AMH and polycystic ovary syndrome: In 2011, Nicolas Crisosto et al. found that AMH serum level in the female neonates born from mothers with PCOS, who had not been treated with metformin during pregnancy, was higher compared to the control group; however, its level in the female neonates born from mothers having PCOS, who had been treated with metformin during pregnancy, was similar to that in the control group [17].
