已知控制PRL和促性腺激素分泌的神经机制在哺乳动物中存在性别差异。正常雄性大鼠的PRL分泌及促性腺激素分泌的神经调节呈非周期的紧张性分泌,而在雌鼠两种激素的分泌调节是周期性。据报道,参与控制PRL分泌的多巴胺和5-羟色胺在脑中的浓度及转换率存在着性别差异。促性腺激素在雄 There are known neural mechanisms that control the secretion of PRL and gonadotropin in mammals. The normal regulation of PRL secretion and gonadotropin secretion in normal male rats is aseptic and non-periodic secretion, and the secretion regulation of the two hormones is periodic in female rats. It has been reported that there is a gender difference in brain concentrations and conversion rates of dopamine and serotonin involved in the control of PRL secretion. Gonadotropin in the male
