摘要 体外受精与胚胎移植(IVF—ET)技术经历了三十年,而妊娠率还是徘徊在30%~40%之间,这很大程度上是由于胚胎植入率低,还有部分在种植后生化妊娠夭折,约20%为临床流产。目前的研究主要关注于配子、胚胎的早期发育异常,特别是植入前的非整倍体的研究和流产胚胎的染色体分析,而在内膜的接受性研究发展相对缓慢,很大程度上限于没有一个很好的人类胚胎植人模型。然而,临床上提出了诸多对胚胎植人问题的疑惑。 Comparing to the research on potential development of oocyte and embryo,endometrium receptivity is less and slowly understood, because there is no good implantation research model in human. The paper discusses the following questions in clinical embryo implantation, the clinical accident ectopic pregnancy,the importance of decidualization, the proper location of embryo invasion, and the effect of curettage of endometrium on implantation.
