Office hysteroscopy (OH) is the gold standard for evaluation of the endometrial cavity. Although the endoscopic approach has been proven to increase pregnancy rate in women who experienced prior implantation failure, evidence on treatment of unsuspected hysteroscopically-diagnosed endometrial lesions, to improve IVF outcome, is still lacking. Nevertheless,clinicians tend to use OH routinely prior to IVF because the psychological and financial burden that infertile couples may experience as a consequence of failed IVF cycle is unjustifiable.Yet, costs and invasiveness of OH counteract its global implementation to all women prior to IVF.
