Role of Gonadotropin-Releasing Hormone in Regulation of Gonadotropin Secretion from Amphibian and Reptilian Pituitaries

  • Chapter
Hormones and Reproduction in Fishes, Amphibians, and Reptiles

Abstract

The ubiquity of a brain peptide involved in regulating pituitary gonadotropin (Gn) secretion in vertebrates has been confirmed by a variety of direct and indirect studies.57 This gonadotropin-releasing hormone (GnRH) [also known as luteinizing hormone-releasing hormone (LHRH)] has been extensively characterized biochemically and physiologically in mammals, but data for nonmammalian species are still very limited. Indeed, our use of the term GnRH, unless specified otherwise, will refer to the mammalian decapeptide:

$$ {\rm{pGl}}{{\rm{u}}^1} - {\rm{Hi}}{{\rm{s}}^{\rm{2}}} - {\rm{Tr}}{{\rm{p}}^{\rm{3}}} - {\rm{Se}}{{\rm{r}}^4} - {\rm{Ty}}{{\rm{r}}^5} - {\rm{Gl}}{{\rm{y}}^{\rm{6}}} - {\rm{Le}}{{\rm{u}}^{\rm{7}}} - {\rm{Ar}}{{\rm{g}}^{\rm{8}}} - \Pr {{\rm{o}}^{\rm{9}}} - {\rm{Gl}}{{\rm{y}}^{{\rm{10}}}} - {\rm{N}}{{\rm{H}}_2}. $$
