Anti-Mullerian hormone (AMH) is a glycoprotein secreted by granules of immature supportive cells and ovarian sinus follicles and small follicular follicles. AMH is secreted by ovarian intramedullary follicles and small follicles, and its level is directly related to the number of ovarian follicles.

It is difficult to detect AMH in the serum of the newly born baby girl. After a few weeks of birth, the AMH began to increase and reached its peak in the late adolescence. This was consistent with the increase in the number of follicles from birth to adolescence and the increase in the number of preantral follicles. Adult women with age, follicular reserve gradually decreased, AMH decreased, until after menopause AMH can not be detected.

Compared with follicle stimulating hormone and luteinizing hormone, AMH fluctuation is small, and AMH is directly related to the number and age of sinus follicles. Therefore, in recent years, AMH has been used to evaluate ovarian function.

Advantages of AMH detection

1. AMH does not change with the menstrual cycle, can be checked at any time blood.

2. AMH is not affected by hormonal contraceptives.

3. AMH can reflect ovarian reserve function more accurately and earlier.
