What causes erectile dysfunction?

ANSWER

It results from decreased blood flow to the penis. In older men it's usually because vessels that supply blood to the penis have narrowed with age. Emotional issues are more often the problem for younger men.

Also, just about any medical condition that affects your nerves or blood vessels could hurt your ability to have erections. High blood pressure, heart disease, multiple sclerosis, and diabetes can all lead to ED. In fact, over 50% of men with diabetes have problems with ED.

Other causes include:

  • Hormonal issues like low testosterone levels -- this is common with older men
  • Prostate cancer treatments, including surgery and radiation
  • Stress, anxiety, and depression
  • Medications like blood pressure drugs (especially beta-blockers) and certain antidepressants
