title: Serum sperm antibodies unrelated to mumps orchitis.
abstract: In order to determine whether there is an association between mumps orchitis and serum sperm antibodies, we tested patients at the time orchitis was diagnosed (n = 7) and individuals who had had orchitis at least 1 month previously (n = 14). Data were compared with the results for a control group of blood donors (n = 20). Sperm antibodies were detected by the gelatin agglutination test of Kibrick, the tray agglutination test of Friberg and the ELISA. Clinically significant sperm antibody levels were not found in patients in the early stages of the disease. Four subjects tested post-disease were positive in the Friberg test and one was positive in the ELISA. One control serum was also positive in the latter test. Significant differences were not found between levels in patients in the early stages of the disease and levels in individuals post-disease, although the results of the Friberg test differed significantly between controls and former mumps orchitis cases. These data do not support the assumption of an involvement of humoral immunity against spermatozoa in mumps orchitis patients.
