Reproductive potential of MII oocytes following minimal or conventional ovarian stimulation: analysis of 564 treatment cycles from a randomized clinical trial

Abstract

In previous retrospective studies (Patrizio 2009, Stoop 2012) overall oocyte utilization following conventional ovarian stimulation was found to be constantly low (<5%) and declining even further (<1%) in >37 years old women. It was suggested that mild ovarian stimulation could yield eggs of better quality (Inge, 2005). However to date there are no large-scale analyses available from well-controlled trials on the reproductive potential of MII oocytes obtained via mild IVF in comparison to conventional stimulation.
