Caffeine Makes You Hard

Caffeine, found in coffee, chocolate, tea and supplements, increases strength, power and endurance. It might also improve sexual performance. David Lopez from the University of Texas-Houston School of Public Health, and co-workers, found that men who consumed the most caffeine showed the lowest risk of erectile dysfunction. The researchers examined more than 3,700 men who participated in the National Health and Nutrition Examination Survey (NHANES). The data was obtained from 24-hour dietary recall and was consistent among lean and obese men. However, the relationship did not exist in men with type 2 diabetes. Caffeine might improve athletic and sexual performance. (PLoS ONE, 10(4): E0123547, 2015)
