目的 探讨冷冻胚胎复活情况及妊娠。方法 对 2 0 0 1年 9月～ 2 0 0 3年 9月在本中心实施体外授精胚胎移植失败 ,再次行冻融胚胎移植 30周期 2 8人进行回顾性分析。结果 30周期 2 8人共冷冻胚胎 15 0个 ,复活 91个 ,复活率 6 0 .7% ,妊娠 8例 ,冷冻胚胎的妊娠率 2 8.6 % ,周期妊娠率 2 6 .7%。结论 冻融胚胎移植能增加一次取卵的总妊娠率 ,降低多胎率。
Objective To investigate the resurrection of frozen embryos and pregnancy. Methods The in vitro fertilization embryo transfer failed from September 2001 to September 2003 in our center, and retrospective analysis was performed on 28 cycles of frozen-thawed embryo transfer in 30 cycles. Results There were 15 0 frozen embryos, 91 resurrected resuscitations and 60.7% rescued in 8 cycles. The pregnancy rate of frozen embryos was 8.66%, and the rate of periodic pregnancy was 26.7%. Conclusion Frozen-thawed embryo transfer can increase the total pregnancy rate of one ovulation and reduce the multiple birth rate.
