How do you tell the difference between male and female lizards?

Answer by  SallyManda (308)

Some lizards differ in coloration or size, particularly during the breeding times. However, its often very difficult to tell. X-rays and internal probes can be used. If they are bred in captivity, the sex of the animal can be determined based on the temperature of egg incubation.

It is quite difficult and sometimes impossible to do so without the help of an expert. However, if your lizard will allow it there is a way. You will want to gently press the space between tail and tummy. If you feel a poke it is male.

Sexing lizards varies from species to species. It can be anything from significant sexual dimorphism, with males or females being larger, to having a couple bulges near their anal vent.

That depends greatly depending on the species. With some species it's really easy to tell based on color or size. Many male gecko species develop a distinct and noticeable "hemipenal bulge" at the base of their tail that is a dead giveaway. With other species of lizards there are absolutely no outward indicators of sex.

Honestly, to tell the difference between male and female lizards depends on the species. For the Family Iguanidae, males have larger heads and more pronounced dewlaps than females.

It's not easy to tell the difference since lizards don't have external sex organs. An experienced lizard owner can tell the difference by looking at the vent of the aniamal.
