Intrigued? Ok, reports out of the University of Texas Health Science Center in Houston confirmed previous findings mainly that consumption of the world’s number one stimulant, caffeine is also correlated with lower levels of erectile dysfunction in US men.
Specifically, men that consumed 85-170 mg/day and 171-303 mg/day of caffeine where 42% and 39% less likely to report ED compared to those who drank minimal caffeine (0-7mg) respectively. Furthermore, these results where not just experienced in healthy men, overweight and hypertensive (high blood pressure) males still exhibited a similar trend, with the only exception being men with diabetes.
The mechanism behind this finding? Caffeine has specific vasodilatation properties that can increase blood flow to the tissues in question – specifically the penile helicon arteries and the cavernous smooth muscle in the cavernosal spaces.
To put the amount of caffeine into context, 2-3 cups of coffee, 2-3 espressos or one medium Starbucks drip coffee would all fall into the range outlined above to seek the benefits. However, since ED is a multifactorial disease, the authors caution against significantly altering medical practice in response to their findings. In the meantime, go grab a cup of Jo.
