Many studies of the molecular and biochemical aspects of mammalian fertilization have
focused on the interaction of the spermatozoa with the zona pellucida (ZP). The zona …

Recognition between mammalian gametes occurs when the plasma membrane of the sperm
head binds to the zona pellucida (ZP), an extracellular coat surrounding eggs. ZP3, one of …

Sperm-induced activation of mammalian eggs is associated with a transient increase in the
concentration of intracellular Ca2+. The role of inositol 1, 4, 5-trisphosphate (IP3) mediated …

It is known that only acrosome-reacted spermatozoa can fuse with the oolemma during
normal fertilization with zona pellucida-intact oocytes. The aim of this study was to determine …

Complementary adhesion molecules are located on the surface of mouse eggs and sperm.
These molecules support species-specific interactions between sperm and eggs that lead to …

During spawning, female Sicyonia ingentis simultaneously release ova and stored
nonmotile sperm and mix them externally to initiate gamete interaction. Sperm bind to a thin …

Objective To determine whether the sperm-zona pellucida (ZP) binding is related to the
presence of immunoreactivity for proacrosin and acrosin and/or to the proteolytic activity of …

The non-enzymatic isolation procedure of zona pellucida from the ovaries of domestic cats,
presented here, can provide a sufficient number of oocytes (163±73 per ovary) for further …

Comprehension of the intricate complexities of sperm function is clearly crucial to the
success of attempts to manipulate it for the purposes of assisted conception. This is …

Intercellular communication between gametes is essential to the unique event in the life
cycle of an organism called fertilization. Achievement of successful fertilization results from …
