摘要
Objective: To determine accumulated conception and live birth rates in ovum donation. Design: Retrospective study from a computer database. Pregnancies with one gestational sac observed by ultrasound have been included as conceptional cycles and pregnancies that resulted in one live child were recorded for the analysis of the live birth rates. Life table analysis was applied. Setting: Oocyte donation program at the Institute Valenciano de Infertilidad. Patient(s): Three hundred ninety-seven recipients undergoing a total of 627 ETs were analyzed. Intervention(s): Ovarian stimulation and ovum pick-up in donors. Uterine ET in recipients after appropriate exogenous steroid replacement. Main Outcome Measurement(s): Accumulated and estimated (95% confidence intervals [CI]) conception and live birth rates in the oocyte donation program as well as considering age and cause of infertility of the recipients. Result(s): Pregnancy rate after one cycle was 53.4% (CI 50.9% to 55.9%), with a delivery rate of 42.6% (CI 40.1% to 45.1%). Accumulated pregnancy rate increased up to 94.8% (CI 90.6% to 99.0%) after four transfers. Similarly, live birth rates reached 88.7% (CI 88.1% to 89.3%) after four attempts of ET by ovum donation. Cycle fecundity rates were maintained at approximately 50% after each attempt. Implantation rate was 18.3% (430/2,340 replaced embryos). Age and cause of entering the program did not influence the overall results of ovum donation. Conclusion(s): Oocyte donation is a successful treatment modality for infertile couples that offers even higher success rates than natural conception. No difference in cumulative pregnancy rate was observed regardless of recipient age, indication for oocyte donation, or number of cycles attempted.
