Tests and diagnosis

By Mayo Clinic Staff

A physical exam is often sufficient to identify the presence of scar tissue in the penis and diagnose Peyronie's disease. Rarely, other conditions cause similar symptoms and need to be ruled out.

Tests to diagnose Peyronie's disease and understand exactly what's causing your symptoms might include the following:

  • Physical exam. Your doctor will feel (palpate) your penis when it's not erect, to identify the location and amount of scar tissue. He or she might also measure the length of your penis. If the condition continues to worsen, this initial measurement helps determine whether the penis has shortened.

    Your doctor might also ask you to bring in photos of your erect penis taken at home. This can determine the degree of curvature, location of scar tissue or other details that might help identify the best treatment approach.

  • Other tests. Your doctor might order an ultrasound or other tests to examine your penis when it's erect. Before taking images of your penis, you'll likely receive an injection directly into the penis that causes it to become erect.

    Ultrasound is the most commonly used test for penis abnormalities. Ultrasound tests use sound waves to produce images of soft tissues. These tests can show the presence of scar tissue, blood flow to the penis and any other abnormalities.
