The aim of this study was to compare the reproductive outcomes between infertile women who underwent hysteroscopic uterine septum resection and those who required a second look hysteroscopy due to residual septum prior to intracytoplasmic sperm injection (ICSI) cycles with selective single 'Grade A' embryo transfer (ET). All second look hysteroscopies were performed due to partial remnant septum in a control three dimensional transvaginal ultrasonography (3D TVUSG) after the first hysteroscopic resection. Miscarriage and biochemical pregnancy rates were not different between the groups while clinical pregnancy and live birth rates were significantly higher in Group 2 than in Group 1. Second look hysteroscopic metroplasty performed to restore remnant septum significantly improves live birth rate as well as clinical pregnancy rates while it appears not to alleviate abortion and biochemical pregnancy rates in women undergoing ICSI-ET.IMPACT STATEMENT What is already known on this subject? The effect of hysteroscopic septum resection on reproductive outcomes in IVF treatment in infertile patients with uterine septum is not clearly known. What do the results of this study add? With the selective single ET strategy, complete or partial hysteroscopic correction of the uterine septum before ICSI and subsequent resection of the residual septum with control hysteroscopy significantly increases the live birth rates in the infertile population. What are the implications of these findings for clinical practice and/or further research? In the group of infertile patients with uterine septum, second control hysteroscopy should be performed 1 month later for residual septum or adhesions after hysteroscopic septum resection performed once.
