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.
An evolutionary psychologist explains how present-day sexual and romantic behavior reflect two million years of hominid evolution.
Ambition, genius, thought, imagination, love, hate, greed and, above all, consciousness ourselves as alive and as part of our world OCo all this is somehow enabled by the brain. The brain is the person, and if it goes wrong, a person is ruined. This book is about part of what the brain does OCo a role of which many of us are hardly aware, but one that has ensured, the survival of mankind. Despite famine, drought, wars, cold, infections and hostile environments, we survive as a species OCo though not always as individuals. All this time, our brains have been coping with what fate throws at us OCo a process that some call adaptation. How does the brain do it? How does it know whatOCOs needed? How does it enable us to provide that need? How much do we depend on our own brains, or on those of others?. This book is different from other books on the brain. It deals with the brainOCOs role in survival, rather than OC higherOCO cognitive functions (such as language or thought). It describes the special part of the brain that keeps you alive: that makes you feel hungry when you need energy, makes you feel thirsty when you need water, drives you to reproduce so that your species survives, makes you fearful of things or individuals that might harm you, and defends you against adversity."

Sexual orientation (homo- vs. heterosexuality) is one of many sex differences observed in humans. Sex differences can result from differential postnatal experiences (interaction with parents, environment) or from biological factors (hormones and genes) acting pre- or postnatally. The first option is often favored to explain sexual orientation although it is supported by little experimental evidence. In contrast, many sexually differentiated behaviors are organized during early life by an irreversible action of sex steroids. In particular, the preference for a male or female sex partner is largely determined in rodents by embryonic exposure to sex steroids. The early action of these steroids also seems to affect sexual orientation in humans. Indeed, clinical conditions associated with major endocrine changes during embryonic life often result in an increased incidence of homosexuality. Furthermore, multiple sexually differentiated behavioral, physiological, or even morphological traits that are known to be organized by prenatal steroids, at least in animals, are significantly different in homo- and heterosexual populations. Thus, prenatal endocrine (or genetic) factors seem to influence significantly human sexual orientation even if a large fraction of the variance remains unexplained to date. The possible interaction between biological factors acting prenatally and postnatal social influences remains to be investigated.
During the last years human sexuality has been the focus of interest and study by various disciplines. In this volume a multidisciplinary team of international experts discuss contemporary issues of human sexuality from updates on diagnosis to the management of various sexual dysfunctions. Reviews of the management of several female sexual dysfunctions, the impact of cancer on sexual functioning, the impact of trauma on sexual desire and function as well as the newest trends in sex therapy; androgen deprivation treatment of sexual behavior and autogynephilia are discussed in detail.

“Mark has eloquently unraveled the mystery behind addictive behavior: when our relationships are not alive and growing, the temptation for various kinds of addictions is unleashed..”—Dr. Gary Smalley With today’s rampant availability of Internet pornography, sexual addiction has become a national epidemic that affects up to 10 percent of Christians. As devastating as any drug habit, it brings heartbreak and despair to those it entangles. But there is help for men and women caught in sexual addiction’s downward spiral. This book offers a path that leads beyond compulsive thoughts and behaviors to healing and transformation. Sensitive to the shame of sexual addiction without minimizing its sinfulness, Dr. Mark Laaser traces the roots of the problem, discusses its patterns and impact, and maps out a biblical approach to self-control and sexual integrity. Previously titled Faithful and True, this revision includes an all-new section that deals with sexual addiction in the church. Other important changes reflect cultural trends, incorporate current research, and place a greater emphasis on spiritual growth. This book also addresses the unique needs and issues of female sex addicts. Whether you know someone with a sexual addiction or struggle yourself, Healing the Wounds of Sexual Addiction points the way to understanding, wholeness, and holiness.
This book bridges psychoanalytic thought and sexual science. It brings sexuality back to the center of psychoanalysis and shows how important it is for students of human sexuality to understand motives that are often irrational and unconscious. The authors present a new perspective about male and female development, emphasizing the ways in which sexual orientation and homophobia appear early in life. The clinical section of the book focuses on the psychodynamics and treatment of homophobia and internalized homophobia.

Sexual difference in the brain has long been one of the more intriguing research areas in the field of neuroscience. This thorough and comprehensive text uncovers and explains recent neurobiological and molecular biological studies in the field of neuroscience as they relate to the mechanisms underlying sexual differentiation of the brain. Attempts have been made to clarify sex differences in the human brain using noninvasive techniques such as magnetic resonance imaging. Sexual Differentiation of the Brain thoroughly examines these techniques and findings, providing an up-to-date, comprehensive overview written by leading researchers in the field. Just a few of the topics addressed include genetic contributions to the sexual differentiation of behavior; in-vitro studies of the effects of estrogen on estrogen receptor-transfected neuroblastoma cells; and the evolution of brain mechanisms controlling sexual behavior. Other topics include sexual differentiation of neural circuitry in the hypothalamus; structural sex differences in the mammalian brain; and sexual differentiation of cognitive functions in humans. With its revealing and informative chapters, as well as provocative treatment of the subject matter, Sexual Differentiation of the Brain helps shed new light on one of the most fascinating areas of brain research.
2013 Honorable Mention, Asian American Studies Association's prize in Literary Studies Part of the American Literatures Initiative Series Why do black characters appear so frequently in Asian American literary works and Asian characters appear in African American literary works in the early twentieth century?Interracial Encounters attempts to answer this rather straightforward literary question, arguing that scenes depicting Black-Asian interactions, relationships, and conflicts capture the constitution of African American and Asian American identities as each group struggled to negotiate the racially exclusionary nature of American identity. In this nuanced study, Julia H. Lee argues that the diversity and ambiguity that characterize these textual moments radically undermine the popular notion that the history of Afro-Asian relations can be reduced to a monolithic, media-friendly narrative, whether of cooperation or antagonism. Drawing on works by Charles Chesnutt, Wu Tingfang, Edith and Winnifred Eaton, Nella Larsen, W.E.B. Du Bois, and Younghill Kang, Interracial Encounters foregrounds how these reciprocal representations emerged from the nation’s pervasive pairing of the figure of the “Negro” and the “Asiatic” in oppositional, overlapping, or analogous relationships within a wide variety of popular, scientific, legal, and cultural discourses. Historicizing these interracial encounters within a national and global context highlights how multiple racial groups shaped the narrative of race and national identity in the early twentieth century, as well as how early twentieth century American literature emerged from that multiracial political context.
Designed for both the undergraduate and graduate classroom, this selection of important articles provides a comprehensive overview of current thought about the psychological issues affecting lesbians, bisexuals, and gay men.

The Fourth Edition of Knobil & Neill continues to serve as a reference aid for research, to provide the historical context to current research, and most importantly as an aid for graduate teaching on a broad range of topics in human and comparative reproduction. In the decade since the publication of the last edition, the study of reproductive physiology has undergone monumental changes. Chief among these advances are in the areas of stem cell development, signaling pathways, the role of inflammation in the regulatory processes in the various tissues, and the integration of new animal models which have led to a greater understanding of human disease. The new edition synthesizes all of this new information at the molecular, cellular, and organismal levels of organization and present modern physiology a more understandable and comparative context. The Fourth Edition has been extensively revised, reflecting new fundamental advancements in this rapidly advancing field. Provides a common language for researchers across the fields of physiology, endocrinology, and biology to discuss their understanding of reproduction. Saves academic researchers time in quickly accessing the very latest details on reproductive physiology, as opposed to searching through thousands of journal articles.
Most people value to have children still highly. But what is the optimal moment to have the first? The decision on having children or not and if yes on the timing of the first is one of the most difficult ones to make, also because it more or less coincides with various other heavy decisions on shaping the life course (like on union formation, labour market career, housing accommodation, etc.). People realise that having children will fundamentally change their life and in order to fit this unknown and irreversible adventure perfectly into their life course postponement of the first birth is an easy way out as long as doubts continue and partners try to make up their mind. Modern methods of birth control are of course a very effective help in that period. What is the best moment to have the first child? And to what moment is postponement justified? There are no easy answers to these questions. Best solutions vary per person as they depend on personal circumstances and considerations (the partner may have conflicting ideas; housing accommodation; job; income; free time activities). Existing parental leave and child care arrangements are weighted as well. Unfortunately the biological clock ticks further. And, also unfortunately, assisted reproductive technology (IVF etc.) is unable to guarantee a successful outcome. Several couples end up without children involuntarily and that may lead to sorrow and grief. This interdisciplinary book overviews the process of postponement and its backgrounds in modern Western societies holistically, both at the personal and the societal level. Contributions come from reproductive, evolutionary biological and neurological sciences, as well as from demography, economy, sociology and psychology. It holds not only at women but also at men becoming first time fathers. The discussion boils down to a new policy approach for motherhood and emancipation on how to shape work and family life? It is argued that a public window where one can compose a ‘cafeteria’-like set of supportive arrangements according to personal preferences could lead to a break in the rising age at first motherhood.
