A testicular biopsy is a test to remove a small sample of tissue from one or both testicles and examine it under a microscope to evaluate a man's ability to father a child..
Why It Is Done
A testicular biopsy may, on rare occasions, be done to help determine the cause of male infertility. Testicular biopsy may be done if both of the following are present:
- The man's semen does not have sperm.
- Hormone test results are within the normal range.
