This classic work on the rules of sex -- updated for a new generation -- is still as provocative as the day it was published, providing simple explanations for any and all questions about what happens in the bedroom. Sex isn't as complicated as we make it. In Sperm Wars, evolutionary biologist Robin Baker argues that every question about human sexuality can be explained by one simple thing: sperm warfare. In the interest of promoting competition between sperm to fertilize the same egg, evolution has built men to conquer and monopolize women while women are built to seek the best genetic input on offer from potential sexual partners. Baker reveals, through a series of provocative fictional scene, the far-reaching implications of sperm competition. 10% of children are not fathered by their "fathers;" over 99% of a man's sperm exists simply to fight off all other men's sperm; and a woman is far more likely to conceive through a casual fling than through sex with her regular partner. From infidelity, to homosexuality, to the female orgasm, Sperm Wars turns on every light in the bedroom. Now with new material reflecting the latest research on sperm warfare, this milestone of popular science will still surprise, entertain, and even shock.

A dirty bomb has been dropped and humanity is forever changed. The boys who didn't die stayed the same but the women grew into giantesses--walking gods as tall as the mountains. To remake a new and better world, all post-pubescent men were eaten and killed, and the remaining boys were rounded up to live in The Pen and learn to become better men. One of those boys, Tyson, waits on Eve Night--the night before the giantesses select who will be reborn through their womb. Men themselves are now sperm and each giantess selects ten of their favorite men to go inside her and compete to be the winner--reborn as a baby. Tyson wants the childhood that was taken away from him during World War III, but he must learn to work, fight, and help the 9 others if he wants to be a baby again. "De Sandra creates a world that plays with edible men, female anatomy, and misandry. This is the giantess fetish at its most lurid and comical, while quietly illustrating the poignant isolation of divided gender." Devora Gray, Author of Human Furniture and the Quest for the Perfect Woman

Profoundly persuasive, this controversial book sheds light on the darkest secrets of family life and reveals the deep, genetic reasons behind its outward irrationalities and the purpose underlying its most apparently destructive drives.

Behavioural ecologists and evolutionary biologists have long been interested in the biological implications of sperm from different males competing for fertilization of the egg in the female tract. This book discusses these implications for human sexual behaviour and human infertility problems.

"Robin Baker, an expert on evolution and human sexual behavior turns his attention to the reproductive revolution that is happening around us. Baker explains the technologies of assisted reproduction that are currently available and those likely to become available as we proceed in the twenty-first century: from in vitro fertilization and surrogate motherhood to cloning, gamete banking, and novel ways of micromanipulating sperm and egg, testes and ovaries."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

This book demonstrates how detailed comparative analyses of the anatomy, reproductive physiology, and behaviour of non-human primates and other mammals can offer profound insights into the origins of human sexual behaviour.
