My husband had done a sperm count and it was like zero so does he do a testicular biopsy?

See urologist: That depends on the reason or etiology for the azoospermia (i.e. No sperm in ejaculate). An evaluation with a urologist will help determine if an invasive procedure such as a testicular biopsy is warranted.

It depends: A thorough evaluation by a urologist or reproductive endocrinologist may uncover reasons that don't warrant biopsy. We also have tests that can hint at the likelihood of finding sperm on biopsy that may preclude biopsy.
