title: Hot male: can sex in humans be modified by temperature?
abstract: Sex determination in many animals has an environmental component, particularly through temperature. In this article, it is argued that some evidence may by seen for this in humans, and it is proposed that the influence of temperature on sex determination may be a reason for the placing of testicles outside the body cavity in most male mammals.
