AMH hormone is a Mueller inhibitory substance responsible for differentiating the sex of the embryo and participating in spermatogenesis and follicular maturation. By its quantity, the work of the human sex glands is judged. In medicine, a hormone test is often used to diagnose female infertility.
Being in the body of men and women, AMH hormone performs very different functions. Few people know that a fetus that is in the womb before 17 weeks has signs of both sexes. Under the influence of this particular hormone, he undergoes the reverse transformation of the Mueller duct, which is the germ of the female reproductive system. And so the sex of the child is determined.
In the female body, Mueller's substance is responsible for the work 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 to all at the same time. Simply put, the duration of female reproductive age and conception depends only on it. But in the male body, AMG hormone is responsible for timely and correct puberty. As a rule, a low level of the hormone leads to earlier maturation, and a high one leads to a delay.
What are the AMG indicators? Its norm in the blood for men is 0.49-5.98 ng / ml, and in women - in the range of 1.0-2.5 ng / ml. You should be aware that throughout the entire female
reproductive period, the hormone indicator does not change, a decrease occurs only with the onset of menopause or with obesity. A significant deviation from the norm to a large extent may indicate polycystic ovaries,
delayed sexual development, and tumors in the tissues of the ovary.
What will the AMG talk about? An analysis of the content of this substance in the blood is prescribed for the diagnosis of sexual development in boys, determining the prognosis of the onset of menopause in women. Also indications for the purpose of analysis are:
- diagnosis of male and female infertility;
- assessment of the ovarian reserve of a woman's body;
- diagnosis of cryptorchidism or anorchism;
- assessment of the function of male gonads;
- postoperative monitoring for ovarian cancer;
- chemotherapy follow-upovarian cancer;
- fertilization problems with IVF;
- the birth of a child with signs of both sexes (to determine the dominant gender).
The indicator of the mentioned hormone in the blood gives an accurate description of the work of the ovaries. The analysis helps the doctor make an accurate diagnosis and prescribe a comprehensive treatment.
For analysis, venous blood taken for 3-5 days of the menstrual cycle is used, which is examined using the ELISA method. Special preparation before blood donation is not required. The conditions are: the last meal in 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 ways to treat infertility, including IVF. You should just not miss the priceless time.
