Erectile dysfunction in prostate cancer patients treated with intensity-modulated radiation therapy.

Background: Sexual dysfunction is an important side-effect after radiotherapy (RT) for prostate cancer (PCa). The aim of this study was to compare sexual functions of PCa patients before and after intensity-modulated RT and to analyze their correlation with penile bulb (PB) doses and patient characteristics.

Materials And Methods: Forty-two patients who underwent RT ± hormone therapy for PCa between 2010 and 2013 were analyzed.
