AMH (Anti Mullerian Hormone)

AMH is a product of granulosa cells(in the ovary) of the preantral and small antral follicles in women. Production of AMH regulates folliculogenesis by inhibiting recruitment of follicles from the resting pool in order to select for the dominant follicle, after which the production of AMH diminishes. AMH can also serve as a molecular biomarker for relative size of the ovarian reserve. In humans, this is helpful because the number of cells in the follicular reserve can be used to predict timing of menopause. AMH can also be used as a marker for ovarian dysfunction, such as in women with polycystic ovary syndrome (PCOS).

AMH expression is greatest in the recruitment stage of folliculogenesis, in the preantral and small antral follicles. This expression diminishes as follicles develop and enter selection stage, upon which FSH expression increases
