Book Synopsis Egg and Sperm Race by : Matthew Cobb
Download or read book Egg and Sperm Race written by Matthew Cobb and published by . This book was released on 2006 with total page 362 pages. Available in PDF, EPUB and Kindle. 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.

Book Synopsis Freezing Fertility by : Lucy van de Wiel
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.

Book Synopsis Sperm Competition in Humans by : Todd K. Shackelford
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.

Harris and Emberley established themselves as the purveyors of reader-friendly, straightforward information on human sexuality for readers as young as seven. Here they successfully tackle the big questions . . . for even younger kids." – The Horn Book (starred review) Young children are curious about almost everything, especially their bodies. And young children are not afraid to ask questions. What makes me a girl? What makes me a boy? Why are some parts of girls' and boys' bodies the same and why are some parts different? How was I made? Where do babies come from? Is it true that a stork brings babies to mommies and daddies? IT'S NOT THE STORK! helps answer these endless and perfectly normal questions that preschool, kindergarten, and early elementary school children ask about how they began. Through lively, comfortable language and sensitive, engaging artwork, Robie H. Harris and Michael Emberley address readers in a reassuring way, mindful of a child's healthy desire for straightforward information. Two irresistible cartoon characters, a curious bird and a squeamish bee, provide comic relief and give voice to the full range of emotions and reactions children may experience while learning about their amazing bodies. Vetted and approved by science, health, and child development experts, the information is up-to-date, age-appropriate, and scientifically accurate, and always aimed at helping kids feel proud, knowledgeable, and comfortable about their own bodies, about how they were born, and about the family they are part of.
