Sexing Your Leopard Gecko-Pink or Blue ??

In the leopard gecko world gender neutrality isn't really encouraged :))
If you put two females together and/or two males together serious fighting and injury can occur. Or on the flip side, if you put a male and a female together you may become a grandparent to a lot of baby geckos. None of which you were prepared for. So, how do you "sex" a gecko--

Sexing reptiles can be tricky, but it's not as hard in leopard geckos as it is in others, as long as you're dealing with adults and know what to look for.  In general, female geckos will be smaller and more lightly built than males, with duller colors.  However, this is not always the case. 

Male geckos have pre-anal pores in a V-shaped arrangement in front of the cloacal opening.  Females have these, too, but they are less prominent and lighter in color than those of a male, and will be harder to see.  The hemipenes in males make a noticeable bulge at the base of the tail, as well. 

Expect your lizards to be sexually mature and for these features to be identifiable between twelve and fifteen months of age.  Before this time, sexing may be more complicated and difficult.
