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. The gene discussed is BRD2; the disease is polycystic ovary syndrome.
