Abstract

ObjectiveThe aim was to determine the number and the grade of oocyte-corona-cumulus complex (OCCC) and the most viable embryos for transfer in women with endometriosis compared to those with tubal factor infertility.Study methodsPatients underwent in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) at the Yale IVF program. The endometriosis group of 135 patients was monitored in 262 consecutive cycles. The controls consisted of 103 patients with tubal factor infertility undergoing 203 consecutive assisted reproductive technology (ART) cycles. All the patients underwent laparoscopy before IVF treatment. Response to gonadotropins, the oocyte and embryo grade, fertilization, cleavage, implantation, pregnancy, delivery and abortion rates were noted.ResultsOocyte-corona-cumulus complex (OCCC), two-pronuclear (2PN) oocytes, and the grade 1 and 2 embryos on days 2 and 3 were lower in women with endometriosis compared to those with tubal factor infertility. Higher total gonadotropin requiremen...
