Book Synopsis Between XX and XY by : Gerald Callahan

Download or read book Between XX and XY written by Gerald Callahan. This book was released on 2009-07-01. Available in PDF, EPUB and Kindle. Book excerpt: Providing a fascinating look at the science of sex and what makes people male or female, this book explains dozens of intersex conditions—such as hermaphroditism, Klinefelter syndrome, and androgen insensitivity syndrome—and includes personal interviews with people living with these conditions telling their surprising and often heart-wrenching stories. Even doctors and scientists are not entirely sure if external genitalia, internal sex organs, chromosomes, DNA, environment, or some combination define a person's sex, but this examination shows that sex is not an either-or proposition: not girl/boy, XX/XY—there are babies born XYY, XXX, or with any dozen or more known variations in the X or Y chromosomes. The history and the current treatment for intersex conditions as well as the options that are available today for the ambiguous child are covered in this captivating account that truly shows what it means to be human.

Download or read book Exploring the Biological Contributions to Human Health written by Institute of Medicine. This book was released on 2001-07-02. Available in PDF, EPUB and Kindle. 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.

Download or read book The Better Half written by Dr. Sharon Moalem, MD, PhD. This book was released on 2020-04-07. Available in PDF, EPUB and Kindle. Book excerpt: A Guardian Book of the Week Longlisted for the PEN / E. O. Wilson Literary Science Writing Award An award-winning physician and scientist makes the game-changing case that genetic females are stronger than males at every stage of life Here are some facts: Women live longer than men. They have stronger immune systems. They're better at fighting cancer and surviving famine, and even see the world in a wider variety of colors. They are simply stronger than men at every stage of life. Why is this? And why are we taught the opposite? To find out, Dr. Sharon Moalem drew on his own medical experiences - treating premature babies in the neonatal intensive care unit; recruiting the elderly for neurogenetic studies; tending to HIV-positive orphans in Thailand - and tried to understand why in every instance men were consistently less likely to thrive. The answer, he discovered, lies in our genetics: two X chromosomes offer a powerful survival advantage. With clear, captivating prose that weaves together eye-opening research, case studies, diverse examples ranging from the behavior of honeybees to American pioneers, as well as experiences from his personal life and his own patients, Moalem explains why genetic females triumph over males when it comes to resiliency, intellect, stamina, immunity and much more. He also calls for a reconsideration of our male-centric, one-size-fits-all view of medical studies and even how we prescribe medications - a view that still sees women through the lens of men. Revolutionary and yet utterly convincing, The Better Half will make you see humanity and the survival of our species anew.

Book Synopsis Sex Itself by : Sarah S. Richardson

Download or read book Sex Itself written by Sarah S. Richardson. This book was released on 2013-12-13. Available in PDF, EPUB and Kindle. Book excerpt: Human genomes are 99.9 percent identical—with one prominent exception. Instead of a matching pair of X chromosomes, men carry a single X, coupled with a tiny chromosome called the Y. Tracking the emergence of a new and distinctive way of thinking about sex represented by the unalterable, simple, and visually compelling binary of the X and Y chromosomes, Sex Itself examines the interaction between cultural gender norms and genetic theories of sex from the beginning of the twentieth century to the present, postgenomic age. Using methods from history, philosophy, and gender studies of science, Sarah S. Richardson uncovers how gender has helped to shape the research practices, questions asked, theories and models, and descriptive language used in sex chromosome research. From the earliest theories of chromosomal sex determination, to the mid-century hypothesis of the aggressive XYY supermale, to the debate about Y chromosome degeneration, to the recent claim that male and female genomes are more different than those of humans and chimpanzees, Richardson shows how cultural gender conceptions influence the genetic science of sex. Richardson shows how sexual science of the past continues to resonate, in ways both subtle and explicit, in contemporary research on the genetics of sex and gender. With the completion of the Human Genome Project, genes and chromosomes are moving to the center of the biology of sex. Sex Itself offers a compelling argument for the importance of ongoing critical dialogue on how cultural conceptions of gender operate within the science of sex.
