At one time, doctors thought erectile dysfunction was primarily caused by psychological issues. But this isn't true.

Erectile dysfunction (ED) is the inability of a man to maintain a firm erection long enough to have sex. Although erectile dysfunction is more common in older men, this common problem can occur at any age. Having trouble maintaining an erection from time to time isn't necessarily a cause for concern. But if the problem is ongoing, it can cause stress and relationship problems and affect self-esteem.

Erectile dysfunction (ED) is when a man has trouble getting or keeping an erection. ED becomes more common as you get older. But male sexual dysfunction is not a natural part of aging.
