Polyspermy is a condition where an egg is fertilized by multiple sperm cells, leading to an abnormal number of chromosomes and typically resulting in embryo inviability. To prevent polyspermy, organisms employ mechanisms such as the fast block, which involves a rapid change in the egg's membrane potential to deter additional sperm from entering, and the slow block, which involves the release of enzymes that harden the egg's outer layer, creating a physical barrier. These mechanisms ensure that only one sperm successfully fertilizes the egg, maintaining proper genetic balance.
