Instructions
Hold your house gecko in your hand, so that its belly is facing you. The head should be upright and the tail should be pointing toward the floor.
Identify the vent area on your house gecko. The vent is where the gecko eliminates its waste, and it is located near where the tail meets the body.
Look for the presence of a bulge under the vent area, toward the tail. If you detect a bulge, the gecko is likely male, according to GeckosForPets.com. This bulge is where the hemipenes is located. Females do not have bulges in this area.
Look above the tail for a dark line of pores. Males typically have a dark, V-shaped line above the tail, known as the femoral pores. Females also might have the same line, but it is not as prominent or dark as it is in males.
