Effects of chronic vardenafil treatment persist after end of treatment in rats with acute arteriogenic erectile dysfunction.

Introduction: In our previous study, chronic vardenafil treatment improved erectile function soon after the end of the treatment in rats with acute arteriogenic erectile dysfunction (ED).

Aim: The aim of this study is to evaluate whether the effects of chronic vardenafil treatment persist after the end of treatment using rats with acute arteriogenic ED.

Methods: Rats were randomly divided into three groups: (i) control; (ii) ligation; and (iii) vardenafil + no treatment.
