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 [[Lizard and Snake Excretion|urination]]. The testicles increase in size during the breeding season.

A row of femoral pores can be seen on the medial aspect of the thigh in many families of lizard. The waxy secretion of cellular debris produced is thought by some to have territorial scent marking significance and by others to prevent the male sliding on the belly of the female during coitus (see also [[Preanal pore|preanal pore]]).
