Definition & Facts
Erectile dysfunction (ED) is a condition in which you are unable to get or keep an erection firm enough for satisfactory sexual intercourse. You may find it difficult to talk with a health care professional about ED. However, remember that a healthy sex life is part of a healthy life.
Symptoms & Causes
Symptoms of erectile dysfunction (ED) include being able to get an erection sometimes, but not every time; being able to get an erection but not having it last long enough for sexual intercourse; and being unable to get an erection at any time.
A doctor diagnoses erectile dysfunction (ED) with a medical and sexual history and a mental health and physical exam. You may find it difficult to talk with a health care professional about ED; however, remember that a healthy sex life is part of a healthy life.
A health care professional may work with you to treat an underlying cause of your erectile dysfunction (ED). Choosing an ED treatment is a personal decision.
You can help prevent many of the causes of ED by adopting healthy lifestyle behaviors, such as being physically active, quitting smoking, and following a healthy eating plan.
