Anti-Müllerian hormone is produced by the preantral and antral follicles of the ovaries throughout a woman's reproductive life.
Specifically, responsible for synthesizing it are the granulosa cells that surround the egg. The measurement of AMH in blood indicates approximately the quantity or number of eggs a woman has, i.e. her ovarian reserve. To complete the information on the ovarian reserve it is necessary to perform a transvaginal ultrasound with an antral follicle count.
It is important to remember that both the AMH and the antral follicle count are quantitative markers and do not provide us with information about egg quality. The parameter that best correlates with the quality of the oocytes is the woman's age.
