“Will the future confront us with human GMOs? Greely provocatively declares yes, and, while clearly explaining the science, spells out the ethical, political, and practical ramifications.”—Paul Berg, Nobel Laureate and recipient of the National Medal of Science Within twenty, maybe forty, years most people in developed countries will stop having sex for the purpose of reproduction. Instead, prospective parents will be told as much as they wish to know about the genetic makeup of dozens of embryos, and they will pick one or two for implantation, gestation, and birth. And it will be safe, lawful, and free. In this work of prophetic scholarship, Henry T. Greely explains the revolutionary biological technologies that make this future a seeming inevitability and sets out the deep ethical and legal challenges humanity faces as a result. “Readers looking for a more in-depth analysis of human genome modifications and reproductive technologies and their legal and ethical implications should strongly consider picking up Greely’s The End of Sex and the Future of Human Reproduction... [It has] the potential to empower readers to make informed decisions about the implementation of advancements in genetics technologies.” —Dov Greenbaum, Science “[Greely] provides an extraordinarily sophisticated analysis of the practical, political, legal, and ethical implications of the new world of human reproduction. His book is a model of highly informed, rigorous, thought-provoking speculation about an immensely important topic.” —Glenn C. Altschuler, Psychology Today

A primatologist explores the mystery of the origins of human reproduction, explaining that understanding the evolutionary past can provide insight into what worked, what didn't, and what it all means for the future of mankind.

In the tradition of Silent Spring and The Sixth Extinction, an urgent, meticulously researched, and groundbreaking book about the ways in which chemicals in the modern environment are changing—and endangering—human sexuality and fertility on the grandest scale, from renowned epidemiologist Shanna Swan. In 2017, author Shanna Swan and her team of researchers completed a major study. They found that over the past four decades, sperm levels among men in Western countries have dropped by more than 50 percent. They came to this conclusion after examining 185 studies involving close to 45,000 healthy men. The result sent shockwaves around the globe—but the story didn’t end there. It turns out our sexual development is changing in broader ways, for both men and women and even other species, and that the modern world is on pace to become an infertile one. How and why could this happen? What is hijacking our fertility and our health? Count Down unpacks these questions, revealing what Swan and other researchers have learned about how both lifestyle and chemical exposures are affecting our fertility, sexual development—potentially including the increase in gender fluidity—and general health as a species. Engagingly explaining the science and repercussions of these worldwide threats and providing simple and practical guidelines for effectively avoiding chemical goods (from water bottles to shaving cream) both as individuals and societies, Count Down is at once an urgent wake-up call, an illuminating read, and a vital tool for the protection of our future.

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.

Extensive social science research, particularly by anthropologists, has explored women?s reproductive lives, their use of reproductive technologies, and their experiences as mothers and nurturers of children. Meanwhile, few if any volumes have explored men?s reproductive concerns or contributions to women?s reproductive health: Men are clearly viewed as the?second sex? in reproduction. This volume argues that the marginalization of men is an oversight of considerable proportions, and thereby seeks to break the silence surrounding men?s thoughts, experiences, and feelings about their reproductive lives. It sheds new light on male reproduction from a cross-cultural, global perspective, focusing not only upon men in Europe and America but also those in the Middle East, Asia, and Latin America. Both heterosexual and homosexual, married and unmarried men are featured in this volume, which assesses concerns ranging from masculinity and sexuality to childbirth and fatherhood. Thus, men are brought back into the equation, as reproductive partners, progenitors, fathers, nurturers, and decision-makers.

Through nostalgic idealizations of motherhood, family, and the home, influential leaders in early twentieth-century America constructed and legitimated a range of reforms that promoted human reproduction. Their pronatalism emerged from a modernist conviction that reproduction and population could be regulated. European countries sought to regulate or encourage reproduction through legislation; America, by contrast, fostered ideological and cultural ideas of pronatalism through what Laura Lovett calls "nostalgic modernism," which romanticized agrarianism and promoted scientific racism and eugenics. Lovett looks closely at the ideologies of five influential American figures: Mary Lease's maternalist agenda, Florence Sherbon's eugenic "fitter families" campaign, George Maxwell's "homecroft" movement of land reclamation and home building, Theodore Roosevelt's campaign for conservation and country life, and Edward Ross's sociological theory of race suicide and social control. Demonstrating the historical circumstances that linked agrarianism, racism, and pronatalism, Lovett shows how reproductive conformity was manufactured, how it was promoted, and why it was coercive. In addition to contributing to scholarship in American history, gender studies, rural studies, and environmental history, Lovett's study sheds light on the rhetoric of "family values" that has regained currency in recent years.
