Researchers found that among the more than 1,300 men they followed, those who smoked were at greater risk of erectile dysfunction (ED) than either former smokers or non-smokers.
Smokers in their 40s, the youngest group in the study, showed the highest smoking-related risk. Compared with other men their age, they were nearly three times more likely to have erectile dysfunction. Smoking was also linked, to a lesser extent, to impotence among men in their 50s and 60s, but not among those in their 70s.
