控制性超促排卵对子宫内膜接受性的不利影响可能是导致体外受精-胚胎移植(IVF-ET)低妊娠率、高流产率的原因之一,其作用机制需要更深入的研究。阐述控制性超促排卵对子宫内膜接受性的影响因素,并提出几点可能改善控制性超促排卵后子宫内膜接受性,提高胚胎植入率、妊娠率的措施。
The adverse effect of controlled ovarian hyperstimulation on endometrial receptivity may be one of the causes of low pregnancy rate and high abortion rate of IVF-ET. The mechanism of action needs further study. The factors influencing endometrial receptivity of controlled ovarian hyperstimulation were expounded and some measures that might improve endometrial receptivity and increase embryo implantation rate and pregnancy rate after controlled ovarian hyperstimulation were proposed.
