    Testicular Ultrasound

    A testicular ultrasound (sonogram) is a test that uses reflected sound waves to show a picture of the testicles and scrotum camera.gif. 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.
