The clinical significance of sperm-zona pellucida binding.
The development of homologous functional bio-assay for sperm quality assessment has been a focal point of reproductive biologists; in order to provide a scientific based diagnosis in cases of fertilization failure. The availability of oocytes still remains an important limiting factor for laboratories to embark on the methodology of the assay. The use of zonae pellucidae, derived from post mort...
متن کاملRole of sialic acid in bovine sperm-zona pellucida binding.
Sperm binding activity has been detected in zona pellucida (ZP) glycoproteins and it is generally accepted that this activity resides in the carbohydrate moieties. In the present study we aim to identify some of the specific carbohydrate molecules involved in the bovine sperm-ZP interaction. We performed sperm binding competition assays, in vitro fecundation (IVF) in combination with different ...
متن کاملCellular mechanisms regulating sperm-zona pellucida interaction.
For mammalian spermatozoa to exhibit the ability to bind the zona pellucida (ZP) they must undergo three distinct phases of maturation, namely, spermatogenesis (testis), epididymal maturation (epididymis) and capacitation (female reproductive tract). An impressive array of spermatozoa surface remodeling events accompany these phases of maturation and appear critical for recognition and adhesion...
متن کاملA Role for Mouse Sperm Binding to Sperm Surface Galactosyltransferase the Egg Zona Pellucida in
Past studies have suggested that mouse sperm surface galactosyltransferase may participate during fertilization by binding N-acetylglucosamine (GIcNAc) residues in the zona pellucida. In this paper, we examined further the role of sperm surface galactosyltransferase in mouse fertilization. Two reagents that specifically perturb sperm surface galactosyltransferase activity both inhibit sperm-zon...
متن کاملA role for mouse sperm surface galactosyltransferase in sperm binding to the egg zona pellucida
Past studies have suggested that mouse sperm surface galactosyltransferase may participate during fertilization by binding N-acetylglucosamine (GlcNAc) residues in the zona pellucida. In this paper, we examined further the role of sperm surface galactosyltransferase in mouse fertilization. Two reagents that specifically perturb sperm surface galactosyltransferase activity both inhibit sperm-zon...
