Identification of Human Sperm Antigen Recognized by Serum of an Immunoinfertile Woman: A Candidate for Immunocontraception

Abstract

This study has put in evidence an antigen of apparent molecular weight of 71-kDa in all donor sperm tested in this study. The presence of this antigen on the sperm of several species will enable us to determine the efficacy of this antigen in controlling fertility in vivo in both rodents and primates. This antigen may be a candidate for immunocontraception.
