A penile ultrasound is a diagnostic test that uses high-frequency sound waves to create images of the structures inside the penis. It’s a non-invasive test that can help diagnose the cause of erectile dysfunction (ED) and other penile conditions.

During a penile ultrasound, a handheld device called a transducer is placed on the skin of the penis. The transducer sends out sound waves that bounce off the structures inside the penis and create an image on a computer screen. The images can show the blood flow to the penis and the function of the nerves that control erections.

Penile ultrasound is typically used to diagnose the cause of ED when other tests, such as blood tests or physical exams, are inconclusive. It can help identify problems with blood flow, such as arterial blockages or venous leaks, which can contribute to ED. It can also help diagnose Peyronie’s disease, a condition that causes scar tissue to develop inside the penis and can lead to curvature and pain during erections.

Penile ultrasound is generally considered safe and has few risks. Some men may experience mild discomfort or a slight burning sensation during the procedure, but this usually goes away quickly. If you’re considering a penile ultrasound, talk to your healthcare provider about what to expect during the procedure and any potential risks or complications.
