Male lizards have two reproductive organs, called hemipenes. Only one at a time is used during mating. The male simply mounts the female, often grabbing her by the neck or side, and inserts one into her cloaca, then they remained locked together for a while. It is a much less active affair than what is seen in mammals or birds.
Some species lay leathery or hard-shelled eggs, while others give live birth.
