Mehmet Oz, MD, Cardiology, answeredPenile ultrasound is a non-invasive way to help diagnose the specific cause of a man's erectile dysfunction (ED). A natural compound is injected into the penis that causes an erection, and the ultrasound registers blood flow, signs of vascular illness, and any scarring. This helps your doctor figure out if your ED is caused by a physical condition such as cardiovascular illness. It can be very useful for young men whose ED was caused by an accident or trauma, to determine whether surgery would be beneficial. It is sometimes used in men for whom drugs for ED aren't working well, to help determine why.

Penile ultrasound uses high frequency sound waves to image blood vessels and tissues in the penis to diagnose erectile dysfunction (ED) caused by a medical condition that decreases blood flow to the penis needed for an erection.
An ultrasound scan can show whether blood vessels have become leaky or are narrowed because of cardiovascular (heart and vessel) disease, as well as whether there is hardened scar tissue in the penis (a condition known as “Peyronie’s disease”) that can interfere with an erection. The test is done while the penis is flaccid and when it’s erect (you are usually given a drug that causes an erection).
