title: Hysteroscopic findings in women with recurrent IVF failures and the effect of correction of hysteroscopic findings on subsequent pregnancy rates.
abstract: BACKGROUND
  Our aim is to evaluate the incidence of unrecognized uterine abnormalities in cases with recurrent IVF failure by screening office hysteroscopy (OH), and impacts of treatment of hysteroscopic findings on the success rate of IVF.
  
  
  METHODS
  The retrospective and descriptive study was conducted at assisted reproduction unit in a tertiary medical center. One hundred and fifty-seven patients with a history of recurrent IVF failures underwent hysteroscopy between May 2009 and March 2012. Hysteroscopy (diagnostic or operative, as appropriate) was performed to evaluate the endometrial cavity in patients with two or more IVF failures and Incidence of abnormal hysteroscopic findings and the clinical pregnancy rate (CPR) in subsequent IVF cycles were assessed.
  
  
  RESULTS
  In all, 44.9 % of the patients included in this study had abnormal hysteroscopic findings and 75 women (48.1 %) became pregnant following hysteroscopy. Of these pregnancies, 36 occurred in women with corrected endometrial pathology, the majority of which was identified as endometrial polyps. Implantation rate and clinical pregnancy rate were statistically significant increased after polipectomy.
  
  
  CONCLUSIONS
  Abnormal findings on hysteroscopy are significantly higher in patients with previous ART failure and hysteroscopy could be seen as a positive prognostic factor for achieving pregnancy in subsequent IVF procedure in women with a history of RIF.
