Design: Prospective randomized clinical trial. Setting: Private assisted reproductive technology center. Patient(s): Two hundred eighty-one women demonstrating poor ovarian response to controlled ovarian hyperstimulation. Intervention(s): Women who were poor responders were randomly allocated to day 2 or day 3 embryo transfer following oocyte retrieval. Main Outcome Measure(s): Implantation rates and pregnancy rates per oocyte retrieval and embryo transfer. Result(s): The clinical pregnancy rates per oocyte retrieval (37.2% vs. 21.4% , respectively; P < .05) and per embryo transfer (38.9% vs. 24.1% , respectively; P < .05) were significantly higher in the day 2 embryo transfer group compared with day 3. On the other hand, implantation rates were not different between groups (23.9% vs. 17.2% , respectively; P = .08). Conclusion(s): Our results demonstrated that trans-fering embryos on day 2 could provide an alternative to the management of poor responder patients.展开更多

The impact of coasting in a cycle in which GnRH antagonist is used was evaluated in 29 women, and it was found that coasting did not deleteriously affect the outcome in high-responder patients undergoing COH with GnRH antagonists.展开更多
