一些动物和人类研究显示了肠道微生物群的性别差异,但结果并不一致。通讯生物学》(Communications Biology)杂志上的一项研究通过比较青春期前后雌雄小鼠的肠道微生物群,就睾酮和性别对小鼠肠道微生物群的影响提供了新的见解。结果表明,雌雄小鼠的微生物组组成存在差异,这种差异只有在青春期后才能看到。值得注意的是,进入青春期后,雄性小鼠的梭状芽孢杆菌属相对丰度高于雌性小鼠,而雌性小鼠的弧菌属丰度更高,弧菌属与小鼠抑郁和肥胖有关。在探索体内补充睾酮的影响时,研究人员发现睾酮会影响雄性和雌性小鼠的肠道微生物群和代谢组。这些结果表明,青春期后微生物群发生了变化,部分原因是体内性激素(主要是睾酮)水平升高:Moadi, L. et al.7, 880 (2024)
