AMH and polycystic ovary syndrome: Taieb et al. [26] showed that both FSH and cAMP up-regulated AMH mRNA expression in human luteinized GCs, whereas Pellatt et al. [27] did not detect any effect of FSH on AMH production by GCs derived from normal ovaries, but in GCs from women with polycystic ovaries FSH stimulation decreased significantly AMH levels.
