SNYDER Keywords: testis; biopsy; cryptorchidism Abstract: Testicular biopsy (TBx) performed during orchiopexy in boys with cryptorchidism can help to predict future semen analyses and possibly identify patients at risk for testicular cancer. It has been theorized that TBx can be detrimental to the long-term health of the testis. We examined testicular microlithiasis (TM) and antisperm antibody (ASA) production in cryptorchid TBx.
