Good news, dudes: You may be able to stave off impotence with an extra cup of Joe, according to a new study. Men who consume more caffeine — the sweet spot seemed to be two to three cups of coffee a day — had a lower risk of erectile dysfunction compared to men who consume little to no caffeine per day.
If you're not a big coffee drinker, the caffeine used in the study included tea, soda and sports drinks as well. Researchers believe caffeine relaxes certain arteries and muscles in the penis, which improves blood flow and the ability to have an erection.
