spermatozoa

Spermatozoa, commonly known as sperm, are the male reproductive cells responsible for fertilizing the female egg in sexual reproduction. Each sperm cell is made up of a head, which contains genetic material, and a tail, which propels it forward. Sperm are produced in the male reproductive system, specifically in the testes, through a process called spermatogenesis. During ejaculation, millions of sperm are released, aiming to reach and fertilize an egg, leading to the formation of an embryo. Their health and quality are crucial for successful reproduction.
