The facts that compared to ovulatory women with PCOS, anovulatory women with PCOS present AMH concentrations 18 times higher [59], with AMH levels correlated to the severity of the condition in terms of anovulation, and the fact that the AMH/AMHR2 system is dysregulated by LH only in GCs from anovulatory women with PCOS (reviewed in [24]), indicate that these increased AMH effects are related to menstrual disorders in patients with PCOS. The gene discussed is AMHR2; the disease is polycystic ovary syndrome.
