Male lizards have paired hemipenes that are sac-like and lack erectile tissue. They are stored, inverted, in the base of the tail and may produce bulges in the ventral proximal tail. Only one is used at a time during copulation and it is not involved in urination. The testicles increase in size during the breeding season.
