We inherit mechanisms for survival from our primeval past; none so obviously as those involved in reproduction. The hormone testosterone underlies the organization of activation of masculinity: it changes the body and brain to make a male. It is involved not only in sexuality but in driving aggression, competitiveness, risk-taking – all elements that were needed for successful survival and reproduction in the past. But these ancient systems are carried forward into a modern world. The ancient world shaped the human brain, but the modern world is shaped by that brain. How does this world, with all its cultural, political, and social variations, deal with and control the primeval role of testosterone, which continues to be essential for the survival of the species? Sex, aggression, winning, losing, gangs, war: the powerful effects of testosterone are entwined with them all. These are the ingredients of human history, so testosterone has played a central role in our story.
In Testosterone: Sex, Power, and the Will to Win, Joe Herbert explains the nature of this potent hormone, how it operates in mammals in general and in humans in particular, what we know about its role in influencing various aspects of behaviour in men, and what we are beginning to understand of its role in women. From rape to gang warfare among youths, understanding the workings of testosterone is critical to enable us to manage its continuing powerful effects in modern society.

Joe Herbert is Emeritus Professor of Neuroscience, Cambridge University and a Fellow of Gonville and Caius College. His areas of expertise include the role of hormones in the ability of the adult brain to make new nerve cells (neurons) and repair the brain; how hormones regulate behavior; the neuroscience of stress; how hormones, genes and the social and psychological environment interact to promote the risk for depression; and studies on the way that hormones and genes influence financial decision-making. He has authored (and co-authored) around 250 scientific papers on these topics, and is the author of The Minder Brain: How your brain keeps you alive, protects you from danger, and ensures that you reproduce (World Scientific Press, 2007).

"Testosterone is a very good read on an interesting subject"
– BBC Focus, Dr Dean Burnett
"Herbert's study makes clear that testosterone a small but powerful molecule has helped shape our history [...] Testosterone [...] provokes its readers into considering the role of our biological inheritance in influencing how we cope with modern society [...] Herbert challenges us to pay closer attention to the role of our biological inheritance in shaping virtually all aspects of our existence"
