Local endometrial injury and IVF outcome: a systematic review and meta-analysis.

A systematic review was conducted of the influence of local endometrial injury (LEI) on the outcome of the subsequent IVF cycle. MEDLINE, EMBASE, the Cochrane Library, National Research Register, ISI Conference Proceedings, ISRCTN Register and Meta-register were searched for randomized controlled trials to October 2011. The review included all trials comparing the outcome of IVF treatment in patients who had LEI in the cycle preceding their IVF treatment with controls in which endometrial injury was not performed.
