AMH and polycystic ovary syndrome: To correctly interpret these findings, AMH’s and FSH’s varying potentials in predicting oocyte quantity and quality should be considered: Because of its inhibitory effect on follicle recruitment, AMH levels rise in clinical situations associated with active recruitment, like polycystic ovary syndrome [23], and are low when recruitment is inactive, like in pregnancy [24], with use of oral contraceptives [25] or in women with diminished ovarian reserve [26], [27].
