Design: Prospective randomized trial. Setting: Oocyte donation program at the Instituto Valenciano de Infertilidad, Valencia, Spain. Patient(s): Three hundred recipients with normal ovarian function, absence of uterine anomalies, and undergoing their first egg donation were recruited between September 2003 and September 2004. Intervention(s): A computer-based randomization divided the recipients into three groups when hCG was administered to their matched donors. The first group (group A) started P supplementation the day before oocyte retrieval; the second group (group B) started P supplementation on the day of the oocyte retrieval; and the third group (group C) started P supplementation 1 day after the egg retrieval once fertilization was confirmed. Main Outcome Measure(s): Implantation, pregnancy, and ongoing pregnancy rates were the primary outcome measures considered. The secondary outcome measure was the cancellation rate, especially due to fertilization failure. Result(s): Global cancellation rate and cancellation rate due to fertilization failure were significantly higher in group A (12.4% and 8.2% , respectively) than in group C (3.3% and 0% , respectively). Reproductive outcome was similar in all the groups except for a higher biochemical pregnancy rate in group A (12.9% ) than in groups B (6.6% ) and C (2.3% ). Conclusion(s): Initiation of P on day + 1 of embryo development decreases cancellation rates of day 3 embryo transfers in extensive programs of ovum donation without any deleterious effect on pregnancy outcome or implantation rate. | Escribá M.J Bellver J Bosch E. 张旸 | 2006 | 世界核心医学期刊文摘(妇产科学分册)2006，0，11： | 2 |
