Erectile dysfunction (ED) occurs when a man has consistent and repeated problems sustaining an erection. Without treatment, ED can make sexual intercourse difficult. The problem is reported by 1 in 5 men and that number increases with age.
Erectile dysfunction (impotence) is the inability to get and keep an erection firm enough for sex.
Having erection trouble from time to time isn't necessarily a cause for concern. If erectile dysfunction is an ongoing issue, however, it can cause stress, affect your self-confidence and contribute to relationship problems. Problems getting or keeping an erection can also be a sign of an underlying health condition that needs treatment and a risk factor for heart disease.
