Despite the fact that testosterone is considered a purely male hormone, it is also present in the female body, while performing slightly different functions than in the stronger sex. In women, it also has its own norms; it can decrease, increase, and depending on changes in its level, various disturbances are observed. In such cases, it is advisable to conduct a testosterone test in women to determine the causes of deviations.

Norm and deviations of free testosterone in the blood in men

The Free Testosterone Index is a formula that calculates free testosterone. It is used in cases where it is not possible to detect free hormone using tests. The free testosterone index is calculated as follows:

  • determine the amount of total testosterone;
  • determine the amount of globulin;
  • calculate the ratio between the first and second indicator.

The result of the calculation will be a figure that determines free testosterone.

The norm for free testosterone in men by age is:

  • age from 18 – 50 years the indicator is 5.76 – 30.43 nmol/l;
  • over 50 years of age the indicator is 5.41 – 19.54 nmol/l.

Non-compliance with the norm indicates a problem in the body. Diseases that appear if free testosterone is low:

  • prostate carcinoma;
  • infertility;
  • diabetes;
  • atherosclerosis;
  • cardiovascular diseases.

Free testosterone decreases under the influence of the following factors:

  • sedentary lifestyle;
  • bad habits that reduce the quality of life;
  • excess weight;
  • genital injury;
  • stress and depression;
  • improper unbalanced diet;
  • aging.

According to established medical standards, free testosterone in women ranges from 0.31 to 3.78 nmol/l.

Throughout life, the rate of free testosterone increases and reaches its maximum level. Free testosterone in women normally has the following values:

  • girls over 18 years old – 0.5 – 4.1 pg/ml;
  • women in menopause – 0.1 – 1.7 pg/ml.

An increase in one value does not necessarily entail an increase in another. For example: an analysis of the level of free hormone showed an exceeded value, but a general blood test for testosterone in women remains unchanged. This indicates liver problems.

Testosterone testing in women during pregnancy, especially in the second and third trimesters, produces free testosterone values ​​significantly higher than normal. This is explained by the fact that in addition to the pregnant woman’s own organs that produce testosterone, the fetal organs provide additional production of the hormone.

In pregnant women, it is difficult to establish the exact range of free hormone, since the hormonal background of each pregnant woman is individual.

About which hormones need to be taken when... Maybe it will be useful for someone)))

To determine the fullness of your hormonal levels, your doctor will most likely order you to donate blood for hormones. Hormones are highly active substances produced by the endocrine glands. Hormones are the main link in the construction and implementation of the reproductive function of women and men. And this happens through the hypothalamus-pituitary-ovarian system. If the functioning of one of the components of the system is disrupted, the entire functioning of the reproductive system changes, and, consequently, the ability to conceive decreases. That is why one of the important criteria for examining a woman is to assess her hormonal levels - determining the concentration of certain hormones in the blood, taking into account the phase of the menstrual cycle. Hormone tests are taken in the morning on an empty stomach. In clinical practice, the following sex hormones are tested and are of importance in connection with infertility. FSH is follicle stimulating hormone. In women, FSH is one of the main hormones that regulates the growth of the follicle (egg) in the ovary and the formation of estrogen, under the influence of which the endometrium grows in the uterus. The maximum level of FSH is found in the middle of the cycle, which leads to ovulation. This hormone is given on days 3-7 (depending on the purpose of the study) of the cycle. To determine the possibility of follicle growth, FSH is given on days 5-8. In men, FSH is the main stimulator of the growth of the seminiferous tubules. FSH increases the concentration of testosterone in the blood, thereby ensuring the process of sperm maturation. This happens when a man's testicles are small or have suffered from some kind of surgery or infection. For men, this is one of the four main sex hormones, the violation of the secretion of which leads to impaired reproductive function (the other three: LH, testosterone and prolactin). LH is the luteinizing hormone. In women, it ensures the completion of the maturation of the egg in the follicle and ovulation. LH also ensures the secretion of estrogen and the formation of the corpus luteum. In a woman’s cycle, the peak concentration of LH occurs at ovulation, after which the level of the hormone drops and “stays” throughout the luteal phase at lower values ​​than in the follicular phase. This is necessary for the functioning of the corpus luteum in the ovary. During pregnancy, LH concentration decreases. Rent in the same way as FSG for 3-8 d.c. In men, by stimulating the formation of sex hormone binding globulin, LH increases the permeability of the seminiferous tubules to testosterone. This increases the concentration of testosterone in the blood, which promotes sperm maturation. One of the quite significant criteria when examining for infertility is the ratio of LH and FSH. Normally, before the onset of menstruation it is 1, a year after the onset of menstruation - from 1 to 1.5, in the period from two years after the onset of menstruation and before menopause - from 1.5 to 2. Prolactin. Prolactin is involved in ovulation and stimulates lactation after childbirth. Therefore, it can suppress the formation of FSH in “needed targets” during pregnancy and in unnecessary ones in its absence. With increased or decreased levels of prolactin in the blood, the follicle may not develop, as a result of which the woman will not ovulate. A change in the concentration of this hormone alone is sufficient to cause infertility. To determine the level of this hormone, it is important to do an analysis in phases 1 and 2 of the menstrual cycle strictly on an empty stomach and only in the morning. Immediately before taking blood, the patient should be at rest for about 30 minutes, since prolactin is a hormone, stress and anxiety or slight physical activity can affect its level. During the luteal phase, prolactin levels are higher than during the follicular phase. An increase in prolactin levels in men can impair the sexual function of Estradiol. Blood is tested for this hormone throughout the entire menstrual cycle. It has a versatile effect on all female genital organs. Its role is especially important in the development of the uterine mucosa and preparing it for pregnancy. This hormone is secreted by the maturing follicle, corpus luteum of the ovary, adrenal glands and even adipose tissue under the influence of FSH, LH and prolactin. In women, estradiol ensures the formation and regulation of menstrual function and the development of the egg. A woman ovulates 24-36 hours after a significant peak in estradiol. After ovulation, the hormone level decreases, and a second, smaller amplitude, rise occurs. Then there is a decline in the concentration of the hormone, which continues until the end of the luteal phase. Progesterone. This hormone is also called the “pregnancy hormone” because it ensures the final preparation of the uterine mucosa for the attachment of the embryo. Progesterone also provides optimal conditions for a developing pregnancy. It is important to check this hormone on days 19-21 of the menstrual cycle. In anovulatory cycles, the result is uninformative. Testosterone. This hormone can be tested in both men and women any day. Testosterone is needed by both spouses, but is a male sex hormone. In the female body, testosterone is secreted by the ovaries and adrenal glands. Exceeding the normal concentration of testosterone in a woman can cause irregular ovulation and early miscarriage, and the maximum concentration of testosterone is determined in the luteal phase and during ovulation. In a man, a decrease in testosterone concentration causes, as is correct, a lack of male strength and a decrease in sperm quality. DEA sulfate is a hormone that is one of the “male” sex hormones, which is normally produced in a woman’s adrenal glands in small quantities. When the concentration of this hormone increases, ovarian dysfunction and infertility often occur. DHEA sulfate hormone can be tested in both men and women on any day. The body of both spouses also needs it, but in different proportions. Thyroid hormones (thyroxine - T 4 and triiodothyronine - T 3) indirectly participate in the regulation of ovarian function. With diseases of the thyroid gland, infertility often develops. Free T3 (free triiodothyronine) is produced by the follicular cells of the thyroid gland under the control of thyroid-stimulating hormone (TSH). It is a precursor to the more active hormone T4, but has its own, although less pronounced, effect than T4. Blood for analysis is taken on an empty stomach on any day of the cycle. Immediately before drawing blood, the patient should be at rest for about 30 minutes. T4 (total thyroxine). This hormone, by increasing the basal metabolic rate, increases heat production and oxygen consumption by all tissues of the body, with the exception of the tissues of the brain, spleen and testicles. Levels of the hormone in men and women normally remain relatively constant throughout life. However, in some areas there is often a decrease in the activity of the thyroid gland, which can lead to serious deviations in one’s own health and the health of the unborn child. TSH (Thyroid Stimulating Hormone) regulates the functioning of the thyroid gland. Changes in its concentration are a marker of thyroid diseases. Available on any day of the cycle.

Summary. Hormones are biologically highly active substances formed in the endocrine glands, entering the blood and exerting a regulatory effect on the functions of organs and systems of the body remote from the place of their secretion. After formation in the endocrine glands, hormones enter the blood as needed, which depends to a certain extent on the time of day and the age of the person. Regulation of a woman’s reproductive function is carried out through the hypothalamus-pituitary-ovarian system with the help of hormones. To determine the completeness of hormonal regulation of the menstrual cycle, tests are carried out to determine the following hormones in the blood serum (strictly by day of the cycle): LH (luteinizing hormone) - on days 3-5 of the cycle. Stimulates follicle maturation, estrogen secretion, ovulation, and formation of the corpus luteum. FSH (follicle stimulating hormone) - on days 3-5 of the cycle. FSH has a trophic effect on the ovary, stimulates the growth, development and maturation of the follicle. Prolactin - on days 3-5 of the cycle. It has a trophic effect on the corpus luteum, transforming it from non-functioning to functioning. Thus, the secretion of progesterone is stimulated. Stimulates lactation and suppresses FSH secretion; for this reason the follicle does not develop. Estradiol - on days 20-21 of the cycle. Secreted by the maturing follicle and adrenal glands. Progesterone - on days 20-21 of the cycle. A hormone produced by the corpus luteum and placenta (during pregnancy). Prepares the endometrium for embryo implantation. Testosterone – on days 8-10 of the cycle. Male sex hormone. In the female body it is secreted by the ovaries and adrenal glands. It is a precursor to estradiol. Exceeding the normal concentration can cause early miscarriage. 17-OH progesterone - on days 8-10 of the cycle. Precursor of sex steroid hormones. The main source is the adrenal glands. DEA - sulfate - on days 8-10 of the cycle. The main source is the adrenal glands. Sex hormone binding protein (SHBG, transport protein) - on days 8-10 of the cycle. Binds androgens in the blood serum, leaving only a small part of them in an active state. Antisperm antibodies are antibodies to sperm. They can form both in the blood of a woman and in the blood of a man (an autoimmune reaction to sperm). Available on any day of the cycle. Conditions for hormone analysis: Fasting. By days of the cycle (as prescribed by the doctor). General recommendations for hormonal examination: LH, FSH, Prolactin - on days 3-5 of the cycle Testosterone, 17-OH-progesterone, DHEA sulfate, SHBG - on days 8-10 of the cycle. Estradiol, Progesterone - on days 19-21.

What is testosterone responsible for in the female body?

The importance of this hormone for the male body cannot be underestimated. Its functions include vital tasks:

  • puberty;
  • full formation of the testicles, prostate and penis;
  • hair growth on the pubic area and in the armpits;
  • protein formation in tissues;
  • positive effect on the brain;
  • ensuring normal healthy erection;
  • lowering cholesterol levels.

The hormone of male happiness has a great influence on sexual activity. An overestimated blood level indicates a strong attraction to the fairer sex. Over time and for certain reasons, libido may decrease.

A man needs to know how to maintain his masculine dignity and maintain testosterone levels within the established norm. First you need to analyze the circumstances that influence the decrease in sexual desire:

  • frequent tension, depressed state;
  • hormonal imbalance;
  • diseases of the genitourinary system;
  • mature age of a man after 50 years.

The first step is to get rid of stress and depression. It is the psychological state of a man that has a great influence on the decrease in libido.

Testosterone is produced in the ovarian follicles, in the adrenal tissue, and also in small amounts in the liver parenchyma. This hormone in the female body is a precursor of estrogens, which ensure the growth and maturation of the egg, the development of mammary gland tissue and the formation of a female body type. In addition, in a woman’s body testosterone is responsible for other functions:

  • Normalizes the secretion of sebaceous glands and maintains skin elasticity.
  • Ensures normal hair and nail growth.
  • Affects the hematopoietic activity of the bone marrow.
  • Provides skeletal strength – bone development and mineral metabolism.
  • Growth and maintenance of muscle mass.
  • Maintains a stable psycho-emotional state - resistance to stress.
  • Supports libido.

Hormone levels can vary depending on the age and condition of a healthy woman. During the period of ovulation, testosterone levels are at their maximum and provide increased sexual activity.

During pregnancy, the hormone content gradually increases and reaches maximum values ​​in the third trimester. This ensures the growth and development of the fetal skeleton and its hematopoietic system.

During menopause, there is a natural decrease in testosterone production in a woman's body. It is during this period of life that women are more susceptible to mood swings, their libido decreases and the risk of developing osteoporosis increases.

In women, under the control of the pituitary gland, testosterone is synthesized in two main organs: the adrenal glands and the ovaries. This hormone is produced in small proportions by the adrenal glands and supplements the overall level. The bulk of testosterone is produced by the ovaries and released into the blood.

Once in the blood, testosterone performs many functions:

  • it affects metabolism and controls the amount of fat deposited;
  • the hormone helps build muscle mass;
  • affects the activity of the sebaceous glands;
  • promotes proper growth and formation of mammary glands;
  • regulates the level of a woman’s sexual activity (with a large amount of testosterone, a woman is hypersexual, and with a low level, on the contrary, she does not feel the need for sex);
  • testosterone, like any other sex hormone, affects psychological well-being in adulthood, helping to remain feminine in any situation. To feel fragile, desired and in demand. An increase in normal levels of the hormone in the blood increases a woman's activity, making her aggressive and exhibiting unhealthy control over people and situations. Too low a hormone content, on the contrary, causes passive behavior, apathy towards everything and excessive calmness.
  • Testosterone in women (normal if it is contained in a small volume in the blood) is actively involved in the absorption of a number of substances, including those responsible for the normal formation of bone tissue.
  • It regulates the degree of attractiveness to the opposite sex.
  • Testosterone affects the functioning of the genital organs in women. It promotes the correct and timely production of eggs and the corpus luteum.
  • This sex hormone also normalizes the functioning of all internal organs, which increases tone and improves mood. But such an effect occurs only when there is a sufficient level of the hormone in the blood.

Why should a woman get tested for testosterone?

Doctors do not always prescribe tests for testosterone for men; there are a number of reasons why a woman can also be prescribed tests for this type of hormone. Despite the fact that testosterone is male, it is always present in the female body. It is he who contributes to the emergence in women of such qualities as courage and sexual desire.

There are many reasons that can have a negative impact on testosterone. But more often the reason for its deviation from the norm is the exclusion of certain foods from the diet. For example, many vegetarians, due to the exclusion of protein foods from the diet, experience an increase in muscle mass and other symptoms indicating increased testosterone in the body. Symptoms indicating disturbances in the concentration of the hormone may appear in the form of:

  • Decreased sexual desire;
  • Failure of the menstrual cycle. In this situation, when testing blood for testosterone, the level of concentration of other hormones is also determined;
  • Deterioration of the condition of nails and hair;
  • Obesity;
  • Sleepy, tearful state, chronic fatigue;
  • Osteoporosis;
  • Infertility;
  • Acne;
  • Baldness;
  • Increased hair growth occurring in different parts of the body;
  • Neoplasms in the uterus;
  • Tumors in the ovaries;
  • Male forms.

It is worth knowing that disruptions in the production of male hormones in women can be caused by a hereditary predisposition.

Even with a slight deviation from the norm, testosterone in a woman’s body can provoke serious changes. Therefore, it is advisable for every woman to take a testosterone test once every certain period. Such monitoring of hormone levels will allow timely detection of any changes and timely implementation of the required treatment.

Disorders of testosterone production in women

A doctor may prescribe a testosterone test for a woman if she has symptoms such as:

  • disruption of the menstrual cycle;
  • hirsutism;
  • decreased libido;
  • deterioration of hair and nails;
  • rapid weight gain;
  • sudden mood swings;
  • difficulty conceiving;
  • acne on the face and body.

The study can be included in the list of tests if any gynecological disease is suspected. A woman may also be prescribed this type of study during pregnancy.

A laboratory test of the blood that patients donate for the hormone determines the level of free and total testosterone. The general indicator will indicate what concentration of the hormone is contained in the woman’s biological material at the time of donation. Free - active free fraction of testosterone. It does not bind to other proteins.

If testosterone is given on the 5th day of the cycle, the norm for women of reproductive age is considered to be:

  • free testosterone - less than 4.1 pg/ml;
  • total testosterone - 0.38 - 1.97 nmol/l.
Woman's ageMinimum values, nmol/lMaximum values, nmol/l
Newborns2,31
1-6 years1,22
11-150,491,82
15-181,364,73
Over 18 years old:
follicular phase (days 1-7 of the menstrual cycle)0,453,75
ovulation0,462,48
luteal phase0,311,73
40-59 years old0,132,6
Menopause (over 60 years)0,131,8

When the interpretation of the results indicates deviations from the norm, the doctor may prescribe additional tests and examinations. They are necessary in order to find out what caused such changes in the female body. After collecting all the necessary information about the patient, a diagnosis will be made and appropriate treatment will be prescribed.

Take the time to take the online tests:

Possible reasons for an increase or decrease in hormone levels in the body include:

  • tumor neoplasms in the ovaries;
  • pathologies of the kidneys or adrenal glands;
  • alcoholism;
  • dramatic changes in diet (for example, a strict diet);
  • fibroids or uterine polyposis;
  • oncological processes in the body;
  • taking medications;
  • climatic conditions (change of place of residence);
  • age-related changes, etc.

A slight deviation from the norm does not always indicate the presence of a pathological process. Some women have a genetic predisposition to increased testosterone production. But only a doctor can confirm the safety of this anomaly for the patient.

The root causes of changes in testosterone levels in men can be varied. A blood test for testosterone in men is prescribed based on existing chronic diseases:

  • diabetes mellitus of all types;
  • sexual impotence - lack of erection;
  • obesity of all degrees;
  • acne, dandruff, seborrheic dermatitis;
  • metabolic disorders;
  • disruption of the process of sperm maturation;
  • taking narcotic drugs;
  • acquired or congenital diseases of the pituitary gland, adrenal glands and testicles;
  • drinking alcoholic beverages;
  • living or working in a radiation zone;
  • osteoporosis;
  • testicular dysfunction;
  • baldness and impaired hair growth.

The analysis allows us to identify most disorders associated with the endocrine system.

A blood test for testosterone in women is prescribed in the following situations:

  • recurring uterine bleeding;
  • missing menstruation;
  • ovarian tumor;
  • spontaneous termination of pregnancy;
  • irregular periods;
  • absent ovulation;
  • polycystic ovary syndrome;
  • increase in the menstrual cycle up to 35 days;
  • male-type hair growth on the abdomen and face;
  • uterine fibroid;
  • mastopathy;
  • breast tumor;
  • endometriosis;
  • congenital underdevelopment of the uterus and mammary glands.

If at least one of the listed signs is present, then this is an alarming signal to monitor your blood for testosterone.

Before taking testosterone tests, it is recommended to prepare in advance. Preparation begins approximately a day before the expected blood donation. To obtain more accurate results, it is advisable to adhere to the rules before taking tests. Not allowed:

  • drink drinks containing alcohol, even in minimal doses;
  • perform heavy physical activity, and also exclude sports.
  • eat fatty foods, fried, highly salted and pickled foods;
  • smoking, a prerequisite is to abstain from smoking for at least 4 hours, including the use of hookah;
  • take tonic drinks: coffee, tea, energy drinks, etc.

It is necessary to donate blood for testosterone only on an empty stomach. In this case, the last meal should be completed no later than 12 hours before blood sampling.

The analysis is given strictly at 8-11 am. It is during this time period that the concentration of testosterone in the blood is close to its highest value. On the day of the test, it is preferable to drink plain water without gases.

It is also prohibited to donate blood within 24 hours after radiography, ultrasound diagnostics (ultrasound) and fluorography. Hormonal medications are discontinued approximately two weeks before the test. Your doctor will tell you exactly when to take testosterone.

Hormone tests are always taken on certain days of the cycle. Women are interested in which day of the cycle to take testosterone in order to get the correct test values.

With a stable cycle during the absence of pregnancy, testosterone analysis in women is carried out on days 5-7.

The most commonly prescribed and most common way to determine the level of the hormone in the blood is a general testosterone test. Blood is drawn from the ulnar vein using a disposable syringe. Subsequently, the blood is combined with a medical reagent. The result is a colored solution. The level of hormone content is determined by the intensity of the color.

Testosterone norms in men

What levels of total testosterone are considered normal:

  • men from 19 years to 55 – indicator 1.0 – 28.28 pg/ml;
  • men over 55 years of age - 0.7 - 21.45 pg/ml.

If the results obtained in men are abnormal, the endocrinologist will prescribe an additional blood test for testosterone-binding globulin. Based on the data obtained, he will determine the presence of the disease and select individual and competent therapy.

The level of testosterone in the blood in men and women is determined by several parameters: normal, increased or decreased.

With increased testosterone levels in men, the following types of pathologies may occur:

  • testicular tumor;
  • prostatic hyperplasia;
  • Itsenko-Cushing's disease;
  • the emergence of a desire to assert oneself;
  • increased hostility and aggressiveness can be observed.

With low testosterone levels in men, pathologies such as:

  • hypogonadism;
  • hyperprolactinemia;
  • violation of potency;
  • obesity of all types;
  • chronic prostatitis;
  • adrenal insufficiency.

When testosterone levels are low, men of reproductive age develop infertility. Under the influence of stress and age, men's sexual activity fades away.

An endocrinologist will prescribe an additional examination, where blood will need to be tested to determine the level of free testosterone in the body.

The preparation requirements for passing the analysis are the same as for the general one. Ignoring the rules and violating at least one of the points in the memo will lead to inaccurate results and a blurred clinical picture. You can verify the results yourself.

Women's adrenal glands and ovaries produce less testosterone than men produce. Hence the conclusion that the norms of total testosterone in women differ from those in men. The indicator of total testosterone in a woman’s body indicates the content of the total amount of the hormone in the body.

The normal level of total testosterone in women ranges from 0.26 to 1.30 ng/mol.

Any deviations from the norm in the results of total testosterone indicate a serious illness. If an elevated level is detected, then this threatens a pathological disorder in the formation of the egg. This produces too much male hormone.

Low testosterone is also a pathology, expressed by external and internal manifestations.

Internal reasons include:

  • endocrine diseases;
  • ovarian tumors;
  • adrenal diseases;
  • autoimmune pathology;
  • age-related changes;
  • heredity.

External reasons:

  • poor nutrition;
  • eating foods containing magnesium or zinc;
  • consumption of alcoholic beverages;
  • taking oral contraceptives;
  • low sexual activity;
  • excess body weight.

When the hormone level is reduced, the following accompanying phenomena are observed:

  • depression;
  • obesity in the abdomen, arms and neck;
  • dry skin, brittle nails and brittle hair;
  • impaired concentration;
  • memory loss;
  • lack of libido;
  • excessive sweating;
  • weight loss;
  • insomnia.

Testosterone is called the male hormone, since its content in the body of the stronger sex is much higher. In men, the hormone is produced in the ovaries and is responsible for the appearance of secondary sexual characteristics. The action of testosterone promotes the growth of mustaches and beards, the formation of a male body type (wide shoulders, narrow hips) and a characteristic timbre of the voice.

The main female hormones are estrogen and progesterone. However, the level of testosterone in a woman’s blood plays an important role. In women, testosterone is produced in the ovaries and adrenal glands. The main function of the hormone in the female body is the formation and maturation of the egg. In addition, testosterone ensures the formation of the figure and growth of the mammary glands, controls the functioning of the sebaceous glands, and is involved in the formation of the skeleton and hair growth. Thanks to the action of testosterone, libido increases and the emotional state stabilizes.

A testosterone test must be taken when:

  • unstable menstrual cycle or its sudden disruption;
  • deterioration of hair and nails;
  • increased hair growth on the chest and face;
  • decreased libido;
  • inability to conceive a child if there are no other reasons interfering with fertilization;
  • rapid weight gain;
  • pregnancy planning;
  • presence of gynecological diseases;
  • unstable emotional state;
  • the appearance of acne.

Testosterone levels vary depending on the day of the menstrual cycle and the individual characteristics of the body. During pregnancy, there is an increase in the hormone in the third trimester. This is due to the fact that testosterone is necessary for the formation of a strong skeleton of the fetus and its proper development.

A laboratory test of the blood that patients donate for the hormone determines the level of free and total testosterone. The general indicator will indicate what concentration of the hormone is contained in the woman’s biological material at the time of donation. Free - active free fraction of testosterone. It does not bind to other proteins.

If testosterone is given on the 5th day of the cycle, the norm for women of reproductive age is considered to be:

Normal and abnormalities of total testosterone in the blood in men

In pregnant women, testosterone is actively produced by the placenta for the normal formation of the fetus. In older women during menopause, the amount of testosterone in the blood increases. And then gradually decreases as reproductive capacity disappears.

Testosterone in women (its normal amount is present in the blood starting from birth) consists of a biologically active fraction (no more than 2%) and 98% of the hormone itself, bound by individual proteins. The hormone itself is measured in nmol/l, and its amount depends on the woman’s age and health status.

Testosterone levels in a healthy body tend to fall and show the lower levels of normal. From 30 to 50 years, the concentration of the sex hormone can vary greatly in values.

For example, it increases during the period of ovulation in a woman. The worst effect on health is increased hormonal levels, which can cause various diseases and even cause death. Thus, a hormone level of 15 nmol/l poses a threat to the lives of elderly women.

First of all, these are natural reasons, such as:

  • the period of pregnancy during which testosterone production increases 4 times. This is due to additional active production of the hormone by the placenta. Moreover, if a boy is to be born;
  • the period of menopause, when, for natural reasons, the ovaries stop actively working and hormone production is greatly reduced;

    Testosterone levels decrease in women during menopause

  • Testosterone also increases during the period of ovulation, which increases female attractiveness naturally;
  • hereditary predisposition to increased testosterone levels.

Changes in hormone levels are greatly influenced by lifestyle and certain habits:

  • A strict diet with a limited amount of quickly digestible carbohydrates significantly reduces testosterone levels;
  • smoking and alcohol contribute to an uncontrolled increase or decrease in hormone production;
  • vitamin deficiency (lack of vitamins) often causes disorders associated with insufficient hormone production;
  • a sedentary standard of living and lack of systematic sports training affects changes in hormonal balance, as well as obesity;
  • long abstinence or lack of full sexual life contribute to an increase in hormone levels;
  • Failure to produce hormones in normal quantities occurs after prolonged use of medications. In particular, the amount of testosterone is strongly influenced by oral contraceptives containing estrogen-progestogen.

Often changes in testosterone levels are associated with diseases.

These include:

  • diseases of the uterus (endometriosis);
  • adrenal insufficiency;
  • pituitary adenoma;
  • the postoperative period during removal of the ovaries, when testosterone levels also decrease and in this case hormonal therapy is prescribed;
  • dysfunction or hyperfunction of the adrenal cortex, in which the release of the hormone occurs uncontrollably;
  • breast cancer, cysts and ovarian tumors.

Causes difficulties in physical development, namely in the correct formation of the skeleton and muscle mass. Unbalanced hormone production affects the deposition of fat, the development of obesity and the size and beauty of the breasts during their formation.

Also, a reduced amount of the hormone, as well as its significant increase compared to the norm, provokes disturbances in the menstrual cycle, difficulties with conception, even infertility.

In women, elevated testosterone levels, as opposed to normal levels, cause the appearance of male characteristics (for example, increased male-pattern hair growth). Along with physical manifestations, a woman’s character changes, rudeness and mood swings appear, which negatively affects loved ones.

A woman's testosterone test results change daily. This feature is considered normal; it depends on the day of the menstrual cycle. In pregnant women, an increase or decrease in hormone levels is associated with gestation.

In most cases, women are tested for testosterone in the morning, because... At this time, its highest concentration in the blood is observed. 12 hours before collecting biological material, it is prohibited to eat. It is also better to avoid water, but a small dose is allowed. If a woman cannot completely stop drinking liquids, she is allowed to drink only clean, still water. A woman should take a blood test for testosterone no earlier than 3 days after her last sexual intercourse.

For the sake of clarity, some experts do not recommend brushing your teeth in the morning.

To get the most reliable results, you should adhere to other rules:

  1. Donate blood no earlier than 24 hours after an ultrasound or x-ray examination.
  2. Do not take drugs or alcoholic beverages. Smoking is also included in the list of contraindications.
  3. 1-2 days before the test, you should refrain from fatty, fried and salty foods. The diet should contain only easily digestible foods. But complete refusal of food, i.e. Hunger strike before the study is also prohibited.
  4. In the last 24 hours, it is forbidden to overexert yourself. Intense physical activity affects the amount of testosterone in the blood. You should stop working out in the gym, do not lift heavy objects, do not run, etc. Walking long distances can also affect the test results.
  5. 2-3 days before the analysis it is better not to visit the bathhouse or sauna.
  6. Avoid emotional overload. Any stressful situations can affect the result.

It is correct to take the test at rest. For this reason, the patient should come to the hospital 30 minutes before the scheduled time. The time it takes to wait will allow your heartbeat and breathing to return to normal. You must remain calm while drawing blood.

If for some reason the patient cannot come to the hospital in the morning, the laboratory test may be rescheduled for the evening. But during the day, a woman should also not eat; she must adhere to all other rules of preparation.

External reasons:

  • With hereditary predisposition.
  • Due to taking hormonal drugs, especially combined estrogen - progesterone oral contraceptives.
  • When switching to a vegetarian diet, in which the body experiences a deficiency of animal proteins.
  • In case of obesity - in this case, excess fat cells become a source of this hormone entering the blood.

The bulk of testosterone in a woman’s body is in the blood in a globulin-bound form. To determine what type of testosterone caused the hormonal imbalance, a study of the free fraction of the hormone in the blood is carried out. To obtain a reliable result, it is recommended to donate blood for hormone levels twice, in the same laboratory. Before taking the tests, you must follow the following recommendations:

  • Tests must be taken on an empty stomach, i.e. The last meal should be no earlier than 12 hours before blood sampling. During this period, it is also prohibited to take any liquid other than water (tea, juice, coffee).
  • The day before the test, stop taking any medications.
  • On the eve of the analysis, smoking, drinking alcohol and sexual intercourse are prohibited.
  • The level of the hormone increases after active physical activity, so exercise is not recommended for two days before the test.

The maximum content of the hormone occurs at the time of ovulation. Since the level of the hormone changes during the menstrual cycle, in order to obtain reliable test results, you need to determine the day when you should take it. The date of the test is calculated based on the duration of the menstrual cycle:

  • With a duration of 21 to 23 days - on the 2-3rd day from the start of menstruation.
  • With a 28-day cycle - on days 4-5.
  • If the cycle lasts more than 28 days - on the 7th day.

To determine on what day you need to undergo the examination, you need to take the first day of the onset of menstruation as the starting point. This will be the first day of the cycle.

If such typical signs are not found, then the reasons for increased testosterone production may be:

  • Eating disorders – eating large amounts of fatty and sweet foods.
  • Uncontrolled use of hormonal drugs, as well as steroids and barbiturates.
  • Ovarian tumors.
  • Increased hormone production in the adrenal glands or dysregulation of its synthesis of central origin (pituitary tumor).

To increase the accuracy of the test result, you need to know what day is best to donate blood. The favorable period depends on the duration of the menstrual cycle. If a woman has an average cycle length of 28 days, then the test should be taken on the 5-6th day of her period. With a short menstrual cycle, the maximum level of the hormone is reached 2-3 days from the day the discharge begins. If the cycle is extended, then the test must be taken on day 7.

Taking certain hormonal medications and various gynecological diseases can shift the cycle, so the day of the test is prescribed by the doctor. This rule is also observed during menopause.

  • fatigue;
  • increased sweating;
  • sleep disturbance (drowsiness or insomnia);
  • increased heart rate;
  • sudden weight gain;
  • pain during sexual intercourse (this condition occurs when there is a lack of discharge);
  • voice change;
  • deterioration of the condition of nails and hair.

A natural decrease in testosterone levels occurs during menopause. At this time, the amount of all hormones decreases, which affects the woman’s condition. If a lack of testosterone is observed in the absence of menopause, it can be caused by:

  • changes in diet (vegetarianism, strict diet);
  • influence of bad habits (smoking, drinking alcohol);
  • changing weather conditions;
  • pathological functioning of the ovaries;
  • obesity;
  • kidney or adrenal diseases;
  • taking medications;
  • genetic predisposition;
  • lack of sun.

How to test for hormone levels

An endocrinologist or therapist can also send a woman for testing. But this is done when there are compelling reasons for diagnosis.

A woman will have to donate blood when the following factors exist:

  • Carrying a baby;
  • Lack of interest in sexual relations;
  • Gynecological diseases;
  • Unstable menstrual cycle;
  • Overweight;
  • Bad feeling;
  • Inability to conceive.

Testosterone levels are closely related to the monthly cycle, so many people are concerned about which day of the cycle to donate blood. With a stable cycle of 28 days, the procedure is prescribed on days 4-5.

A woman will have to prepare for this important test. To do this she will need:

  1. 5-6 days before the analysis, stop using any dosage forms that could affect the result;
  2. For about a week, exclude vigorous physical activity and sports;
  3. 24 hours before the test, intimate relationships, drinking alcohol, and smoking are excluded.
  4. In the preceding days, it is advisable to avoid stressful situations that provoke a surge of hormones.

As for the question of how to take it correctly, first of all, on the day of the test you can’t eat or even drink anything - the test is taken on an empty stomach.

Hormonal testing is not free. You can take it in both public and private institutions, where the likelihood of accuracy is much higher. On average, the price for examination in medical centers and specialized laboratories ranges from 350 to 600 rubles.

Diagnostics

Testosterone in women (the norm of its content in the blood can vary depending on the life stage) is established today simply - you need to donate blood for a detailed analysis from a vein.

Before donating blood for analysis, you need to prepare:

  • stop taking hormonal medications 3-4 days before;
  • in 18 hours Before the analysis, you are not allowed to smoke or drink alcohol;
  • physical activity and sexual intercourse should be limited during the day;
  • on the eve of donating blood after 8 pm and the next morning you cannot eat anything, because the analysis is carried out on an empty stomach;
  • It is better for a woman to conduct such a study on days 6-7 of the menstrual cycle to obtain accurate indicators.

Within a day you will be able to find out the answer. If the result is lower or higher than normal, it will be necessary to undergo an appropriate examination to determine the causes associated with changes in hormonal levels.

In rare cases, the causes of changes in hormone levels may be natural, but this does not exclude congenital and chronic diseases that require professional treatment.

Diagnosis of changes in hormonal balance is carried out in the following areas:

  • an ultrasound scan of the uterus and ovaries is performed;
  • ultrasound of the mammary glands;
  • ultrasound of the adrenal glands and other internal organs;
  • a blood test is taken to determine the concentration of adrenocorticotropic and growth hormone, as well as prolactin and estrogen;
  • conduct a study of general hormonal levels;
  • MRI of the brain (pituitary gland);
  • blood sugar test;
  • blood test for cholesterol.

All types of analyzes and research must be carried out in strict accordance with the requirements. So, a cholesterol test is carried out on an empty stomach, and you cannot eat after 6 o’clock the previous evening. Otherwise, the result will not correspond to real indicators, which will affect the prescribed treatment.

Only after a comprehensive study can conclusions be drawn and measures taken to reduce or increase testosterone levels.

When to take it

A woman's testosterone test results change daily. This feature is considered normal; it depends on the day of the menstrual cycle. In pregnant women, an increase or decrease in hormone levels is associated with gestation.

In most cases, it is recommended to take testosterone on the 5th day of the cycle, provided its total duration is 28 days. If the cycle is shorter, the study is carried out on days 3-4. When it is longer, i.e. more than 28 days - on day 8-9. Depending on the urgency of the situation in which there is a need to conduct a laboratory test to determine the level of the hormone in the blood, the doctor may prescribe a diagnosis for any day.

Knowing the duration of the menstrual cycle, it will be possible to draw a conclusion about the presence of deviations.

If the patient is taking hormones or any other medications, she needs to inform her doctor about this before taking the test. Some drugs can affect the results, so the study may be scheduled for a different date.

Important information: What does a blood test show for antibodies to hCG IgM and IgG

When a patient's menstrual bleeding does not occur regularly, i.e. there is a malfunction, testosterone is released in women 4 days after the start of menstruation.

Food

To increase the production of the hormone in the blood, you need to eat less white bread, rich pastries and a lot of spices. It is worth saturating your food with healthy foods that will help restore hormonal balance.

  • nuts contain vitamins and minerals that are necessary for the synthesis of testosterone;
  • Seafoods are rich in zinc and omega-3, omega-6 acids. It is zinc that is the basis for the hormone, therefore, coupled with the necessary microelements, testosterone production occurs at an accelerated pace;
  • cereals (wheat) are also rich in zinc and other vitamins;
  • legumes, whether fresh, frozen or canned, contain the right combination of protein and fiber to normalize metabolic processes;
  • sweet fruits, which are a storehouse of vitamins and nutrients (bananas, pineapples, melons), should be included more often in the diet.

The level of testosterone in a woman's blood can be balanced by an individual diet. You should exclude fatty and spicy foods, which complicate the digestion process and promote fat deposition.

To reduce testosterone, you need to include:

  • jam, sweet fruits and candied fruits, honey, as they suppress testosterone and promote estrogen production;
  • dried fruits that contain vitamins that lower hormone levels;
  • oats are a unique product that slows down the synthesis of testosterone and promotes its processing into the female sex hormone. However, it is better to cook oatmeal in water, and then add milk, honey or sugar to it.

You should change your diet gradually, giving up familiar foods and replacing them with new ones. Any sudden changes can cause stress for the body and aggravate the general condition.

How to prepare for the procedure?

In order for the analysis of free testosterone for women to be as informative as possible, it is necessary to properly prepare for it. Necessary:

  • take fasting blood samples;

Advice! In the morning before the procedure, you can not only have breakfast, but also drink tea (coffee); you can only drink clean water.

  • on the eve of the procedure, it is necessary to exclude alcohol and nicotine from entering the body;
  • sexual rest is recommended before the procedure;
  • Severe procedures should be avoided before analysis.

Advice! As already mentioned, in order to correctly determine the level of free hormone in the blood, blood samples must be taken on certain days of the cycle. If the cycle is unstable or there are no menstruation, then the day of sampling is determined by the doctor.

The result of the analysis can usually be obtained the next day.

Pharmacy drugs

In women, a number of pharmaceutical drugs help normalize testosterone levels and increase its concentration to the desired level. However, they must be prescribed by a doctor in order to select the required dosage in accordance with the test results. Self-administration of such drugs can significantly increase the level of the hormone and cause an imbalance in the body.

With the necessary degree of attention, the following drugs are used:

  • methyltestosterone;
  • non-local

This is done systemically until the desired effect is achieved, then the medication is stopped.

As the main treatment, a woman is prescribed a drug. Most often these are contraceptives, which help to significantly reduce testosterone levels to 2.34 nmol/l.

These are used as:

  • Goserelin;
  • Regulon;
  • Abarelix;
  • Leuprolide;
  • Spironolactone.

The attending physician should prescribe a specific drug based on the examination results and the woman’s health condition. Such drugs have a strong effect on hormonal levels.

Therefore, they are prescribed only when the permissible level of testosterone in the blood is significantly exceeded in order to eliminate possible consequences. In other cases, testosterone levels are regulated through diet and lifestyle changes.

Reasons for deviations

Testosterone analysis in women - what is it, many patients ask. This study is aimed at determining this hormone in the blood, which allows, if there are deviations, to adjust the balance. Therapy is always determined depending on the clinical case.

So, if an analysis for the hormone testosterone in women showed deviations from the norm, then we can say that some internal organs are not working fully or are not performing their functions at the proper level. Among the most likely causes of a decrease or increase in testosterone in the blood of women, doctors identify the following:

  1. Improper functioning of the adrenal glands;
  2. Presence of gynecological diseases;
  3. Long-term use of hormonal drugs, including contraceptives, without a break to restore the body;
  4. Hereditary predisposition;
  5. Poor nutrition (diet, fasting, overeating).

If there are one or more reasons, you should definitely contact a gynecologist. He will tell you how to take a testosterone test in women, on what day of the cycle and what it means. You should not neglect treatment and visits to these specialists, because if hormonal levels are disrupted, your general health will suffer.

Hormones are involved in the functioning of many body systems. Their deficiency or excess provokes the development of pathologies and deterioration of the general condition. If you have health problems related to the production of hormones, you need to take a blood test. It allows you to identify existing abnormalities and prescribe the correct treatment. Women need to know when and on what day it is better to take the test, since hormone levels may differ at different periods of the cycle.

Folk remedies

There are also folk remedies for increasing hormonal levels:

  • So 100 grams of pollen should be mixed with half a can of condensed milk.
  • The mixture should be kept in the refrigerator for 2 weeks, and then drunk 1 tbsp. in the morning 30 minutes. before meals.
  • You should start taking it with 1 tsp, gradually increasing the dose to the desired level.

It is also recommended to take decoctions of ginseng, rose hips and rowan to increase testosterone levels.

To reduce testosterone levels, folk remedies are also used that have a positive effect on women’s health and hormone production:

  • Red clover contains estrogens of plant origin, which quickly normalize hormonal levels and help reduce the overall level of testosterone in the blood;
  • Angelica can regulate metabolism and normalize the functioning of the ovaries and uterus in women. It also calms the nervous system and relieves stress, helps cope with insomnia, and also increases the sensitivity of all cells to estrogen and progesterone;
  • Peppermint can normalize hormonal balance and restore the functioning of the reproductive system. This herb is soothing and has a pleasant aroma. It can be added to salads, desserts and tea.
  • phytoestrogens contains licorice root, which regulates the functioning of the genital organs and reduces androgen levels.
