Lizards reproduce in different ways. While most lizards reproduce by laying eggs after a female is inseminated by a male, other types of lizards reproduce asexually, meaning they do not need a mate in order to produce offspring.
During mating season, the glands at the base of the tail of males and females produces a smell that attracts the opposite sex. Females are attracted to the males who have the strongest odors. Males and females do not remain together after mating. Males continue to look for new females with whom they can mate, while females look for ways to make sure they will be able to safely produce their young. A female lizard will begin looking for locations where predators are unlikely to find the eggs after she lays them. The female lizard lays the eggs but does not wait for them to hatch. Approximately three months after the mother leaves, the eggs will hatch. Although there are some types of lizards that lay only one egg, most lay several eggs at once.
Some species of lizards give birth to live young rather than laying eggs. Other species do not need a male to reproduce, but those species are very rare. Only a few types of lizards are able to reproduce asexually, including some species of whiptail lizards.
