The cortical reaction is a process initiated during fertilization by the release of cortical granules from the egg which prevents polyspermy, the fusion of multiple sperm with one egg.
Successful fertilization requires not only that a sperm and egg fuse, but that not more than one sperm fuses with the egg. Fertilization by more than one sperm-polyspermy-almost inevitably leads to early embryonic death.At the end of the chain are links that have evolved to efficiently prevent polyspermy.he cortical reaction refers to a massive exocytosis of cortical granules seen shortly after sperm-oocyte fusion. Cortical granules contain a mixture of enzymes, including several proteases, which diffuse into the zona pellucida following exocytosis from the egg.
