The Effects of Phosphodiesterase-5 Inhibitors in Men with “Normal” Erectile Function

[摘要] A common belief among the lay population is that oral phosphodiesterase-5 inhibitors will make a “normal” man become “supernormal” regarding his erectile capabilities. Two studies on this topic have been published, both of which have emanated from Italy. In the first study,1 which was reviewed in a previous issue of Reviews in Urology,2 investigators concluded that sildenafil (50 mg) improved erections in normal men. However, the average age of study subjects was 39 years, an age that impotence experts would most likely not equate with “normal” erectile capabilities.
