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.

Formerly called impotence, erectile dysfunction was once a taboo subject. It was considered a psychological issue or a natural consequence of growing older. These attitudes have changed in recent years. It’s now known that erectile dysfunction is more often caused by physical problems than by psychological ones, and that many men have normal erections into their 80s.

Although it can be embarrassing to talk with your doctor about sexual issues, seeking help for erectile dysfunction can be worth the effort. Erectile dysfunction treatments ranging from medications to surgery can help restore sexual function for most men. Sometimes erectile dysfunction is caused by an underlying condition such as heart disease. So it’s important to take erectile trouble seriously because it can be a sign of a more serious health problem.

Symptoms

Erectile dysfunction is the inability to maintain an erection sufficient for sexual intercourse at least 25 percent of the time.

An occasional inability to maintain an erection happens to most men and is normal. But ongoing erection problems are a sign of erectile dysfunction and should be evaluated. In some cases, erectile dysfunction is the first sign of another underlying health condition that needs treatment.

Causes

Male sexual arousal is a complex process involving the brain, hormones, emotions, nerves, muscles and blood vessels. If something affects any of these systems — or the delicate balance among them — erectile dysfunction can result.
