Available in PDF, EPUB and Kindle. Book excerpt: A groundbreaking twentieth-century history of transgender children With transgender rights front and center in American politics, media, and culture, the pervasive myth still exists that today’s transgender children are a brand new generation—pioneers in a field of new obstacles and hurdles. Histories of the Transgender Child shatters this myth, uncovering a previously unknown twentieth-century history when transgender children not only existed but preexisted the term transgender and its predecessors, playing a central role in the medicalization of trans people, and all sex and gender. Beginning with the early 1900s when children with “ambiguous” sex first sought medical attention, to the 1930s when transgender people began to seek out doctors involved in altering children’s sex, to the invention of the category gender, and finally the 1960s and ’70s when, as the field institutionalized, transgender children began to take hormones, change their names, and even access gender confirmation, Julian Gill-Peterson reconstructs the medicalization and racialization of children’s bodies. Throughout, they foreground the racial history of medicine that excludes black and trans of color children through the concept of gender’s plasticity, placing race at the center of their analysis and at the center of transgender studies. Until now, little has been known about early transgender history and life and its relevance to children. Using a wealth of archival research from hospitals and clinics, including incredible personal letters from children to doctors, as well as scientific and medical literature, this book reaches back to the first half of the twentieth century—a time when the category transgender was not available but surely existed, in the lives of children and parents.

Book excerpt: Now updated with groundbreaking research, this award-winning classic examines the construction of sexual identity in biology, society, and history. Why do some people prefer heterosexual love while others fancy the same sex? Is sexual identity biologically determined or a product of convention? In this brilliant and provocative book, the acclaimed author of Myths of Gender argues that even the most fundamental knowledge about sex is shaped by the culture in which scientific knowledge is produced. Drawing on astonishing real-life cases and a probing analysis of centuries of scientific research, Fausto-Sterling demonstrates how scientists have historically politicized the body. In lively and impassioned prose, she breaks down three key dualisms -- sex/gender, nature/nurture, and real/constructed -- and asserts that individuals born as mixtures of male and female exist as one of five natural human variants and, as such, should not be forced to compromise their differences to fit a flawed societal definition of normality.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The announcement that we had decoded the human genome in 2000 ushered in a new and unique era in biomedical research and clinical medicine. This Third Edition of Principles of Gender-Specific Medicine focuses, as in the past two editions, on the essentials of sexual dimorphism in human physiology and pathophysiology, but emphasizes the latest information about molecular biology and genomic science in a variety of disciplines. Thus, this edition is a departure from the previous two; the editor solicited individual manuscripts from innovative scientists in a variety of fields rather than the traditional arrangement of sections devoted to the various subspecialties of medicine edited by section chiefs. Wherever it was available, these authors incorporated the latest information about the impact of the genome and the elements that modify its expression on human physiology and illness. All chapters progress translationally from basic science to the clinical applications of gender-specific therapy and suggest the most important topics for future investigation. This book is essential reading for all biomedical investigators and medical educators involved in gender-specific medicine. It will also be useful for primary care practitioners who need information about the importance of sex and gender in the prevention, diagnosis and treatment of illness.

This book was released on 2003-03-13 with total page 815 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first comprehensive synthesis on development and evolution: it applies to all aspects of development, at all levels of organization and in all organisms, taking advantage of modern findings on behavior, genetics, endocrinology, molecular biology, evolutionary theory and phylogenetics to show the connections between developmental mechanisms and evolutionary change. This book solves key problems that have impeded a definitive synthesis in the past. It uses new concepts and specific examples to show how to relate environmentally sensitive development to the genetic theory of adaptive evolution and to explain major patterns of change. In this book development includes not only embryology and the ontogeny of morphology, sometimes portrayed inadequately as governed by "regulatory genes," but also behavioral development and physiological adaptation, where plasticity is mediated by genetically complex mechanisms like hormones and learning. The book shows how the universal qualities of phenotypes--modular organization and plasticity--facilitate both integration and change. Here you will learn why it is wrong to describe organisms as genetically programmed; why environmental induction is likely to be more important in evolution than random mutation; and why it is crucial to consider both selection and developmental mechanism in explanations of adaptive evolution. This book satisfies the need for a truly general book on development, plasticity and evolution that applies to living organisms in all of their life stages and environments. Using an immense compendium of examples on many kinds of organisms, from viruses and bacteria to higher plants and animals, it shows how the phenotype is reorganized during evolution to produce novelties, and how alternative phenotypes occupy a pivotal role as a phase of evolution that fosters diversification and speeds change. The arguments of this book call for a new view of the major themes of evolutionary biology, as shown in chapters on gradualism, homology, environmental induction, speciation, radiation, macroevolution, punctuation, and the maintenance of sex. No other treatment of development and evolution since Darwin's offers such a comprehensive and critical discussion of the relevant issues. Developmental Plasticity and Evolution is designed for biologists interested in the development and evolution of behavior, life-history patterns, ecology, physiology, morphology and speciation. It will also appeal to evolutionary paleontologists, anthropologists, psychologists, and teachers of general biology.

Book excerpt: THE BRILLIANT AND HUGELY INFLUENTIAL BOOK BY THE WINNER OF THE 2017 ROYAL SOCIETY INSIGHT INVESTMENT SCIENCE BOOKS PRIZE 'Fun, droll yet deeply serious.' New Scientist 'A brilliant feminist critic of the neurosciences ... Read her, enjoy and learn.' Hilary Rose, THES 'A witty and meticulously researched exposé of the sloppy studies that pass for scientific evidence in so many of today's bestselling books on sex differences.' Carol Tavris, TLS Gender inequalities are increasingly defended by citing hard-wired differences between the male and female brain. That's why, we're told, there are so few women in science, so few men in the laundry room – different brains are just suited to different things. With sparkling wit and humour, Cordelia Fine attacks this 'neurosexism', revealing the mind's remarkable plasticity, the substantial influence of culture on identity, and the malleability of what we consider to be 'hardwired' difference. This modern classic shows the surprising extent to which boys and girls, men and women are made – not born.

Available in PDF, EPUB and Kindle. Book excerpt: Countersexual Manifesto is an outrageous yet rigorous work of trans theory, a performative literary text, and an insistent call to action. Seeking to overthrow all constraints on what can be done with and to the body, Paul B. Preciado offers a provocative challenge to even the most radical claims about gender, sexuality, and desire. Preciado lays out mock constitutional principles for a countersexual revolution that will recognize genitalia as technological objects and offers step-by-step illustrated instructions for dismantling the heterocentric social contract. He calls theorists such as Derrida, Foucault, Butler, and Haraway to task for not going nearly far enough in their attempts to deconstruct the naturalization of normative identities and behaviors. Preciado’s claim that the dildo precedes the penis—that artifice, not nature, comes first in the history of sexuality—forms the basis of his demand for new practices of sexual emancipation. He calls for a world of sexual plasticity and fabrication, of bio-printers and “dildonics,” and he invokes countersexuality’s roots in the history of sex toys, pornography, and drag in order to rupture the supposedly biological foundations of the heterocentric regime. His claims are extreme, but supported through meticulous readings of philosophy and theory, as well as popular culture. The Manifesto is now available in English translation for its twentieth anniversary, with a new introduction by Preciado. Countersexual Manifesto will disrupt feminism and queer theory and scandalize us all with its hyperbolic but deadly serious defiance of everything we’ve been told about sex.

Available in PDF, EPUB and Kindle. Book excerpt: The brains of males and females, men and women, are different, that is a fact. What is debated is how different and how important are those differences. Sex differences in the brain are determined by genetics, hormones, and experience, which in humans includes culture, society, and parental and peer expectations. The importance of nonbiological variables to sex differences in humans is paramount, making it difficult if not impossible to parse out those contributions that are truly biological. The study of animals provides us the opportunity to understand the magnitude and scope of biologically based sex differences in the brain, and understanding the cellular mechanisms provides us insight into novel sources of brain plasticity. Many sex differences are established during a developmental sensitive window by differences in the hormonal milieu of males versus females. The neonatal testis produces large amounts of testosterone which gains access to the brain and is further metabolized into active androgens and estrogens which modify brain development. Major parameters that are influenced by hormones include neurogenesis, cell death, neurochemical phenotype, axonal and dendritic growth, and synaptogenesis. Variance in these parameters results in sex differences in the size of particular brain regions, the projections between brain regions, and the number and type of synapses within particular brain regions. The cellular mechanisms are both region and endpoint specific and invoke many surprising systems such as prostaglandins, endocannabinoids, and cell death proteins. Epigenetic modifications to the genome both establish and maintain sex differences in the brain and behavior. By understanding when, why, and how sex differences in the brain are established, we may also learn the source of strong gender biases in the relative risk and severity of numerous neurological diseases and disorders of mental health. Boys are much more likely to be diagnosed with autism spectrum or attention and hyperactivity disorders, as well as speech and language deficits, compared to girls. By contrast, women are more likely to suffer from affective disorders, such as depression, anxiety, compulsion, and eating disorders and more likely to experience autoimmune and neurodegenerative disorders. Schizophrenia with an early onset is more common in males but a late-onset version is markedly more frequent in females. Male biased disorders have origins in development while female biased disorders are almost exclusively post-puberty. This remarkable shift in disease risk demands our attention. Novel insights into the biological origins of disease are also gained by comparing and contrasting the same processes in different sexes.

Available in PDF, EPUB and Kindle. Book excerpt: Is love “blind” when it comes to gender? For women, it just might be. This unsettling and original book offers a radical new understanding of the context-dependent nature of female sexuality. Lisa M. Diamond argues that for some women, love and desire are not rigidly heterosexual or homosexual but fluid, changing as women move through the stages of life, various social groups, and, most important, different love relationships.This perspective clashes with traditional views of sexual orientation as a stable and fixed trait. But that view is based on research conducted almost entirely on men. Diamond is the first to study a large group of women over time. She has tracked one hundred women for more than ten years as they have emerged from adolescence into adulthood. She summarizes their experiences and reviews research ranging from the psychology of love to the biology of sex differences. Sexual Fluidity offers moving first-person accounts of women falling in and out of love with men or women at different times in their lives. For some, gender becomes irrelevant: “I fall in love with the person, not the gender,” say some respondents.Sexual Fluidity offers a new understanding of women’s sexuality—and of the central importance of love.

Book excerpt: A breakthrough work in neuroscience—and an incisive corrective to a long history of damaging pseudoscience—that finally debunks the myth that there is a hardwired distinction between male and female brains We live in a gendered world, where we are ceaselessly bombarded by messages about sex and gender. On a daily basis, we face deeply ingrained beliefs that sex determines our skills and preferences, from toys and colors to career choice and salaries. But what does this constant gendering mean for our thoughts, decisions and behavior? And what does it mean for our brains? Drawing on her work as a professor of cognitive neuroimaging, Gina Rippon unpacks the stereotypes that surround us from our earliest moments and shows how these messages mold our ideas of ourselved and even shape our brains. By exploring new, cutting-edge neuroscience, Rippon urges us to move beyond a binary view of the brain and to see instead this complex organ as highly individualized, profoundly adaptable and full of unbounded potential. Rigorous, timely and liberating, Gender and Our Brains has huge implications for women and men, for parents and children, and for how we identify ourselves.

Available in PDF, EPUB and Kindle. Book excerpt: When there is uncertainty about the gender identity or social gender role of an individual, determining exactly who the opposite sex is can be a complicated question for both the transgender person and for those who seek to relate to her. Written in both an enlightened and a reader friendly style interspersed with vignettes, When the Opposite Sex Isn’t offers a combination of insights and common sense understanding of the diversity of the human condition together with concepts of gender and sexuality that expand the horizons of any mental health professional, regardless of the clinical focus of his or her work. Samons challenges concepts once taken for granted, thus providing stimulus for creative thinking which many lay readers will also find interesting and entertaining, whether or not they are (thus far) acquainted with a transgender person.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sex determination, differentiation and gamete maturation are well organised molecular events in vertebrates. In vertebrates, sex determination and differentiation are two important events in the development of gonads (testis or ovary). Sex determination is the genetic (sex chromosomes) or environmental process by which the sex (male or female) of an individual is established. During embryonic development, primordial germ cells migrate from the site of origin to the gonadal primordia where they differentiate along with somatic cells and finally form the indifferent/bipotential gonads. Depending on the action of various factors the bipotential gonads give rise to either testis or ovaries. In most vertebrates, excluding fishes and some amphibians, the event of sex determination is controlled genetically and later the progression of gonadal development is controlled by hormones and other factors. Interestingly, these processes in fishes are controlled not only genetically but also through hormones or environmental factors. These characteristics make fish the champions of sex reversal and serve as excellent animal models to precisely understand sexual development. The next interesting aspect is meiotic maturation which is essentially mediated by gonadotropins and progesterone metabolites to trigger final gamete maturation in fishes which is different from mammals. The novel aspects pertaining to gamete maturation has been studied in great detail in fish which depicts precise regulatory events of gamete maturation.
