There are a few different ways documented of sexing Bearded Dragons, though
only one that has proven to be most effective. The most effective way is to
attempt to view the hemipenal bulges and the lack there of in females. Sexing
hatchling Bearded Dragons can be tricky as they are so small and the hemipenes
are harder to expose. With a Bearded Dragon that is 4 or more weeks old the
process is much easier.
To safely and effectively expose the hemipenal bulges, place the specimen
Bearded Dragon in the palm of your hand or on a sturdy surface where the body
and legs of the Bearded Dragon will be supported and with the tail facing you
and gently bend the tail straight up and look just above the ventral opening.
In male Bearded Dragons you will be able to see the hemipenal bulges on both
sides of the base of the tail, which will cause and indentation between the
two hemipenes, where as in females the hemipenal bulges will not be present.
Due to the lack of hemipenal bulges in female Bearded Dragons you will notice
a single bulge centered just above the ventral opening.
Notice the two hemipenal bulges and the centered indentation in Males (left)
and the lack of them Females displaying only the single centered bulge
(right).
Another way to sex your Bearded Dragon, though really only works well on adult
Bearded Dragons is checking for femoral pores along the insides of the rear
legs. Both sexes have them but as adults the males femoral pores will be
enlarged and a lot easier to see whereas in females they stay relatively small
and harder to see.

and the smaller less visible femoral pores in Females (right).
