Impact of embryo co-culture with cumulus cells on pregnancy &amp; implantation rate in patients undergoing <i>in vitro</i> fertilization using donor oocyte.

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.
