Definition & Facts for Erectile Dysfunction

What is erectile dysfunction?

Erectile dysfunction (ED) is a condition in which you are unable to get or keep an erection firm enough for satisfactory sexual intercourse. ED can be a short-term or long-term problem. You have ED when you

  • can get an erection sometimes, but not every time you want to have sex
  • can get an erection, but it does not last long enough for fulfilling or satisfactory sex
  • are unable to get an erection at any time

Health care professionals, such as primary care providers and urologists, often can treat ED. Although ED is very common, it is not a normal part of aging. Talk with a health care professional if you have any ED symptoms. ED could be a sign of a more serious health problem.

You may find it embarrassing and difficult to talk with a health care professional about ED. However, remember that a healthy sex life can improve your quality of life and is part of a healthy life overall. Health care professionals, especially urologists, are trained to speak to people about many kinds of sexual problems.
