title: B-mode ultrasonography of the bull testicle.
abstract: The scrotum and testicles from 20 bulls aged 6 mo to 10 yr were obtained from a slaughterhouse and ultrasonically scanned to determine the normal echographic anatomy Ultrasonically, the normal bull testicle was homogeneous and moderately echogenic. The mediastinum testis was a linear structure in the center of the testicle and was slightly more echogenic than the parenchyma. The head and tail of the epididymis were easily identified on all testicles, but the epididymal body and ductus deferens were difficult to identify consistently. Ultrasound scanning of the testicles may prove to be a valuable noninvasive diagnostic technique for evaluating testicular diseases in bulls.
