All of the following can be done EXCEPT -Testicular biopsyChest x-rayInguinal explorationCT abdomen  <response>: A testicular biopsy more specifically a trans-scrotal testicular biopsy is not done, rather is contraindicated.A suspected scrotal mass is investigated by ultrasonography on finding a testicular mass, a radical inguinal orchiectomy is done. A trans-scrotal testicular biopsy would breach anatomical barriers and would spread the tumor.
