Anti-Mullerian Hormone (AMH), Female - AMH-MIS may be used in the investigation of ovarian reserve since AMH concentrations in adult women reflect the number of small antral and preantral follicles entering the growth phase of their life cycle. These follicles are proportional to the number of primordial follicles that still remain in the ovary, or the ovarian reserve. AMH decreases throughout a woman's reproductive life, which reflects the continuous decline of the oocyte/follicle pool with age and, accordingly, ovarian aging.
