What is the function of the cortical reaction?

The cortical reaction is a process that occurs in fertilization where the released enzymes and calcium ions cause changes in the egg's zona pellucida to prevent polyspermy, the entry of multiple sperm into the egg. This helps ensure that only one sperm fertilizes the egg, which is essential for successful development.
