👉 The sperm weapon, also known as the acrosome reaction, is a specialized mechanism used by certain male sperm cells to enhance their ability to fertilize an egg. When a sperm encounters the egg's outer layer, the acrosome—a cap-like structure rich in enzymes—releases these enzymes to break down the protective layers, allowing the sperm to penetrate the egg's outer shell and reach the egg's nucleus for successful fertilization. This process is critical for male fertility, as it ensures that sperm can effectively navigate and fertilize the egg despite its physical barriers.
