Testicular biopsy is surgery to remove a piece of tissue from the
Biopsy – testicle
How the test is performed
The biopsy can be done in many ways. What 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, and a small piece of the testicle tissue is removed. A stitch is used to close the opening in the testicle. Another stitch closes the cut in the skin. If necessary, the procedure is repeated for the other testicle.
Needle biopsy is usually 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 that does not require a cut in the skin.
Depending on the reason for the test, a needle biopsy may not be possible or recommended.
How to prepare for the test
As a general rule, you should not take aspirin or medications that contain aspirin for 1 week before the procedure. Ask your doctor before stopping any medications.
How the test will feel
There will be a sting when the anesthetic is given.You should only feel pressure or discomfort similar to a pin prick during the biopsy.
Why the test is performed
The test is usually done to find the cause of male
Testicle biopsy may also be done if you have found a lump during
A biopsy to determine whether the lump is cancerous or noncancerous (benign) may be done. If it is cancerous or cancer is suspected, the entire testicle is removed.
Sperm development appears normal.
What abnormal results mean
Abnormal results may mean a problem with sperm or hormone function. Biopsy may be able to find the cause of the problem.
If the sperm development appears normal in the testicle, but semen analysis shows no sperm or reduced sperm, there may be a blockage of the tube through which the sperm travel from the testes to the urethra. This blockage can sometimes be repaired with surgery.
Other causes of abnormal results:
A cyst-like lump filled with fluid and dead sperm cells (spermatocele)
Your health care provider should explain and discuss all abnormal results with you.
What the risks are
There is a slight risk of bleeding or infection. The area may be sore for 2 – 3 days after the biopsy. The scrotum may swell or become discolored. This should clear up within a few days of the procedure.
Your health care provider may suggest that you wear an athletic supporter for several days after the biopsy. You will probably be asked to avoid sexual activity for 1 – 2 weeks.
Keep the area dry for several days after the procedure.
Continue to avoid using aspirin or medications that contain aspirin for 1 week after the procedure.
