Moderate exercise may help prevent impotence, or as it has come
to be known thanks to the makers of Viagra, erectile dysfunction,
according to researchers.
In a large, long-term study, researchers found that men who
burned at least 200 calories a day through exercise were less likely
than inactive men to become impotent.
- They found that men who had been active to begin with, as well
as those who took up exercise during the study period, were at
lower risk of experiencing impotence.
Exercise may ward off impotence for the same reasons it can
prevent heart attacks, by keeping blood vessels clear.
In fact, impotence can be an early warning
sign of coronary artery disease, since the penis is more
sensitive to slow-downs in blood flow than the heart is, noted researchers.
Impotence affects about one quarter of American men by the age
of 65, and there is no cure.
