Abstract
Abstract Background Women with polycystic ovarian syndrome (PCOS) may undergo laparoscopic ovarian drilling (LOD). To find out whether endometrial scratch, at time of LOD, could improve live birth rate in subfertile women with PCOS, a randomized controlled trial was conducted. Results There was no evidence of a significant difference in cumulative live birth rate between women who had endometrial scratch at time of LOD and those who had LOD only (38.1% and 34.3% respectively, odds ratio 1.18, 95% CI (0.67, 2.07); p = 0.57). Conclusion Women undergoing laparoscopic ovarian drilling should not be subjected to endometrial scratch as it does not lead to improvement in live birth rate. The study was prospectively registered on 25 April 2014 in ClinicalTrials.gov with identifier number NCT02140398.
