Testicular Ultrasound


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

Testicular ultrasound

The testicles are normal in shape and size and are in the normal position.

There is no evidence of a noncancerous (benign) or cancerous (malignant) lump in the testicles.

There is no evidence of infection or inflammation of the testicles or epididymitis.

There is no twisting of the spermatic cord, cutting off blood supply to the testicles (testicular torsion).

There is no sign of fluid in the scrotum (hydrocele), blood in the scrotum (hematocele), fluid in the epididymis (spermatocele), or pus in the scrotum (pyocele).


A lump is present in the testicle or there are signs of a recurrent testicular cancer.

Signs of infection or inflammation of the testicles or epididymis is present.

The spermatic cord is twisted, cutting off blood supply to the testicles (testicular torsion).

None or only one testicle is present in the scrotal sac.

Fluid (hydrocele), blood (hematocele), or pus (pyocele) is present in the scrotum or fluid is present in the epididymis (spermatocele).

There is a hernia in the scrotum.

What Affects the Test

Reasons you may not be able to have the test or why the results may not be helpful include:

  • Not being able to remain still during the test.
  • Having an open sore or wound in the area that needs to be viewed.

What To Think About

  • Testicular ultrasound is usually done to evaluate a mass or pain in the testicles for possible cancer. Young men with a testicular mass or pain should be evaluated immediately by a doctor. Testicular cancer is the most common cancer in young men.
  • With testicular ultrasound, your doctor can usually tell the difference between a fluid-filled cyst, a solid lump, or another type of mass.
    • A fluid-filled mass that has a symmetrical shape and does not have particles floating in it is likely to be a cyst or a hydrocele.
    • A mass that does not have fluid, one that has fluid with floating particles (atypical cyst), or one that is larger than expected needs further evaluation. Often a follow-up ultrasound is done in 6 to 8 weeks to allow time for the mass to go away on its own.
    • If a solid lump or an atypical cyst is present and a testicular ultrasound cannot determine whether it is cancer, a biopsy may be recommended.
