A highly accessible owner's manual for every man, and a cheat sheet for every woman.

From the author of the groundbreaking, international bestseller The Female Brain comes this eagerly awaited follow-up.

Did you know that the male brain...

is a lean, mean problem-solving machine that uses analytical brain structures, not emotional ones, to find solutions

thrives under competition, instinctively plays rough, and is obsessed with rank and hierarchy

has an area for sexual pursuit that is 2.5 times larger than that of the female brain, consuming him with sexual fantasies about female body parts

As Dr Louann Brizendine's impeccably researched, irresistible guide follows the male brain from infancy to adulthood, it unlocks many secrets and offers fascinating insights into a range of subjects, including emotional intimacy, anger, agression, and winning. It also answers many baffling questions and exposes the often shocking gulf that exists between the sexes.
