Non-visible Testis (Cryptorchidism)

External genitals in a toddler with a non-visible testis of the right side. The left testis is visible and palpable in the corresponding scrotum. The right testis is neither visible nor palpable in the scrotum. The diagnosis is cryptorchidism of the right side. First of all, the history and the clinical examination can possibly tell which type of cryptorchidism is present. Because the right scrotum is smaller than the left, the right testis must (if present at all) always lie above the scrotum. Notice the relatively high position of the left testis within the left scrotum.
