[Autoantibody formation following voluntary vasectomy (author's transl)].

Serum autoantibodies were determined in 33 of 60 patients 3 to 24 months following a voluntary vasectomy. The macroscopic spermagglutination test according to the method of Kibrick and the immobilization test according the method of Isojima were used. Agglutination antibodies (titer greater than or equal to 1:2) were found in 55% of the patients with a maximal titer of 1:128. Titers from 1:32 were found in 6% of the cases. Immobilization antibodies (titer greater than or equal to 1:2) were found in 24% of the cases with titer values up to 1:16. There is no correlation between the antibody titers and the time of the vasectomy. There were no clinical indications of autoimmunological disease.
