着床是胚胎定位、黏附,然后侵入子宫内膜的过程。它是一个涉及一系列细胞因子和生长因子,以及胚胎与子宫内膜之间交互对话的复杂过程。胚胎着床是辅助生殖技术中关键的步骤之一,成功植入取决于胚胎的侵入能力和子宫内膜的容受性。胚胎移植前子宫内膜的机械性刺激,包括宫腔镜检查操作、子宫内膜搔刮或者活检,能通过激发炎症反应、调整基因表达,提高子宫内膜容受性,进而提高患者的单胚种植率、临床妊娠率和活产率。 Implantation is the process by which the embryo locates, adheres, and then invades the endometrium. It is a complex process involving a series of cytokines and growth factors, as well as the interactive dialogue between the embryo and the endometrium. Embryo implantation is one of the key steps in assisted reproductive technology. The successful implantation depends on the invasive ability of the embryo and the endometrial receptivity. Mechanical stimulation of the endometrium prior to embryo transfer, including hysteroscopy, endometrial scraping or biopsy, can improve endometrial receptivity by stimulating inflammatory responses, regulating gene expression, and thereby increasing single patient embryo Planting rate, clinical pregnancy rate and live birth rate.
