Human oocyte and preembryo donation: An evolving method for the treatment of infertility

Abstract

The utilization of oocyte and preembryo donation in the treatment of infertility has recently expanded. Since 1983, modifications in the retrieval of donated female gametes have enhanced both the safety and the efficacy of the procedure. Pregnancy rates in women receiving donated preembryos are remarkably high, with success occurring in 25% to 50% of transfer cycles. The technology used for preembryo donation continues to evolve, and the current and future role of ovum donation in the treatment of infertility is expanding. © 1990.
