Erectile dysfunction can be caused by mental or physical problems, or a combination of both. Men who are depressed or have some other emotional problem may have no interest in having sex. There may also be physical problems with how blood flows into the penis and is kept there during an erection.

What are the signs and symptoms of the condition?

Men with erectile dysfunction have trouble getting and keeping an erection.

What are the causes and risks of the condition?

Erectile dysfunction is a common problem. It is a problem whose frequency increases with age, but it is not necessarily a consequence of aging. Roughly 25% of men over the age of 65 have some degree of ED. Erectile dysfunction is considered a medical problem if it lasts more than 3 months.
