OBJECTIVE: To describe a pregnancy after human donor oocyte cryopreservation in association with intracytoplasmic sperm injection in a patient with ovarian failure. SETTING: Department of Reproductive Medicine, CER Medical Institute, Buenos Aires, Argentina. PATIENT: A 48-year-old patient with ovarian failure. RESULTS: Ten donated oocytes were cryopreserved. Survival after thawing was 30%. Three oocytes were microinjected, and two embryos were obtained. The fertilization rate was 66%, and embryo development was 100%. Both embryos were transferred to a patient who had received hormonal replacement therapy. The attempt was successful, and a pregnancy was achieved after the transfer. CONCLUSION: In association with intracytoplasmic sperm injection, an adequate technique of freezing and thawing of human oocytes might achieve encouraging results in ART programs.
