Leopard Gecko Sex

We don’t always know the gender of our leopard gecko when we purchase one.  My first gecko I never actually found out she was a male or female until I took her into the pet store four years ago.  Not to mention naming them can come into factor when you are trying to determine their gender.  The chances are that if you have more than one leopard gecko, you’re going to want to house them together. Remember that two males can not be housed together, because they will fight and torment each other.  Females, on the other hand, can be housed together and generally will get along just fine.

Here is a picture which should help you in determining the gender of your leopard gecko:

It’s important to note that you will not be able to determine their gender until about the 3-4 month mark.  Sometimes it can take up to 6 months before they develop their male or female parts, though.

To figure out if Tony is “really” Tony, your going to have first to pick them up.  If your gecko is young, they might not be all that familiar with you yet.  That is fine, but make sure their body language isn’t trying to tell you to leave them alone.  The worst case scenario is that your leopard gecko will drop their tail because they are terrified of you.

So, once you have picked up your leopard gecko your going to want to turn them vertically and gently lift up their tail.

Male Gecko Traits:

  • Two hemipenal bulges that can be found at the base of their tails.  They should look like little lumps and should be pretty noticeable at the 3-4 month mark.
  • They will have a V-shaped vent between their hind legs.  These are called pre-anal pores (black).  These pores help them to scent their territory.  Therefore, males know when other males are in the same habitat.  There can be somewhat of a waxy build up around their pre-anal pores.
  • Have femoral pores on their hind legs.  They look like little bumps on their inner thigh.

Female Gecko Traits

  • Have femoral pores on their hind legs.  These are very tiny and shouldn’t be visible.
  • You won’t be able to see pre-anal pores.
  • They do have two hemipenal bulges at the base of their tail.

You should also keep in mind that males usually have larger heads than other females.  Their heads will be broader, and males typically weight a little more than females.  However, you should always pick them up and check their gender.  Hopefully, this article clears up some questions you might have about your leopard geckos gender.
