{{further|Animal sexual behaviour#Lizards}}
Several species of [[Teiidae|whiptail lizard]] (especially in the genus ''[[Aspidoscelis]]'') consist only of females that have the ability to reproduce through [[parthenogenesis]].<ref>{{cite journal |last1=Cole |first1=Charles J.| last2 = Townsend | first2 = Carol R.| name-list-style = vanc |date=9 May 2005|title=Parthenogenetic lizards as vertebrate systems |journal=Journal of Experimental Zoology|volume=256 |issue=S4|pages=174–176 |doi=10.1002/jez.1402560436|pmid=1974787}}</ref> Females engage in sexual behavior to stimulate [[ovulation]], with their behavior following their hormonal cycles; during low levels of estrogen, these (female) lizards engage in "masculine" sexual roles. Those animals with currently high estrogen levels assume "feminine" sexual roles. Some parthenogenetic lizards that perform the courtship ritual have greater fertility than those kept in isolation due to an increase in hormones triggered by the sexual behaviors. So, even though [[asexual reproduction|asexual]] whiptail lizards populations lack males, [[sexual stimuli]] still increase reproductive success. From an [[evolutionary]] standpoint, these females are passing their full genetic code to all of their offspring (rather than the 50% of genes that would be passed in sexual reproduction). Certain species of [[gecko]] also reproduce by parthenogenesis.<ref>{{cite web|url=https://www.sciencedaily.com/releases/2005/06/050608053415.htm|title=Geckos: It's Not Always About Sex|last=Anon|date=9 June 2005|work=Science Daily|publisher=Lewis & Clark College |access-date=2008-12-14}}</ref>

Some species of sexually reproducing [[gecko]]s have also been found to display homosexual behavior, e.g. the day geckos [[Gold dust day gecko|''Phelsuma laticauda'']] and [[Blue-tailed day gecko|''Phelsuma cepediana'']].<ref>{{Cite journal|vauthors=Budzinski RM|date=1997|title=Homosexuelles Verhalten bei Geckos der Gattung Phelsuma.|url=http://www.sauria.de|journal=Sauria|volume=19|issue=3|pages=33–34|access-date=2020-07-25|archive-url=https://web.archive.org/web/20200607100011/https://sauria.de/|archive-date=2020-06-07|url-status=dead}}</ref>

====Tortoises====
[[Jonathan (tortoise)|Jonathan]], the world's oldest [[tortoise]] (an [[Aldabra giant tortoise]]), had been mating with another tortoise named Frederica since 1991. In 2017, it was discovered that Frederica was actually probably male all along, and was renamed Frederic.<ref name="thetimessthelenatortoise">{{cite news|last1=Binyon|first1=Michael| name-list-style = vanc |title=St Helena tortoise has a gay old time|url=https://www.thetimes.com/article/st-helena-tortoise-has-a-gay-old-time-6lcvnff7p|access-date=October 20, 2017|work=[[The Times]]|date=October 19, 2017}}</ref>
