Impact of embryo co-culture with cumulus cells on pregnancy implantation rate in patients undergoing in vitro fertilization using donor oocyte

摘要

Background & objectives:Cumulus cell co-culture of embryo had been found to be beneficial for achieving better pregnancy and implantation rate (IR). The present study was aimed to evaluate efficiency of cumulus co-culture technique over simple culture of embryo in terms of pregnancy rate (PR) and IR in patients undergoing treatment for infertility using donor oocytes fertilized by intracytoplasmic sperm injection.
