Characterization of Antibodies Generated Against a Conserved Portion of Oviductal Glycoprotein (OGP) and Endogenous Hamster OGP and Their Ability to Decrease Sperm Binding to the Zona Pellucida In Vitro

Abstract

These results suggest that OGP may be a potential immunocontraceptive target because both antibodies significantly decreased sperm binding to the ZP of oviductal oocytes. Immunocontraception may be accomplished by attempting to generate active immunity to a recombinant OGP, to the region selected in this study (amino acids 52-68) or to some other region of the core protein.
