Lack of association of the development of anti-sperm antibodies and other autoantibodies as a consequence of vasectomy.
The possibility of autoantibodies--other than sperm antibodies--developing as a consequence of vasectomy has been investigated in 255 volunteers. During the first year after vasectomy no obvious increase was observed in the occurrence of any of these antibodies (rheumatoid factor, antinuclear antibodies and antibodies against smooth muscle, mitochondria, gastric parietal cell, thyroid microsomes and thyroglobulin). Ninety-nine of the patients were also examined for agglutinating and immunofluorescent antibodies to sperm to see if there was any relationship between the occurrence of anti-sperm antibodies and other autoantibodies. However, the prevalence of non-sperm autoantibodies did not differ in two nearly equal groups of patients with and without indications of autoimmune reactions to spermatozoa, respectively. Consequently the present results lend no support to the hypothesis that vasectomy could induce autoimmunity to other autoantigens than sperm-specific antigens.
