Abstract

Purpose of review

To review updated information on the influence of endometrial scratching on IVF.

Recent findings

Endometrial receptivity remains an important rate-limiting step affecting the success of IVF. The current evidence on the effect of endometrial scratching on IVF ranges from marked improvement, no difference to a potentially negative impact. The heterogeneity of studies presents a challenge in interpretation of data for routine clinical practice.

Summary

Endometrial scratching performed in the preceding cycle is associated with improved clinical pregnancy and live birth rates in women with recurrent implantation failure, but not in unselected subfertile women undergoing IVF. Most of the current literature are underpowered and at high risk of bias.
