According to a new study, ‘men who drink the equivalent caffeine level of two to three cups of coffee a day are less likely to have erectile dysfunction.’

Yep. Caffeine builds strong d***s.

The study, released this week by the University of Texas Health Science Center in Houston, found that men who consumed between 85 and 170 milligrams of caffeine a day were 42 per cent less likely to report erectile dysfunction, than those who didn’t consume any.


Men who consumed between 171 and 303 milligrams of caffeine a day were 39 per cent less likely to report performance issues.

The study used data from the National Health and Nutrition Examination Survey, where erectile dysfunction was assessed by a single question. Caffeine sources in the study included tea, soda and sports drinks, as well as coffee.



But how does it work? Well, the caffeine makes the muscles in the penis more relaxed, and those relaxed peen muscles mean increased blood flow and, boom, stronger erections.

Or, as the researchers put it: ‘the suggested biological mechanism is that caffeine triggers a series of pharmacological effects that lead to the relaxation of the penile helicine arteries and the cavernous smooth muscle that lines cavernosal spaces, thus increasing penile blood flow.’

Now you know what to get the BF for his birthday – Starbucks gift card.
