摘要
目的:确定囊胚期胚胎的最佳种植时期,提高胚胎移植率。方法:２０只产过一窝的ＫＭ母鼠分为两组作为胚胎移植的假母,比较了２．５ｄ假母和３．５ｄ假母子宫移植的成功率。结果:２．５ｄ的假母囊胚子子宫移值后的妊娠率为１０%,３．５ｄ的假母囊胚子宫移植后的妊娠率为６０%。结论:假母子宫内膜发育的同步性与囊胚移植后是否种植并生产有着重要的关系。
ve: To determine the optimal time for blastosphere implantation in order to improve the survival rate of embryonic implantation. Methods: 20 female KM mice that had experienced one birth were divided into two groups and used as pseudo-pregnant mice for embryonic implantation. The successful rates of implantation after 2. 5 days and 3.5 days were compared. Result: The pregnant rate after 2.5 days of the implantation was 10% , compared to 60% after 3.5 days. Conclusion: The synchronous development of the endometria in pseudo-pregnant mice plays an important role in the successful blastosphere implantation in mice.
