By: J. Godwin*, V. Hartman*, M. Grammer* & D. Crews*

MeSH headings : Animals; Biological Evolution; Down-Regulation / drug effects; Estradiol / physiology; Female; Gene Expression / drug effects; Guinea Pigs; Lizards / genetics; Lizards / physiology; Parthenogenesis / drug effects; Progesterone / physiology; RNA, Messenger / genetics; Rats; Receptors, Estrogen / genetics; Receptors, Progesterone / genetics; Sexual Behavior, Animal / physiology; Species Specificity; Ventromedial Hypothalamic Nucleus / physiology
TL;DR: The correlated decrease in both EB-induced receptive behavior and ER- and PR-mRNAs following progesterone administration are similar to findings in rats and guinea pigs, suggesting that this is an evolutionarily conserved mechanism in the regulation of female sexual behavior.

MeSH headings : Animals; Behavior, Animal; Brain / drug effects; Female; In Situ Hybridization; Lizards; Male; RNA, Messenger / biosynthesis; Receptors, Estrogen / physiology; Receptors, Progesterone / physiology; Sex Characteristics; Sex Factors; Sexual Behavior, Animal
TL;DR: Sex differences in the regulation of steroid hormone receptors in brain areas controlling female- and male-typical sexual behavior may be important in determining sex Differences in the display of these behaviors. (via Semantic Scholar)

Behavioural aspects of protandrous sex change in the anemonefish, Amphiprion melanopus, and endocrine correlates

Animal Behaviour, 48(3), 551–567.

By: J. Godwin*

TL;DR: Overall aggression increased and the ratio of attacks at the periphery of the territory to those at the centre increased with time after female removal, and there was no convincing evidence of a relationship between plasma levels of the five steroids measured and male/female behavioural differences or (2) behavioural changes with sex change.

Journal of Zoology, 232(2), 199–213.

By: J. Godwin*

TL;DR: Gonadal structure and cellular composition were examined in juveniles, males and females of the protandric hermaphrodite, Amphiprion melanopus and significant variation between individuals was seen in quantitative measures of gonadal change in the early stages of sex change, but not in later stages.

Sex Change and Steroid Profiles in the Protandrous Anemonefish Amphiprion melanopus (Pomacentridae, Teleostei)

General and Comparative Endocrinology, 91(2), 144–157.

TL;DR: The results support hypothesized roles for androgens in male function and E2 in female function in A. melanopus, however, E2 increases lagged behind oogonial proliferation, arguing against an influence of this steroid in the initiation of female function. (via Semantic Scholar)
