ObjectiveTo compare final embryo disposition between patients and donor oocyte recipients.DesignRetrospective study.SettingPrivate infertility practice.Patient(S)Patients undergoing IVF with embryo cryopreservation.Intervention(S)None.Main Outcome Measure(S)Final cryopreserved embryo disposition.Result(S)A total of 1,262 patients using autologous oocytes had 5,417 embryos cryopreserved. A majority either used their embryos (39%) or continued storage (35%). Of 364 patients, who did not use their remaining 1,406 embryos, 77 (21%) donated 290 embryos to other infertile couples, 41 (11%) donated 160 embryos for research, and 246 (68%) discarded 956 embryos. Concurrently, 272 donor oocyte recipients had 1,233 embryos cryopreserved. A majority either used their embryos (40%) or continued storage (23%). Of 110 recipients that did not use their remaining 455 embryos, 62 (56%) donated 280 embryos to other infertile couples, 6 (6%) donated 31 embryos for research, and 42 (38%) discarded 144 embryos.Conclusion(S)In our patient population, a higher proportion of patients with infertility ultimately used or stored their cryopreserved embryos for future reproduction compared with donor oocyte recipients. However, recipients were much more likely to donate to other infertile couples and less likely to discard their remaining embryos compared with patients.Copyright © 2011 American Society for Reproductive Medicine.
