Male vs Female Leopard Gecko

The difference between male and female leopard geckos is easy to spot once you know when and what to look for. 

If you haven’t been provided with the sex of your Leo by your breeder, then this article is for you. I will provide all the necessary knowledge you’ll need to do this yourself safely.

Easiest Way To Find Out?

You’re able to find out the sex of your Leopard Gecko immediately as long as your breeder knows the incubation temperature. If this information isn’t available to you here’s everything you need to know to be able to identify the gender yourself.

Pro Tip: Ensure your Leopard Gecko is at least 6 months in age because you’re unable to identify gender before this time.

How To Handle For Sexing

Sexing Leopard Geckos requires handling, so If you’re inexperienced with handling Leopard Geckos, it is important to learn before investigating the sex. If you are experienced, skip to the next section of this article.

Before starting, ensure your hands are clean.

The key to this is to be gentle and patient. Always pick your Leo up from the base of their body and ensure you do not grab the tail. If your Leo is showing stress or discomfort by animated movements then place them back in their tank and try again another time. 

Scaring a Leopard Gecko can cause them to drop its tail, this is something they do as a defense tactic from predators. You want to avoid this happening as best you can. If this does happen, don’t panic it’s completely natural and it does regenerate.

Once you’ve managed to get your Leo comfortable with being held, lift them above your head to inspect their base instead of turning them upside down. If this is something you find awkward to do, you can place them in a transparent container and view them through this. 

How To Tell The Difference?

Now you know how to handle a gecko, let’s discuss what differences to look for in males and females.

Preanal Pores

Females do not have preanal pores at all. 

The males have Preanal pores located on the base in between their legs and form a V shape. These pores are pronounced and look like black/brown spotting.

Hemipenal Bulges

The Hemipenal bulge is only found in males, this is what houses their reproductive organs. These are located below the base of the tail on either side of the vent.

During mating, these bulges will be enlarged temporarily.

Femoral Pores

These pores can be found on the thighs of the hind legs and look like tiny white spots. Both males and females have them, however, they’re more visually prominent in males.

These femoral pores are used by males to excrete pheromones to attract potential mates and mark territory. 

Full Maturity Sizing

Male and Female Leopard Geckos are sexually dimorphic

A male typically will reach a size of 8”-11” and a weight of 40-80 grams. Whereas a female typically only reaches 7”-7.9” and a weight of 50-70 grams.

How Incubation Influences Gender

The sex of your Leopard Gecko can be determined by the temperature they were incubated. Depending on the temperature, you’re able to have a clutch of mixed, male, or female Leopard Geckos.

79°F-81°F for 21 days – Then increase to 88°F-90°FFemale

Can You House Males and Females Together?

No, is the short answer. Leopard Geckos are territorial and solitary reptiles. Housing them together can result in fighting and injury. In extreme cases, fatalities can occur. I only recommend putting males and females together during breeding months to avoid this.


If your breeder is unable to provide you with the information you require about your Leopard Geckos’ sex and you want to find out for yourself remember;

  • Can investigate sex are 6 months of age
  • Check for preanal pores
  • Check for Hemipenal bulges
  • Check for Femoral pores

Taking what you have learnt in this article, will help you be able to identify the sex of your Leopard Gecko safely.
