The G-spot 'doesn't appear to exist', say researchers (now NSFW)
 
First, the news article:
Quote:

The elusive erogenous zone said to exist in some women may be a myth, say researchers who have hunted for it.

Their study in the Journal of Sexual Medicine is the biggest yet, involving 1,800 women, and it found no proof.

The King's College London team believe the G-spot may be a figment of women's imagination, encouraged by magazines and sex therapists.

But sexologist Beverley Whipple, who helped popularise the G-spot idea, said the work was "flawed".

She said the researchers had discounted the experiences of lesbian or bisexual women and failed to consider the effects of having different sexual partners with different love-making techniques.

The women in the study, who were all pairs of identical and non-identical twins, were asked whether they had a G-spot.

If one did exist, it would be expected that both identical twins, who have the same genes, would report having one.

But this pattern did not emerge and the identical twins were no more likely to share a G-spot than non-identical twins who share only half of their genes.

Mythical

Co-author of the study Professor Tim Spector said: "Women may argue that having a G-spot is due to diet or exercise, but in fact it is virtually impossible to find real traits.

"This is by far the biggest study ever carried out and shows fairly conclusively that the idea of a G-spot is subjective."

Colleague Andrea Burri was concerned that women who feared they lacked a G-spot might feel inadequate, which she says is unnecessary.

"It is rather irresponsible to claim the existence of an entity that has never been proven and pressurise women and men too."

Dr Petra Boynton, a sexual psychologist at University College London, said: "It's fine to go looking for the G-spot but do not worry if you don't find it.

"It should not be the only focus. Everyone is different."

The Gräfenberg Spot, or G-Spot, was named in honour of the German gynaecologist Ernst Gräfenberg who described it over 50 years ago. It is said to sit in the front wall of the vagina some 2-5cm up.

Recently Italian scientists claimed they could locate the G-spot using ultrasound scans.

They said they had found an area of thicker tissue among the women reporting orgasms.

But specialists warned there could be other reasons for this difference.

So, it appears that they simply asked women if they have a G-spot, and used those results to draw their conclusion? Sounds like bullshit for science. Also, the quotes from the researchers sound like they made their conclusions before analyzing the data.

Further Googling led me to the abstract (the full text is behind a subscription login):

KEYWORDS
G-Spot • Twin Study • Genetics • Heritability
ABSTRACT

Introduction. There is an ongoing debate around the existence of the G-spot—an allegedly highly sensitive area on the anterior wall of the human vagina. The existence of the G-spot seems to be widely accepted among women, despite the failure of numerous behavioral, anatomical, and biochemical studies to prove its existence. Heritability has been demonstrated in all other genuine anatomical traits studied so far.

Aim. To investigate whether the self-reported G-spot has an underlying genetic basis.

Methods. 1804 unselected female twins aged 22–83 completed a questionnaire that included questions about female sexuality and asked about the presence or absence of a G-spot. The relative contribution of genetic and environmental factors to variation in the reported existence of a G-spot was assessed using a variance components model fitting approach.

Main Outcome Measures. Genetic variance component analysis of self-reported G-spot.

Results. We found 56% of women reported having a G-spot. The prevalence decreased with age. Variance component analyses revealed that variation in G-spot reported frequency is almost entirely a result of individual experiences and random measurement error (>89%) with no detectable genetic influence. Correlations with associated general sexual behavior, relationship satisfaction, and attitudes toward sexuality suggest that the self-reported G-spot is to be a secondary pseudo-phenomenon.

Conclusions. To our knowledge, this is the largest study investigating the prevalence of the G-spot and the first one to explore an underlying genetic basis. A possible explanation for the lack of heritability may be that women differ in their ability to detect their own (true) G-spots. However, we postulate that the reason for the lack of genetic variation—in contrast to other anatomical and physiological traits studied—is that there is no physiological or physical basis for the G-spot.

So, it seems the news article was surprisingly accurate. I'm still not impressed. Opinions?

And xkcd is already on the case.

Maybe it shows up at a certain age lol I know mine wasn't located until I was 35!! God bless Dave :)

little_tippler 01-06-2010 06:50 AM

I saw this article yesterday too and wondered about it.

Well it's not like it's an organ you can identify, point and say 'look there it is'.

I don't know if it exists as well but I can say from experience that repeated stimulation of the area I have read to be the 'g-spot' in the correct way produces a different, more intense orgasm than usual. It's definitely not a button you can press to produce the exact same effects every time at will.

If it can be called an actual 'spot' I don't know, but I'm glad it feels that great ;)

Edit: "pseudo-phenomenon"? Riight.

LoganSnake 01-06-2010 07:05 AM

The g-spot is a myth. Like the clitoris and the female orgasm.

filtherton 01-06-2010 07:09 AM

Well, if you look at it another way, there is as much scientific evidence for the g-spot as there is for religious experience.

I believe in the g-spot.

Lady Bear Cub 01-06-2010 07:15 AM

Science will never be able to convince me that I don't have a G-spot. And Pluto will always be a fucking planet.

Redlemon 01-06-2010 07:45 AM

Some women don't like to have their nipples stimulated. If there weren't visible on the surface, these researchers would probably conclude that nipples don't exist.

Daniel_ 01-06-2010 08:25 AM

Don't forget that some researchers deny female ejaculation.

Toaster126 01-06-2010 08:34 AM

If g spot stimulation is wrong, I don't want to be right. :)

It's my understanding that the clitoris isn't just the head at the top of the boat, but continues inside a woman's body. There is erectile tissue and a shaft, it's just below the surface. When a penis (or sex toy) moves in and out of the vaginal tunnel and puts movement and pressure on the upper wall, it's putting that pressure and movement on the bottom of the whole clitoris, which I would imagine has a similar effect as that type of movement might have on the penis of a man or transgendered individual.

Then again, this isn't really my area of expertise. All I really know is that I've seen the effect of g-spot stimulation first hand on women and it would seem to exist.

What kind of obscure sample group is that?

I'll keep believing real medical science and the fact that i've actually *touched a blood engorged gspot before* over this wonky pseudo-science bull any day. The G-spot doesn't exist because a handful of pairs of identical twins dont both know how to work it? Sounds like the person running the study needs to go take some college logic classes.

blahblah454 01-10-2010 10:31 AM

I don't understand why this even matters and why they spend money on this. People enjoy sex, women enjoy their vaginas being touched certain ways. Can't we just leave it at that?

I like this notion. I was surprised to see this research, since I have never failed to locate the g-spot of any girl I slept with. But perhaps the idea that the g-spot is a religious experience would explain why, when I did, they always seemed to yell, "Oh, God, oh God!"

lovely25 01-13-2010 10:48 AM

Haha!! so I guess you know its bad when researches "can't find the g spot" :eek:
In all fairness though, their findings obviously are accurate to their research. If they tested with 1800 women, and found that 1800 women appear to not have a g spot stimulation area, then this is true, however - I think its kind of like seeing a ghost. If you haven't seen one then you will naturally be skeptical - if you've seen something like that then you don't know what to believe other than you know you saw something crazy.

I have seen women have earth shattering orgasms because of g spot stimulation. I have given women earth shattering orgasms because of g spot stimulation. Not all women are capable, true, and those who are may not have "A-typical" g spots, but they do exist in my opinion. You know, if you kiss the back of a woman's neck and it makes her orgasm every time - that's technically a g spot in a weird way. Or its a trigger point.

thermight 01-13-2010 12:51 PM

I know I had tried to find my wife's G-spot for 17 years. I would always rub what was supposed to be the right spot but she would not relax enough to let anything happen. The feeling like she had to pee took over. Finally about 2 years ago we got past that and now she is a full fledged squirter.

Besides no two women like the exact same things.

They should study those who claim they have a G-spot. They need to look at both sides of the evidence. Do it like mythbusters and go test one of those squirting porn stars to get big positive result before you call it busted. I think I just came up with the idea for a porn flick. A parody of Mythbusters.

The Journal of Sexual Medicine is a peer-reviewed publication, and King's College London is a well-established research institution. There's nothing pseudo-scientific about this.

Identical twins were used to demonstrate heritability. If two identical twins offer different answers when asked whether or not they have a G-spot, it rules out the possibility that the trait is heritable but not represented in the sample used.

The study was designed to examine the heritability of the G-spot, based on the fact that heritability has been observed in every anatomical feature studied to date. We can also hypothesize that if the G-spot exists as a significant physiological phenomenon, psychology or 'knowing how to work it' wouldn't be an issue, any more than it is for the glans or clitoris or other sensitive sexual organ. Based on that, the lack of correlation between genetically identical twins and G-spot prevalence would seem to suggest that the G-spot is indeed not a distinct physical structure. There are other possibilities for why some women respond so strongly to stimulation of the anterior vaginal wall, and further study would be required to determine the basis of the effect.

Sounds like you need to educate yourself on how science actually works before criticizing the experts.

Nope. I have an engineering degree, I understand scientific studies. I still disagree with the methodology of this report. Some women don't orgasm from clitoral stimulation; that doesn't make the clitoris nonexistent. The concept of the study is good; check for heritability among identical twins. The method for determining it I find faulty.

You have to learn to meditate. Meditation has significant effects on the body systems. Using that as an analogy, I disagree that "We can also hypothesize that if the G-spot exists as a significant physiological phenomenon, psychology or 'knowing how to work it' wouldn't be an issue, any more than it is for the glans or clitoris or other sensitive sexual organ".

Halanna 01-13-2010 04:05 PM

The estimated female population of the world in 2009 was 3,386,509,865.

They call talking to and having surveys filled out by 1804 of those a "large" study?

dippin 01-13-2010 04:28 PM

Now, to add on to my last post so as not to sound completely snarky: when it comes to sex, the discussion of nature versus nurture is ancient and hard to resolve. Twin studies are popular precisely because of that, as identical twins have the same genetic make up. Other studies have used twin studies to show that genetics explain a good deal of premature ejaculation and clitoral orgasm, for example, as twins would have significantly correlated responses to questions regarding those issues.

Regarding it being a "large" study, interviewing 1800 people regarding this issue is not a trivial matter. And how representative a sample is is not about share of the population interviewed, but sampling procedure. You can have a representative sample of any population you want with as little as 300 people, if the sampling is done correctly.

I think that when they say large, the mean that it's large enough to provide statistically significant results.

On a more general note, it would be nice if it didn't cost money to read the actual research paper, because the flimsy BBC writeup says a lot without really saying anything.

It would be interesting to see how the researchers addressed the possibility that some of their participants might have lacked sufficient sexual experience to know whether or not they had a g-spot. Or whether the prevalence of g-spots found among their participants is similar to the prevalence of g-spots in the general population.

I don't think this study disproves the existence of g-spots at all.

I'm not really sure what you mean to say by using meditation as an analogy. There is no meditative gland or M-spot; it's entirely a psychological phenomenon. Unless, then, you're arguing that the G-spot is actually psychological in nature (a claim the paper does not appear to refute), your analogy isn't valid.

56% of respondents reported having a G-spot. The paper would never have made it to publication if the researchers had stated there was nothing to this. Indeed, even in their conclusion (as offered by the abstract, which is the only material I have access to) that women may differ in their ability to find the G-spot, and that therefore their conclusion could be considered tentative at best.

Regardless, their logic is sound. If you poke a bundle of nerves, you're going to get a reaction 100% of the time. If not all women have the bundle of nerves, you would expect the breakdown to occur along genetic lines. Since not all women report having a G-spot, and heritability has not been demonstrated, it's not unreasonable to posit that there's no bundle of nerves in the first place.

to Halanna, 1800 is certainly a statistically significant sample size. Without full access to the paper one can only take on faith that they've accounted for sampling biases and margin of error, but then that's why the peer review process exists in the first place. I'm no statistician, so I'll simply leave that there.

thermight 01-14-2010 06:34 AM

What I see here is one of the differences in scientific approaches. Engineering is a hands on actually go and test the thing field. Medicine in many ways is an inferred approach. For example they test a drug and it helps 60% of the people it is considered a success. Engineering requires the thing you build to work 100%. This gives different ways of viewing studies.

Based on the science of the study they would have concluded my wife did not have a G-Spot. Since for 17 years I would poke a bundle of nerves and she would react, but the reaction was to tense up. She would ask me to stop when I was rubbing her G-Spot. This was not a successful stimulation of the nerves.

Now she likes the exact same bundle poked and reacts differently. This proves that mental state is also a condition of the experiment that must also be accounted for. In the case of twins the mental state can vary. So, physiology is only one component to the successful stimulation of the G-Spot.

Sounds like we all need to do more independent research, repeatedly as often as we can.

I tried to find the study. If you check the first post, you will see that I read the official abstract. I don't have a subscription to the journal in question, so I can't read the full text. The abstract gives a good overview of the methodology, enough that I feel comfortable criticizing it.

But, they *didn't* poke the nerves. They merely asked questions. I like thermight's further explanation.

The reason medicine might have to take that approach is that the human body is orders of magnitude more complex than any building.

So let's go back to the study again: it is peer reviewed, so people who have spent their entire lives studying this read it and found it to be good enough for publication, so the idea that one can simply brush it aside because of an article they read on the BBC is a bit naive.

But more important than that, it is important to understand that they are not denying that women feel something when "poked" around that region. Heck, in their own sample they reported a majority of women feeling something.

But the thing is, how do you explain that sensation? There are women who also report having orgasms through anal sex, should we create an "A" spot?

Because, as it is often said, the brain is the most powerful sex organ.

In the case of the G spot, for example, no one has ever been able to identify it anatomically or biochemically. We know the appendix exists exists not because people say they feel it, but because if you cut someone open, if you do an ultrasound, etc, you can see it there. In the case of the G spot, no one has ever found evidence of an organ separate from the extension of the clitoris there.

So this study makes perfect sense in that regard: we can't find it, so what explains the sensations? Is it the mental/environmental part of sexual arousal or an actual physical characteristic? Well, with something so far undetectable like the G spot, they relied on something that is widely used and accepted in medicine, which is twin studies. And other twin studies have found higher correlations for twins regarding clitoral orgasms and premature ejaculation, establishing a hereditary aspect to both. But there is no hereditary aspect to the g spot. Now, saying it's mental/environmental doesn't mean its fake. The study doesn't deny that women feel something, just that they found no evidence that it is a inheritable, and therefore physical, as opposed to mental, trait.

...........

I think these two points you make are the key points the discussion.

1st the brain is the key. So, much is dependent on the person and even their state of mind. Have a bad day and you can "poke" those nerves for hours and not get a pleasurable response.

2nd an extension of the clitoris. This is a key fact that I was not aware of, since I am an amateur G-spot researcher. Since, some ladies like theirs stimulated up and down, side to side, in circles or "poked" from the location commonly referred to as the G-spot. While this does not mean the existence of the location that has the potential for pleasure does not exist. It just means that it is not its own organ.


I would conclude that while the G-spot is not a unique organ it still exists.



I do have one question on the topic. Do they know where the fluid comes from when they squirt? I have heard different theories and don't know what is fact verses speculation.

That's how I interpreted the study.

"There is no physiological or physical basis for the G-spot" doesn't rule out the possibility that girls who like having their 'G-spot' stimulated aren't actually enjoying stimulation of the urethral sponge or clitoral shaft. It simply states that there is no distinct physical organ that can be identified as a G-spot.

Willravel 01-14-2010 03:58 PM

I reread the OP and I'm having a bit of trouble understanding. Science doesn't work by democracy. Asking a woman if she has a G-spot is no more scientific than Fox News asking if President Obama is a secret Muslim. There's no experimentation taking place here, it's just a census.
Quote:

The women in the study, who were all pairs of identical and non-identical twins, were asked whether they had a G-spot.

If one did exist, it would be expected that both identical twins, who have the same genes, would report having one.
They, being individuals, could interpret the same stimulation differently regardless of shared phenotype.

Here's how it should work
Is there a G-Spot?
Research, including both testimony and experimentation
Construct a hypothesis
Test the hypothesis directly with experimentation
Analyze the results

Until this is done, there cannot be any scientific conclusion presented.

Martian 01-14-2010 04:39 PM

Sigh.

Everyone seems to be getting caught up on the self-reporting aspect. Do you really think the researchers fingerbanging 1800 women would've affected the outcome in any significant way?

A lab setting or office setting is not conducive to relaxation. If relaxation is required for a woman to identify G-spot stimulation, then it's highly unlikely the scientists actually would've gotten anything. If the ladies didn't find it on their own, it wasn't going to be found during the study.

There have been studies in the past to find a physical structure that could be identified as the G-spot. They turned up nil. This study was based on heritability, and it demonstrated no correlation. It was perfectly valid, from a scientific standpoint.

Obviously, the researchers needed to take each of the 1800 women out for a fun date, give them roses, split some champagne, get to know them, make them feel listened-to and adored, share some secrets over a digestif and a little chocolate dessert, go back to their place for some more intimate talk, a candlelight massage, and then fingerbang them to check for g-spot.

What is science coming to when that is too much to ask?

Finger-banging? Probably not, but thin again I'm not a researcher so I'm not qualified to answer. I'm not a biologist and even I'm aware there there's been testing and experimentation on the female sexual response, with results that aren't just verifiable, but predictive. We have information on everything from nervous response being higher towards the surface of the vaginal cavity than the inside to what specific chemicals are released during the female orgasm. If researchers are so impotent when it comes to testing of female sexual response, how can we have such information?

These are baseless assumptions without evidence. Can you demonstrate that women are less likely to have a g-spot orgasm in a laboratory setting by citing data or studies? Science doesn't work on assumptions because we as humans are fallible, we introduce bias and mistakes.

Why are self reported studies less scientific? The notion that "science" only happens in lab settings with controlled experiments is completely naive.

Self reporting is the basis of a significant part of modern medicine, and the entire basis for most research regarding mental health, pain, and, yes, sex.

And keep in mind that no study is ever intended to be the final word on anything. The fact that a study is not the absolute most perfect study ever does not preclude it from being valid and making a contribution.

Science isn't as objective as you might think. But that aside, most biases in self reported studies end up as statistical "noise," as we really have no reason to expect that personal biases in self reporting any issue will all go in the same direction.

Also, the idea of an objective measure of sexual pleasure seems a bit like an oxymoron.

There are many instances where biases in self reported studies would mostly go in one direction. For instance, women who have children with birth defects are more likely to report that they were exposed to chemicals during their pregnancies than women whose children were born without birth defects. There is also the classic example of polls over-estimating support for minority candidates because poll takers don't want to seem racist.

That's why it would be nice to see the actual study- you've got access dippin, don't you? A quote from one of the researchers showed that they were at least aware of the considerable pressure a woman may be under to conjure up a g-spot she may or may not actually have. It would be informative to see how the researchers dealt with this potential source of bias in their survey. It might also be informative to see how the prevalence of g-spots reported by the participants compares to g-spot prevalence reported in other studies.

Just for the record, one of the reasons I can't wait to get started in grad school is that I will get access to pubmed back.

Fair enough.

These are all necessarily abstracts; I am neither a medical practitioner nor a student, and therefore do not have access to anything more detailed.

Here's a study from 2009, demonstrating via sonography the relationship between the clitoris and the anterior wall of the vagina. Specifically, it notes that a likely cause of 'G-spot' stimulation is contractions of the anterior vaginal wall stimulating the clitoral shaft:

The clitoral complex: a dynamic sonographic study. [J Sex Med. 2009] - PubMed result

Here's one that found an increase in nerve density about two fifths of the way into the vagina. Sample size: 7 cadavers, all Korean.

Innervation of vagina: microdissection and immunoh... [J Sex Marital Ther. 2009] - PubMed result

From 2008, this article notes a direct correlation between the thickness of the urethrovaginal wall and propensity toward vaginal orgasm, but again identifies no discrete and/or distinct 'G-spot' structure.

Measurement of the thickness of the urethrovaginal... [J Sex Med. 2008] - PubMed result

This one found the entire anterior vaginal wall to be sensitive, with no specific area of increased sensitivity (ie, no 'G-spot'). Sadly, there's no mention of methodology in the abstract, so you'll have to take on faith that their study was sound:

Vaginal erotic sensitivity by sexological examinat... [Acta Obstet Gynecol Scand. 1986] - PubMed result

And an article from the Journal of Sex and Marital Therapy, summarizing previous information. Again, sadly only an abstract, but it plainly states that although there's clearly a basis for tactile stimulation of the anterior vaginal wall leading to orgasm and even female ejaculation, there's no discrete physical structure known to be the cause of it:

The "G spot" and "female ejaculation": a current a... [J Sex Marital Ther. 1986] - PubMed result

You'll note that a few of these articles do note a relationship between the clitoral shaft and/or root and the anterior vaginal wall, but there's only one that indicates anything that could be remotely considered evidence for a discrete 'G-spot' structure. As for that one -- well, I'm certainly not an expert, but I'm not sure that 5 out of 7 is statistically valid.

But when there is systematic bias like that, that becomes an included variable, and tests on omitted variables turn significant.

I'm not saying self reported studies are perfect, just that they are informative and that there are several known ways to deal with the most obvious statistical issues.

Regarding the issue you mentioned, they include a number of variables in the study, some related to individual experience, some to the so called "measurement error" and that is how the eliminate the "genetic" aspect of it all. For some bias to explain the insignificance of genetic factors in a multivariate study like this, the bias would have to be one that is extremely high correlated with experience and uncorrelated with genetics. Is it possible to have something like that? Sure, but that is why we have significance levels in statistics.

Ideally it becomes an included variable, and you'd expect that such things would be accounted for, but you can't really tell unless you read the actual study.

I'm not saying that I necessarily disagree with their analysis and results. I do think that the abstract doesn't do much to provide support for their conclusion and without reading the study I can't tell whether the study actually supports their conclusion.

*edit because I responded before your third paragraph made it in*

From a completely anecdotal standpoint, I think that sexuality is sufficiently complicated that experience might play an an equally significant or greater role than genetics.

Except that 'science' has never said anything of the sort:

Quote:

According to 20th century folklore, the laws of aerodynamics prove that the bumblebee should be incapable of flight, as it does not have the capacity (in terms of wing size or beats per second) to achieve flight with the degree of wing loading necessary. Not being aware of scientists "proving" it cannot fly, the bumblebee succeeds under "the power of its own ignorance". The origin of this myth has been difficult to pin down with any certainty. John McMasters recounted an anecdote about an unnamed Swiss aerodynamicist at a dinner party who performed some rough calculations and concluded, presumably in jest, that according to the equations, bumblebees cannot fly. In later years McMasters has backed away from this origin, suggesting that there could be multiple sources, and that the earliest he has found was a reference in the 1934 French book Le vol des insectes; they had applied the equations of air resistance to insects and found that their flight was impossible, but that "One shouldn't be surprised that the results of the calculations don't square with reality".
Further to that, science would never actually say anything of that nature -- that's not how scientists do their job. The most that one might say in that regard is that 'we don't yet understand the mechanism used by bumblebees to achieve flight.'

This is actually quite relevant to the discussion at hand. It's important to keep in mind that the researchers did not claim that women aren't able to orgasm from stimulation of the anterior vaginal wall. All this study is doing is trying to determine the basis of a demonstrated effect.

I don't understand why everyone is so up in arms about this.

filtherton 01-15-2010 08:55 PM

I imagine that everyone is up in arms because the researchers decided to proclaim that they believe that the g-spot doesn't exist (at least according to the BBC) and this proclamation runs counter to many folks' firsthand (heh) experience.

There are plastic surgeons all across the US that do something called a clitoral enlargement. The method of this procedure goes something like this: locate the clitoris, stimulate the clitoris until it becomes engorged and emerges from under the hood, and inject the clitoris with testosterone. In order for this procedure to work, the surgeon has to stimulate a woman and evoke a sexual physical response. In a clinic or hospital environment. It's not just an accentual sexual response like what may occasionally happen with pelvic exams, it's a necessary part of the procedure.

If a plastic surgeon can consistently elicit a natural physical sexual response, why can't a (likely better trained) researcher?

Whoa, whoa, whoa, who said anything about a structure? The "spot" in g-spot suggests location, not structure. If there's a specific location within the vagina (a little bit in, on the roof) which when stimulated triggers the sexual response associated with g-spot stimulation/orgasms, that's the g-spot. I don't know of anyone that's suggesting there's some g-spot organ or something. I certainly wasn't arguing that, in fact above I very specifically said that it was internal clitoral stimulation. That doesn't mean there's no g-spot, though.

My interpretation is "Gee, that spot feels good".

Engorgement of the clitoris is an involuntary response that's highly similar to a male erection. It's entirely dissimilar to a subjective report of pleasure.

There's no objective way to measure whether or not something 'feels good.' This is apples and oranges, to use the colloquialism.

All emphasis mine, natch.

Did you not fully read what I wrote the first time?

The scope of the study linked in the first page related solely to the G-spot as a distinct physical entity. If the 'G-spot' is really a term for indirect stimulation of the clitoral shaft/root, then it would not be inaccurate from a biological perspective to say that the G-spot doesn't exist. It may exist as a euphemism, or as a psychological phenomenon, but neither of these has any place in a study to determine the biological basis of it, and the study in question makes no claims whatsoever regarding either.

EDIT -

Okay, I suppose that's fair.

Allow me to respond with a multiple choice question.

You read a headline in a newspaper, online, or posted on Facebook/Reddit/a discussion forum. You dislike the headline. Perhaps you believe it to be an outright fabrication. Do you:

A) Discount the headline, perhaps noting the journalistic propensity towards sensationalism over accuracy;
B) Read the article and then independently research the issue to determine the accuracy of the headline's claims; or
C) Call the headline's sources frauds, ignorant pseudoscientists and all-around meanies without doing any of the above?

I know what my answer is.

filtherton 01-16-2010 01:39 AM

I don't want to turn this into a long drawn out discussion. The BBC article is problematic because the claims made in the abstract are much tighter than the claims made in the article.

It's one thing to say "We didn't find any evidence that g-spots are heritable." This is what the abstract says. It's another thing entirely to say "We didn't find any evidence that g-spots are heritable, therefore they do not exist." This is what the researcher quoted in the article seems to think.

I think that the responses in this thread are probably fairly typical of the types of concerns people have when they are: unfamiliar with the ins and outs of clinical research methods; butting up against clinical research results (as reported in the BBC article)which seems to directly contradict their own experiences. They should be skeptical-- it's the appropriate course of action given the circumstances.

Unfortunately, the scientific community does a pretty shitty job getting actual research into regular folks' hands, so people are left to muddle around with a shitty BBC article and a short-on-detail abstract.

filtherton 03-06-2010 01:44 PM

After reading the study, I don't really see any problems of it, though many of the statistical aspects went over my head. The only really issue I have is that the heritability argument doesn't seem sufficient to me to proclaim that the g-spot doesn't exist, it just places more emphasis on nongenetic factors.

Sci has constantly been annoyed that no one seems to have performed a real, thorough study on the sensitivity of the vagina. Or at least, it's beyond her pubmed-fu. If someone has done it, please let me know! I'd really like to cover it and I'm very annoyed that I cannot seem to find it. Sci is also annoyed by this because several studies have covered the sensitivity of the penis. It's just not fair.

But today, Sci was pubmedding furiously, and she FOUND SOMETHING. I am so excited.

ResearchBlogging.org Foldes and Buisson. "The Clitoral Complex: A Dynamic Sonographic Study" Journal of Sexual Medicine, 2009.

YES! Not the whole thing, but it's a start.

http://scienceblogs.com/neurotopia/woohoo.jpg

I suppose you could say the pictures below are NFSW. But they're sonograms. So it could be anything, really, and most people won't know. If your boss comes up behind you, tell them you're looking at someone's baby pics.

Alright, so here we go. What this study was really after was not vaginal, or even clitoral sensitivity. What this study was after was the G-spot. As you might be aware, there is some controversy as to whether or not the G-spot actually exists, and if it does, what it consists of. For example, is there really a difference between clitoral and vaginal orgasm, and what causes the difference?

To look into this further, let's look at some anatomy:

http://scienceblogs.com/neurotopia/c...%20anatomy.png

You can see above the basic anatomy of the clitoris and the vaginal opening below it. You can see that the clitoris has a glans and a cavernous body, which is located on either side of the urethra. Keep in mind that the root of the clitoris extends pretty far in, and comes rather close to the anterior (that's the front) wall of the vagina.

My my...isn't that similar...

http://scienceblogs.com/neurotopia/penis-anatomy.jpg

Indeed.

The female clitoris and the male penis are really quite similar in anatomy. So the reasoning behind this paper was this: why aren't all women capable of having a vaginal orgasm if they have the equivalent of a penis? Perhaps it has something to do with the relationship between the clitoris and the vagina.

To look at the relationship between the clitoris and the vagina, they took women (age matched), and checked out the clitoris. They did this both at rest and when the women were performing perineal contraction (that's a Kegel). Their underlying hypothesis was this: if the clitoris comes really close to the vagina, perhaps the clitoris plays the underlying role in vaginal orgasms.

And here's what they got:

http://scienceblogs.com/neurotopia/c...20anatomy2.png

What you can see here is the sonogram image, aligned like the model above. The glans is at the top, the cavernous bodies (clitoral bodies) are on the sides, vagina is at the bottom.

http://scienceblogs.com/neurotopia/c...20anatomy3.png

This is a slightly different angle. Here you're looking at the cavernous bodies of the clitoris on the sides, with the top of the body above and the bottom below (like you're viewing up someone's vagina if they were at the gynecologist). What you can also see is a change resulting from the contraction of the perineum. In the contraction (on the right), the cavernous bodies are brought downward and the angle is decreased, bringing them closer to the anterior wall of the vagina.

http://scienceblogs.com/neurotopia/c...20anatomy4.png

And what you can see here is a midsagittal section, with the woman lying on her back, and the entrance to the vagina in the air (which is odd and I think due to an extreme pelvic tilt). You can see that the root of the vagina is closely located to the anterior vaginal wall.

They then had the patient locate the area of most sensitivity with their own fingers, and took an ultrasound that way. Invariably (though it was n=5), the women poked at the area closest to the clitoral root. When she then contracted her perineum, the clitoris moved closer to the area of the anterior wall she was pointing to.

So what's the conclusion? The authors conclude that women may be able to achieve vaginal orgasm via stimulation of the G-spot because the highly innervated clitoris is pulled closely to the anterior wall of the vagina. This is cool because this means there's no need for some special region of nerves to create a G-spot, it could, rather, just be an association of anatomy.

Sci does have some issues with this paper, though.

1) n=5? We can so do better.

2) All of the women apparently were able to locate their own g-spots successfully. It would be very interesting to see this done in women who do not think they have a g-spot or don't know where it is, and see where they point to when asked for the most sensitive spot.

3) Sci has issues with the fundamental question of why not all women can have a vaginal orgasm if they have the anatomical equivalent of a penis. My problem is this: a clitoris may be the anatomical equivalent of a penis. The VAGINA isn't. So perhaps a clitoral orgasm (of which almost every woman is capable unless there are underlying problems) is the equivalent of the male orgasm, while the vaginal orgasm is something else, if it IS something else, and related more of the positioning of the clitoris relative to the vagina?

In conlusion: Moar studies, pleez! :)

Friday Weird Science: FINALLY, a clitoris study! : Neurotopia

It's a blog review of one of the articles Martian posted that has some interesting implications. First if the G-spot is an association of anatomy, it would be unsurprising then, given the variable nature of reproductive anatomy, that there are varied reports amongst women. It also accounts for the initial study's (that was quoted in the OP) inability to locate the g-spot based on self reporting. The self reporting was accurate but due to the nature of the anatomy it both existed and did not exist in the people who said it did, which understandably did not cross the minds of the researchers in the study. Right data, wrong conclusion, which is why interpretation is important.

The idea here also explains why there is such variability among the women who report having a g-spot. Everything from 'meh, it's there" to "ZOMG GREATEST THING EVER". One potential shortcoming is the inability to then explain the account of g-spot orgasm being different from clitoral orgasm, as it would be the same organ causing both.

Next round of studies: Can we induce a g-spot response in women who claim to not have it by artificially narrowing the wall of the vagina between the vaginal cavity and the base of the glans?

Scientific method refers to a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. To be termed scientific, a method of inquiry must be based on gathering observable, empirical and measurable evidence subject to specific principles of reasoning. A scientific method consists of the collection of data through observation and experimentation, and the formulation and testing of hypotheses.


Statistical survey, a method for collecting quantitative information about items in a population.

Which description better fits?

Yeah, it's in a few ways, and somewhere up on the roof.
It's a pleasant (drifting & sometimes elusive) intensifier for an orgasm,
less so than prostate stimulation. (past life memories)

Dr. Safelove 07-03-2010 08:22 PM

Sexually active physician's perspective on G-spot: research is ridiculous
 
This whole controversy is ridiculous. Every female who has experienced pleasurable sensations (and especially orgasm) from sexual positions like doggy style, which do not directly stimulate the clitoris; every female who has ever experienced pleasure through digital stroking of the front wall of her vagina, by herself, her partner, or a dildo; every male who has inserted a finger or two and stroked this area of the vagina as it becomes engorged and protrudes from the rest of the vaginal wall; all these have confirmed the existence of what may be called the G-spot. Since women have been given inconsistent information, asking them if they have a G-spot is stupid research. Asking if they are aware of a sensitive area in that area of the vagina would be better, but of course not all have discovered it.

There is an area not too deep inside the front wall of the vagina, with glands and sensitive nerve tissue, which becomes engorged (even larger than the clit in many women, so calling it a "spot" is not accurate or helpful) during sexual stimulation, and becomes highly sexually sensitive. Its nerves must be connected to the same nerves as serve the clitoris, because all orgasms feel similar and cause the same physiological results, like muscular contractions of the vaginal wall and subsequent resolution of congestion.

And the interesting thing is that not only have most sexually aware human females been aware of this physiology for thousands of years before it had a name, thousands of other species that have intercourse from the rear know about it too. Only stupid human researchers have any doubt!

This is my first post so go easy on me please.

I have always loved to experiment sexually and find my chances of enjoying sex are massively limited if I don't feel like my partner (whoever that may be at any particular time) is enjoying it, and I mean really enjoying it. Because of this I prefer to perform oral than have it performed on me or to use my hands rather than have hands used on me, it's just the way I am. Anyway, after a past I'm not overly proud of involving 100's of sexual partners of different shapes and sizes (some which do not bear thinking about in the cold light of day) and a 5 yr marriage which ended when my wife died last year, I know that I've had more sex than most 30 yr olds I'm totally relaxed about it and I've never had any complaints lol.

Anyway to cut a long story short I read all about finding the g-spot years ago and it was never obvious to me what it was by feeling it but some girls have reacted to the 'come hither' motion, some by needing a 'wee' which subsides when I reduce pressure or speed and some who totally lose it maybe squirting a bit but the vast majority seem far more sensitive to clitoral stimulation. However a few weeks ago I met a girl who proved to me beyond all doubt the existence of a g-spot. Funnily enough the first thing I noticed was how hard her clit was to find and how she hardly seemed to react when I played with it but when I went for a bit of the old 'come hither' there is a hard wet lump almost like a hard rubber nose the size of a big toe and when I touch it either at the same time as her clit or nipples she goes absolutely wild and has massive full body orgasms that last for ages and squirts like I've only seen in porn. It is absolutely amazing and absolutely massive. Categorically the g-spot does exist!
