Those with a waistline measuring 42 inches were nearly twice as likely to suffer as men with a 32-inch girth, a meeting of the American Urological Association heard. The study, funded by the National Cancer Institute, the National Heart Lung and Blood Institute and the American Cancer Society, also found that inactive men were more likely to suffer erectile dysfunction than men who exercised for at least 30 minutes a day. Erectile dysfunction, commonly known as impotence, is a consistent inability to gain or sustain an erection. The risk factors for erectile dysfunction are basically drinking too much, smoking and being overweight.
Alcohol is particularly important.
Diabetics were also at risk.
