title: [Expression of leukocyte antigens in human sperm].
abstract: The expression of leukocyte antigens on human ejaculated spermatozoa and lymphocytes was compared by means of the immunofluorescence technique and monoclonal antibodies against anti-HLA class I (pan-HLA-A,B,C) and class II (DR, DR/DP). Lymphocytes showed specific fluorescence phenomena after incubation with the antibodies. However, in the case of spermatozoa no immunofluorescent labeling was detected. Modifications of the method of sperm preparation (Ficoll centrifugation, swim-up technique, addition of azide, fetal calf serum or benzamidinchloride) did not lead to different results. We were not able to find HLA-antigen expression on fresh human spermatozoa using immunofluorescence.
