Definition & Facts
Erectile dysfunction (ED) prevents males from getting or keeping an erection that is firm enough for sex. You may find it uncomfortable talking about ED. But a healthy sex life is part of healthy living. ED is not a routine part of aging.
Symptoms & Causes
Symptoms of 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 sex, and being unable to get an erection at any time.
Diagnosis
Health care professionals diagnose ED with a medical, sexual, and mental health history; a physical exam; and lab and other tests. Talking with a health care professional helps to properly diagnose your ED.
Treatment
Health care professionals treat the underlying causes of ED and then focus on improving sexual function. Choosing an ED treatment is a personal decision.
Prevention
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.
