Whether antisperm antibodies develop after vasectomy probably depends on several variables, 1 of which may be the surgical technique. The levels of serum antisperm antibodies were compared in men vasectomized by 2 techniques: vasoligation and fulguration. No difference in the incidence of spermagglutinating antibody was found in the 2 groups. However, immobilizing antibodies were observed in 43 percent of the men undergoing vasoligation but in only 29 percent of the men vasectomized by fulguration.
