A testicular ultrasound (sonogram) is a test that uses reflected sound waves to show a picture of the testicles and scrotum . The test can show the long, tightly coiled tube that lies behind each testicle and collects sperm (epididymis). And it can show the tube (vas deferens) that connects the testicles to the prostate gland. The ultrasound does not use X-rays or other types of radiation.
A small handheld device called a transducer is passed back and forth over the scrotum. The device sends the sound waves to the computer, which turns them into a picture. This picture is shown on a video screen. The picture produced by ultrasound is called a sonogram, echogram, or scan. Pictures or videos of the ultrasound images may be saved.
