Test Overview
A testicular biopsy is a test to remove a small sample of tissue
from one or both
testicles and examined under a microscope to evaluate
a man's ability to father a child.
The
testicles
(testes) are oval-shaped glands that hang in
the scrotum beneath the base of the penis. The testicles produce
sperm
(necessary for reproduction) and male hormones,
such as
testosterone.
