Testicular Biopsy

Biopsy, Testicular

Results

A testicular biopsy is a test in which a small sample of tissue is taken from one or both testicles 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.
