子宫内膜容受性即子宫内膜处于接受胚胎植入时期所具有的特殊状态,受严格的时间和空间限制,该时期子宫内膜腺体、血管增生,基质水肿蜕膜化,有丝分裂活跃,胞饮突出现,同时各种细胞因子、生长因子分泌量增加,与胚胎发育呈现同步化.胚胎质量和子宫内膜容受性是辅助生殖技术过程中的关键步骤,改善子宫内膜容受性对胚胎的着床、妊娠具有积极意义.内膜清创术(endometrial injury EI)以机械手段直接作用于子宫内膜并改善其容受性,已在临床上取得了较好的临床效果,但是否可广泛应用于临床仍存在争议.本文结合国内外文献对其作用机制、受益人群、操作时间及方法及临床效果进行述评,以期为其临床应用提供参考.“,”Endometrial receptivity that the endometrium in the embryo implantation period has a special state,subject to strict time and space constraints,the period of endometrial glands,vascular proliferation,matrix edema decidualization,mitosis active,Cell metabolism,while a variety of cytokines,growth factor secretion increased,and embryonic development showed synchronization.Embryonic quality and endometrial receptivity are key steps in the process of assisted reproductive technology,improve endometrial receptivity to embryo implantation,pregnancy has a positive significance.Endometrial injury (endometrial injury EI) to mechanical effects directly on the endometrium and improve its tolerance,has been clinically achieved goodi clinical results,but whether it can be widely used in clinical still controversial.This paper reviews the mechanism,benefit population,operation time and method and clinical effect of domestic and foreign literature in order to provide reference for its clinical application.
