Avaliação das principais lesões testiculares de cães sem raça definida na região de Uberlândia - MG

Abstract

The dog’s relevance in the society is increasing and that is why it is important to study their reproductive diseases. This study aims to obtain information about prevalence of testicular lesion in neutered dogs at Veterinary Hospital of the Federal University of Uberlândia, MG. For this experiment we used testicles of mixed-breed dogs, which were collected in the sterilization project at Federal University of Uberlândia. According to their size, the animals were divided into three groups designated as small dogs, medium dogs and large dogs. The testicles were separated from the epididymis, the testicular measurement was performed obtaining values of length, height, width, volume and weight and the testicle were divided into cranial, medial and caudal regions.. After the processing, the histological analysis of the samples was performed and the lesions that were found were degeneration, atrophy, focal hypoplasia, fibrosis and interstitial edema. The occurrence of degeneration and atrophy was the same for the three groups of dogs. The occurrence of fibrosis was higher in large dogs, while hypoplasia and edema were more frequent in small dogs. In general, there was a greater impairment of the medial and caudal regions of the testicles. In addition to this study, more researches are needed to compare the obtained data and achieve a better comprehension of this subject.
