A sperm cell is a specialized reproductive cell found in the male reproductive system of humans. It is responsible for fertilizing the female egg during sexual reproduction, leading to the formation of a new human life. Sperm cells are characterized by their small size, streamlined shape, and long tail, which enables them to swim toward the egg. They carry genetic information from the male parent and play a crucial role in the process of human reproduction.
