AMH hormone is a Müllerian inhibitory substance responsible for embryonic sex differentiation and is involved in spermatogenesis and follicle maturation. By its quantity, the work of the human gonads is judged. In medicine, a hormone test is often used to diagnose female infertility.
Being in the body of men and women, the AMH hormone performs completely different functions. Few people know that a fetus in the womb up to 17 weeks has signs of both sexes. Under the action of this particular hormone, he undergoes a reverse transformation of the Müllerian duct, which is the rudiment of the female reproductive system. This is how the sex of the baby is determined.
In the female body, Muller's substance is responsible for the functioning of the reproductive organs. It controls the sequence of maturation of follicles in the ovary. The essence of its action is to prevent the eggs from ripening all at the same time. Simply put, the duration of the female reproductive age and conception depends only on it. But in the male body, the AMG hormone is responsible for timely and proper puberty. Generally, low hormone levels lead to earlier maturation, while high hormone levels lead to a delay.
What are the indicators of AMH? Its norm in the blood for men is 0.49-5.98 ng / ml, and for women - within 1.0-2.5 ng / ml. You should know that throughout the entire female reproductive period, the hormone index does not change, a decrease occurs only with the onset of menopause or with obesity. A significant deviation from the norm upwards may indicate polycystic ovaries, delayed sexual development, tumors in the tissues of the ovary.
What will AMG tell about? An analysis of the content of this substance in the blood is prescribed to diagnose sexual development in boys, to determine the prognosis for the onset of menopause in women. Also indications for the appointment of the analysis are:
- diagnosis of male and female infertility;
- assessment of a woman's ovarian reserve;
- diagnosis of cryptorchidism or anorchism;
- assessment of male gonadal function;
- postoperative care for ovarian cancer;
- monitoring for chemotherapy for
- problems with IVF fertilization;
- birth of a child with signs of both sexes (to determine the dominant sex).

The indicator of the mentioned hormone in the blood gives an accurate description of the work of the ovaries. The analysis helps the doctor to make an accurate diagnosis and prescribe a comprehensive treatment.
For analysis, venous blood taken on the 3rd-5th day of the menstrual cycle is used, which is examined using the ELISA method. No special preparation is required before donating blood. The conditions are onlyare: the last meal for 12 hours and the exclusion of hormonal drugs 2 days before the study.
What to do if the content of AMH-hormone is reduced? The answer is simple: nothing. Doctors believe that even with an artificial increase in the hormone, the number of follicles in the ovaries will remain unchanged. However, do not despair. Modern medicine is ready to offer other methods of infertility treatment, including IVF. All you have to do is not waste your precious time.
