Like most vertebrates, birds have two forms of gonadotropin-releasing hormone (GnRH). Chicken GnRH-I (cGnRH-I) is released at the median eminence to elicit gonadotropin release; chicken GnRH-II (cGnRH-II) is thought to be non-hypophysiotropic and its function is unclear. Both forms are hypothesized to act as neurotransmitters in the control of reproductive behavior. In the present study, we implanted chronic cannulae aimed at the third ventricle in female white-crowned sparrows (Zonotrichia… 
Effects of Gonadotropin-Releasing Hormones, Corticotropin-Releasing Hormone, and Vasopressin on Female Sexual Behavior
TLDR
The data indicate that neurohormones of the hypothalamic-pituitary-gonadal and the leptin-releasing hormone axes can facilitate reproductive behavior in S. murinus.
Actions of two forms of gonadotropin releasing hormone and a GnRH antagonist on spawning behavior of the goldfish Carassius auratus.

TLDR
The results indicate that GnRH peptides play a major role in the control of female reproductive behavior in goldfish, but have little or no role inThe control of male behavior.
Sex differences in mammalian and chicken-II gonadotropin-releasing hormone immunoreactivity in musk shrew brain.
TLDR
Data suggest that the phylogenetically conserved cGnRH-II form is regulated by ovarian hormones and, thus, may be involved in the brain-pituitary-gonadal feedback axis.
Gonadotropin-releasing hormone II stimulates female sexual behavior in marmoset monkeys.
TLDR
Findings implicate a role for GnRH II and the cognate GnRH type II receptor in stimulating female marmoset sexual behavior and alter the frequency of proceptive behaviors.
An evolutionarily conserved form of gonadotropin-releasing hormone coordinates energy and reproductive behavior.
TLDR
It is demonstrated that in a primitive mammal, the musk shrew (Suncus murinus), GnRH-II activates mating behavior in nutritionally challenged females within a few minutes after administration, leading to hypothesize that the role of the evolutionarily conserved Gn RH-II peptide is to coordinate reproductive behavior as appropriate to the organism's energetic condition.
The control of reproductive physiology and behavior by gonadotropin-inhibitory hormone
TLDR
The existing data suggest that GnIH/RFRP is an important mediator of reproductive function acting at the level of the brain, pituitary, and the gonad in birds and mammals and may serve as a transducer of environmental information and social interactions into endogenous physiology and behavior of the animal.
Gonadotropin Inhibitory Hormone Down-Regulates the Brain-Pituitary Reproductive Axis of Male European Sea Bass (Dicentrarchus labrax)1
TLDR
This work represents the first study reporting the effects of centrally administered GnIH in fish and provides evidence of the differential actions of sbGnIH-1 and sb gnIh-2 on the reproductive axis of sea bass, the main inhibitory role being exerted by the sb GnI H-2 peptide.
RNA Interference of Gonadotropin-Inhibitory Hormone Gene Induces Arousal in Songbirds
TLDR
Gonadotropin-inhibitory hormone may decrease arousal level resulting in the inhibition of specific motivated behavior such as in reproductive contexts, and RNA interference of the GnIH gene silencing induces arousal.

Identification of the second gonadotropin-releasing hormone in chicken hypothalamus: evidence that gonadotropin secretion is probably controlled by two distinct gonadotropin-releasing hormones in avian species.
TLDR
The results indicate that gonadotropin secretion is probably controlled by two distinct GnRHs, at least in avian species.

TLDR
Treated ring doves treated with synthetic LH releasing hormone enabled such birds to show typical female behaviour, thus supporting the hypothesis that a high dose of oestrogen suppresses the synergistic action of GnRH with oestrogens which is required to elicit courtship behaviour.
Modulation of the lordosis reflex of female rats by LHRH, its antiserum and analogs in the mesencephalic central gray.
TLDR
Effects of intracerebral infusion of LHRH and related compounds on the lordosis reflex were examined in ovariectomized, estrogen-treated female rats and showed a clear dissociation between their behavioral effects and their reported effects on LH release.
Immunohistochemical localization of chicken gonadotropin‐releasing hormones I and II (cGnRH I and II) in turkey hen brain
TLDR
The distribution of cells and fibers immunoreactive for either chicken gonadotropin‐releasing hormone I or II was determined in brains of turkey hens to reveal whether these peptides occur in separate neuronal systems and that cGnRH II does not directly promote pituitary gonadotropic hormone secretion.
