sperm cell

A sperm cell is a microscopic reproductive cell produced by males. It has a head containing genetic material (DNA) that combines with a female's egg during fertilization. The head is topped with a tail-like structure called a flagellum, which enables it to swim toward the egg. Sperm cells are designed for mobility and to carry genetic information essential for creating a new human life. They are produced in the testes and are a crucial part of human reproduction.
