Erectile dysfunction, or ED, is the inability to achieve or sustain an erection suitable for sexual intercourse. Causes include medications, chronic illnesses, poor blood flow to the penis, drinking too much alcohol, or being too tired.
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 also can be a sign of an underlying health condition that needs treatment and a risk factor for heart disease down the road.
