How Do Reptiles Fertilize Eggs
Most lizards reproduce sexually, meaning they need a male and female to mate, fertilizing an egg. Some lay eggs and other give birth to live young, with the egg developing inside the mother. Reproduction is very much dependent on the type of species and their location in the wild.

How long are reptiles pregnant?

On average, temperate-zone reptiles have incubations or pregnancies of 8–12 weeks. Tropical species tend to have similar incubation periods; however, incubations of some species may last nearly one year or longer (as in the Fijian iguana [Brachylophus fasciatus]).

Why do some reptiles lay eggs?

Though often associated with birds, eggs with shells were “invented” by reptiles. The evolutionary adaptation allows reptile eggs to be laid on land and gives them some degree of protection from the environment and potential predators at the same time – traits that shell-lacking amphibian eggs lack.
