Testosterone: An Unauthorized Biography

Overview

Testosterone is a familiar villain, a ready culprit for everything from stock market crashes to the overrepresentation of men in prisons. That’s a lot to pin on a simple molecule.

This unauthorized biography pries the much-maligned T free from over a century of misconceptions.
