I begun to think again about sport and hormones and managed my disappointment by  trying to make sense of the contradictory role that testosterone plays,  in male lives particularly but also in females. A recent study   by  Leander van der Meij of the VU University, Amsterdam showed that testosterone levels increase when watching football matches, and the researchers suggest that this is linked to the response to threat and to dominance levels [1]. Indeed another study just published showed that males when given artificial does of testosterone stare for longer at faces which represent threat, even when these faces are out of awareness[2]. We have known for a while that sports players have higher levels when playing at home and when playing fierce rivals, and even found that male  Obama supporters had higher levels than McCain supporters on the night when the last presidential election results were announced. Such research gets right to the heart of much nature-nurture debate. While we are often saddled with our testosterone levels from pre-birth, and indeed much research suggests that prenatal testosterone levels influences a range of behaviours from sexual choice to the toys we play with, levels rise and fall in response to specific circumstances and in all likelihood particular cultural influences. Southern American men, for example, tend to respond more reactively to potential threat than their northern counterparts.
