Erectile Dysfunction

Diagnosis

In many cases, ED indicates of some other underlying disorder such as diabetes or high blood pressure. For this reason, the first and most important component in the treatment of ED is proper examination and diagnosis. Mayo urologists work closely with endocrinologists, cardiologists and other specialists to assess the nature of the patient's ED.

Gathering a complete history of the condition is the first step toward proper diagnosis. Blood tests help physicians determine the level of male hormones and other medical problems. RigiScan and other tests also help to monitor erections during sleep in order to differentiate psychological from physical causes.

The following tests may be used to help diagnose ED:

  • Ultrasonography helps to determine whether there is a problem with blood flow to the genitals.
  • Neurologic evaluations, accomplished through a physical examination, help urologists determine if there is genital nerve damage.
  • Cavernosometry tests the vascular pressure of the penis.
  • Cavernosography uses an injectable dye to search for blood flow problems in the penis.
