Dec. 27 -- (HealthDay News) -- Erectile dysfunction occurs when a man can't achieve or maintain an erection during sex.

The American Academy of Family Physicians says the condition doesn't have to be a natural part of getting older. ED often is attributed to physical or psychological causes. Physical reasons may include:

  • Having a side effect of surgery on the prostate or bladder, or radiation therapy to the testicles.
  • Having low testosterone levels, kidney failure, liver failure, multiple sclerosis or Parkinson's disease.
  • Having chronic conditions such as diabetes, high blood pressure, or hardening of the arteries.
  • Having had a stroke or an injury to the brain or spinal cord.
  • Using too much tobacco or alcohol.
  • Being tired.
