What is a Doppler ultrasound of the penis?

An ultrasound is an imaging technique that uses ultrasound to visualize internal organs, allowing doctors to examine them more precisely.

The penile ultrasound allows visualizing the cavernous body and the spongy body.

It can then be used to diagnose and monitor the course of several diseases that affect the penis, including erectile dysfunction (ED), plaques (such as those caused by Peyronie's disease), fibrosis, tumors and even cancer.

Men who have erection problems usually have to have a Doppler ultrasound. This examination makes it possible to visualize the blood circulation of the cavernous bodies.

The quality of human erections depends on the blood circulation. When a man is sexually stimulated, the arteries of his penis dilate so that blood can flow into it. This blood allows the penis to stiffen so that the man can have sex. The veins of the penis contract to retain blood. When the man is no longer stimulated or when he ejaculates, the veins dilate again so that the blood can circulate again inside his body.

Many men who suffer from erectile dysfunction have problems with blood circulation. It is possible that their arteries do not dilate enough to allow the flush into their penis, or that their veins do not contract enough to retain the blood inside their penis. Both of these problems can affect the quality of erections.
