What causes erectile dysfunction?

A drop in sexual function rarely has a single cause. Psychological and physical issues often combine to create the problem.

In this video, you’ll learn:

  • Some of the psychological or mental contributors to erectile dysfunction include:
    • Performance anxiety
    • A strange relationship
    • Lack of sexual arousal
    • Depression
  • Physical or organic contributors to erectile dysfunction include:
    • Neurological issues
      • Parkinson’s syndrome
      • Alzheimer’s disease
      • Stroke
      • Spinal cord injury
    • Low testosterone level
    • Blood flow issues
      • High blood pressure
      • High cholesterol
    • Tobacco use
    • Diabetes
    • Radiation to the pelvis
    • Veno-occlusive dysfunction, which allows blood to flow out of the erectile tissue during an erection
  • The psychological and physical causes of decreased sexual function are difficult to separate. If you feel anxious or depressed, those feelings are actually chemical reactions. So those are also a type of physical issue.
