Researchers found that regular users of drugs like aspirin, acetaminophen, ibuprofen, and Celebrex were 38 percent more likely to have erectile dysfunction than men who didn't take the so-called nonsteroidal anti-inflammatory painkillers.
Such drugs are thought to block the hormones that govern men's erections.
After accounting for factors like age, weight, high blood pressure and heart disease, the researchers still found a 38-percent higher risk of erectile dysfunction among men on painkillers.
Still, because the study didn't test painkillers directly, Inman cautioned that men shouldn't stop using painkillers for fear that it would cut their chances of getting an erection.
