A study recently published in The Journal of Sexual Medicine has shown that men who did aerobic exercise, typically for 30 to 60 minutes three to five times a week, had statistically significant improvements in erectile function compared with those who did not exercise. The benefit of exercise could be seen in men irrespective of the severity of their erectile dysfunction.
Exercise improves cardiovascular health, helps to reduce body weight, lowers blood pressure, and also improves blood sugar control in diabetic patients. Exercise could improve blood vessel function, increase testosterone levels and reduce inflammation. All these may help explain why exercise can improve erectile function.
The effect of other lifestyle modifications which could also influence the outcome of the study, such as diet modification, could not be assessed.
Nonetheless, regular aerobic exercise can be a low-risk and effective treatment to improve erectile function. Before starting on an exercise programme, if in doubt please check with your doctor if it is safe for you.
