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.

Are boys and girls really that different? Twenty years ago, doctors and researchers didn’t think so. Back then, most experts believed that differences in how girls and boys behave are mainly due to differences in how they were treated by their parents, teachers, and friends. It's hard to cling to that belief today. An avalanche of research over the past twenty years has shown that sex differences are more significant and profound than anybody guessed. Sex differences are real, biologically programmed, and important to how children are raised, disciplined, and educated. In Why Gender Matters, psychologist and family physician Dr. Leonard Sax leads parents through the mystifying world of gender differences by explaining the biologically different ways in which children think, feel, and act. He addresses a host of issues, including discipline, learning, risk taking, aggression, sex, and drugs, and shows how boys and girls react in predictable ways to different situations. For example, girls are born with more sensitive hearing than boys, and those differences increase as kids grow up. So when a grown man speaks to a girl in what he thinks is a normal voice, she may hear it as yelling. Conversely, boys who appear to be inattentive in class may just be sitting too far away to hear the teacher—especially if the teacher is female. Likewise, negative emotions are seated in an ancient structure of the brain called the amygdala. Girls develop an early connection between this area and the cerebral cortex, enabling them to talk about their feelings. In boys these links develop later. So if you ask a troubled adolescent boy to tell you what his feelings are, he often literally cannot say. Dr. Sax offers fresh approaches to disciplining children, as well as gender-specific ways to help girls and boys avoid drugs and early sexual activity. He wants parents to understand and work with hardwired differences in children, but he also encourages them to push beyond gender-based stereotypes. A leading proponent of single-sex education, Dr. Sax points out specific instances where keeping boys and girls separate in the classroom has yielded striking educational, social, and interpersonal benefits. Despite the view of many educators and experts on child-rearing that sex differences should be ignored or overcome, parents and teachers would do better to recognize, understand, and make use of the biological differences that make a girl a girl, and a boy a boy.

Female and male brains are different, thanks to hormones coursing through the brain before birth. That’s taught as fact in psychology textbooks, academic journals, and bestselling books. And these hardwired differences explain everything from sexual orientation to gender identity, to why there aren’t more women physicists or more stay-at-home dads. In this compelling book, Rebecca Jordan-Young takes on the evidence that sex differences are hardwired into the brain. Analyzing virtually all published research that supports the claims of “human brain organization theory,” Jordan-Young reveals how often these studies fail the standards of science. Even if careful researchers point out the limits of their own studies, other researchers and journalists can easily ignore them because brain organization theory just sounds so right. But if a series of methodological weaknesses, questionable assumptions, inconsistent definitions, and enormous gaps between ambiguous findings and grand conclusions have accumulated through the years, then science isn’t scientific at all. Elegantly written, this book argues passionately that the analysis of gender differences deserves far more rigorous, biologically sophisticated science. “The evidence for hormonal sex differentiation of the human brain better resembles a hodge-podge pile than a solid structure...Once we have cleared the rubble, we can begin to build newer, more scientific stories about human development.”

Geary (psychology and anthropology, U. of Missouri-Columbia) thinks culturally constructed gender roles alone cannot account for the differences in the social behavior of men and women. He turns to Darwin's theory of sexual selection as the best avenue for understanding. His main focus is how th etwo elements of competition between males and of females selecting mates has influenced human behavior over the centuries and across cultures.

This volume is the first to aim at summarizing all of the scientific literature published so far regarding male-female differences and similarities, not only in behavior, but also in basic biology, physiology, health, perceptions, emotions, and attitudes. Results from over 18,000 studies have been condensed into more than 1,900 tables, with each table pertaining to a specific possible sex difference. Even research pertaining to how men and women are perceived (stereotyped) as being different is covered. Throughout this book's eleven years in preparation, no exclusions were made in terms of subject areas, cultures, time periods, or even species. The book is accompanied by downloadable resources containing all 18,000+ references cited in the book. Sex Differences is a monumental resource for any researcher, student, or professional who requires an assessment of the weight of evidence that currently exists regarding any sex difference of interest. It is also suitable as a text in graduate courses pertaining to gender or human sexuality.

The fourth edition of Sex Differences in Cognitive Abilities critically examines the breadth of research on this complex and controversial topic, with the principal aim of helping the reader to understand where sex differences are found – and where they are not. Since the publication of the third edition, there have been many exciting and illuminating developments in our understanding of cognitive sex differences. Modern neuroscience has transformed our understanding of the mind and behavior in general, but particularly the way we think about cognitive sex differences. But neuroscience is still in its infancy and has often been misused to justify sex role stereotypes. There has also been the publication of many exaggerated and unreplicated claims regarding cognitive sex differences. Consequently, throughout the book there is recognition of the critical importance of good research; an amiable skepticism of the nature and strength of evidence behind any claim of sex difference; an appreciation of the complexity of the questions about cognitive sex differences; and the ability to see multiple sides of an issues, while also realizing that some claims are well-reasoned and supported by data and others are politicized pseudoscience. The author endeavors to present and interpret all the relevant data fairly, and in the process reveals how there are strong data for many different views. The book explores sex differences from many angles and in many settings, including the effect of different abilities and levels of education on sex differences, pre-existing beliefs or stereotypes, culture, and hormones. Sex differences in the brain are explored along with the stern caveat to "mind the gap" between brain structures and behaviors. Readers should come away with a new understanding of the way nature and nurture work together to make us unique individuals while also creating similarities and differences that are often (but not always) tied to our being female and male. Sex Differences in Cognitive Abilities, Fourth Edition, can be used as a textbook or reference in a range of courses and will inspire the next generation of researchers. Halpern engages readers in the big societal questions that are inherent in the controversial topic of whether, when , and how much males and females differ psychologically. It should be required reading for parents, teachers, and policy makers who want to know about the ways in which males and females are different and similar.
