Testicular Biopsy


A testicular biopsy is a test in which a small sample of tissue is taken from one or both testicles camera.gif and examined under a microscope to evaluate a man's ability to father a child. Results are usually available in 2 to 4 days.

A pathologist examines the biopsy sample through a microscope for any abnormalities in sperm production or maturation. If sperm development appears normal yet a semen analysis test shows reduced or absent sperm, a blockage of the tube (vas deferens) from the testes to the urethra is suspected. A blocked vas deferens can sometimes be repaired by surgery.

What Affects the Test

It is important to remain completely still while a biopsy is done under local anesthesia. If this is not possible, general anesthesia may be needed.

What To Think About

Testicular cancer is more likely to spread when a testicular biopsy is done. For this reason, a biopsy usually is not done if testicular cancer is suspected. A testicular ultrasound is generally done to help diagnose suspected testicular cancer. To learn more, see the topic Testicular Ultrasound. When cancer is suspected, an open surgical procedure (orchiectomy) is done to confirm the diagnosis.
