Evaluation of the effect of endometriosis on oocyte quality and endometrial environment by comparison of donor and recipient outcomes following embryo transfer in a shared oocyte program
Purpose: To determine whether endometriosis has an effect on the uterine environment vs the oocyte itself. Methods: A retrospective study comparing pregnancy outcome of infertile donors sharing oocytes with donor egg recipients according to whether the donor or recipient had endometriosis or not was carried out. Results: There were 26 transfers from donors with endometriosis vs 144 in donors without endometriosis. The clinical and viable PRs and implantation rates were 42.9%, 38.1 %, and 29.4% for the endometriosis group vs 60.9%, 51.9%, and 33.2%, respectively, for donors without endometriosis (p = NS). The clinical and viable PRs and implantation rates for donors with endometriosis per ET was 41.2%, 35.3%, and 20.4% vs 50.4%, 48.0% and 28.4% for donors without endometriosis, respectively (p = NS). Conclusions: Though no significant differences were found in donors with or without endometriosis in any parameters, there did appear to be a trend for lower PRs and implantation rates in women undergoing controlled ovarian hyperstimulation.
