冻融胚胎移植(frozen-thawed embryo transfer,FET)因其增加累计妊娠率,降低了体外受精周期的多胎妊娠风险及减少了中、重度卵巢过度刺激综合征(OHSS)的发生,比重复再次取卵周期耗时短等诸多优点而引起各生殖中心的重视。内膜准备方案是保证胚胎成功着床的关键,现有的内膜准备方式有自然周期、促排卵周期、激素替代周期等,探讨总结适合不同类型患者的最佳内膜准备方式对冻融胚胎有重要意义。 Frozen-thawed embryo transfer (FET) reduces the risk of multiple pregnancy in vitro fertilization cycles and reduces the incidence of moderate and severe ovarian hyperstimulation syndrome (OHSS) due to its increased cumulative pregnancy rate, Egg cycle time-consuming and many other shortcomings caused by the reproductive center attention. Endometrial preparation program is to ensure the successful implantation of the key embryos, the existing endometrial preparation methods are natural cycle, ovulation cycle, hormone replacement cycle, to explore the best for different types of patients with the preparation of the endometrial preparation of frozen-thawed embryos There’s important meaning.
