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.
