I hear that exercise and oysters are the key to men's sexual health. Oysters, I read, are high in zinc, and the male body needs zinc in order to make sperm. And exercise helps men make more testosterone and keep their system running in optimal shape.

    

A German study from Cologne University Medical Center has found that physical exercise can be as effective as Viagra in dealing with erectile dysfunction. Over 80% of their participants with mild to medium circulatory problems reported better erections compared to 74% taking Viagra.

Get a heart workout. Your heart is most important muscle in your body and you must keep it in shape. It is this organ that you start with to build up your levels of stamina and strength. One of the most effective ways to do that is do regular aerobic exercise. That is exercise that works the large muscle groups. Cycling, swimming, stepping, brisk walking are the easiest and cheapest.

Oyster seems to be a myth but exercise is likely to be good.
