Abstract

Little has been explored about testicular and epidi-dymal changes in dogs in different Brazilian regions and their influence on canine fertility, mainly in mongrel dogs. This study was performed to verify the prevalence of testicular and epididymal histopathological changes in mongrel adult dogs from São João da Boa Vista (SP) region, as well as the frequency according to animal size and occurrence of simultaneous testicular and epididymal lesions. The use of mongrel dogs was based on the fact that it is the most common breed in the Brazilian canine popula-tion. Testicles and epipidymis were obtained from 60 adult dogs, between 3 and 6 years old, in castration campaign and sorted to in small breed (28 animals), medium breed (28 animals) and large breed (14 animals). Histopathological evaluation of the 120 testicles showed 107 cases of degeneration, 89 of tubular atrophy, 16 of hipoplasia, 6 of orchitis, 3 leydig cell tumor, 2 normal tissue, one sertolli cell tumor and one case of edema. In the epididymal evaluation, 55 were considered normal, 36 inflammatory, 22 papillary hyperplasia, 14 degenerations, 12 cribriform hyperplasia, 3 cases of fibrosis, one edema, one adeno-miosis and one spermatic granuloma. Testicular and epididymal lesions were more frequents in medium and large breeds. Cribriform epididymal hyperplasia was observed and papillary epididymal hyperplasia for papillary epithe-lial projections with normal morphology in the lumen was proposed.
