中枢神经系统的性别二态性存在于许多脊椎动物物种中，并且在许多情况下，雄性和雌性之间的这些结构差异与生殖行为表现上的差异相似。通常，行为和解剖学差异都是通过在个体发育期间或成年期间接触性腺类固醇激素来控制的。本文回顾了支持这一假设的一些证据，即在哺乳动物中，睾酮或其代谢物调节参与控制男性性行为的神经和肌肉系统的结构和功能。然后，它描述了一些数据，表明斑胸草雀和绿变色龙蜥蜴两性异形求爱系统的调节机制与哺乳动物系统并不完全平行。最后，提出了未来研究的一些方向，希望当研究人员试图确定哪些形态性别差异对控制生殖行为很重要，以及哪些调节结构和功能的机制被广泛采用或独特时，它们能够激发人们对脊椎动物模型之间比较的性质的思考。
Sexual dimorphisms in the central nervous system exist in numerous vertebrate species, and in many cases these structural differences between males and females parallel differences in the display of reproductive behaviors. Often both the behavioral and anatomical differences are controlled by exposure to gonadal steroid hormones, either during ontogeny or in adulthood. This article reviews some of the evidence supporting the hypothesis that in mammals, testosterone or its metabolites regulate the structure and function of neural and muscle systems involved in the control of masculine sexual behaviors. It then describes data suggesting that the mechanisms regulating sexually dimorphic courtship systems in zebra finches and green anole lizards are not completely parallel to the mammalian systems. Finally, some directions for future study are suggested, with the hope that they will stimulate thought about the nature of comparisons made across vertebrate models when investigators are attempting to determine both which morphological sex differences are important to the control of the reproductive behaviors, and which mechanisms regulating both structure and function are widely employed or are unique.
