Different areas of women's brains affected during sex

Women may be able to fool their partners by faking an orgasm but a brain scanner will catch them out every time, a conference heard on Monday.

Researchers at the University of Groningen in the Netherlands have used scans to show that different areas of the brain are stimulated during an orgasm but are not activated when a woman fakes it.

“Women can imitate orgasm quite well,” Gert Holstege told a fertility meeting on Monday. “But there is nothing really happening in the brain.”

He and colleagues took brain scans of 13 women and 11 men, aged 19-49 who had volunteered for the study, while they were being sexually stimulated by their partner and during an orgasm and compared them to images of their brains at rest.

“We wanted to know what the brain was doing during orgasm,” Holstege said.

When women genuinely achieved an orgasm, areas of the brain involved in fear and emotion were deactivated. Those areas stayed alert however when women were faking it.

The researchers also found that the cortex, which is linked with consciousness, is active during a fake orgasm but not during the real thing.

“The deactivation of these very important parts of the brain might be the most important thing necessary to have an orgasm,” said Holstege.

“It means that if you are fearful or at a very high level of anxiety, then it is very difficult to have sex because you really have to let yourself go,” he added.

Male brains affected differently
The brain scans for men during orgasm were less conclusive, according to Holstege.

But they did show that different parts of the male and female brain are activated and deactivated during sexual stimulation.

The researchers found less deactivation in the males in the areas of the brain linked to emotion and fear when they were sexually stimulated.

They are now planning further studies to compared the male and female brains during orgasm.

About 5,300 delegates are attending the 4-day meeting of the European Society of Human Reproduction and Embryology

For women, it seems, sex is a big turn-off, reveals a brain scanning study. It shows that many areas of the brain switch off during the female orgasm - including those involved with emotion.

“At the moment of orgasm, women do not have any emotional feelings,” says Gert Holstege of the University of Groningen in the Netherlands.

His team recruited 13 healthy heterosexual women and their partners. The women were asked to lie with their heads in a PET scanner while the team compared their brain activity in four states: simply resting, faking an orgasm, having their clitoris stimulated by their partner’s fingers, and clitoral stimulation to the point of orgasm.

The results of the study are striking. As the women were stimulated, activity rose in one sensory part of the brain, called the primary somatosensory cortex, but fell in the amygdala and hippocampus, areas involved in alertness and anxiety. During orgasm, activity fell in many more areas of the brain, including the prefrontal cortex, compared with the resting state, Holstege told a meeting of the European Society for Human Reproduction and Development in Copenhagen on Monday.

In one sense the findings appear to confirm what is already known, that women cannot enjoy sex unless they are relaxed and free from worries and distractions. "Fear and anxiety levels have to go down for orgasm. Everyone knows this but we can see it happening in the brain," he explains.
Extraordinary behaviour

From an evolutionary point of view, it could be that the brain switches off the emotions during sex because at such times the chance to produce offspring becomes more important than the survival risk to the individual. Holstege points to the extraordinary behaviour seen in some animals during the breeding season, such as March hares, when the urge to mate seems to override the usual fear of predators.

But Holstege cannot explain why there is such extreme deactivation in so many areas of the brain during orgasm. Only one small part of the brain, in the cerebellum, was more active during female orgasm. The cerebellum is normally associated with coordinating movement, though there is also some evidence that it helps regulate emotions. “We don’t know what activation of the cerebellum corresponds to,” Holstege admits.

His study also revealed clear differences when women were faking an orgasm. Part of the brain involved controlling conscious movement lit up, and there was none of the extreme deactivation.

Next the team hope to look at what happens to the brain in the minutes after orgasm, as well as in patients with sexual problems. The team has already done a similar study involving 11 men, which revealed far less deactivation during orgasm than in women. However, Holstege says the results are probably unreliable and need to be repeated. The problem is that PET scanners measure activity over two minutes -

and in men it is all over in a few seconds.

Gayle, could be in the genes:
Is this the ultimate excuse for poor performance in bed? “Sorry, darling,” the man says, just before falling asleep. “It’s your genes.”

According to a study published this week, up to 45% of the differences between women in their ability to reach orgasm can be explained by their genes. Despite decades of surveys and conjecture about the role of culture, upbringing and biology in female sexual function, from Freud in 1905 to the Hite report in 1976, this is the first study of the role of a woman’s genes.

Its findings suggest there is an underlying biological basis to a woman’s ability to achieve orgasm. Whether that basis is anatomical, physiological or psychological remains uncertain, says Tim Spector of the twin research unit at St Thomas’ Hospital in London, UK, who carried out the study.

“But it is saying that it is not purely cultural, or due to peer pressure, or to differences in upbringing or religion,” he says. “There are wide differences between women and a lot of these differences are due to genes.”
Mixed results

Spector’s team asked more than 6000 female twins to fill out a confidential questionnaire about how often they achieved orgasm during intercourse and masturbation. They received 4037 complete replies, which included answers from 683 pairs of non-identical twins and 714 pairs of identical twins. The women’s ages ranged from 19 to 83, and about 3% were lesbian or bisexual.

Only 14% of the women reported always experiencing orgasm during intercourse. Another 32% of the women reported that they were unable to achieve orgasm more than a quarter of the time, while 16% never achieved it at all. Comparing the results from identical and non-identical twins suggests that 34% of this variation in ability to orgasm during intercourse is genetic.

The idea behind twin studies is that pairs of twins grow up in similar environments. So if identical twins are more similar in some way than non-identical twins, then that similarity must be down to their identical genes rather than the environment.

Unsurprisingly, more women were able to achieve orgasm through masturbation, with 34% saying they could always do so. However, the figure for those who could never achieve it was only slightly lower, at 14%. The analysis suggests that 45% of this variation is genetic.
Men cleared

Spector says he was surprised by the similarity in the numbers of women unable to experience orgasm either through intercourse or masturbation. “With masturbation there are fewer external factors – i.e. men,” he says. “So the higher heritability value for masturbation gives us a clearer picture of what’s going on.”

The discovery of a genetic basis for the ability of women to orgasm raises questions about its evolution. One theory is that it is a tool for mate selection, the idea being that males best able to bring females to orgasm are also the best males to help raise children. Another is that the female orgasm produces movements that increase sperm uptake, and therefore fertility.

But studies of other primates suggest otherwise. Female stump-tailed macaques have orgasms too – but mainly during female-female mountings, which hardly supports the fertility or mate-selection idea.

Bonobos engage in highly promiscuous sex and mutual masturbation, complete with orgasms, a practice that is thought to promote group cohesion. This supports yet another theory: that orgasm is important in bonding.
Accidental echo

But even if orgasm does play this role, it cannot be crucial in humans. The finding that many women cannot achieve orgasm because they do not have the genes for it shows that the ability to orgasm is not a trait for which there has been strong evolutionary selection, says Elisabeth Lloyd of Indiana University in Bloomington, author of The Case of the Female Orgasm. This supports her theory that as far as orgasms are concerned, women have been riding on the genetic coat-tails of male evolution, and that the female orgasm is merely an accidental echo of the male one, the equivalent of male nipples.

Lloyd says the findings also challenge the notion that the failure to achieve orgasm represents “female sexual dysfunction”, an idea popular with companies keen to sell remedies for this so-called disorder. “What definition of ‘normal’ could possibly justify labelling a third of women as ‘abnormal’?” she asks.

Even if struggling to achieve orgasm is nothing unusual, Spector says it might be possible to find ways to make it easier. Though hundreds of genes could be involved, “that doesn’t mean we couldn’t find the genes and pathways, if this was taken more seriously as a problem”, he says.

See, it ain't the fault of us guys.....and in my next life, I might come back as a Bonobo

I'd find it impossible to believe since my adult life change that I ever missed recognizing a fake cuz frankly, being in the throws of a real one can't be mistaken from anything else. I'd never tell someone that they'd faked though, it would most likely cost the next real one with that lil' gem, and soon or later, the real one will hit, even with the timid ones it just takes intricate attention and an unselfish interest...sid~~~faked upon of course and yet the real ones w-a-a-a-y make up for all the duds

Like the lady said,"Just because I don't get the brass ring,dosen't mean I don't like to ride the merry go round" They could have saved a lot of money,because women having a real orgasm, an out of sight face twisting knuckle biter, cannot inhale.

LOL, I can imagine that is the ultimate rejection when an inanimate object rejects you. I've had enough rejection in my life, I'm so glad I don't have to worry about that one. The worse part I suppose is it doesn't do you any good to beg an electronic device; sometimes it works to beg a wife.
