Testicular biopsy - Results

Alternative Names

Biopsy - testicle

Normal Values:

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:

Your health care provider should explain and discuss all abnormal results with you.
