The purpose of this study was to observe changes in the testicular parenchyma of male goats. Changes were observed in terms of goat age, evaluating the echotexture and ultrasound viability in the testicles. Four animals were used, ranging from six to 13 months of age. The echographic examinations were performed every 15 days to assess echotexture of the testicle. The testicular parenchyma appeared moderately echogenic and homogeneous. Similar results were observed in testicular echotexture during the evaluation period. The highest results appearing during the eighth month of age, when the testicular volume was also highest; such changes were related to the regional photoperiod. The ultrasound evaluation of the testicles was shown to be an effective method, ultimately capable of detecting changes in testicular parenchyma over time, being an alternative to differentiation normal and pathological conditions in goats.
