Medical Research: What is the background for this study? What are the main findings?

Dr. Lopez: Coffee, and its most studied component, caffeine, have been implicated in potential health benefits due to the rich sources of antioxidants and anti-inflammatory compounds contained in this beverage.

Caffeine intake reduced the odds of prevalent erectile dysfunction, especially an intake equivalent to approximately 2-3 daily cups of coffee (170-375 mg/day). This reduction was also observed among overweight/obese and hypertensive men, but not among diabetic men. These associations are warranted to be investigated in prospective studies.

Medical Research: What should clinicians and patients take away from your report?

Dr. Lopez: We only found an association here; therefore, we can’t infer causality nor give any clinical recommendation at this moment. However, this is a good foundation to continue investigating the effects of caffeine intake on urological health outcomes, mainly in the conduct of prospective studies.

Medical Research: What recommendations do you have for future research as a result of this study?

Dr. Lopez: Next two steps: First, we need to conduct prospective studies to determine if indeed caffeine intake can prevent the development of erectile dysfunction. The second step is to seek funding to conduct these prospective studies.
