Diagnosis of Erectile Dysfunction (Impotence)
by Ricker Polsdorfer, MD
You will be asked about your symptoms and medical history. A physical exam will be done. This will include an examination of the penis, testicles, and rectum. Be prepared to identify every medication you are taking. Medications account for a large number of erectile dysfunction cases. Expect questions about the frequency, quality, and duration of your erections. Your answers may help determine if the primary cause is physical or psychological in nature.
Tests will help narrow down the cause and may include:
