This week, the FDA approved Lybrel, a contraceptive that enables women to stop menstruating. Predictably, this produced a flood of concern about the cosmic implications of it all, even though, as I understand it, the decision to include a week of placebos so that women who are on the pill would have periods was made because several decades ago, women found it less disconcerting. (Similarly, when the first cake mixes were developed, they had powdered eggs in them, but tests showed that people preferred to add their own eggs, since it made them feel as though they were actually baking.) What's truly perplexing is that a lot of the sillier things are written by women. For instance:
"It's unclear whether women will embrace this new pill, which contains the same formulations of estrogen and progestin used for birth control pills for decades, but its arrival marks yet another step toward the blurring of the genders.As 21st century women dominate the universities and continue to climb the executive ladder, and metro-sexual men explore their feminine side, it's harder to define what it means to be a woman."
Um: no, it's not:
"Main Entry: wom·an
1 a : an adult female person"
See how easy? Even those of us who are contributing to the blurring of the genders by taking up university positions can manage that. We are not confused, even though, according to the author, "it is menstruation that has historically set women apart from men." Luckily for women who are pregnant, nursing, or menopausal, there are certain other telltale signs: breasts, a vagina, a uterus, pregnancy, no Y chromosomes. So most of us manage to figure out that we are not men even when we aren't having our period. Although Lybrel does seem to have led one woman to get confused about women's separate identities:
"On matters concerning the female reproductive system, it's important to remember J.S. Bach. Specifically, Anna Magdalena Bach, the second, highly fecund wife of history's most potent composer."
Honestly: you can't make this stuff up.
But the strangest of all is this segment from Fox News. Watch the face of the woman from NARAL as she slowly realizes just how nutty her counterpart from the Abstinence Clearinghouse is. ("I want more babies! More babies! We want more babies!")
Meanwhile...
In unrelated news, some evolutionary psychologists are coming up with some peculiar theories about why women have orgasms:
"Shlain believes orgasm is a reward to women, a little something to entice them to have sex rather than focus on the prospect of death in childbirth. “Once she knows death is associated with sex, she needs to have an impetus to keep having her do it,” he says."
News flash: women, like men, normally do not have sex with someone because they think to themselves: hmm, it would be great to have an orgasm. I wonder how I might manage that? Oh, right: sex. That sort of instrumental reasoning is, roughly, why we do some things: getting the oil changed, visiting the dentist, and so forth. In the case of sex, however, most of us have a more direct kind of motivation. The thought of future orgasms normally has nothing to do with it.
Here's an even stranger explanation:
"He thinks it’s possible that orgasm is a way for a woman’s body to tell her mind that she is copulating with a powerful, attentive, secure male. That means good genes. “Perhaps orgasm is an evaluation of a male, a way females inform themselves” of the kind of male they are with, he says."
On reflection, I'm not even going to get into what's so wrong with that one. I just hope there aren't any vibrators reading this.
Finally, what would a post like this be without an appearance by Mr. Play-Doh and Bacon himself, Ace? Unfortunately, he has decided to post about cosmetic vaginal surgery. Here's his explanation:
"This is all very similar to women getting their nails done. Women don't do that for men; they do that for other women and themselves. No guy on earth has ever noticed a woman had "pretty nails" and a "nice pedicure" until she told him to compliment her on it."
I'll turn this over to Amanda:
"Hard as it may be to believe, women don’t actually whip off our pants and investigate each others’ vulvas when we’re getting together to hang out with our girl friends."
It's true. We don't.
Even more unfortunately, Ace doesn't stop there:
"And no guy in the world is even noticing labial size. Unless they're enormous Dumbo-flaps or something. In which case, they may be noticed, but guys being guys, we probably find it to be a turn-on just because it's somewhat unusual.So don't pin this one on us, Marcotte."
Dumbo-flaps??
What with all of us inspecting one another's labia over coffee and all, why on earth would anyone need to pin the kind of insecurity that would lead someone to contemplate having surgery on their genitalia on guys who talk about "Dumbo-flaps"?
I can't imagine.
Speaking for the male of the species, I think we're all happy not to need to use menstruation to discriminate between men and women.

The evolutionary psychology explanations of orgasms don't sound that implausible. The first one seems like it's probably true. Sex is fun & satisfying because people who enjoy sex tend to have more sex, and orgasms are part of what makes sex fun & satisfying. So our ancestors who had pleasurable orgasms had more sex and left more offspring than any would-be ancestors who didn't have pleasurable orgasms. Seems like that could go for men as well as women. There's no need for people to deliberatively think ahead and consider the possibility of an orgasm - it could even happen through conditioning (like Pavlov's dogs). Rewarded behaviors tend to get repeated, for all animals, and orgasms are one way in which sex is rewarded.
The other theory is weirder but not necessarily false. I don't know how well all the details fit this theory, but there is some research showing that a woman's chances of having an orgasm depend on features of her partner (like symmetry). Vibrators don't invalidate theories about the evolution of sexuality any more than candy bars invalidate theories about the evolution of eating, since neither was around when humans evolved.

For some reason, I had never heard anything by Frank Zappa when I (17) arrived in France to spend half a year living with a family I had never met before. They had two twins, boys aged 13, and I had been instructed by the program I was on not to show any favoritism towards either. This was hard, though, since one was friendly and talkative, while the other more or less incarnated every bad thing about sullen male adolescence.
So I was trying to figure out how to talk to Sullen, without success, when one day I got home from school to find him listening to a new record that he was completely taken with. (I should say that Sullen spoke no English.) I went in to listen, and the first thing I heard was: "You look like a penguin in bondage, boy". I burst out laughing. Sullen was horribly offended and wanted to know what was so funny. I was trying to figure out how to translate the lyrics into French ("vous avez l'aire d'un peguin enchaine", I think I began), and then he was even more miffed, because he didn't get what it meant, and besides, he had been listening to something with bizarro lyrics and hadn't even been aware of that fact.

The really disturbing part of this video was that the NARAL woman didn't know how to deal with the blonde clown. The ONLY way to deal with these yahoos is to hit back hard, call them on their bullshit, and insist that they not dominate the conversation.
It is endlessly frustrating watching people on my team play nice and get steamrollered. Liberals need to figure out that we are not dealing with "nice" people interested in a fair-minded exchange of ideas. Those people left the rightist camp years ago.

Shlain is one of those authors who had an interesting, if wacky, idea, but totally lost me when his writing meandered into an area I knew something about and totally botched it. In this case, I think it was something about how nerves that drastically overstated the degree to which they are electrical signals.
Posted by: Nathan Williams | May 28, 2007 at 12:38 AM
Yes, I have to admit to being dense on the evolutionary fallacy going on here.
It would seem to me that people, um, do have sex in order to have orgasms. Sure, there might be a more direct motivation too, but why wouldn't they bleed into one another when there's conditioning involved. I mean, you can say some people drink coffee because, well, they like coffee. And some people want the kick. What's so odd about thinking that some people who enjoy the taste of coffee in fact drink more than they would otherwise because of the kick?
And on the second point, I've read all kinds of stuff about women enjoying sex more based on (seemingly unrelated) physical characteristics of men. So why should this be a shock?
What I really don't understand is why, in a species that pair bonds, the motivation not to kill your partner wouldn't cut both ways. I mean, geez, I don't want to kill my girlfriend.
What's more, you'd think having sex after having had one kid would imperil the upbringing of the existing kid.
There would be these kinds of effects if the death calculus came into play in thinking about whether to have sex. If they don't come into play, maybe that's reason to think that we really don't think about death when we get it on.

Elizabeth Lloyd has written a book, "The Case of the Female Orgasm." It's not so much an attempt to explain the origins of female orgasm, as an attempt to document the strange contortions that evolutionary speculators have put themselves into in trying to fashion explanations.
a sympathetic review here:

Ara: It would seem to me that people, um, do have sex in order to have orgasms.
The evolutionary fallacy here is that, for women, orgasms are not in any way linked with *checks posting rules* babymaking.
In general (so I'm told: I have no personal experience in this, ah, area...) a man who has an orgasm also has an ejaculation. While there are various things that a man can do to ensure his ejaculation will not contain any fertile sperm, I gather there is nothing a man can do to avoid ejaculating when he has an orgasm.
Women produce fertile eggs on a 25-30 day cycle that has absolutely no connection whatsoever with our ability to have orgasms. Furthermore, the method by which a man's ejaculate gets to make possible contact with a woman's egg - assuming she has one available - is not the most effective of methods for most women to achieve orgasm.
(Writing this in accordance with the Posting Rules has been slightly amusing.)

Ara: "It would seem to me that people, um, do have sex in order to have orgasms."
On reflection, I wonder whether this might be a gender difference. In my experience, at any rate, the desire to have sex and the desire to have an orgasm are quite different, and the latter only puts in an appearance when one is already, etc., etc.

There are traditional chinese methods that involve, ah, ejaculating into the bladder.
Women produce fertile eggs on a 25-30 day cycle that has absolutely no connection whatsoever with our ability to have orgasms.
But the likelihood of having those eggs get fertilised *could* have something to do with the chance for orgasms.
I once had a link that claimed the human female reproductive tract is strangely shaped. Most primates have the equivalent of the clitoris etc inside the vaginal opening, while ours is displaced. Another primate has it like ours, gibbons I think.
But I misplaced the link and didn't find it now, instead I found things that claimed primate clitoral positions and shapes are greatly varied. The original author was making a point, it wasn't exactly a crackpot site but not disinterested either. So I don't know.
At any rate, if human women have less reliable orgasms than other primates, that might itself have been selected. Human women are capable of having far more children than they can raise effectively, and it makes sense to resist that temptation. If we were prey animals that can expect to lose lots of babies to predators then it would make sense to maximise birthrates and minimise the needed parental care.
It's plausible that our structures have been subject to natural selection, but it isn't necessarily easy to guess what exactly has been selected.
Furthermore, the method by which a man's ejaculate gets to make possible contact with a woman's egg - assuming she has one available - is not the most effective of methods for most women to achieve orgasm.
Probably humans have not had much selection to maximise the chance of pregnancy per mating.
I've seen claims that orgasm does increase the chance of fertilisation -- that it somehow transports sperm that would otherwise have a harder time arriving. I don't know how correct that is. The actual scientific literature seems confusing and confused on such topics, and the popularised stuff is even worse.
The basic evolutionary-theory principle seems sound. Genes get selected when they maximise the production of offspring that themselves reproduce. What's hard is to predict what will get that result in a human context, where social status may affect reproductive success more than anything else.
Posted by: J Thomas | May 28, 2007 at 11:17 AM
Keeping one eye on the posting rules ... there is some evidence that a woman who has an orgasm after a man ejaculates in her may be more likely to conceive than a non-orgasmic woman, or a woman who achieves orgasm before the man. During female orgasm, the uterus and cervix contract, the cervical opening dilates, and the cervix itself dips into the upper area of the vagina where the ejaculate has been deposited. (Safe for work link to about.com is here).
But it's a pretty damn Rube Goldbergian mechanism nonetheless. A man who ejaculates into a fertile woman at the right time of the month has a pretty good chance of impregnating that woman. It is highly unlikely, although not impossible, that non-ejaculating males become fathers. Female orgasm increases the odds of that woman becoming pregnant, but is not a necessary pre-requisite, as all sorts of non-orgasmic women get pregnant every day.
Posted by: Mary | May 28, 2007 at 11:29 AM
Maybe easy orgasm for women makes them more interested in sex generally whether they can be impregnated or not, and by being more interested, they are more attractive to men, and more likely to keep a father happy and with her, and therefore the child is more likely to survive.

FWIW, the single biggest difference between all other primates and us is that we go through menopause. We don't keep ovulating our entire lives. At some point, with thirty-odd years ahead of us, we stop ovulating - it ceases to be possible to have children of our own. This created the grandmother - a woman with a lifetime's experience in how to bring up children, who was not currently bringing up any children of her own.
And I think it far more probable that, rather than relying on the chancy and improbable links between orgasms/sex/male provider sticking around/children surviving, female menopause became an evolutionary positive because children with grandmothers were more likely to survive.
Posted by: Jesurgislac | May 28, 2007 at 11:44 AM
I was particularly impressed by the argument that NARAL and Planned Parenthood have been fighting to control women by, um, giving them reproductive choices. It was almost as funny as the "Big Pharma" mantra, as though drug reps are grabbing women on street corners and shoving pills down their throats.
Posted by: Ginger Yellow | May 28, 2007 at 11:48 AM
"Orgasm = wants more sex" is a reasonable behavioral equation - until you look at other primate species' behavior. Esp. bonobos.
They seem to regard the primary purpose of sexual behavior to be social bonding and conflict avoidance. Much of what we call "sexual behavior" (particularly the non-intercourse parts of it), is apparently grooming and play behavior to them. To put it more crudely, they diddle around with one another constantly, with little regard for gender for age, and the result is a happy, cohesive troupe.
Since women's orgasms have no biological connection to pregnancy, and since we are primates, and since heterosexual intercourse is the least effective way to bring a woman to orgasm... it seems clear to me that the purpose of physical, sexual pleasure isn't to make more babies, but to facilitate social cohesion.
Posted by: CaseyL | May 28, 2007 at 11:51 AM
Er: no.
Well, I guess that put us in our place, didn't it? I was referring to the same study that Mary was, and I don't vouch for it. Might be true, might be true sometimes to some extent, might not.
I agree that the grandmother role is likely highly selected. Was the selection for menopause or was it for long life? Humans live rather longer than most animals. Did we once maintain fertility life-long and then menopause was selected? If so, the selection may have been for reducing the overhead of multiple defective babies -- Down's syndrome etc. Grandmothers who didn't have stillbirths and disabled children would live longer and also provide more help of many sorts to their relatives. But grandmothers whose babies were as good as younger women's babies might be for many purposes as useful as younger mothers.
Babies conceived barely-premenopausal have something like a 20% rate of Down's syndrome now, and that isn't the only problem. So it makes perfect sense that we'd select for long life and also for menopause, rather than select for long life and more eggs and then select for reduced genetic defects among old eggs.
I think you have one of the more supportable evolutionary arguments here. There likely has been selection on the other issues also, and there may be supportable arguments about it even if the current arguments look particularly flaky.
I fondly remember a collection of arguments about why human men can't tell when a woman is fertile. Lots of female mammals go into heat, and only mate then. We do a lot of mating that is very unlikely to result in pregnancy. So they were elaborating more and more elaborate arguments about this. And then a woman made the argument that lots of women can't themselves tell when they're fertile. Why would that be? And she made the argument that women who wear themselves out raising more children than they would choose to, are selected over women who have only as many children as they want.

J Thomas,
Children born of younger mothers were more likely to have mothers until they were old enough to care for themselves, and therefore more likely to survive. The short and brutish lives of our ancestors probably did not provide very many post menopausal grandmothers. It seems to me that menopause would be as likely an evolutionary step based on survival rate of the children born to older mothers as the survival rate of the mother.

Oh, I see. I misunderstood: I thought you were making a different kind of argument.

No other primates experience menopause. Then again, no other primates live as long as we do. (Proportionally speaking, or so I read in some Stephen Jay Gould essay, humans live twice as long as our metabolic clock tells us we "ought" to live.)

FWIW, the single biggest difference between all other primates and us is that we go through menopause. We don't keep ovulating our entire lives.
Amother explanation, of course, is that this is largely irrelevant. We evolved under conditions which ensured very few proto-humans lived to see grandchildren, and menopause may be an artifact of a reproductive system pushed beyond the conditions it evolved under.
BTW, I'm not dismissing the "grandmother" hypothesis; I'm just wondering whether its as important as people seem to think.

Posted by: xanax | May 28, 2007 at 03:56 PM
J Thomas, Mary, and Jesurgislac, article that Hilzoy linked mentions the theory that orgasms increase the chance of conception (which they call the "uterine suck-up theory") and says that it "has been more or less proven false."
The article also raises "hidden ovulation" as a puzzle and discusses possible evolutionary explanations, including:
1) to make it more difficult for women to avoid pregnancy by using fertility awareness methods of birth control (especially given the health risks associated with pregnancy in those days)
2) to facilitate pair-bonding, since a male can't just swoop in when the female is fertile; they have to have sex all month for him to be sure to have hit the fertile part of the cycle
3) to make it easier for women to have an affair during the fertile part of the cycle, since her partner can't "mate guard" as effectively when he can't focus his attention on the few days per month when she is fertile
There is a growing body of research, somewhat consistent with the 3rd hypothesis, showing how women's sexual desires and behaviors change during the ovulatory cycle. There is evidence that the fertile part of the cycle is when women are most likely to prefer men with signs of good genes (e.g. symmetrical faces, pdf) and to seek out an affair (pdf), especially if their partner doesn't have good genes (e.g. a complementary immune system). This research also shows that you don't have to be explicitly aware of something for it to influence your behavior.

What I miss in all the theories is an explenation for why women can have so many more orgasms than men.
As far as the anti-mentruation pill goes: menstruation is really inconvenient even if you do not engage in copulation or related activities.
Before hearing about this US hype of volontary female circumcision I only knew one person who had her labia operated on; and she did it because biking hurt. Which is very inconvenient in the Netherlands, especially if you don't have driving license.

Article several weeks back in the NYTimes about what happens with ducks and the biological "war of the sexes" that has occured: "The drake has a corkscrew WHAT?!! And it's HOW long?"
Turns out that for some Asian species this "evolutionary war" has become, um, pretty aggressive due to the activity of the male ducks. End result: female ducks of this particular species have a labyrinth up there.....

there is some research showing that a woman's chances of having an orgasm depend on features of her partner (like symmetry)
And here I thought it was all about mastering the Venus butterfly....
That was my introduction to Zappa from an older cousin.

may I suggest you consider Courtney Cox's Asshole?
I'm sorry, but I just can't bring myself to click through on that one.
And what, no jokes about Bach's organ?

Francis,
Scientists should too, for that matter. The amount of nonsense I read based on speculation and not science regarding "explanations" of behavior that is allegedly based on evolution is far too great.
Dutchmarbel,
This is the first compelling argument I've heard in favor of American car culture to date.

You really should: it got Soloway an executive producer spot on Six Feet Under.

all these theories of why we women have orgasms keep ignoring the itsy bitsy fact that women's orgasms need have nothing to do with intercourse and fertility.
There's an extremely cool site www.dinahproject.com - lots of stuff on lybrel, orgasms etc..

Yes, but I'm beginning to think het women keep this quiet so that het men won't get discouraged. ;-)

Okay, so I don't have a comment of any actual relevance to this post, but I thought I'd share with you the means by which I arrived.
Essentially, I was reading a web-comic where the "retrograde wheelbarrow" was mentioned as one of the character's favourite sex positions. So I did what any right-thinking human being on this interweb we call The Interweb would do; I Googled "retrograde wheelbarrow sex position".
And it brought me here.
I love technology.

Well, I'm a regular reader of both ObWi and xkcd, but I didn't google when I read the comic.

There have not been conclusive studies in the event of taking Avodart [Dutasteride] in the presence of hepatic failure or renal failure. This drug is highly metabolized in the liver and advisable to be avoided in hepatic failure.
