Abstract: The objective of this study was to assess macroscopic and microscopic characteristics of the testes in unilaterally cryptorchid dogs (n=16 and n=13, respectively). An additional goal was to measure and compare plasma levels of testosterone between the cryptoid (n=13) and control dogs (n=16). The size and weight of the retained tested were lower (P <0.01) compared with the descended testes in the unilaterally cryptoid dogs of different breeds, but there was no difference between the inguinal and abdominal cryptoid testes (P >0.01). Spermatogenesis was significantly suppressed in the cryptorchid testes compared with the contralateral testes of the unilaterally cryptorchid dogs. The number of Leydig cells was higher (P <0.01) in the cryptorchid than in scrotal testes. Plasma concentration of testosterone did not vary (P >0.1) between the cryptoid and control dogs. Normal endocrine function could be maintained in the cryptorchid dogs, despite the smaller testicular size of the retained testes.
