How is cryptorchidism and testicular atrophy?

➢ Atrophic, small residual tubules with no spermatogenesis, and pale surrounding stroma. ➢ A cryptorchid testis fails to develop normal spermatogenesis unless placed in the scrotum, because deterioration leading to the appearance shown begins by age 2. ➢ If unilateral, spermatogenesis in the remaining normal testis may prevent infertility. Cryptorchidism carries an increased risk for testicular carcinoma in either testis. ➢ Leydig cells (not shown here) still retain their function.
