According to a research from Health Science Center of the University of Texas, Houston, published in April 2015 men who drink two to three cups of coffee per day are less likely to have erectile dysfunction

Caffeine is consumed by more than 85% of adults and we did not know its effect on erectile dysfunction. This study investigated the association between caffeine consumption and erectile dysfunction. Data from 3724 men aged over 20 years (and who participated in a National Survey of American health (NHANES)) were analyzed. The questionnaire asked about how much they had consumed over the past 24 hours. The study found that men who consumed between 2 to 3 cups of coffee a day (85-170 milligrams of caffeine) were 42 percent less likely to suffer from erectile dysfunction. This reduction was also observed in overweight patients, obese and hypertensive patients but not in patients with diabetes, the leading cause of erectile dysfunction. The exact physiology of this effect is unknown, but researchers think that caffeine’s effect on the body includes relaxing the helicine arteries, which in turn improves blood flow in the penis.

Opinion of the author

The study is weak evidence.  It must be confirmed in prospective studies, that is, when the exposure is measured before the occurrence of the event studied. Caffeine sources on the survey included energy drinks and soda who are are extremely unhealthy.
Caffeine intake equivalent to 2 to 3 cups of daily coffee appears to be have neutral or beneficial health effects in most people but sugar-free. However, excess caffeine can cause symptoms (sleep disruptions, headaches, anxiety and palpitations). — strong or rapid heartbeats.
Finally, if you have erectile dysfunction, see your doctor for advice and treatment options.
