AMH and polycystic ovary syndrome: Early studies have suggested that the serum anti-Mullerian hormone (AMH) level and antral follicle count (AFC), as surrogate markers of the ovarian reserve, decline with age in normo-ovulatory women, while this kind of age-related decrease is slower in PCOS patients, and levels are higher in women with PCOS than in normo-ovulatory women of the same age (6, 7).
