冻融周期移植2个胚胎是合理的选择。
结果49例进行53个周期的冻融胚胎移植，获临床妊娠11例，临床妊娠率为20.8%。
Results Among the 49 cases who had received cryopreservation thawed embryo transplantation for 53 cycles, 11 cases achieved clinical pregnancy (with the rate of 20.8%).
与同期新鲜胚胎移植周期的种植率27.62%比较，冻融胚胎移植的种植率13.28%显著降低（P<0.01）。
The implantation rates of frozen-thawed embryo transfer cycle was significantly lower than fresh embryo transfer cycle(13.28% Vs. 27.62% respectively P<0.01).
