Research progress on the improvement of thin endometrial receptivity by endometrial scratching
Thin endometrium is the main cause of defective endometrial receptivity(ER),which can lead to infertility or miscarriage.The most common cause of female infertility or miscarriage is the disturbance of the embryo implantation process,which is determined by various factors,including factors from the embryo itself and maternal factors.The development of assisted reproductive technology has improved the rate of obtaining high-quality embryos.Therefore,improving ER is currently the main problem in treating infertility.Endometrial scratching(ES)can improve ER,and it can effectively treat infertility patients with thin endometrium.The current article reviews the research progress on the improvement of thin endometrial receptivity by ES.
