子宫内膜容受性主要是指子宫内膜处于一种允许胚泡黏附直至完成胚胎着床的状态,其时间是受到严格限制的,子宫内膜“种植窗”仅为排卵后的第6~8天,持续时间不超过2d[1],这期间,子宫内膜的血供是否丰富对子宫内膜的容受性有着重要的影响。研究证实,在体外受精—胚胎移植(In vitro Fertilization And Embryo Transfer,IVF-ET)过程中,胚胎能否成功在宫腔内种植并生长发育与患者子宫内膜内
Endometrial receptivity mainly refers to the endometrium in a state that allows blastocyst adhesion until completion of embryo implantation, and its duration is severely restricted. Endometrium “implantation window” is only the first 6 to 8 days, the duration of not more than 2d [1], during this period, the endometrial blood supply is rich in endometrial tolerance has a significant impact. The study confirmed that in vitro fertilization and embryo transfer (IVF-ET) process, the embryo can be successfully grown in the uterine cavity and the growth and development of patients with endometrial
