What Is Erectile Dysfunction? What Causes Erectile Dysfunction?

Erectile Dysfunction (ED) can be a physical problem. Normally, when a man is sexually excited, his penis fills with more blood than usual and it becomes erect or hard. When a man has ED, his penis does not fill with enough blood to get erect or hard. Or it may not stay erect long enough to complete sex.

Many men have this health problem. In fact, about 30 million men in the United States have ED to some degree. And studies show that about half of the men between the ages of 40 and 70 have ED to some degree.
What causes ED?
There are many reasons why a man may develop ED. Despite the common myth, ED is not simply a result of aging. It is more likely to be caused by an underlying health problem.

* high blood pressure
