Researchers found that the men who had two cups of coffee were 42 percent less likely to suffer from erectile dysfunction. The number even dropped to 39 percent for men who had three cups of coffee.
In the United States, 18.4 percent of men 20 years and older have ED, suggesting that more than 18 million men are affected. Caffeine is consumed by more than 85 percent of adults, according to previous research.
Researchers are form the University of Texas and nearly 4,000 men participated in the study.
It was also noted that the effect was not different regardless of whether the subject was overweight, obese or had high blood pressure.
It was even noted that there was reduced effect of coffee on men who had diabetes, as those who suffer from diabetes generally have high risk of erectile dysfunction.
The information was derived from the National Health and Nutrition Examination Survey.
The medical condition of erectile dysfunction was derived from one specific question that was part of a computer assisted interview.
“Even though we saw a reduction in the prevalence of erectile dysfunction with men who were obese, overweight and hypertensive, that was not true of men with diabetes,” said David Lopez, a professor at University of Texas, Houston, Texas.
Researchers said that caffeine in coffee sets off a chain of pharmacological effects that increase a man’s blood flow to his penis by relaxing various arteries as well as the muscle.
Another research discovered that drinking coffee can increase a women’s sex drive.
Another research team discovered that caffeine raised female libido in female rats by stimulating the section of rodents brain that controlled arousal.
The Texas research team concluded that a similar effect to the one above can be recreated in human beings who did not drink coffee on a regular basis.
