How to Sex a Leopard Gecko – 3 Easy Methods

The easiest and most reliable ways to sex leopard geckos is by looking for pre-anal and femoral pores. 

While Hemipenile bulges can also be used to identify a leopard geckos gender, this method is more challenging.

1.Pre-Anal Pores: The opening where leopard geckos excrete faecal matter is known as the vent. Just in front of the vent is where the pre-anal pores are located. In males, these round pores form a distinct V-shape. In female leopard geckos, these pores are barely noticeable. As a male leopard gecko matures, these pores will produce a waxy substance. Unlike in female leopard geckos, where no waxy substance will be produced.


2. Femoral Pores: These are located underneath your gecko’s hind legs. Just like the pre-anal pores, these are more prominent in males. They are a collection of white dots which appear in a straight line on each thigh. Female leopard geckos also have these pores, but they are much smaller and less distinct!


3. Hemipenile Bulges: In males, two distinct bulges behind the vent, near the base of the tail are present. These are the Hemipenile bulges and are where the male leopard gecko’s reproductive organs are found! If you’re interested in leopard gecko breeding, give Leopard Gecko Breeding – The Ultimate Guide a read! Some people will push the hemipenile bulges, causing the hemipenes (male reproductive organs) to pop out. I suggest you don’t do this as it can damage the hemipenes!
