Testicular biopsy is surgery to remove a piece of tissue from the testicles. The tissue is examined under a microscope.

How the Test is Performed
The biopsy can be done in many ways. The type of biopsy you have depends on the reason for the test. Your health care provider will talk to you about your options.
Open biopsy may be done in the health care provider's office, a surgical center, or at a hospital. The skin over the testicle is cleaned with a germ-killing (antiseptic) medicine. The area around it is covered with a sterile towel. A local anesthetic is given to numb the area.
A small surgical cut is made through the skin. A small piece of the testicle tissue is removed. The opening in the testicle is closed with a stich. Another stitch closes the cut in the skin. The procedure is repeated for the other testicle if necessary.
Needle biopsy is most often done in the health care provider's office. The area is cleaned and local anesthesia is used, just as in the open biopsy. A sample of the testicle is taken using a special needle. The procedure does not require a cut in the skin.
Depending on the reason for the test, a needle biopsy may not be possible or recommended.
