Although few studies have been reported the role of D&C in the etiology of thin endometrium but the precise relation between D&C and ultrasonographically thin endometrium remains controversial. Thus the endometrium showed significant thinning after repeated D&C.
Despite the remaining controversy, many studies have shown that ultrasonographic endometrial thickness can be considered as an indicator of endometrial receptivity (the state of endometrial abiliy to accept embryo). Endometrial receptivity is required for successful implantation and pregnancy. Therefore, D&C may affect pregnancy outcome due to decreased receptivity of the thinned endometrium.
