Efficiency of metaphase II oocytes following minimal/mild ovarian stimulation in vitro fertilization

Efficiency of metaphase II oocytes following minimal/mild ovarian stimulation in vitro fertilization

BACKGROUND An inverse relationship between oocyte efficiency and ovarian response was reported in conventional IVF. The purpose of this study was to report metaphase II (MII) oocyte efficiency according to oocyte yield in minimal/mild stimulation IVF (mIVF) and to assess whether oocyte yield affects live birth rate (LBR). METHODS Infertile women (n = 264) aged < 39 years old with normal ovari...

P-103: Polscope Analysis of Meiotic Spindle and Zona Pellucida Birefringence of Metaphase II Oocytes in Polycystic Ovarian Syndrome Patients

Background Polycystic ovarian syndrome (PCOs) is one of the most common causes of infertility in women of reproductive age. Currently, one of the best therapeutic options for PCOs patients is ICSI. Moreover, IVM can be a useful technique for women with PCOs who are at the risk of ovarian hyperstimulation syndrome (OHSS). On the other hand, the oocyte quality can be a determining factor for outc...
