Plain-English summary
A 2-year-old mongrel dog was brought in due to fertility issues, showing very few sperm that were not moving and clumping together in his ejaculates. A small nodule was found in his scrotum, which turned out to be a sperm granuloma (a lump caused by sperm leakage). Tests suggested that the dog's own semen contained antibodies that were affecting sperm movement and causing the clumping. Unfortunately, this condition indicates a significant fertility problem, and the dog may need specialized treatment to address the underlying issues.

Abstract
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.
