Based on phylogenetic analysis, this paper reviewed the relationship between hormones including sex hormones and AVT, and vocal production and perception through all anuran species studied to date. We found that in anuran brains the AVT system related to vocal behaviors were very conservative while the sex hormone systems involved in vocal communication might be originated independently from varied taxa of anuran.
