title: Absence of circulating HL-A lymphocytotoxic antibodies in men 21 to 44 months after vasectomy.
abstract: Nineteen vasectomized men were followed for 21 to 42 months after surgery, and their sera were tested for the presence of HL-A lymphocytoxic antibodies. In a previous study, the sera of two of these men had shown a definite increase in serum reactivity 6 to 12 months after surgery. Only one of the nineteen tested in the study demonstrated, a single, weakly positive, reaction 24 months after surgery. It was considered that the initial stimulus for lymphocytotoxic antibody production was related to surgery. There was no evidence of antibody stimulation 21 to 44 months postoperatively.
