title: [Polyorchidism with undiscending testis: a case report].
abstract: We report here the 21st case of polyorchidism in Japan. A 3-year-old boy with left undiscending testis was referred to our hospital for orchiopexy. At surgery, the undiscending testis was identified as two testes. We performed left orchiopexy, because these tests had no malignancy.
