OK, it takes a bit more than coffee for anything interesting to happen, but coffee does appear to help stave off erectile dysfunction, according to researchers at the University of Texas School of Public Health. Note use of the word “appear.” That’s because, while the research shows that men who consume more caffeine each day had a lower risk of erectile dysfunction, the scientists stop short of claiming any cause-and-effect relationship. HealthDay reports that the researchers studied data from more than 3,700 men, focusing on their caffeine consumption, and their self-reported (seriously) incidences of erectile dysfunction. The envelope please….The researchers found that compared to men who consumed zero to 7 milligrams of caffeine a day, men who consumed 85 to 170 milligrams of caffeine a day were 42 percent less likely to report erectile dysfunction, and those who consumed 171 to 303 milligrams of caffeine a day were 39 percent less likely to report the condition. The bottom line: two to three cups of coffee a day should do the trick.
