Book excerpt: Where do we come from? Where do animals come from? For thousands of years we really had no clue how living things were created -- great thinkers like Aristotle and Plato had attempted to explain what became known as the problem of 'generation', but neither really had the tools or the insight to solve the mystery. The result was a wealth of weird and wonderful ideas about the components necessary to create new life -- blood, 'vapours', strange pulses in the air. Nor did people make intuitive leaps that now seem self-evident: it was widely accepted that animals could breed different species, for example; the notion that two sheep can only make another sheep is a surprisingly modern idea.But all this confusion changed in a flurry of discovery in the mid-seventeenth century. In just a decade, a group of young scientists in Europe, all known to each other and in competition with each other, established the existence first of the human egg and then of the human sperm. At last, the building blocks were in place -- although, in one of the great ironies of science, it would be another 150 years before someone worked out how fertilisation actually took place.Focusing on the personalities and rivalries of this extraordinary period, Matthew Cobb has shed new light not just on an under-reported story of science but on our very nature -- what makes us, and how little we still know about one of the greatest miracles of Nature.

Download or read book Freezing Fertility written by Lucy van de Wiel and published by NYU Press. This book was released on 2020-12-15 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Welcomed as liberation and dismissed as exploitation, egg freezing (oocyte cryopreservation) has rapidly become one of the most widely-discussed and influential new reproductive technologies of this century. In Freezing Fertility, Lucy van de Wiel takes us inside the world of fertility preservation—with its egg freezing parties, contested age limits, proactive anticipations and equity investments—and shows how the popularization of egg freezing has profound consequences for the way in which female fertility and reproductive aging are understood, commercialized and politicized. Beyond an individual reproductive choice for people who may want to have children later in life, Freezing Fertility explores how the rise of egg freezing also reveals broader cultural, political and economic negotiations about reproductive politics, gender inequities, age normativities and the financialization of healthcare. Van de Wiel investigates these issues by analyzing a wide range of sources—varying from sparkly online platforms to heart-breaking court cases and intimate autobiographical accounts—that are emblematic of each stage of the egg freezing procedure. By following the egg’s journey, Freezing Fertility examines how contemporary egg freezing practices both reflect broader social, regulatory and economic power asymmetries and repoliticize fertility and aging in ways that affect the public at large. In doing so, the book explores how the possibility of egg freezing shifts our relation to the beginning and end of life.
Download or read book Sperm Wars written by Robin Baker and published by Basic Books. This book was released on 2006-01-03 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: This classic work on the rules of sex -- updated for a new generation -- is still as provocative as the day it was published, providing simple explanations for any and all questions about what happens in the bedroom. Sex isn't as complicated as we make it. In Sperm Wars, evolutionary biologist Robin Baker argues that every question about human sexuality can be explained by one simple thing: sperm warfare. In the interest of promoting competition between sperm to fertilize the same egg, evolution has built men to conquer and monopolize women while women are built to seek the best genetic input on offer from potential sexual partners. Baker reveals, through a series of provocative fictional scene, the far-reaching implications of sperm competition. 10% of children are not fathered by their "fathers;" over 99% of a man's sperm exists simply to fight off all other men's sperm; and a woman is far more likely to conceive through a casual fling than through sex with her regular partner. From infidelity, to homosexuality, to the female orgasm, Sperm Wars turns on every light in the bedroom. Now with new material reflecting the latest research on sperm warfare, this milestone of popular science will still surprise, entertain, and even shock.
Download or read book Where Willy Went written by Nicholas Allan and published by Knopf Books for Young Readers. This book was released on 2011-11-30 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Never before have the facts of life been presented in such an accessible—or novel—way. Our hero is Willy, a little sperm who lives inside Mr. Browne with 300 million friends. Every day Willy practices for the Great Swimming Race. And when the day arrives, he swims faster than his 300 million friends to win the prize—a marvelous egg. Then something wonderful happens, and eventually Mr. and Mrs. Browne have a baby girl who has the same winning smile as Willy and who grows up to be a great swimmer. Hilariously funny, warm, and endearing, this is a picture book that appeals on different levels to both children and grown-ups. “Fresh, original, and imaginative. . . . Allan’s achievement is in couching fascinating facts within the construct of a gentle, direct narrative. A little knowledge is a wonderful thing, and as the rest of the facts of life fall into place, Allan’s readers will look back on this book with a mixture of fondness and wry amusement.” —The Guardian (UK)

Available in PDF, EPUB and Kindle. Book excerpt: This is an open access title available under the terms of a CC BY-NC-ND 4.0 International license. It is free to read at Oxford Scholarship Online and offered as a free PDF download from OUP and selected open access locations. Each year, tens of thousands of children are conceived with donated gametes (sperm or eggs). By some estimates, there are over one million donor-conceived people in the United States and, of course, many more the world over. Some know they are donor-conceived. Some do not. Some know the identity of their donors. Others never will. Questions about what donor-conceived people should know about their genetic progenitors are hugely significant for literally millions of people, including donor-conceived people, their parents, and donors. But the practice of gamete donation also provides a vivid occasion for thinking about questions that matter to everyone. What is the value of knowing who your genetic progenitors are? How are our identities bound up with knowing where we come from? What obligations do parents have to their children? And what makes someone a parent in the first place? In Conceiving People: Identity, Genetics and Gamete Donation, Daniel Groll argues that people who plan to create a child with donated gametes should choose a donor whose identity will be made available to the resulting child. This is not, Groll argues, because having genetic knowledge is fundamentally important. Rather, it is because donor-conceived people are likely to develop a significant interest in having genetic knowledge and parents must help satisfy their children's significant interests. In other words, because a donor-conceived person is likely to care about having genetic knowledge, their parents should care too.

Download or read book The Ovary of Eve written by Clara Pinto-Correia and published by University of Chicago Press. This book was released on 2007-12-01 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ovary of Eve is a rich and often hilarious account of seventeenth- and eighteenth-century efforts to understand conception. In these early years of the Scientific Revolution, the most intelligent men and women of the day struggled to come to terms with the origins of new life, and one theory—preformation—sparked an intensely heated debate that continued for over a hundred years. Clara Pinto-Correia traces the history of this much maligned theory through the cultural capitals of Europe. "The most wonderfully eye-opening, or imagination-opening book, as amusing as it is instructive."—Mary Warnock, London Observer "[A] fascinating and often humorous study of a reproductive theory that flourished from the mid-17th century to the mid-18th century."—Nina C. Ayoub, Chronicle of Higher Education "More than just a good story, The Ovary of Eve is an object lesson about the history of science: Don't trust it. . . . Pinto-Correia says she wants to tell the story of history's losers. In doing so, she makes defeat sound more appealing than victory."—Emily Eakin, Nation. "A sparkling history of preformation as it once affected every facet of European culture."—Robert Taylor, Boston Globe

Download or read book Brown Bodies White Babies written by Laura Harrison and published by NYU Press. This book was released on 2016-09-20 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focuses on the practice of cross-racial gestational surrogacy, in which a woman--through in-vitro fertilization using the sperm and egg of intended parents or donors--carries a pregnancy for intended parents of a different race. Concentrating on the racial differences between parents and surrogates, Harrison is interested in how reproductive technologies intersect with race, particularly when brown bodies produce white babies. She provides an interdisciplinary analysis that includes legal cases of contested surrogacy, historical examples of surrogacy as a form of racialized reproductive labor, the role of genetics in the assisted reproduction industry, and the recent turn toward reproductive tourism. --From publisher description.
Download or read book The End of Sex and the Future of Human Reproduction written by Henry T. Greely and published by Harvard University Press. This book was released on 2016-05-30 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: “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
