Wondering whether your bearded dragon is a boy or a girl? The answer is usually easy to spot once you know what to look for — though it’s much harder in young dragons.
This guide explains how to tell if a bearded dragon is male or female, and when the differences become clear.
1. Check for Hemipenal Bulges (Most Reliable)
The most reliable sign is under the tail, near the vent (cloaca):
- Male: two distinct bulges (hemipenes) run along the base of the tail, one on each side of the midline.
- Female: a single, smaller central bulge — or no obvious bulge at all.
How to check safely:
- Hold your dragon gently and support its body.
- Lift the tail slightly (never force it — you can injure the spine).
- Look at the underside of the tail base, just below the vent.
2. Look at the Femoral Pores
Along the underside of the thighs are rows of small dots called femoral pores:
- Male: pores are larger, darker, and more prominent (they secrete a waxy substance).
- Female: pores are smaller and less noticeable.
3. Compare Head and Body Shape
- Males typically have broader, blockier heads and larger bodies.
- Females are usually slightly smaller with narrower heads.
This is the least reliable method on its own — size and head shape vary a lot between individuals.
When Can You Tell?
- Babies (under ~4 months): very hard to sex reliably — the bulges haven’t developed yet.
- Juveniles (6+ months): differences start to become clear.
- Adults (12+ months): usually obvious, especially the hemipenal bulges.
The Most Accurate Method
For 100% certainty, a reptile vet or experienced breeder can perform “sexing” by gently everting the hemipenes or using a light (“transillumination”) through the tail base. Never try to force the hemipenes out yourself — this can cause serious injury.
Bottom line: in an adult, the two hemipenal bulges under the tail are the clearest sign of a male. When in doubt, ask a vet or breeder.
