What Causes Erectile Dysfunction?

Speed

Simple Answer

Erectile dysfunction, or ED, is trouble getting or keeping an erection. It becomes more common with age, but it is not a normal part of aging. It can be linked to health problems like clogged blood vessels or nerve damage from diabetes. Lifestyle changes like more exercise, losing weight, or stopping smoking may also help.

What It Means

ED can sometimes be a sign of another health problem that has not been found yet. That is why it matters to tell a doctor about it. Treating the cause may help protect your health.

When to Contact a Doctor

You should talk to your doctor if you have ED. The source says ED can be a sign of health problems, and if you do not get checked, those problems may go untreated.

The source says a doctor can offer several treatments, and for many men the answer may be as simple as taking a pill. It does not give a specific medicine or dose.
