recommendations! Published in 2020 at "Molecular Reproduction and Development"

DOI: 10.1002/mrd.23351

Abstract: Gonadotropin‐releasing hormone (GnRH) is a key molecule in the initiation of the hypothalamic–pituitary–gonadal axis. Thus, knowledge about GnRH may contribute to the effectiveness of species reproduction. Using a Neotropical tetra Astyanax altiparanae as a fish… read more here.
