Sexing

Leopard geckos can be sexed after they have grown 5-6 inches long. The most reliable method of leopard gecko sexing is inspecting the areas before and after the vent.

  • Males have pre-anal pores, which looks like a small line of dots across the underside of the back legs in front of the vent. They also have two oval bulges behind the vent – these indicate hemipenes.
  • Females do not have pores or hemipenal bulges.

Males and females should not be housed together unless you intend to breed them. Even then, the arrangement should be temporary only.
