A new study by the University of Texas Health Science Center at Houston published in the journal PLOS ONE specified that coffee’s anti-oxidant impact has the ability to lower the risk of erectile dysfunction, (ED), by 42 %.
The majority of ED cases are caused by physical problems, including high blood pressure, overweight, obesity, diabetes and high cholesterol, though it can also be triggered by psychological issues and it affects more than 18 million men aged 20 or older in the US.
The research participants included 3,724 men aged 20 and older. Of these men, 40.9% were overweight, 30.7% were obese, 51% had high blood pressure and 12.4% were diabetic.
Th caffeine intake was estimated by analyzing 24-hour dietary recall data, gathered from asking participants to report all food and beverages consumed in the past day. The caffeine sources assessed included coffee, soda, sports and energy drinks and tea.
The research findings revealed that three cups a day were sufficient to lower the adverse impact of erectile dysfunction. In addition, higher caffeine intake was also found to reduce risk of ED in men who were overweight or obese and those who had high blood pressure, risk factors for erectile dysfunction. Men who had diabetes were not impacted by the lowered risk.
Caffeine induces a series of pharmacological effects that causes relaxation of both the penile helicine arteries and the cavernous smooth muscle of the penis, increasing blood flow.
