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 Wonderful Sperm written by Alan Smithie and published by AuthorHouse. This book was released on 2009-07-01 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: I remember a report some time ago extolling the health benefits of the vitamins found in sperm, with the advice that in preparation for having a healthy and intelligent baby, for some months before becoming pregnant a woman should swallow her partner's sperm. You can rest assured this report was compiled by a team of men. This has nothing whatsoever to do with the fact I set out to write a book entitled "49," a humorously light-hearted fly-on-the-wall look at my life from the day before my forty-ninth birthday to the day I hit fifty. A story of how I was coping with being too old for a mid-life crisis, counting the days tick down until the inevitable half-century. Should I be wearing socks with sandals; when would I start to enjoy pastimes that involved either binoculars, a fishing rod, making boats out of used matchsticks, a tandem bicycle or Morris dancing? Was I developing man-breasts, and more importantly, would the next woman I meet have bingo-wings? What pre-fifty pastimes would I be consigning to the dusty bin of life - wearing Ramones T-shirts and ogling young girls; my T-shirt definitely had to go. Maybe I wouldn't even make it to the end of the book; instead I'd meet my end running the Snowdonia Marathon. As it was I did make it to the end. Having spent a year writing "49" and many months trying to get a publishing deal without success, I started to write a blog. I pretty soon realised the missing ingredient - sex: sex sells. Post a good title and you have a success; mention anal sex and you have a best-seller. Without a second thought I changed the book title to "Sperm, Wonderful Sperm!" and quickly contacted an online print-on-demand publisher. This is the result...

Download or read book The Great Sperm Whale written by Richard Ellis and published by University Press of Kansas. This book was released on 2011-04-06 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past several decades, Richard Ellis has produced a remarkable body of work that has been called "magnificent" (Washington Post Book World), "masterful" (Scientific American), "magical" (Men's Journal), and a "dazzling tour de force" (Christian Science Monitor). Ellis's new book-a fascinating tour through the world of the sperm whale-will surely inspire more such praise for the author heralded by Publisher Weekly as "America's foremost writer on marine research." Written with Ellis's deep knowledge and trademark passion, verve, and wit-and illustrated with a wide array of images including his own signature artwork-his study covers the full spectrum of the sperm whale's existence from its prehistoric past to its current endangered existence. Ellis, as no one else can, illuminates the iconic impact of Physeter macrocephalus ("big-headed blower") on our history, environment, and culture, with a substantial nod to Herman Melville and Moby-Dick, the great novel that put the sperm whale (and whaling) on the literary map. Ranging far and wide, Ellis covers the sperm whale's evolution, ecology, biology, anatomy, behavior, social organization, intelligence, communications, migrations, diet, and breeding. He also devotes considerable space to the whale's hunting prowess, including its clashes with the giant squid, and to the history of the whaling industry that decimated its numbers during the last two centuries. He even includes a story about a beached juvenile he helped rescue, an event that provided scientists with one of their first opportunities to observe a sperm whale in the water and up close. Offering a rich tapestry for anyone with an interest in the marvels of ocean life, Ellis's book provides an indispensable guide to the life and times of one of the planet's most intelligent, elusive, and endangered species.

Download or read book Sperm Whales written by Hal Whitehead and published by University of Chicago Press. This book was released on 2003-08-15 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Famed in story as "the great leviathans," sperm whales are truly creatures of extremes. Giants among all whales, they also have the largest brains of any creature on Earth. Males can reach a length of sixty-two feet and can weigh upwards of fifty tons. With this book, Hal Whitehead gives us a clearer picture of the ecology and social life of sperm whales than we have ever had before. Based on almost two decades of field research, Whitehead describes their biology, behavior, and habitat; how they organize their societies; and how their complex lifestyles may have evolved in this unique environment. Among the many fascinating topics he explores is the crucial role that culture plays in the life of the sperm whale, and he traces the consequences of this argument for both evolution and conservation. Finally, drawing on these findings, Whitehead builds a general model of how the ocean environment influences social behavior and cultural evolution among mammals as well as other animals. The definitive portrait of a provocative creature, Sperm Whales will interest animal behaviorists, conservationists, ecologists, and evolutionary biologists as well as marine mammalogists.

Book excerpt: As outspoken in his day as Richard Dawkins or Christopher Hitchens are today, American freethinker and author ROBERT GREEN INGERSOLL (1833-1899) was a notorious radical whose uncompromising views on religion and slavery (they were bad, in his opinion), women's suffrage (a good idea, he believed), and other contentious matters of his era made him a wildly popular orator and critic of 19th-century American culture and public life. As a speaker dedicated to expanding intellectual horizons and celebrating the value of skepticism, Ingersoll spoke frequently on such topics as atheism, freedom from the pressures of conformity, and the lives of philosophers who espoused such concepts. This collection of his most famous speeches includes the lectures: [ "The Gods" (1872) [ "Humboldt" (1869) [ "Thomas Paine" (1870) [ "Individuality" (1873) [ "Heretics and Heresies" (1874)
Download or read book Sperm Soldier written by Evets Ornum and published by Page Publishing Inc. This book was released on 2020-05-01 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: After the first great war, three men in America, concerned the millions of fatherless children would be raised feminine, bred a supersoldier. Believing there is a hero gene, these men, after the conception of artificial insemination, built a complex breeding system. With the unknowing help of the government, they devised a plan to grow their hero soldiers. Extracting sperm from combat veterans who served above and beyond and tricking any widow of a soldier to have their dead husband's child. When sperm banks began opening in the midfifties, the three men infiltrated their supply with their hero sperm and increased their herd. All went undetected for fifty years, until an IED explosion in Iraq blew the lid off a program that began in 1942. DNA, used to identify body parts, exposed the Sperm Soldier program. Two of its founders, still alive, went to face the music, while military leaders struggled to figure out how this could be possible.

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

Book excerpt: Did you know that Kellogg's cornflakes were supposed to cure masturbation? Why was the Catholic church so insistent that sex could only be performed in the missionary position? In this book, you will find out why to testify meant to grab someone else's testicles, and why young boys in Papua New Guinea thought they had to drink older men's semen to attain puberty. St. Augustine believed that semen was a fluid that transmits Adam's original sin to every unborn child, Chinese and Indian scholars thought that it gives a person vitality. This book will tell you the ancient secret of achieving multiple male orgasms, and give you the recipe for semen infused French crepes. It covers 5000 years of semen history from an ancient Egyptian god performing auto-fellatio, to today's over one million Americans suddenly discovering that their biological father was an anonymous college student earning $10 a pop at the local sperm bank. Called everything from a magic elixir, the giver of life, to the essence of sin, this is its story
Download or read book Being a Sperm Donor written by Sebastian Mohr and published by Berghahn Books. This book was released on 2020-08-01 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: What does it mean to be a man in our biomedical day and age? Through ethnographic explorations of the everyday lives of Danish sperm donors, Being a Sperm Donor explores how masculinity and sexuality are reconfigured in a time in which the norms and logics of (reproductive) biomedicine have become ordinary. It investigates men’s moral reasoning regarding donation, their handling of transgressive experiences at the sperm bank, and their negotiations of gender, sexuality, intimacy, and relatedness, showing how the socio-cultural and political dimensions of (reproductive) biomedicine become intertwined with men’s intimate sense of self.
