[Vasectomy and spermatic antibodies].

Before vasectomy, 4 weeks and 3 months after the intervention the sera of 56 fertile patients were examined for the existence of sperm-agglutinating and sperm-immobilizing antibodies. Before vasectomy no antibodies with a titre of 1 : 16 could be established. 4 weeks after vasectomy in 9 sera sperm-agglutinating and in 4 sera sperm-immobilizing antibodies with a titre of 1 : 32 or more could be proved. There was a clear connection with inflammable changes at the place of the peripheral ligature (sperm granulomas). After 3 months with the exception of 2 sera the antibodies had decreased to a titre of less than 1 : 16 or they had disappeared.
