The Case of the Female Orgasm: Bias in the Science of Evolution - Softcover

Lloyd summarizes dozens of evolutionary accounts of the female orgasm--and knocks them all down. Like [Stephen Jay] Gould, she thinks the female orgasm is purposeless; which is not to say pleasureless. And she extends the charge of bias, charging that too many scientists take the male-centered view that the female orgasm is closely linked to heterosexual intercourse and reproduction. -- Christopher Shea Boston Globe 20050424 It's been 52 years since scientists first considered the female orgasm a legitimate object of scrutiny (thank you, Dr. Kinsey). But they still can't settle on its raison d'etre...Lloyd knocks down all but one of the 21 existing explanations. Along the way, she makes a critical distinction between sexual arousal, which she says is critical in evolutionary terms because it makes women want to have sex (and thus results in pregnancy), and female orgasm, which she argues is merely a bonus...Lloyd settles on the unpopular but, she insists, most scientifically solid theory available...From an evolutionary perspective, female orgasm is superfluous...Lloyd hasn't written off the possibility that an 'obscure' and 'exquisitely designed' Darwinian function has yet to be discovered. But for now, she makes a convincing case that from an evolutionary perspective, female orgasm is just the icing, not the cake. -- Sue Ferguson Maclean's 20050429 [Lloyd's] study of evolution and orgasm offers the most thorough and serious treatment of the subject to date--and strongly rejects the claim that orgasm in women serves an evolutionary purpose. Lloyd has scrutinized 21 evolutionary accounts of female orgasm and makes a convincing case for the single account that treats orgasm as a happy accident, a byproduct of the role that male orgasm plays in reproduction and the sharing of early embryonic tissue by the male and female genitalia. The other 20 theories she dismisses as illogical or incompatible with data on women's sexuality. This time the press has it right. Lloyd's analysis is worth all the attention. -- Amanda Schaffer Slate.com 20050526 Okay, you have to be a science nerd to read this, a Stephen Gould fan, but what's here is [fascinating]. Really, the most radical book about how female orgasm has been so sensationally misunderstood and manipulated. Lloyd doesn't draw political conclusions--but you sure will. -- Susie Bright susiebright.blogs.com Lloyd's book is penetrating and tantalizing, even intensely satisfying...Her findings about the scientific process really are something to scream about. -- Alison Motluk Toronto Globe and Mail 20050528 The conclusion, Lloyd argues, must surely be that the female orgasm has no biological function. Rather, it's on a par with the male nipple--an accident of shared developmental pathways in the early embryo. Because women need nipples to suckle their babies, men end up with rudimentary versions too. They may not give milk, but like the female's they have erotic sensibilities. As for genitalia, because men need ejaculatory penises, women end up with clitorises capable of similar sexual pleasures. Lloyd reckons that biases in evolutionary thinking have blinkered generations of mostly male biologists. It is time to give up the adaptationist's fallacy and face facts. The late Stephen Jay Gould, who encouraged Lloyd's long-standing investigation, must be cheering from above. -- Gail Vines New Scientist 20050514 The Case of the Female Orgasm is of particular interest because it offers a fairly accessible account of competing scientific theories, how they are presented (and accepted), and what evidence they are based on. The data on female orgasm is shockingly flimsy, and Lloyd nicely shows how even carefully conceived experiments (such as for testing the upsuck theories) present a host of problems. Far more troubling, however, is what the scientists do with that data, often using it as they see fit--or simply incorrectly using it...This is an important book, and highly recommended to all scientific practitioners (who might be reminded of the bias that can so easily creep into their work) as well as those who interested in everything from scientific methodology to the role of science in society. The Complete Review Underlying biases exist throughout science, but surely nowhere in as extreme a form as in research into female sexuality...Elisabeth Lloyd neatly dissects the history of these biases and their results in The Case of the Female Orgasm. -- Sarah Venis The Lancet 20050903 She has an interesting and important set of theses. On top of that, her argument has a straightforward, logical structure...I recommend Lloyd's book to all philosophers of biology and students of human evolution. -- Dr. Rob Loftis Metapsychology Lloyd asks whether female orgasm is really related to reproductive success. The search for an answer reads like a mystery story and involves the critical examination of 18 theories developed on the premise that the human female orgasm is an evolutionary adaptation. The author invalidates each of these theories by an examination of their assumptions and, in many cases, the frailty of their supporting data...With its 355 references, this book is a study of the power of a careful analysis of data to show the weaknesses of certain theories. -- W. P. Anderson Choice 20050901 In this scientific review of the literature on women's ability to orgasm, Lloyd lined up thirty years' worth of studies designed to prove that women's orgasms evolved solely to make us better at reproducing and proceeds to demolish them all due to their crappy data, bogus assumptions, or fatal bias. She instead makes a case for men and women having separate, autonomous sexuality. Human orgasm evolved because men need it to reproduce, and women got it as a developmental byproduct. How women use that gift is ours to determine. Feminism and scientific theory can be uninspiring bedfellows, but Lloyd proves here that tenacity and hard work can bring them to a readable climax. -- Beth Brown On Our Backs 20050901 Elisabeth Lloyd provides a comprehensive and critical review of evolutionary explanations of the female orgasm. Through her extensive analysis of 37 years of research on the topic, she argues against the prominent theory that the female orgasm is an adaptation that has evolved to improve reproductive success...Lloyd provides a careful and impartial analysis of the validity of the findings from cross-cultural, animal, and human sexuality studies. Contrary to the adaptation perspective, Lloyd supports the theory, originally proposed in the late 1970s, that the female clitoris and orgasm are by-products of the embryological development of the penis and orgasm in males...The work touches on many of the biases that negatively affect scientific rigor and consequently (mis)shape our understanding of women's sexual functioning. -- Jayne E. Stake and Amy K. Silberbogen PsycCRITIQUES Lloyd is a philosopher of science interested in evolutionary biology, and she provides a measured scholarly evaluation of both the adaptive and nonadaptive explanations for human female orgasm...Her meticulously researched book examines 21 explanations for the evolution of female orgasm...The book becomes about much more than an aspect of human sexuality. It is an examination of how evolutionary biologists think, and how their system of gathering and evaluating knowledge can falter. Her reasoned approach is refreshingly free of jargon in a field that sometimes seems abstruse for its own sake; even if one does not agree with Lloyd's conclusion, the book provides a blueprint of how to critically evaluate scientific arguments. -- Marlene Zuk Perspectives in Biology and Medicine In this engaging and carefully argued account, philosopher Elisabeth Lloyd guides her readers through one of the most fascinating controversies in evolutionary theory. -- Mark E. Borrello Quarterly Review of Biology In this closely argued study, [Lloyd] shows how the leading evolutionary accounts of the human female orgasm are based on two flawed assumptions: that the female orgasm evolved because it contributed to reproductive success ('adaptationism'), and that female sexuality is like male sexuality ('androcentrism'). This is an important book that casts light on the biases that can prejudice science. -- PDS The Guardian 20061209 Upon your shelf...there probably isn't a book on evolution and the female orgasm. That's because it hasn't been written until now...Evolutionarily speaking, the female orgasm is 'for fun,' says Lloyd, and her theory...adds to its more intellectual joie de vivre. -- Michelle Humphrey Bust 20070201 Lloyd, a biologist, philosopher and science historian, uses the human female orgasm (an evolutionary development unique among primates), and science's wholly inadequate explanations for it, to focus on the ways science can be led astray by the biases of those practicing it. -- H. J. Kirchhoff Globe and Mail 20061230 Methodical and lucid, Elisabeth Lloyd's The Case of the Female Orgasm is an exemplar of accessible science writing. Those interested in evolutionary biology, philosophy of science, and feminism will find the book an interesting, if perhaps occasionally frustrating, read...Lloyd offers a rigorous case study showing how political and methodological biases have distorted the practice and results of evolutionary investigations of female orgasm...Although parts of the book are somewhat technical, Lloyd carefully explains most of the crucial concepts and educated readers will find it generally accessible. -- Meynell Letitia Hypatia 20070701

Why women evolved to have orgasms--when most of their primate relatives don't--is a persistent mystery among evolutionary biologists. In pursuing this mystery, Elisabeth Lloyd arrives at another: How could anything as inadequate as the evolutionary explanations of the female orgasm have passed muster as science? A judicious and revealing look at all twenty evolutionary accounts of the trait of human female orgasm, Lloyd's book is at the same time a case study of how certain biases steer science astray. Over the past fifteen years, the effect of sexist or male-centered approaches to science has been hotly debated. Drawing especially on data from nonhuman primates and human sexology over eighty years, Lloyd shows what damage such bias does in the study of female orgasm. She also exposes a second pernicious form of bias that permeates the literature on female orgasms: a bias toward adaptationism. Here Lloyd's critique comes alive, demonstrating how most of the evolutionary accounts either are in conflict with, or lack, certain types of evidence necessary to make their cases--how they simply assume that female orgasm must exist because it helped females in the past reproduce. As she weighs the evidence, Lloyd takes on nearly everyone who has written on the subject: evolutionists, animal behaviorists, and feminists alike. Her clearly and cogently written book is at once a convincing case study of bias in science and a sweeping summary and analysis of what is known about the evolution of the intriguing trait of female orgasm.
