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. For instance, a minor physical condition that slows your sexual response might cause
anxiety about maintaining an erection. The resulting anxiety can lead to or worsen erectile dysfunction.
Psychological causes of erectile dysfunction
The brain plays a key role in triggering the series of physical events that cause an erection, starting with feelings of sexual excitement. A number of things can interfere with sexual feelings and cause or worsen erectile dysfunction. These include:
Depression, anxiety or other mental health conditions
Stress
Relationship problems due to stress, poor communication or other concerns
