Purpose: To determine if the sharing of oocytes by an infertile woman with an egg recipient for financial advantages has any negative impact on the success rate for the donor. Methods: A matched controlled study was performed comparing pregnancy outcome of women undergoing in vitro fertilization-embryo transfer (IVF-ET) but sharing half of their eggs with a recipient vs women undergoing IVF-ET but not sharing oocytes. Results: Even though more women sharing oocytes deferred fresh transfer and cryopreserved the embryos because of a greater likelihood of ovarian hyperstimulation syndrome, there was no difference in pregnancy rates between the two groups after their first embryo transfer whether it was with fresh or frozen-thawed embryos. Conclusions: Sharing of oocytes by a woman undergoing IVF-ET does not jeopardize her chance of a successful outcome following embryo transfer.
