Answer 2

You will have to wait until your gecko is at least 6 mos. old in order to be sure, as young male geckos look much like females until they mature. After about 6-7 months, however, you will notice a v-shaped line of pores that are very noticeable on the males, right in front of the vent (where your gecko goes to the bathroom).

Also, with males, you will see a more definate bulge in this area, as they have a hemipenis up inside their bodies.

Hope this helps!
