Erectile Dysfunction Causes
What causes erection problems?
Erection problems may be caused by physical problems related to the blood vessels, nerves, and hormones. Or they may be caused by mental health issues.
Normally, an erection occurs when your imagination or senses (vision, hearing, touch, smell, taste) are stimulated. You then get aroused. Your central nervous system sends nerve impulses that increase blood flow to your penis.
Causes of erection problems may include:
- Problems with the blood vessels. These problems may prevent blood from filling the penis or from staying there long enough to keep an erection.
- Problems with the nerves. These may prevent arousal signals from traveling from the brain and spinal cord to the penis.
- Other health problems, such as low testosterone levels, diabetes, or high blood pressure.
- Side effects of certain medicines.
- Drinking too much alcohol or smoking.
- Surgery, such as for prostate cancer.
- Mental health issues, such as depression, anxiety, stress, or grief.
