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.

Few things come more naturally to us than sex—or so it would seem. Yet to a chimpanzee, the sexual practices and customs we take for granted would appear odd indeed. He or she might wonder why we bother with inconveniences like clothes, why we prefer to make love on a bed, and why we fuss so needlessly over privacy. Evolution and Human Sexual Behavior invites us into the thought-experiment of imagining human sex from the vantage point of our primate cousins, in order to underscore the role of evolution in shaping all that happens, biologically and behaviorally, when romantic passions are aroused. Peter Gray and Justin Garcia provide an interdisciplinary synthesis that draws on the latest discoveries in evolutionary theory, genetics, neuroscience, comparative primate research, and cross-cultural sexuality studies. They are our guides through an exploration of the patterns and variations that exist in human sexuality, in chapters covering topics ranging from the evolution of sex differences and reproductive physiology to the origins of sexual play, monogamous unions, and the facts and fictions surrounding orgasm. Intended for generally curious readers of all stripes, this up-to-date, one-volume survey of the evolutionary science of human sexual behavior explains why sexuality has remained a core fascination of human beings throughout time and across cultures.

Adolescenceâ€"beginning with the onset of puberty and ending in the mid-20sâ€"is a critical period of development during which key areas of the brain mature and develop. These changes in brain structure, function, and connectivity mark adolescence as a period of opportunity to discover new vistas, to form relationships with peers and adults, and to explore one's developing identity. It is also a period of resilience that can ameliorate childhood setbacks and set the stage for a thriving trajectory over the life course. Because adolescents comprise nearly one-fourth of the entire U.S. population, the nation needs policies and practices that will better leverage these developmental opportunities to harness the promise of adolescenceâ€"rather than focusing myopically on containing its risks. This report examines the neurobiological and socio-behavioral science of adolescent development and outlines how this knowledge can be applied, both to promote adolescent well-being, resilience, and development, and to rectify structural barriers and inequalities in opportunity, enabling all adolescents to flourish.

Exploring The Dimensions Of Human Sexuality, Third Edition, Has Been Extensively Updated To Include Information And Statistics About Recent Developments. This Text Continues To Encourage Students To Explore The Varied Dimensions Of Sexuality And To See How Each Affects Their Personal Sexuality, Sexual Health, And Sexual Responsibility. All Aspects Of Sexuality--Biological, Spiritual, Psychological, And Sociocultural--Are Presented Factually And Impartially.

"Masters and Johnson's basic groundwork in sex physiology will now make it possible for medicine to assume a rsponsibility it has neglected far too long - that of educating its own. Through the authors' efforts, those responsible for sex education finally have before them clinical facts about one of the more vital aspects of human existence. [This volume] is primarily concerned with the sexual response cycles of men and women between the ages of 21 and 50, with emphasis on similarities rather than differences in their sexual response patterns."--Excerpt from the Publisher's Description.

Although sexual psychophysiology has made great strides over the past few decades, the progress made has not been accompanied by much effort to integrate research findings or to stimulate methodological and theoretical discussions among researchers. Yet this new research area has the potential to make substantial contributions to understanding a wide range of phenomena, including the spread of HIV/STIs, sexual "addiction" or compulsivity, the use (or nonuse) of birth-control methods, sexual infidelity, and aggressive sexual behaviors. Psychophysiological methods can assist in the exploration of the underlying psychological, physiological, and affective processes, and, perhaps more importantly, how they interact. In this volume, editor Erick Janssen brings together wide-ranging essays written by an authoritative group of researchers, representing the cutting edge of sexual psychophysiology.

Adolescence is one of the most fascinating and complex transitions in the human life span. Its breathtaking pace of growth and change is second only to that of infancy. Over the last two decades, the research base in the field of adolescence has had its own growth spurt. New studies have provided fresh insights while theoretical assumptions have changed and matured. This summary of an important 1998 workshop reviews key findings and addresses the most pressing research challenges.

Pedagogies of Possibility for Negotiating Sexuality Education with Young People offers a sustained and critical consideration of the possibilities and politics of engaging with young people in the redevelopment and delivery of contemporary approaches to Sexuality Education.

Young adulthood - ages approximately 18 to 26 - is a critical period of development with long-lasting implications for a person's economic security, health and well-being. Young adults are key contributors to the nation's workforce and military services and, since many are parents, to the healthy development of the next generation. Although 'millennials' have received attention in the popular media in recent years, young adults are too rarely treated as a distinct population in policy, programs, and research. Instead, they are often grouped with adolescents or, more often, with all adults. Currently, the nation is experiencing economic restructuring, widening inequality, a rapidly rising ratio of older adults, and an increasingly diverse population. The possible transformative effects of these features make focus on young adults especially important. A systematic approach to understanding and responding to the unique circumstances and needs of today's young adults can help to pave the way to a more productive and equitable tomorrow for young adults in particular and our society at large. Investing in The Health and Well-Being of Young Adults describes what is meant by the term young adulthood, who young adults are, what they are doing, and what they need. This study recommends actions that nonprofit programs and federal, state, and local agencies can take to help young adults make a successful transition from adolescence to adulthood. According to this report, young adults should be considered as a separate group from adolescents and older adults. Investing in The Health and Well-Being of Young Adults makes the case that increased efforts to improve high school and college graduate rates and education and workforce development systems that are more closely tied to high-demand economic sectors will help this age group achieve greater opportunity and success. The report also discusses the health status of young adults and makes recommendations to develop evidence-based practices for young adults for medical and behavioral health, including preventions. What happens during the young adult years has profound implications for the rest of the life course, and the stability and progress of society at large depends on how any cohort of young adults fares as a whole. Investing in The Health and Well-Being of Young Adults will provide a roadmap to improving outcomes for this age group as they transition from adolescence to adulthood.
