Sexing

Sexing gargoyle geckos is a fairly straightforward process. Males have a prominent bulge at the base of the tail which contains hemipenes (male sex organs); female’s don’t. If male, this bulge develops between 18-25g.

Some breeders claim to be able to determine the sex earlier by examining for femoral pores with a magnifying glass or a jeweler’s loupe, but this isn’t always accurate, so sex cannot be truly confirmed until hemipenes develop (or don’t).
