%X Background: The aim of this study was to compare the effects of easy and difficult embryotransfers (ET) on implantation and pregnancy rates.Materials and Methods: In this prospective study, we analyzed the results of 706 ET proceduresover a 12-month period. An easy ET was defined as a transfer that occurred without the useof force or other instrumentation. A difficult ET was defined as the use of force for catheterplacement, and/or the use of additional instruments, and/or manipulation. Pregnancy rate wascompared between patients with easy or difficult ETs.Results: There was a significantly higher implantation rate in the easy group (21.7%) comparedto the difficult group (12.1%, p<0.05).The easy group had a higher pregnancy rate (38.1%)compared to patients who had difficult ETs (21.4%; p<0.05).Conclusion: Any uterine manipulation during ET adversely affects in vitro fertilization (IVF).Precaution should be taken to identify possibly difficult ET cases in advance.
