This review summarises research over the last 10 years regarding sex steroids (17β-estradiol, testosterone, 11 ketotestosterone and 17α, 20β-DHP), gonadotropins (Fsh and Lh), their main regulators (GnRH1-3 and GnIH1-3) and their functions in modulating reproduction. It focuses specifically on the hypothalamic–pituitary–gonadal (HPG) axis in model and Neotropical teleosts (Astyanax altiparanae, Steindachneridion parahybae, Salminus hillarii and Centropomus undecimalis). Their regulatory role continues to be a subject of discussion since it varies, depending on multiple characteristics such as the reproductive strategies of the species in question and/or the conditions in which these were maintained during the study period. It has been descri...
