Birds and reptiles evolved to lay shelled eggs that required fertilization to happen before the protective shell is formed. Internal Fertilization is one way to make this possible. Sperm, the male gamete, is a single cell with a flagellum that allows it to move or "swim" in fluids. Internal fertilization creates a contained environment in which the sperm can "swim" to the ovum, the female gamete.
