Immunocytochemical characterization of round cells in human semen using monoclonal antibodies and the APAAP-technique.

Round cells of 42 ejaculates were characterized by their surface antigens using monoclonal antibodies and the immunocytochemical APAAP-technique. In this way immature germ cells, polymorphonuclear leukocytes, lymphocytes and their subpopulations could be distinguished. It was also attempted to correlate the incidence of these cells, sperm parameters and other clinical data.
