How old is your leo?
Sexing Leopard Geckos -- A leopard gecko's gender can be confirmed when that leo is
over 5 inches in total length. That may happen when the leo is near 6 months old. Males can be distinguished from females by a
distinct /\-shaped row of pores above the vent and by two hemipenal bulges below the vent. To see their vents, potential male pores, and hemipenal bulges
gently press their bodies up against the glass. They'll squirm if you try to turn them over.
