What causes the slow block to polyspermy?

The slow block to polyspermy is caused by changes in the egg's membrane potential and increased intracellular calcium levels, which prevent additional sperm from fertilizing the egg. This physiological response allows only one sperm to successfully fertilize the egg and prevents the formation of abnormal embryos with multiple paternal contributions.
