Circulating AMH is mainly produced by preantral and small antral follicles in the ovaries.[7] AMH could be served as an excellent predictor for the menopausal transition than other ovarian reserve markers, and the reduction of AMH is the earliest event identified in women who later developed ovarian insufficiency.[8] Therefore, AMH shows a good predictive value for women at risk of POI. Here, AMH is linked to ovarian dysfunction.
