For almost a decade, researchers at Pfizer struggled to show that Viagra, the male impotence drug, could enhance sexual function in women. Countless tests on thousands of women made it clear that the little blue pill, though able to stir arousal, did not always evoke sexual desire. Viagra's failure underscored the obvious: when it comes to sexuality, men and women to some extent are differently tuned. For men, arousal and desire are often intertwined, while for women, the two are frequently distinct. Scientists have recently begun to map out how this difference shows up in the brain.

For almost a decade, researchers at Pfizer struggled to show that Viagra, the male impotence drug, could enhance sexual function in women.

Countless tests on thousands of women made it clear that the little blue pill, though able to stir arousal, did not always evoke sexual desire. Viagra's failure underscored the obvious: when it comes to sexuality, men and women to some extent are differently tuned. For men, arousal and desire are often intertwined, while for women, the two are frequently distinct. Scientists have recently begun to map out how this difference shows up in the brain.

For example, male arousal, studies find, is strongly visual, and when men engage in sexual activity or even anticipate it, brain structures once thought to have little connection to sex spring into action. The same brain regions, however, remain relatively quiet when women are aroused.

At the core of the sexual divide, some researchers say, is the amygdala, an almond-shaped nugget embedded in the limbic system, the brain's seat of emotions.

Once thought to be involved exclusively with emotions like fear and anger, the amygdala is now believed to be more complicated. In one recent study, a team of researchers at Emory University had 28 men and women look at erotic photographs while an M. A pattern immediately emerged. The photographs set off a frenzy of brain activity, particularly in the amygdalae of men. Yet the two groups reported equal arousal most of the time.

Stephan Hamann, a professor of psychology and the lead author of the study, which was published online by Nature Neuroscience last week and is scheduled to appear in the journal in April. Much of the insight into the amygdala's role in anticipating sex, and possibly other pleasant emotions, stems from research on animals.

In a study in , scientists trained caged male rats to gain access to females by pushing a lever. The researchers then destroyed part of the amygdala. The rats lost interest in pressing the lever. Yet despite this lack of motivation, they had no problem engaging in sexual intercourse when the females were placed in their cages.

Other studies have gone further. In a study published last year, researchers in the Netherlands recorded brain activity in men as their female partners brought them to orgasm. The amygdala, the scientists found, showed decreased activity during climax. Other studies have suggested that a larger amygdala may lead to a more robust sex drive. Hamann pointed out that the amygdala is known to have intricate connections to primates' visual systems.

One reason for the powerful response to visual stimuli in men, he said, could be cultural. Men tend to be inundated with sexual imagery and, possibly, are more likely to seek it out. Evolution may also have a role. Some experts argue that, over time, men naturally became more dependent than women on sight in selecting a mate.

Fisher has studied the brains of people in the early stages of romance. For a man, she found, pictures of a new partner light up parts of the brain involved in visual processing and arousal.

But women, she noticed, show more activity in areas linked to reward, emotion and attention. Fisher said. Women, on the other hand, may be more attuned to the signs that a man will make a good father or provider, she added, though some other researchers find this assertion dubious.

A woman's choice of a mate, Dr. Fisher argues, could involve an interplay among a number of factors, including, some experts now theorize, a man's odor. Several years ago, Swiss scientists discovered that women could sniff out genetic differences in potential mates.

When women were asked to smell T-shirts that different men had worn, they often ranked more favorably the shirts that belonged to men with dissimilar genes for major histocompatibility complex, a group of proteins involved in immunity to disease. The odors a woman preferred also tended to remind her of past and current partners. Seeking out different immune-system genes might be a way to prevent inbreeding or to arm offspring with a more versatile immune system, said Dr.

Rachel S. Herz, a psychologist at Brown who in a study in found that women ranked body odor above almost every other factor in attraction, except ''pleasantness. Herz said. And what is indicative of how healthy you are is your immune system, which is manifested in your smell. Yet to play down the role of visual stimulation for women would be unwise, researchers say, and female admirers of Brad Pitt or George Clooney would probably agree. In research last year at Northwestern, Dr.

Meredith Chivers, demonstrated that women could sometimes have more powerful responses to visual stimuli than men, although in different ways. In her study, which ignited a small firestorm, Dr. Chivers used a device to measure genital arousal in subjects as they looked at pornography.

Heterosexual men, she found, were aroused by footage of men and women having sex. Gay men reacted to two men having sex. Women, regardless of sexual orientation, responded to everything. In some cases, she said, women reported no sexual arousal, though the device said otherwise. What is apparently a disconnection between female arousal and desire, researchers note, squares nicely with the Pfizer findings on Viagra. Still, other experts point out that it is impossible to define neatly or predict how men and women will respond.

People's perceptions are colored by their personal experiences, said Dr. Leonore Tiefer, a sex therapist who is a clinical associate professor of psychiatry at the New York University medical school. Tiefer said. It is not the case that every person pays attention to the same thing. The whole experience is shaped by your history and by what you're paying attention to. Last month, they gave up.

Sex is all in our heads, quite literally. Our brains are involved in all steps of sexual behavior and in all its variations, from feelings of sexual desire and partner choice, to arousal, orgasm and even post-coital cuddling. Now, with hundreds of neuroimaging studies on human sexual behavior, results from these studies are finally being integrated for meta-analysis, allowing for improved precision in identifying activated brain areas.

While what a person finds sexy is often a very personal thing, research has shown that there can, in many ways, be specific types of turn ons for men and women. Biology may play a role in this, of course. These are signs a person is, in fact, turned on. And again, several things can get them there.

Miss Annabelle – Visual Stimulation. How Men and Women See Things Differently!

Arousal is the state of being awake and focused on a certain stimulus. For individuals who have a vagina, this involves a number of physiological changes in the body. According to the Cleveland Clinic , desire disorders involve a lack of sexual desire or interest in sex, while arousal disorders involve wanting sex but struggling to get your body in the mood. The sexual excitement stage — also known as the arousal stage — involves a range of physiological changes in the body. Most of these functions prepare the body for vaginal intercourse. For example, your vagina becomes more wet because the glands produce lubricating fluids. Your clitoris and vulva swell up as your blood vessels dilate. Your nipples might become more sensitive to touch, too. The plateau stage is the period before orgasm.

How Do Men and Women Differ in How They View Sex?

Sexual stimulation is any stimulus including bodily contact that leads to, enhances and maintains sexual arousal , and may lead to orgasm. Although sexual arousal may arise without physical stimulation , achieving orgasm usually requires physical sexual stimulation. The term sexual stimulation often implies stimulation of the genitals , but may also include stimulation of other areas of the body, stimulation of the senses such as sight or hearing and mental stimulation i. Sufficient stimulation of the penis in males and the clitoris in females usually results in an orgasm.

We believe that sex is a beautiful, God-given desire that can bring a husband and wife together in oneness. We also believe sex is a thermometer that measures the depth of the relationship—its presence or absence often indicates the level of commitment and intimacy in other areas of your marriage.

The magazine Playgirl famously launched as a source of sexual imagery targeted at presumably heterosexual women. It just as famously ended up with a readership of mostly homosexual men. The issue with such studies is the social and cultural baggage about sex and desire that women likely bring into a controlled laboratory environment. With the goal of stripping away that baggage and focusing only on a biological response, a research group has collected and processed brain-imaging findings from 61 relevant studies, producing a result likely to generate some controversy. His team sought to look more holistically at brain networks that respond to visual sexual stimuli while excluding influences such as touch.

The paper, just published in the Proceedings of the National Academy of Sciences journal, analyzed 61 past scientific studies that in total collected data on nearly 2, adults of different sexual orientations. Each study conducted virtually the exact same experiment: They showed men and women a series of erotic images and videos while their brains were hooked up to an fMRI machine. These neuroimaging scans showed the various regions of the brain that were activated in response to the visual stimuli, including the "insula, middle and inferior occipital and fusiform gyrus, amygdala, caudate, claustrum, globus pallidus, pulvinar, and substantia nigra. The biggest factor that affected how much of a person's brain got activated? The particular type of sexual content they viewed. The least predictive factor? Just for good measure, the researchers decided to specifically analyze two particular regions of the brain: gray matter volume in the right insula and the anterior cingulate gyrus, two areas that past research has shown are associated with sexual desire in women.

May 20, - Gender difference in brain activation to audio-visual sexual stimulation; do women and men experience the same level of arousal in response.

The emotion control center of the brain, the amygdala, shows significantly higher levels of activation in males viewing sexual visual stimuli than females viewing the same images, according to a Center for Behavioral Neuroscience study led by Emory University psychologists Stephan Hamann and Kim Wallen. The finding, which appears in the April edition of "Nature Neuroscience," demonstrates how men and women process visual sexual stimuli differently, and it may explain gender variations in reproductive behavior. The study adds to a growing body of research in animals and humans that indicates the amygdala plays a central role in male sexual behavior, Hamann says. In addition to adding to basic neuroscience knowledge, the findings potentially could have applications that could help scientists develop therapeutic measures to help people overcome sexual addictions and other dysfunctions, he says. In the study, 14 male and 14 female participants viewed several types of sexual and social interaction images for 30 minutes.

When It Comes to Sex, Men are Visual and Women are Emotional

We receive thousands of visual cues and images daily, from the latest vine video to smiles from friends, sight is a commanding sense! It only follows that visual stimulus can play a huge part in our sexuality and sex lives as well. There is a billion dollar industry built on the visual aspect of sex and business is booming! From advertisements to lingerie, visual sexiness is top on the list.
