Testosterone : the story of the hormone that dominates and divides us / Carole Hooven

Includes bibliographical references and index.

Testosterone is the most mythologized and misunderstood hormone, but Harvard evolutionary biologist Carole Hooven offers riveting human stories and cutting-edge research to reveal the far-reaching effects of testosterone on our brains, bodies and behaviour. 'With all the talk about testosterone in sex, sports and politics, we need a good explanation of the science and its implications, and this one is outstanding.' Steven Pinker, bestselling author of The Blank Slate The biological source of masculinity has inspired fascination, investigation and controversy since antiquity. From the eunuchs in the royal courts of ancient China to the booming market for 'elixirs' of youth in nineteenth-century Europe, humans have been obsessed with identifying and manipulating what we now know as testosterone. And the trends show no signs of slowing down. The modern market for testosterone supplements is booming. Thanks to this history and the methods of modern science, today we have a rich body of research about testosterone's effects in both men and women. The science is clear: testosterone is a major, invisible player in our relationships, sex lives, athletic abilities, childhood play, gender transitions, parenting roles, violent crime, and so much more. But there is still a lot of pushback to the idea that it does, in fact, cause sex differences and significantly influences behaviour. Hooven argues that acknowledging testosterone as a potent force in society doesn't reinforce stifling gender norms or patriarchal values. Testosterone and evolution work together to produce a huge variety of human behaviour, and that includes a multitude of ways to be masculine and feminine. Understanding the science sheds light on how we work and relate to one another, how we express anger and love, and how we fight bias and problematic behaviour to build a fairer society
