Although the idea that women become raving lunatics when their hormones fluctuate is firmly entrenched in American culture, a thorough examination of the evidence overwhelmingly tells us otherwise. This provocative book exposes the pervasive myths about women's hormones-which lead to false beliefs about women's competence-by illustrating how flawed, obsolete research and sexism have combined to keep women "in their place," and skillfully shows how women can reject the "hormone myth" and own their emotions in a healthy and realistic way.
