Heart Health Shows in Erectile FunctionThe cardiovascular system is responsible for erectile function, so problems with circulation and heart disease often show up early as erectile dysfunction. Exercise, especially cardiovascular exercise such as walking, running, biking, reduces the risk of heart disease and maintains circulation.
Most Men at Risk for Erectile DysfunctionThe large study included over 31,000 men who did not have prostate cancer, aged 53-90. One third of the men reported having erectile dysfunction in the previous three months. The risk goes up 5% for each year after age 50. The study showed that regular exercise can mean 10 more years free of erectile dysfunction for the average man. Previous studies have found exercise reduces the risk of prostate cancer. Treatment of prostate cancer can result in erectile dysfunction, so preventing prostate cancer could reduce the incidence of impotence.
Other Risk Factors You Can ChangeBesides inactivity, other risk factors that men can change include obesity and smoking. Men can greatly reduce their risk of erectile dysfunction by regular cardiovascular exercise, losing weight, and not smoking.
