What causes a child to grow up gay or straight? In this book, neuroscientist Simon LeVay summarizes a wealth of scientific evidence that points to one inescapable conclusion: Sexual orientation results primarily from an interaction between genes, sex hormones, and the cells of the developing body and brain. LeVay helped create this field in 1991 with a much-publicized study in Science, where he reported on a difference in the brain structure between gay and straight men. Since then, an entire scientific discipline has sprung up around the quest for a biological explanation of sexual orientation. In this book, LeVay provides a clear explanation of where the science stands today, taking the reader on a whirlwind tour of laboratories that specialize in genetics, endocrinology, neuroscience, cognitive psychology, evolutionary psychology, and family demographics. He describes, for instance, how researchers have manipulated the sex hormone levels of animals during development, causing them to mate preferentially with animals of their own gender. LeVay also reports on the prevalence of homosexual behavior among wild animals, ranging from Graylag geese to the Bonobo chimpanzee.

Researchers of human behavior have identified an "orgasm gap": Men usually orgasm during intercourse, whereas women often do not. This book addresses this mystery. The two leading explanations are either that women are "psychologically broken"—Freud's theory—or badly designed—the "by-product theory." However, there is a much more compelling third explanation. Evolutionary biology, anatomy, physiology, and direct sex research suggest women have evolved under their own selection pressures and orgasm is a fitness-increasing consequence of such selective factors.

Sex Therapy with Erotically Marginalized Clients: Nine Principles of Clinical Support provides a clinical guide to relational sex therapy with individuals, partnerships, polyships, and alternative family structures where one or more of the clients are erotically marginalized. The book bridges gaps between the past, present, and future in the field of sex therapy and greatly expands the diversity of experiences and identities within the field, particularly the experience of multiple oppressions.

As W. A. Harris guides you through the process of how the brain is built, he takes up the biggest questions that scientists have asked about the developing brain.

Sex, Time, and Power offers a tantalizing answer to an age-old question: Why did big-brained Homo sapiens suddenly emerge some 150,000 years ago? The key, according to Shlain, is female sexuality. Drawing on an awesome breadth of research, he shows how, long ago, the narrowness of the newly bipedal human female's pelvis and the increasing size of infants' heads precipitated a crisis for the species. Natural selection allowed for reconfiguration of hormonal cycles, entraining women with the periodicity of the moon - and imbuing women with the concept of time.

Written by Daniel Nettle - author of the popular book Happiness - this brief volume takes the listener on an exhilarating tour of what modern science can tell us about human personality. Revealing that our personalities stem from our biological makeup, Nettle looks at the latest findings from genetics and brain science, and considers the evolutionary origins and consequences of different personalities. The heart of the book sheds light on the "big five": Extraversion, Neuroticism, Conscientious, Agreeableness, and Openness.

Psychologists often paint a picture of human mating as visceral, instinctual. But that's not the whole story. In courtship and display, sexual competition and rivalry, we are also guided by what Glenn Geher and Scott Barry Kaufman call Mating Intelligence - a range of mental abilities that have evolved to help us find the right partner. Mating Intelligence is at work in our efforts to form, maintain, and end relationships. It guides us in flirtation, foreplay, copulation, finding and choosing a mate, and many other behaviors.
