This study aimed to describe ultrasonographic findings in the testis and epididymis of young sheep. Evaluations of the development of weight, measurements of biometric characteristics of the tests and ultrasound examinations of the tests and epididymis were performed from 140 to 280 days of age, each 28 days. The testicular parenchyma showed homogeneous echogenicity (low to moderate) and increased with the age. The mediastinum echogenicity and thickness increased with age and the epididymis tail showed hypoechoic appearance in relation to the testicular parenchyma. Mild calcification was observed in the testis parenchyma of five lambs. In conclusion, ultrasonographic exams help to monitor testes and epididymis of young hair rams.
