This fascinating new book explores the myriad aspects of biological theories of sexual preference. Sex, Cells, and Same-Sex Desire describes, reviews, and questions recent biological research on sexual preference from the point of view of knowledgeable scientists and of scholars in the social sciences and humanities representing the emerging field of gay studies. The issues involved have a vibrant history, are wide-ranging, and remain the objects of much controversy. This book demystifies biological research on sexual preference and makes it accessible to readers unfamiliar with biological and medical research.Sex, Cells, and Same-Sex Desire is divided into several sections, each of which is introduced by an explanation of key concepts and terms found in that section. The book begins with a discussion of the history of biological theories and sociocultural concepts of gender and sexuality. The next 3 sections explore specialized areas of biological science and related issues: genetics and evaluation, hormones and the endocrine system, and brain physiology and structure. A final section discusses social stigma, science, and medicine. A glossary of terms used by the authors is included, so readers may look up those that may be unfamiliar.

It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.

Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism—ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediating intraspecific communication. Providing an up-to-date outline of the most recent advances in the field, it presents data from laboratory and wild species, ranging from invertebrates to vertebrates, from insects to humans. The book examines the structure, anatomy, electrophysiology, and molecular biology of pheromones. It discusses how chemical signals work on different mammalian and non-mammalian species and includes chapters on insects, Drosophila, honey bees, amphibians, mice, tigers, and cattle. It also explores the controversial topic of human pheromones. An essential reference for students and researchers in the field of pheromones, this is also an ideal resource for those working on behavioral phenotyping of animal models and persons interested in the biology/ecology of wild and domestic species.

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.

Why are you attracted to a certain "type?" Why are you a morning person? Why do you vote the way you do? From a witty new voice in popular science comes a clever, life-changing look at what makes you you. "I can't believe I just said that." "What possessed me to do that?" "What's wrong with me?" We're constantly seeking answers to these fundamental human questions, and now, science has the answers. The foods we enjoy, the people we love, the emotions we feel, and the beliefs we hold can all be traced back to our DNA, germs, and environment. This witty, colloquial book is popular science at its best, describing in everyday language how genetics, epigenetics, microbiology, and psychology work together to influence our personality and actions. Mixing cutting-edge research and relatable humor, Pleased to Meet Me is filled with fascinating insights that shine a light on who we really are--and how we might become our best selves.

In recent years, scientific research & popular opinion have favoured the idea that sexual orientations are determined at birth, but Edward Stein argues that this may be wrong. This book offers an examination of contemporary thinking on this issue.

Women's health, as a field of study, is a developing discipline. Health theories in general have been based on studies of men. However, in recent years, more attention has shifted to women's health, realizing the disparities between men and women in relation to their health. During the last two decades, a similar shift has occurred for a group of womenâ€"lesbian womenâ€"to further identify and specify their health needs. Over the past decade, lesbians have organized to call for attention to the health issues of this community, resulting in several federally funded research initiatives. This book offers a comprehensive view of what is known about lesbian health needs and what questions need further investigation, including: How do we define who is lesbian? Are there unique health issues for lesbians? Are lesbians at higher or lower risk for such health problems as AIDS, sexually transmitted diseases, breast cancer, mental disorders, and substance abuse? How does homophobia affect lesbian health and the funding of research on lesbian health? How do lesbian health needs fit into the health care system and the larger society? What risk and protective factors shape the physical and mental health of lesbians? The book discusses how to determine which questions to ask about sexual orientation, the need to obtain information without violating privacy, the importance of considering racial and ethnic diversity in the study of lesbians, strategies for exchanging information among researchers and disseminating findings to the public, and mechanisms for supporting greater numbers of researchers. Lesbian Health takes a frank look at the political pressures, community attitudes, and professional concerns uniquely affecting the study of lesbian health issues. The book explores many other issues including the potential for transferring findings in this field to other population groups, including other rare populations and women in general.
