WHAT IS TESTICULAR ULTRASOUND?
A testicular ultrasound (sonogram) is a test that uses reflected sound waves to show a picture of the testicles and scrotum. 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 hand-held 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.
