Sperm Granuloma and Sperm Agglutination in a Dog with Asthenozoospermia.

Journal of Veterinary Medical Science, 2003
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 ...
