近年来,随着玻璃化冷冻技术的推进,使得冷冻胚胎的复苏率有了明显提高,甚至已有报道冻融胚胎移植(FET)周期的妊娠率高于新鲜胚胎移植。由此,有些学者提出实施全部胚胎冷冻策略,取消新鲜胚胎移植周期,择期复苏冷冻胚胎再移植,以期获得更好的疗效和安全性。在2016年欧洲人类生殖与胚胎学会(ESHRE)年会上,多名专家围绕全部胚胎冷冻时代是否来临这一争议性话题阐述了自
In recent years, with the advancement of vitrification technology, the recovery rate of frozen embryos has been significantly improved, and even the pregnancy rate of frozen-thawed embryo transfer (FET) cycles has been reported to be higher than that of fresh embryo transfer. Therefore, some scholars proposed to implement all the embryo freezing strategies, abolish the cycle of fresh embryo transfer, elective resuscitation of frozen embryos and replantation in order to obtain better efficacy and safety. At the 2016 Annual Meeting of the European Society for Human Reproduction and Embryology (ESHRE), several experts elaborated on the controversial topic of whether the entire embryonic freezing era has come
