HOUSTON, May 24 (UPI) -- A daily dose of caffeine may reduce the odds of erectile dysfunction, according to data from a recently published study.
Researchers analyzed dietary information to estimate the daily caffeine intake of 3,724 men who participated in the National Health and Nutrition Examination Survey.
The study, which was published in PLOS ONE, concluded that men may have a reduced risk for ED if they consume caffeine in daily doses roughly equivalent of two to three cups of coffee -- or 170-375 mg per day.
Specifically, men who drank 171-303 mg of caffeine per day reduced the risk of ED by 39 percent and men who drank a daily 85-170 mg reduced the risk by 42 percent, while those who drank 7 mg or less per day reduced the risk by only 1 percent, according to the study.
Researchers found the same correlation in obese and overweight men, as well as men with high blood pressure, but not in those with diabetes.
The study notes that the results constitute "no evidence for a trend" but adds that "these associations are warranted to be investigated in prospective studies."
