Lead author Dr. Darius Paduch, a male sexual medicine specialist at NewYork-Presbyterian Hospital/Weill Cornell Medical Center, and colleagues tracked 12,130 men with mild to severe erectile dysfunction and found 65 percent unable to have an orgasm and 58 percent with ejaculation problems.
"While medications like Viagra or Cialis have been successful in helping many of these men, our research suggests there are other common sexual issues that remain largely unaddressed," Paduch says in a statement. "We must expand the definition of quality of life when it comes to sexual performance. For the last few decades, we have focused on penile rigidity, with erection as a synonym of normal sexual function. However, many patients say that problems with ejaculation -- like decreased force or volume or decreased sensation of orgasm -- are just as critical."
The study, published in the British Journal of Urology International, finds these issues are surprisingly common among men with very mild erectile dysfunction: Orgasm dysfunction was reported by 26 percent in this group, and ejaculation dysfunction by 18 percent.
"This suggests that non-erectile sexual dysfunction is a regular occurrence even in men without erectile dysfunction," Paduch said.
