Histopathology of male cattle previously found positive for béta-boldenone in urine in the Netherlands and in Italy was studied. The animals were derived from practice and several weeks had passed after the finding of béta-boldenone before the animals were examined. The animals consisted of 34 male veal calves and one finishing bull. In the prostate gland hypersecretion, cyst formation (45%) and hyperplasia of the urethral epithelium was observed, in the bulbo-urethral gland similar alterations were present. The testis showed reduced development and degeneration of the germinal epithelium (70%) leading to debris and syncytial cell formation in the lumina. Stromal proliferation was evident. In some animals the liver was sampled and showed periportal fibrosis, bile duct proliferation and sometimes necrosis. The bull also showed degeneration of the germinal epithelium of the testis and absence of sperm production, the prostate gland showed some secretion and had an atrophic appearance. It is concluded that béta-boldenone may lead to degeneration of the germinal epithelium of the testis and hypersecretion and cyst formation in the prostate and bulbo-urethral gland, which alterations may heal in time.
