what causes erectile dysfunction
Male sexual arousal is a complex process that involves the brain, hormones, emotions, nerves, muscles and blood vessels. Erectile dysfunction can result from a problem with any of these. Likewise, stress and mental health concerns can cause or worsen erectile dysfunction. Sometimes a combination of physical and psychological issues causes erectile dysfunction.
Erectile dysfunction (ED) occurs when a man is unable to get or sustain an erection firm enough for sexual intercourse. Intermittent ED is common. Many men experience occasional ED. It is generally caused by stress, exhaustion, or similar causes. Occasional ED should not be a cause of 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 also can be a sign of an underlying health condition that needs treatment and a risk factor for heart disease down the road.
