Drinking 2 to 3 cups of coffee a day would lower the risk of suffering from erectile dysfunction (also called erectile dysfunction) in 42% of men. All men seem to benefit from the beneficial effects of coffee, except those with diabetes. In France, it is estimated that around 3 million men suffer from erectile dysfunction.
Researchers at the University of Texas Health Science Center in Houston analyzed data from more than 3,700 men from the National Health and Nutrition Examination Survey.
For this research, the men had to answer a questionnaire about their caffeine consumption during the last 24 hours. To assess possible erectile dysfunction, the researchers asked each participant a single question during an interview conducted with the help of a computer.
2 to 3 cups of coffee a day
Compared to men who consumed 0 to 7 mg of caffeine per day, those who ingested between 85 and 170 mg of caffeine per day, or 2 to 3 cups of coffee, saw their risk of suffering from erectile dysfunction decrease by 42%.
Those who consumed between 171 mg and 303 mg of caffeine per day had a 39% lower risk of suffering from erectile dysfunction compared to those who only took between 0 and 7 mg of caffeine.
The study was not limited to coffee, but also included other caffeine-rich drinks such as sodas (eg cola), tea and energy drinks.
Diabetes, a serious risk factor
Despite the fact that researchers observed a reduction in the prevalence of erectile dysfunction in obese, overweight and high blood pressure men, this was not the case in diabetic patients. Diabetes is one of the main risk factors for erectile dysfunction.
The researchers, however, failed to show a causal link, they found a correlation between erectile dysfunction and caffeine consumption. Further research will therefore be necessary to prove or not a possible link of cause and effect.
A possible cause of the caffeine effect, according to this publication, could come from a relaxation of the muscles and arteries in the penis, which promotes erection.
Coffee has multiple positive effects on health
Coffee, consumed in a reasonable dose, that is to say 2 to 5 cups a day, can be excellent for the prevention of many diseases such as cancer, hypertension, depression or type 2 diabetes. .
A study carried out by Johns Hopkins University, (USA), showed that people who consumed 3 to 5 cups of coffee a day saw their arteries more protected against blockages than those who did not consume coffee.
A study published at the end of 2012 showed the effectiveness of ginseng in the fight against mild to moderate erectile dysfunction. It is the only plant, with now coffee, to present a scientifically proven effect (or partially) to fight against this male disease.
