Derelitto Posted November 8, 2010 Share Posted November 8, 2010 I'm having a debate with someone, and something my opponent stated struck me as flat wrong, but I'm unsure how to respond. His statement was: 'For all mammalian species, females have less testosterone than males.' Hyenas are an obvious exception to this universalising statement which I will bring up in due course, but I can't think of any other species. Are there any other species of mammal in which the females exhibit higher levels of testosterone than males? I need more than just a single 'exception' to his claim. Thanks! --Derelitto Link to comment Share on other sites More sharing options...
