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 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.

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)
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 Competition in Humans written by Todd K. Shackelford and published by Springer. This book was released on 2010-10-29 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In species with internal fertilization, sperm competition occurs when the sperm of two or more males simultaneously occupy the reproductive tract of a female and compete to fertilize an egg (Parker, 1970). A large body of empirical research has demonstrated that, as predicted by sperm competition theory, males and females in many species possess anatomical, behavioral, and physiological adaptations that have evolved to deal with the adaptive challenges associated with sperm competition. Moreover, in recent years, evolutionary biologists and psychologists have begun to examine the extent to which sperm competition may have been an important selective pressure during human evolution. Some research has suggested that male humans, like males of many bird, insect, and rodent species, might be able to adjust the number of sperm they inseminate according to the risk of sperm competition. Other research has examined whether such responses might be accompanied by psychological changes that motivate human males to pursue copulations when the risk of sperm competition is high. Furthermore, there is research suggesting that aspects of human penile anatomy might function to enhance success in sperm competition. Much of this work has been controversial; some of the findings have been disputed and others have been greeted with skepticism. However, the idea that some aspects of human psychology and behavior might best be understood as adaptations to sperm competition remains intriguing and, in certain cases, very persuasive.

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 Life s Greatest Secret written by Matthew Cobb and published by Hachette UK. This book was released on 2015-07-07 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Everyone has heard of the story of DNA as the story of Watson and Crick and Rosalind Franklin, but knowing the structure of DNA was only a part of a greater struggle to understand life's secrets. Life's Greatest Secret is the story of the discovery and cracking of the genetic code, the thing that ultimately enables a spiraling molecule to give rise to the life that exists all around us. This great scientific breakthrough has had farreaching consequences for how we understand ourselves and our place in the natural world, and for how we might take control of our (and life's) future. Life's Greatest Secret mixes remarkable insights, theoretical dead-ends, and ingenious experiments with the swift pace of a thriller. From New York to Paris, Cambridge, Massachusetts, to Cambridge, England, and London to Moscow, the greatest discovery of twentieth-century biology was truly a global feat. Biologist and historian of science Matthew Cobb gives the full and rich account of the cooperation and competition between the eccentric characters -- mathematicians, physicists, information theorists, and biologists -- who contributed to this revolutionary new science. And, while every new discovery was a leap forward for science, Cobb shows how every new answer inevitably led to new questions that were at least as difficult to answer: just ask anyone who had hoped that the successful completion of the Human Genome Project was going to truly yield the book of life, or that a better understanding of epigenetics or "junk DNA" was going to be the final piece of the puzzle. But the setbacks and unexpected discoveries are what make the science exciting, and it is Matthew Cobb's telling that makes them worth reading. This is a riveting story of humans exploring what it is that makes us human and how the world works, and it is essential reading for anyone who'd like to explore those questions for themselves.

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
