Published to acclaim and controversy a decade ago, Sperm Wars is a revolutionary thesis about sex that turned centuries-old biological assumptions on their head. Evolution has programmed men to conquer and monopolize women while women, without ever knowing they are doing it, seek the best genetic input on offer from potential sexual partners. In this book, best-selling aut ...more

'Hello Tom.'

'Oh, hello Mrs. Harding. I'm sorry, my parents aren't at home...'

'Laura. I told you last time to please call me Laura. We worked out that I was only eight years older than you, remember?'

'I'm sorry... Laura. They've gone to...'

'Yes, of course. They've gone to the premiere of the play that I have been looking forward to all week, except that my bloody husband had to cancel and go to a terribly important meeting when the bloody taxi was already standing outside. Sometimes I wonder why

I had been asking sex questions on a human evolution group, and was told more than once to read Sperm Wars. "It explains everything." The book focuses heavily on infidelity, which I really didn't want to think about at the time, and explains the biological basis of sexual behavior. I was a little worried about "knowing too much"; that this knowledge would depress me and ruin my sex life. I bought a copy and lost it before reading it.

Recently, it came up in conversation again, and, feeling more a

Ok, I have nothing against softcore porn. I hate unsubstantiated psuedoscience. This book crams the two together. I want my science porn free. I want my science to cite sources. I want my science to be free of cultural agenda and bias. Alas, Baker failed me thrice. Much of what he describes is substantiated scientific theory that has been presented properly in other works. Some is rampant speculation. The porn that begins each chapter adds NOTHING to the topic at hand; not even detailed case stu
Well this book was always going to split the field, what with it's open, frank and polemical discussions of rape and prostitution. This is a fascinating text that is well worth reading with an OPEN MIND.

There are conjectures made that seem to disgust some reviewers on this website. What they seem to consistently miss, however, is that our views on social conduct and our sense of right from wrong is a remarkably recent cognitive development when viewed on an evolutionary timescale. So these conje
Sperm Wars made me realize how evolutionary biology got such a bad rap. Through this book, Robin Baker alternates sexual scenes with explanations of how the physical battle to procreate that happens internally can lead to seemingly irrational, immoral, or simply puzzling behavior, ranging from infidelity, to why the desire of when and how the female has an orgasm changes, to why group rape occurs.

Baker provides information on how sperm ratio differs in different sexual contexts, what role the c
Oh my gosh this is cuckold porn disguised as a biologists view of the social realities of reproduction.

Even in his preface he admits there are many biologists who will view this book as a complete work of fiction, but the first time I read that did not have the same impact it had as when I was done.

The entire book is comprised of "examples" he gives about sexuality, and he then explains his point of view on what "transpired" in his imagination, he explains they are not "real" situations, but are

It would have been interesting except some basic research indicates that most of the premises upon which this book was written are total crap. Very much of the 'women are evil cows after our vital essence' ideology with some penis envy overtones presented as scientific fact. Totally ridiculous book to have been written in this century.
This is the worst pseudo-scientific book I have read since The Naked Ape. It's hard to believe it can be called non-fiction. The copy I was given seems to be a vanity publication. The research seems opinion based and is not scientifically documented at all in the book. There are no references or citations and the fictionalized case studies are nothing more than soft porn. I wasn't surprised to find out that Dr. Baker has been completely discredited by his colleagues in evolutionary biology. I wo ...more

Recommends it for: Anyone interested in love, sex, or science
Absolutely fascinating. I learned so much I don't know where to begin. Did you know that 99% of sperm's primary function is to do battle with other mens' sperm inside the woman, and that only 1% is capable of fertilization? The woman's orgasm is her way of helping the sperm of the man she prefers. 10% of children's real dad isn't the man who thinks he's the father. Just an amazing scientific work, well written, funny, and informative.

This is one of the most fascinating books I've read in the last few years.

In retrospect I am really amused at some of the reviews for this book on this site and elsewhere from women who are, for lack of a more adequate term, butthurt over the contents of the book. Sure, if taken from a certain misandrous point of view the stories written by the author can be seen to be very damning towards women. The trick is that these women (and some self-hating men) seem to be stuck in a (probably religious)
Here's an explanation of the hangover after the free lovin' 60's, and where you got that red hair!

So far it seems a bit gratuitous, just partly credible & somewhat unfair to women. Would be a weak echo of the selfish gene, except that SW anticipates that book by decades. On the plus side, huge points for boldly, (if somewhat clumsily) exploring a new genre space, including titillating and episodes which behavior he then ties into the sperm wars.

Baker did his best to show various "reproductive strategies" without moralizing sex. Evolution of "whatever works," human behavior as strategies leaning towards better reproductive success. I love this kind of thinking.

This is a great introductory book to evolutionary psychology. Just be careful not to get too attached to the conclusions. Baker takes some observable facts (vagina's PH is hostile to sperm, and vaginal mucus is a sponge barrier blocking the sperm from the egg) and explains his f
I don't usually enjoy books in the field of science, but this one was an exception, even though at times it was could be rather provocative and distasteful. But wow, a lot is going on 'down there,' and it has a greater impact on our behavior than we would like to think. It also provides reasonable explanations for seemingly strange behaviors (sexual and otherwise). The book is presented in a series of 'scenes' which serve to build upon one another in order to introduce more complicated concepts. ...more
This is a very silly book about a very interesting topic - why human sexual habits evolved to be the way they are. Unfortunately, absolutely no evidence is presented for any of his ideas (the author sort of lamely suggests reading another of his books if you want the hard facts, as though there is no possibility that the general public could handle meaningful scientific argument). As with most theories of how human behaviors evolved, there's a lot to critique and question, but we never get a cha ...more

I promise I'm almost done with these books. Even my review may be offensive to some, so be warned.

This is another of the evolution books I brought out to research my paper.

Baker has best answer I've found to why we masturbate. He argues that self-stimulation is a biologicalimperativewith a very particular design. It helps us regulate our semen quality to maximize both our chances of procreation as well as ourchancesof outcompeting a rival's ejaculate if our mate has been unfaithful. The way it
Not really sure what the big deal is. There isn't anything here that isn't in any standard textbook on human sexuality (or at least nothing substantiated). I have trouble thinking of this as a 'science book'; not one footnote, no bibliography, only a back cover allusion to the author's many publications during a 16 year career as a university lecturer.
Sean Goh
If one reads this book with an uncritical mind, you will be apt to find it very interesting, with many conclusions that make sense.

Yet it must be noted that this book lacks references, and anecdotal conjectures (for the evidence, read my other science-heavy publication!) aren't quite the same as scientific hypotheses backed by evidence.

A simple search disproves one of the more interesting claims (sperm specialisation), so there.

Baker's main thread seems t
Very Interesting. My only complaint that it gets hard to read the case studies as the book goes on, since they refer to previous cases by number only, and you have to remember that Case 34 was the one with the orgy (and so forth)

awesome book! Revolutionary thoughts. It will change your life and your marriage!

Not being an evolutionary biologist by trade, I don’t have a single, scientific leg to stand on as I write this, so there’s my disclaimer… but:

There’s something dodgy about this book. Some of the arguments seem absolutely sound, some do not. For instance, there appears to be an illogical standpoint on condoms. To suit the argument, the man’s body can either detect wearing one, or not. There are others where I wonder if too complex a set of behaviours are being put down to biological imperatives,

The behavior of human sperm is fascinating: only a small percentage are actually fertile enough to inseminate an egg. The rest exhibit complex features that apparently exist to block or kill the sperm of other males inside the same woman's body.

Under what behaviors and reproductive strategies did humans evolve to developer sperm like this? If you're interested in finding scientific answers to that question then this book will disappoint you. It is a collection of made up erotic stories accompani
This book is both depressing and sobering, but at least it was interesting to realize that many actions that men and women take are not taken because of conscious or rational deliberation, but are rather the result of subconscious and instinctive drives which are then rationalized after-the-fact and according to the actors preferences, morals and ideology. This was deeply unsettling as it appears to chip away at our supposed freedom of choice: why do we do the things we do - it is not because we ...more
This was an interesting read, albeit a bit arduous at times. Baker's thesis is that all human sexual behavior can be explained from a biological stand point, an ambitious view that he doesn't fully succeed in demonstrating. While many of the phenomena he discusses, such as the widely varied orgasmic patterns observed among females compared to the highly predixtible patterns seen among males, can be convincingly attributed to biological causes, others, such as the various cross-cultural taboos ag ...more
At first I loved the book. So much of the information, both biological and sociological, were things I'd never heard of before. But as the books goes on, repeating certain details to death and gliding over others with little explanation, you realize that many theories are being presented as fact. At least, I can only assume they're theories, because I'm expected to just take it in good faith that all of these interpretations of "studies" are accurate, unbiased, and thorough. Without hard data, o ...more
Interesting but often too roundabout and redundant--

Robin Baker does offer an interesting interpretation of human sexuality, but some points he makes seem to be blatantly assumed than based on solid scientific evidence, such as specifically how men gain information about their mates from oral sex (Scene 10), what mechanism men use to adjust the number of sperm in their ejaculates (Scene 4), and how women's bodies could be said to "manipulate" their emotions to reduce the chances of conception (S
El llibre mira això de la reproducció sexual humana des de la perspectiva de la biologia evolutiva. És a dir, sota la premissa que el comportament sexual humà es basa en estratègies reeixides, i que per tant tot ha de tenir una raó en els mecanismes evolutius. S'interpreta la causa a partir dels efectes. En canvi, el llibre d'en Tobeña estudia les causes per si mateixes, els mecanisme neuronals que ens fan tenir el comportament sexual que tenim. Per dir-ho d'alguna manera, la primera aproximació ...more

This book has NO REFERENCES. None. It has controversial theories and sexual vignettes (albeit some interesting ones) that root our sexual instincts and relationship behaviors in purely biological terms. That isn't a novel approach: what is novel is the purported contrivances the female body has evolved to collect sperm; his perspective on homosexuality; and his contention that female bodies are constantly trying to foment sperm wars within themselves. It's all highly cerebral and not very scient ...more
David Fleming

This was a disturbing book that took a while for me to get through. And I'm not sure why this is the case because (in my opinion) the book is a lot harder on women than on men. THE MORAL ANIMAL in contrast is a book which also derives from similar evolutionary pyschology principles and seems to be fairly hard on men.

Everyone should read this book and yet ...I'm not exactly sure why? Maybe because much of the information that exists between these pages has the ring of truth to it and I'
Nick Arkesteyn
I have been quoting this book for years. About time I read it! I read this book in one sitting. It is a fascinating book that anyone who has ever had sex should read ;)

My only recommendation is that you give yourself at least one hour to clear your mind before you see your partner after you read this book! You will have an interesting pair of infidelity glasses on for a little while.
