AMH causes regression of Müllerian ducts during male fetal development. Recently, AMH was detected in the adult ovary, principally in granulosa cells (GCs). Studies have demonstrated a 1.5–5 fold increase in serum AMH in women with PCOS compared to normal ovulatory women. The AMH rise was assumed to be secondary to increased numbers of follicles. Interestingly, the insulin sensitiser metformin, which is in widespread use in PCOS, caused a significant reduction in ser...

AMH, the fetal testicular sexual differentiative factor, is now implicated in adult ovarian function. Antral follicle immunohistochemistry demonstrated AMH protein and message, the staining peaking around 4 mm. Interestingly, AMH-knockout mice have increased FSH sensitivity. Our aim was to measure AMH in follicular fluid and cell-conditioned medium and AMHRII in normal ovaries from women undergoing TAH/BSO.Follicles were dissected intact, follicular flui...
