Endometrial injury in women undergoing assisted reproductive techniques.

Implantation of an embryo within the endometrial cavity is a key step in assisted reproductive techniques (ART). It has been suggested that intentional endometrial injury, such as endometrial biopsy or curettage, prior to embryo transfer improves the chances of implantation and further development thereby increasing the likelihood of live birth. The effectiveness and safety of this procedure is, however, still unclear.
