High proportion of immature oocytes in a cohort reduces fertilization, embryo development, pregnancy and live birth rates following ICSI

18 Jun 2019

Abstract excerpt

RESEARCH QUESTION: Ooplasmic maturity has been studied for some time, but remains poorly defined. This study aimed to evaluate metaphase II (MII) oocyte competence in terms of fertilization, embryo development and cycle outcomes, according to the oocyte maturity ratio. DESIGN: Couples treated by intracytoplasmic sperm injection (ICSI) between 1993 and 2017 with female partners ≤35 years old were included. Cycles...
