Exercise is not only good for your heart, but also good for your sexual function. American researchers found that regular and moderate exercise can prevent impotence.
Dr. Owen Goldstein of the Boston University School of Medicine and his researchers found through a large long-term study that men who consumed at least 200 calories per day through exercise were less impotent than men who were less active, and the amount of exercise was equivalent to "exercising" a can of coke, about two miles of brisk walking.
For more than nine years, Dr. Goldstein and his colleagues tracked and investigated 600 men who did not have impotence at first. They observed the factors related to impotence in these men's lifestyle - smoking, severe alcoholism, too little exercise and obesity. They found that the risk of impotence was very low for people who had been active on the exercise field or started exercising during the study period.
Dr. Goldstein wrote in the recently published Journal of Urology: "This discovery is of great significance. Men can reduce the risk of impotence even when they start exercising in middle age.". The mechanism of exercise to prevent impotence is the same as that of preventing heart disease. Impotence and heart disease are both caused by insufficient blood flow in one organ of the body. Exercise helps to smooth blood vessels. Moreover, impotence may actually be an early warning signal of cardiovascular disease, because the penis is more sensitive to the reduction of blood flow than the heart.
