Testicular Ultrasound

How It Is Done continued...

Before the test, you will need to take off all your clothes from the waist down. You will put on a gown. You will be asked to lie on your back on a padded table. Folded towels will be used to cover the penis and lift the scrotum. A gel (such as K-Y Jelly) will be spread on your scrotum. This is used for the transducer, which is pressed against your skin and moved across your scrotum many times.

You will need to lie very still during the ultrasound scan. You may be asked to take a breath and hold it for several seconds during the scan. The test takes about 20 minutes.

When the test is finished, the gel is removed from your skin. You may be asked to wait until the radiologist has reviewed the test. He or she may want to do more ultrasound views.

How It Feels

The gel may feel cold when it is put on your scrotum. Or it may be warmed to body temperature first. You will feel light pressure from the transducer as it passes over your scrotum. If the test is being done to find out how bad damage is from a recent injury or to find out what is causing pain in the testicles, the slight pressure of the transducer may be a bit painful. You will not hear the sound waves.

If a biopsy is done during the ultrasound, you may have slight discomfort when the sample is taken.


There are no known risks from a testicular ultrasound test.
