Testicle ultrasound

The testicles are the male reproductive organs that produce sperm and the hormone testosterone. They are located in the scrotum, the flesh-covered sac that hangs between the legs at the base of the penis.

Testicle ultrasound is an imaging procedure that examines the testicles and other parts inside the scrotum. The ultrasound machine sends out high-frequency sound waves, which reflect off areas in the scrotum to create a picture.

There is no ionizing radiation exposure with this test. Ionizing radiation procedures such as x-ray carry a small cancer risk and may damage sperm, but this test does not.
