Abstract The present study aims to evaluate sonographic parameters (size, echotexture and echogenicity) of the accessory sex glands (vesicular, prostate and bulbourethral glands) of goats submitted to different castration techniques. This methodology aims to simulate pathological conditions similar to those occurring in animals and humans, and has as future implications provide tools which enable the accurate noninvasive diagnosis of diseases of these glands. To this end, ten adult male goats will be used, which will submitted to castration procedures: (i) in five animals will be employed conventinal surgical technique (bilateral orchidectomy), and (ii) in the others five animals will be employed the crushing vessels technique (Burdizzo). In the castrations day, the males will also be evaluated by ultrasound exams (B-Mode) in order to determine the dimensions and attributes ultrasound (echotexture and echogenicity) of the accessory sex glands. These exams will be repeated every two weeks for 90 days after castration. Blood samples will be collected in the same times of ultrasound exams for subsequent measurement of serum testosterone concentrations. The experimental design will be completely randomized with repeated installments on time. It will be the analysis of variance for repeated measures and Tukey test, using R © software 3.0.3. The level of significance will be 95% (p<0.05). | |
