## Overview

[edit | edit source]

Biopsy is rarely done in the diagnosis of testicular cancer. However, Inguinal biopsy may be done in the contralateral testis if the ultrasound showed the intratesticular mass, cryptorchid testis, marked atrophy, and suspicious mass. Other indications for testicular biopsy are obstructive azoospermia, testicular sperm extraction and diagnosis of carcinoma in situ of the testis.
