About the book

Testosterone, so we’re told, is the very essence of masculinity, and biological sex is a fundamental force in our development. Not so, says psychologist Cordelia Fine, who shows, with wit and panache, that sex doesn’t create male and female natures. Instead, sex, hormones, culture and evolution work together in ways that make past and present gender dynamics only a serving suggestion for the future – not a recipe. Testosterone Rex brings together evolutionary science, psychology, neuroscience and social history to move beyond old ‘nature versus nurture’ debates, and to explain why it’s time to unmake the tyrannical myth of Testosterone Rex.

For fans of Fine – whose Delusions of Gender ‘could have far-reaching consequences as significant as The Female Eunuch’ (Viv Groskop, Guardian) – and thousands of new readers, this is an upbeat, timely and important contribution to the debate about gender in society.
