ultrasound (sonogram) is a test that uses reflected
sound waves to produce a picture of the
scrotum. An ultrasound can show the long, tightly
coiled tube that lies behind each testicle and collects sperm (epididymis) and
the tube (vas deferens) that connects the testicles to the
prostate gland. The ultrasound does not use
X-rays or other types of radiation. See a picture of
the male reproductive system .
A small handheld instrument called a
transducer is passed back and forth over the scrotum. The transducer sends the
sound waves to the computer, which converts them into a picture that is
displayed on a video monitor. The picture produced by ultrasound is called a
sonogram, echogram, or scan. Pictures or videos of the ultrasound images may be
saved as a permanent record.
