What causes a child to grow up gay or straight? 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 takes 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. In this second edition, LeVay adds a chapter on bisexuality, reviews some uncommon forms of sexuality, and considers whether there could be a biological basis for subtypes of gay people such as "butch" and "femme" lesbians.

The discovery of life on other planets would be perhaps the most momentous revelation in human history, more disorienting and more profound than either the Copernican or Darwinian revolutions, which knocked the earth from the center of the universe and humankind from its position of lofty self-regard. In Here Be Dragons, astronomer David Koerner and neurobiologist Simon LeVay offer a scientifically compelling and colorful account of the search for life beyond Earth. The authors survey the work of biologists, cosmologists, computer theorists, NASA engineers, SETI researchers, roboticists, and UFO enthusiasts and debunkers as they attempt to answer the greatest remaining question facing humankind: Are we alone? From their "safe haven of skepticism" the authors venture into the "rough seas of speculation," where theory and evidence run the gamut from hard science to hocus pocus. Arguing that the universe is spectacularly suited for the evolution of living creatures, Koerner and LeVay give us ringside seats at the great debates of Big Science. The contenitous arguments about what really happens in evolution, the acrimonious UFO controversy, and the debate over intelligence versus artificial intelligence shed new light on the wildly divergent claims about the universe and life's place in it. The authors argue that while no direct evidence of extraterrestrial life yet exists, habitats and chemical building blocks for life abound in the universe. A wealth of new astronomical techniques and space missions may provide this evidence early in the next century. Lucidly written and scientifically rigorous, Here Be Dragons presents everything we know thus far about the emergence of intelligent life here on earth and, perhaps, beyond.

Discovering Human Sexuality

An evidence-based, accessible introduction to the study of sexuality and the diverse ways in which it brings joys and challenges to our lives. Now in its fifth edition, Discovering Human Sexuality has established itself as a popular and widely praised text that respects diversity both in thesexual world and among the students who read it. The backgrounds of the authors - in biology, sociology, teaching, and writing - have made possible a text that is multidisciplinary, authoritative, sex-positive, and a delight to read.The scope of Discovering Human Sexuality ranges from homosexuality in ancient Greece to the recent Harvey Weinstein sexual harassment scandal while covering a stunningly diverse array of topics. Questions considered include: How does the menstrual cycle work? What's "splitting the bamboo"? Canpremature ejaculation be treated? If a man has undetectable levels of HIV, can he have sex without condoms? Which sex offenders will repeat their crimes? Is there a gay gene? What's wrong with polygamy? Is emergency contraception abortion? This book gives factual answers to important questions andprovides material for informed debate for issues without a single solution.

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. Although many details remain unresolved, the general conclusion is quite clear: A person's sexual orientation arises in large part from biological processes that are already underway before birth. LeVay also makes it clear that these lines of research have a lot of potential because--far from seeking to discover "what went wrong" in the lives of gay people, attempting to develop "cures" for homosexuality, or returning to traditional explanations that center on parent-child relationships, various forms of "training," or early sexual experiences--our modern scientists are increasingly seeing sexual variety as something to be valued, celebrated, and welcomed into society.

Sex, after hunger, may be the most powerful motivating force in our lives. It drives us to seek intimate contact with others and to form relationships that may be fleeting or lifelong, blissful or troubled. Yet many mysteries surround sex and sexuality: Why don’t we reproduce by virgin birth? Why does so much of our sexual behavior have nothing to do with reproduction? Why isn’t everyone heterosexual? How does the brain create sexual arousal? How do sexual kinks develop? Is porn harmful? What is the relationship between sex and love?\nIn Attraction, Love, Sex, the renowned scholar Simon LeVay introduces readers to a memorable cast of researchers trying to answer these questions and many more. A biologist dredges a New Zealand lake for asexual mud snails. Psychologists measure whether eating a good meal changes a man’s idea of female beauty. Physiologists probe orifices with miniature toilet plungers and place lovers in brain scanners. Geneticists reconstruct the sex crimes of Genghis Khan. Neuroscientists create mice whose sexual behavior can be switched on and off. A zoologist traps and releases 260,000 voles and launches a new science of love.\nLeVay distills vast expertise on the biology and psychology of sex into an engaging and easy-to-understand survey with scientific acumen, a critical eye, and a sense of humor. This book reveals how scientists are unraveling the secrets of sex and, in the process, shattering many traditional ideas and prejudices.

Written with the same clarity, directness, and humor that have made Simon LeVay one of the most popular lecturers at Harvard Medical School and at the University of California, San Diego, The Sexual Brain examines the biological roots of human sexual behavior. It puts forward the compelling case that the diversity of human sexual feelings and behavior can best be understood in terms of the development, structure, and function of the brain circuits that produce them. Discarding all preconceptions about the motivation and purpose of sexuality, LeVay discusses the scientific evidence bearing on such questions as why we are sexual animals, what the brain mechanisms are that produce sexual behavior, how these mechanisms differ between men and women and how these differences develop, and finally, what determines a person's sexual orientation: genes, prenatal events, family environment, or early sexual experiences? The Sexual Brain is broad in scope, covering evolutionary theory, molecular genetics, endocrinology, brain structure and function, cognitive psychology, and development. It is unified by LeVay's thesis that human sexual behavior, in all its diversity, is rooted in biological mechanisms that can be explored by laboratory science. The book does not shy away from the complexities of the field, but it can be readily appreciated and enjoyed by anyone with an intelligent interest in sex. Simon LeVay, whose 1991 paper published in Science, "A difference in hypothalamic structure between homosexual and heterosexual men," attracted worldwide scientific and public attention, is Associate Professor at the Salk Institute for Biological Studies and Adjunct Professor of Biology at the University of California, San Diego. He is presently Chair of the Steering Committee of the Institute of Gay and Lesbian Education, West Hollywood, a new college for the gay and lesbian community in Southern California.

City of Friends offers a practical, intelligent, and well-informed overview of what it means to be gay or lesbian. The authors seek to help gay men and women, as well as their families and friends, to better understand the institutions and communities that make up the most culturally and ethnically diverse minority in America today.Beginning with basic concepts, LeVay and Nonas define the words "homosexual," "gay," "lesbian," and "bisexual" and discuss the various patterns of homosexuality in different cultures around the world. They relate the history of the gay and lesbian community in the United States, and its struggle for equal rights and social acceptance, before tackling the question -- still highly controversial -- of what determines an individual's sexual orientation.City of Friends describes the great diversity within the gay and lesbian community: Life in the "gay ghetto." Old lesbians in rural hideaways. Gay resorts. A "town without men." Gay and lesbian Latinos, African-Americans, Asian-Americans, and Native Americans -- what it means to be a minority within a minority. Lesbian and gay youth, the elderly, the deaf. Bisexuals and transsexuals. Academics, drag queens, technoqueers, publishers, softball players -- all make their appearance in these pages.LeVay and Nonas continue with a discussion of health issues (especially of the AIDS epidemic and the community's response to it), the law, and gay and lesbian politics. They describe the cultural achievements of lesbians and gay men -- their art, literature, theater, music, and dance. Finally they take a look at the spiritual life of gays and lesbians, both within and outside of organized religion.
