Higher circulating levels of AMH in older women with PCOS, coupled with a higher number of retrieved oocytes (during IVF), suggest differences in the follicular content of their ovaries, and prior research has shown that it is not due to the increase in primordial follicle recruitment nor changes in atresia, rather it is due to the slow primary follicle growth and stockpiling of classic primary follicles occurring in the setting of PCOS (Maciel et al., 2004). Here, AMH is linked to polycystic ovary syndrome.
