Regulation of Mammalian Fertilization by Gamete Adhesion Molecules, our attempts to identify and characterize those molecules associated with the surface of mouse eggs and sperm that regulate species-specific gamete adhesion before and after fusion of gametes. We have made considerable headway with the egg surface (zona pellucida) components and, consequently, this

Increasing evidence points out that sperm-egg recognitions and binding actually involve carbohydrate-protein interaction (Ahuja 1982; Huang et al. 1982; Macek and Shur 1988; Jones and Willi

Regulation of Mammalian Fertilization by Gamete Adhesion Molecules, aspect constitutes the bulk of the presentation. However, some attention is paid to sperm surface components involved in adhesion of sperm to eggs. It should be noted that there is evidence to suggest that conclusions drawn from our research on mice apply as well to many other mammals, including human beings.
