Background: The initiation of puberty is dependent upon an augmentation of gonadotropin-releasing hormone (GnRH) secretion from the hypothalamus. Development of the GnRH neuroendocrine network in embryonic life depends on coordinated migration of neurons from the vomeronasal organ in the nose to the forebrain. We have previously demonstrated that dysregulation in GnRH neuronal migration leads to delayed pubertal onset. Late puberty affects up to 2% of the ...
