A mongrel dog, aged 2 years, was found to have only a small number of sperm, immobilization of all sperm, and many sperm agglutinations in its ejaculates, and scrotal palpation revealed a small nodule in the left cauda epididymis. Addition of the dog's seminal plasma or serum to the semen of 2 normal dogs caused immobilization and agglutination of their sperm. Histological examination showed that the nodule was a sperm granuloma. Many lymphocytes were seen in the stroma around the sperm granuloma. Anti-sperm antibodies are presumed to be present in the semen and serum of the asthenozoospermic dog.
一只2岁的杂种狗被发现其射精中只有少量精子、所有精子均不活动且有许多精子凝集现象，阴囊触诊发现左侧附睾尾部有一个小结节。将该犬的精浆或血清加入2只正常犬的精液中，导致其精子不活动和凝集。组织学检查显示该结节为精子肉芽肿。在精子肉芽肿周围的间质中可见许多淋巴细胞。推测弱精子症犬的精液和血清中存在抗精子抗体。
