in the blood can be suspected by the following signs:

• too short or long periods;
• painful periods;
• acne disease;
• increased sensitivity and soreness of the mammary glands;
• sleep disturbance;
• headache;
• hair loss;
• emotional lability;
• disruption of the intestines.

Treatment is primarily aimed at eliminating the cause, but if the estradiol indicator is not normalized, then hormonal drugs are prescribed. It is also important to normalize the daily routine, get enough rest, protect yourself from stress and eat right.

Estradiol is a female sex hormone. The ovaries and adrenal glands are responsible for its production, and the level varies depending on the stage of the menstrual cycle. This hormone is produced by both men and women. It is estradiol that is important for the formation of the female reproductive system; both the physical and psychological state of a woman depends on it. Today we will talk about this hormone and its significance for the female body.

The hormone estradiol - what is it?

As we said, the level of the hormone in the blood is determined by the phase of the menstrual cycle: at its beginning, the amount of the hormone is high, after ovulation, the body already produces progesterone. But it is estradiol that is responsible for the appropriate development of the egg. The maximum concentration of the hormone leads to the withdrawal of the follicle. In addition, this hormone is involved in the formation of the uterine cavity. What does the condition in which the hormone estradiol is elevated in women mean? More on this below.

With a peak amount of the hormone in the body, a woman is very attractive and sexy. As a rule, this is the moment when ovulation occurs, which is a favorable time for fertilization. During this period, men note that a woman is especially beautiful and desirable, in this regard, estradiol is often called the beauty hormone. With regular production of the hormone in sufficient quantities, a woman has excellent tone, mood and healthy sleep. In addition, thanks to estradiol, wrinkles are smoothed out, normal cholesterol and pressure levels are maintained in the body, and vision is maintained. It is also necessary to start all metabolic processes in the body. If a woman's body for some reason produces an insufficient amount of this hormone, the doctor prescribes a drug that compensates for the lack of the hormone estradiol. What is it, we explained.

More about functions

The main purpose of this hormone in the body is to ensure the growth of the follicle and the development of the functional layer of the epidermis. By the time of ovulation, its thickness should be no more than one centimeter. A small amount of this hormone in the female body leads to the fact that the follicle does not mature, that is, ovulation does not occur. In this case, even if the egg was fertilized, miscarriage most often occurs. This hormone in the form of a medicine is used to treat many pathologies, for example, when ovarian cysts occur. In addition, there is evidence that this hormone is able to cope with cirrhosis of the liver in the initial stage and breast cancer. In certain cases, the hormone can be used as a means of emergency contraception: you need to take it immediately after sexual contact.

In the presence of a lack of estrogens, the hormone must be taken for three weeks, then a break in treatment is made for 1 week and the course is repeated. Maximum such treatment can last six months, after which an examination should be carried out. Once again, I would like to say that it is estradiol that is responsible for the beauty and attractiveness of a woman: thanks to it, feminine proportions, lush breasts, a thin waist and beautiful hips are formed. Eyes shine, mood improves, sexual desire increases. With a normal level of the hormone in the body, women's skin is always velvety and soft. In addition, the presence of estradiol prevents the appearance of hair in places atypical for women: the chin, arms, chest and abdomen. Estradiol provides the full formation of fatty and bone tissues, fiber. It has a positive effect on the functioning of the vessels that are located in the uterus. It retains sodium and fluid in the body, helps reduce tension and irritability. Production in the body occurs mainly between 15.00 and 18.00. The largest amount of the hormone is formed in the female body during pregnancy, after the baby is born, the hormone level gradually returns to normal. Also, the production of the hormone estradiol (which is interesting to many) decreases with age, during the menopause, production approaches male indicators.

Diagnostics

To obtain reliable data, it is enough to take a blood test. In general, it must be taken between 8 and 11 am, at the end of the menstrual cycle. Before this, it is necessary to exclude: overwork, sports, smoking and drinking alcoholic beverages. Do not have sexual intercourse, try not to eat.

What is the norm in women of the hormone estradiol?

Norm and deviation from it

The ideal is the situation in which the amount of female hormone is balanced by the amount of testosterone. But as we know, the level of estradiol is always different and too many factors influence it: age, phase of menstruation, pregnancy. The highest amount of hormones will be immediately before ovulation and during pregnancy. The value can range from 210 to 2700 pg / ml. The hormone will reach its maximum by the time of delivery, after which it will gradually decrease. At the beginning of the cycle, the level of estradiol will vary from 57 to 227 pg / ml. Increased rates are observed in young girls during the period when puberty occurs. By the time a woman begins menopause, these figures are approaching a minimum. The norm of the hormone estradiol in women in menopause may range from zero to 54 pg/mL.

Decreased female hormone levels

A reduced level of estradiol leads to some changes in the female body, which are of great importance when planning a pregnancy. This process is accompanied by irregular menstruation up to their complete disappearance. If the cause of irregular periods is low estradiol, then they will be very painful. In addition, in this case, the woman is subject to severe irritability, nervousness, symptoms of what is commonly called PMS. There is also increased fatigue, headache, changes in blood pressure and weight loss. A decrease in the level of this hormone can also be accompanied by such unpleasant symptoms as hair growth in places that are not typical for women. At the same time, the figure is more and more like a man's with broad shoulders and narrow hips.

The reasons

The reasons that the hormone estradiol is lowered in women can be a number of factors:

• hereditary disorders.
• Leading an unhealthy lifestyle.
• Excessive alcohol consumption and smoking.
• The occurrence of comorbidities.

The level of the female hormone is affected by an unbalanced diet and excessive sports. As well as uncontrolled intake of antibacterial drugs, steroid-type drugs or hormones. This also includes the use of contraceptives that were not prescribed by a doctor.

You also need to take into account the fact that in women with menopause, the hormone estradiol is produced in smaller quantities.

Increasing the level of estradiol

An increased concentration of this hormone is considered the norm only during pregnancy, in all other cases it is a pathology. An increase in the amount of this hormone can be caused by:

• liver diseases;
• obesity;
• dysfunction of the thyroid gland;
• abuse of alcoholic beverages;
• tumors, including a tumor of the mammary gland;
• rapid loss of body weight;
• long-term use of certain medications.

We know what the hormone estradiol is responsible for in women. Changes in this condition cannot be defined as specific, they can occur in many other diseases.

Characteristic features

The characteristic signs of elevated estradiol include:

• constant feeling of tiredness and lethargy;
• insomnia;
• rapid increase in body weight;
• dry skin and baldness;
• feeling of coldness in the legs and arms;
• increased nervousness and irritability;
• the regular appearance of edema, if previously it was not typical;
• acne;
• breast diseases;
• irregular menstruation and lack of pregnancy;
• excessive sweating;
• uterine bleeding;
• sudden mood swings.

Naturally, an increased level of the female hormone can lead to unpleasant consequences in the form of serious diseases, so if you have the slightest suspicion, you should consult a doctor.

What is the solution to the problem?

In order to solve the problem of estradiol imbalance in the body, a woman should contact a gynecologist or endocrinologist. Doctors will prescribe an examination and, based on its results, taking into account all factors (age, degree of hormonal imbalance), will determine the treatment. As a rule, therapy consists of several components:

• physiotherapy exercises;
• proper, healthy nutrition;
• the use of medications and folk remedies;
• hormonal treatment;
• physiotherapy procedures.

It should be remembered that earlier contacting a doctor in this case is very important and allows you to do without medication, only adjusting your diet and leading a healthier lifestyle.
