Reproductive potential of mature MII oocytes following natural cycle IVF / minimal ovarian stimulation: analysis of 2876 treatment cycles from a single Japanese center

Abstract

In previous studies oocyte utilization following conventional ovarian stimulation was found to be constantly low (<5%) and has declined even further (<1%) in >37 years-old women. Although it was suggested that mild ovarian stimulation could yield better quality eggs to date there are no large-scale analyses on the reproductive potential of MII oocytes following mild IVF.
