Lizard reproductive strategies vary; they may be:

* oviparous - laying eggs (most lizards)

* '''oviparous''' - laying eggs (most lizards)

* ovoviviparous - the eggs are retained within the female until birth of live young (all monitors, most iguanids, water dragons, all geckos, most chameleons)

* '''ovoviviparous''' - the eggs are retained within the female until birth of live young (all monitors, most iguanids, water dragons, all geckos, most chameleons)

* viviparous - live-bearing, with a placental type of circulatory connection (blue-tongued skinks, shingle-backed skink, prehensile-tailed skink, Jackson's chameleon)

* '''viviparous''' - live-bearing, with a placental type of circulatory connection (blue-tongued skinks, shingle-backed skink, prehensile-tailed skink, Jackson's chameleon)

* parthenogenic - asexual reproduction found in lizards such as certain ''Lacerta'' spp. and whiptail lizards (Aspidocelis [''Cnemidophorus''] spp.) consisting entirely of females. Although they reproduce asexually, these females still show courting and pseudocopulation.

Parthenogenesis has been reported in about 30 species of lizards.
