This review emphasizes the comparative approach used to give insight into the knowledge related to cellular communications occurring in the hypothalamus-pituitary-gonadal axis.

Abstract

This review emphasizes the comparative approach used to give insight into the knowledge related to cellular communications occurring in the hypothalamus-pituitary-gonadal axis. Indeed, research on adaptive phenomena leads to evolutionary tracks. Thus, going through recent results, we suggest that pheromonal communication precedes local communication which, in turn, precedes communication via blood stream. Furthermore, the use of different routes of communication by a certain mediator leads to change concepts related to what hormones are. Nevertheless, endocrine communication should leave out of consideration the source (glandular or not) of mediator. Finally, we point out that the use of lower vertebrate animal models is fundamental to understand general physiological mechanisms. In fact, different anatomical organization permits access to tissues not readily approachable in mammals.
