How Sex Works

Why are women biologically driven to find Mr. Tall, Dark, and Handsome? Can more sex help ensure a safe pregnancy? What effect does pornography have on a man's fertility? Dr. Sharon Moalem, author of the New York Timesbestseller Survival of the Sickest, takes us on a trip from prehistory to the forefront of cutting-edge medical research'and through a bedroom or two'to tell the story of how human sexuality has developed over time. How Sex Workschallenges common perceptions about our bodies as it provides answers to such provocative questions as: Can the birth control pill influence the type of men women are attracted to? Why do hourglass-shaped women tend to be especially fertile? When are women most likely to cheat? Can twins have different fathers? From the composition and function of human sex organs to the fascinating biochemistry behind sexual attraction, How Sex Worksis an entertaining, comprehensive exploration of culture, biology, and history that takes us far beyond our common understanding of sex.
