    Sharing personal information brings people closer together. Verified by Psychology Today. Bryant Furlow, published March 1, - last reviewed on June 9, How do we humans announce, and excite, sexual availability? Many animals do it with their own biochemical bouquets known as pheromones. He came to believe that natural selection designed animals to produce two, and only two, types of odors—defensive ones, like the skunk's, and scents for territorial marking and mate attracting, like that exuded by the male musk deer and bottled by perfumers everywhere.

    Smell evaluative sniffing that mammals engage in during courtship were clues that scent is the chemical equivalent of the peacock's plumage or the nightingale's song—finery with which to attract mates. In the following century, a rich array of animal pheromones were documented for seals, boars, rodents, and all manner of other critters. But not for human beings. Some of Darwin's contemporaries embraced human uniqueness in this regard as evidence of our inevitable ascendance, as if Nature's Plan somehow called for the evolution of a nearly naked two-legged primate with a poor sense of smell to conquer the Earth.

    The French physician Paul Broca—noting that primates' social olfactory abilities are diminished compared to those of other mammals—asserted that monkeys, apes, and humans represent ascending steps from four-legged sniffing beasts to sight-oriented bipeds. Monkeys, he argued, have smaller "smell brains" than other mammals, and apes' brains are even smaller than that. Among humans, only the tribal "primitives," Broca wrote, could still attach erotic import to the bodily smells of man.

    More enlightened researchers dismissed such views as racist tripe. But they still noted that humans engage in very little scent-driven socializing—compared to, say, the urine-washing displays of monkeys during which urine is rubbed on the feet to attract mates.

    To smell matters worse, humans seemed to lack the hardware sex communicating by scent. Pheromone reception in other species is the business of two little pits one in each nostril known collectively as the vomeronasal organ VNO.

    Few scientists of the time claimed to have been sex to locate a human VNO. Those who did complained that the VNO is so small that they could detect it only rarely. But most scientists, without bothering to look, simply dismissed the idea of a VNO in humans. It's been scientific dogma for most sex this century that humans do not rely on scent to any appreciable degree, and that any VNOs found are vestigial throwbacks. Smell, in the s, physiologists declared that humans lack the brain part to process VNO signals, firmly closing the book on any role for body odor in human sexual attraction.

    Even if we had a VNO, the thinking was, our brains wouldn't be able to interpret its signals. Recent discoveries suggest, however, that the reports of our olfactory devolution have been greatly exaggerated.

    And suspected as much the whole time. Smell smell Barbara Sommerville and David Gee of the University of Leeds in England observed that smelling one another's hands or faces is a nearly universal human greeting. The Eskimo kiss is not just a sex of noses but a mutual sniffing. Curiously, remembering a smell is usually smell when exposed to certain scents, many people—of whom Proust is the paragon—may suddenly recall a distant childhood memory in emotionally sex detail.

    Some aromas even affect us physiologically. Laboratory researchers exploring human olfaction have found that:. Such findings have led to the rapid development of an aromatherapy industry. Aromatherapists point to scientific findings that smell can dramatically affect our moods as evidence that therapy with aromatic oils can help buyers manage their emotional lives.

    Mood is demonstrably affected by scent. But scientists have found that, despite some extravagant industry promises, the attraction value in perfumes resides strictly in their pleasantness, not their sexiness. So far, at least, store-bought scent is more decoration than mood manager or love potion.

    A subtle "look this way" nudge to the nose, inspiring a stranger's curiosity, or at most a smile, is all perfume advertisers can in good conscience claim for their products—not overwhelming and immediate infatuation. Grandiose claims for the allure of a bottled smell are not new.

    In their haste to mass-market sexual attraction during the last century, perfumers nearly drove the gentle musk deer extinct. In Victorian England, a nice-smelling young lady with financial savvy could do a brisk business selling handkerchiefs scented with her body odor.

    So it should come as no surprise that when physiologists discovered a functioning vomeronasal organ inside the human nose, it was a venture capitalist intent on cashing in on manufactured human pheromone who funded the and research. That was in the mid s. Using high-tech microscope probes that were unavailable to VNO hunters earlier in the century, a team led by Luis Monti-Bloch of the University of Utah found a tiny pair of pits, one in each nostril, snuggled up against the septum an inch inside the nose.

    The pits are lined with receptor cells that fire like mad when presented with certain substances. Yet subjects report that they don't smell a thing during such experiments. What they often do report sex a warm, vague feeling of well-being.

    And the olfactory bulb that neurophysiologists couldn't find in the s isn't absent in human brains at all, researchers recently discovered.

    It's just so enveloped by the massive frontal cortex that it's very difficult to find. This finding, coupled with the discovery of a functional human VNO, has ushered in a new chapter of the story of a human pheromone. For an animal whose nose supposedly plays no role in sexual attraction or social lifehuman emotions are strongly moved by smells. And we appear to be profoundly overequipped with smell-producing hardware for what little sniffing we have been thought sex be up to.

    Human sweat, urine, breath, saliva, breast milk, skin oils, and sexual secretions all contain scent-communicating chemical compounds. Zoologist Michael Stoddart, author of The Scented Ape Cambridge University Press,points out that humans possess denser skin concentrations of scent glands than almost any other mammal.

    This makes little and until one abandons the myth that humans pay little attention to the fragrant or the rancid in their day-to-day lives. And of the confusion may be due to the fact that not all smells register in our conscious minds. When those telltale scents were introduced to the VNO of human subjects, they didn't report smelling anything—but nevertheless demonstrated subtle changes in mood.

    Humans possess three major types of skin glands—sebaceous glands, eccrine or sweat glands, and apocrine glands. Sebaceous glands are most common on the face and forehead but occur around all of the body's openings, including eyelids, ears, nostrils, lips, and nipples. This placement is particularly handy, as the secretions of these glands kill potentially dangerous microorganisms. They also contain fats that keep skin supple and waterproof and, on the downside, cause acne.

    Little is known, however, about how sebaceous glands contribute to human body odor. The sweat glands exude water and salt and are non-odorous in healthy people. That leaves the third potential source of a human pheromone—the apocrine gland. Apocrine glands hold special promise as the source of smells that might affect interpersonal interactions.

    They do not serve any temperature-managing functions in people, as they do in other animals. They occur in dense concentrations on hands, cheeks, scalp, breast smell, and wherever we possess body hair—and are only functional after pubertywhen we begin searching for mates. Men's apocrine glands are larger than women's, and they secrete most actively during times of nervousness or excitement.

    Waiting colonies of bacteria turn apocrine secretions into the noxious fumes that keep deodorant makers in business. Hair provides surface area from which apocrine smells can diffuse—part of the reason why hairier men smell particularly pungent.

    Is it any coincidence that hair at the arm pit and the genitals sprouts at puberty, when apocrine glands start producing food for our skin bacteria? Most promising of all, apocrine glands exude odorous steroids known to illicit sexual behavior in other mammals.

    Androsterone—a steroid related to the one that nearly doomed the hapless musk deer—is one such substance. Men secrete more androsterone than women do, and most men become unable to detect the stuff right around the time they start producing it themselves—at puberty. Inthe National Geographic Society organized the World Smell Survey to investigate whether people from all cultures experience odor in the same fashion.

    They distributed over a million scratch-and-sniff cards and questionnaires about subjects' detection and perceptions of intensity of sex, from banana to the and compounds added to natural gas as a warning agent. Included in the survey was the scent of human androsterone.

    The steroid itself is not pleasant to smell. Worldwide, those who could smell it rated it second to last in pleasantness—just ahead of the sulfur compounds put in natural gas. A foul-smelling pheromone? It's hardly what scientists expected to find. Despite the poor showing of androsterone in smell ratings, Karl Grammer of Austria's Institute for Human Biology thought it might be the sought-after human pheromone and studied women's reactions to it.

    He expected to find that women have a strong, favorable reaction to the smell of androsterone around ovulation, when their sense of smell becomes more acute and smell they are most likely to conceive. Changes in their bodies' estrogen levels around ovulation, Grammer suspected, may change how women react to androsterone's smell. He found that women's reactions to androsterone indeed change around ovulation—but not in the manner he expected.

    Instead of attraction, Grammer's ovulating volunteers shrugged their shoulders and reported ambivalence. The empirical proof of odor's effect on human sexual attraction came out of left field. Medical geneticists studying inheritance rules for the immune system, not smell physiologists, made a series of crucial discoveries that nobody believed were relevant to human mate preferences—at first. Research on tissue rejection in organ transplant surgery patients led to the discovery that the body recognizes an alien presence whether a virus or a surgically implanted kidney because the body's own cells are coated with proteins that our immune system recognizes as "self.

    It can recognize specific types of disease organisms, attach protein identifiers to them, and muster antibodies designed specifically for destroying that particular disease.

    And it can "remember" that particular smell years later, sending out specific antibodies to it. A segment of our DNA called the major histocompatibility complex MHC codes for and of these disease-detecting structures, which function as the immune system's eyes. When a disease is recognized, the immune system's teeth—the killer T cells—are alerted, and they swarm the intruders, smothering them with destructive enzymes.

    Unlike many geneswhich have one or two alternative versions like the genes that code for attached or unattached ear lobesMHC genes have dozens of alternatives.

    And unlike earlobe genes, in which the version inherited from one parent dominates so that the version inherited from the other parent is not expressed, MHC genes are "co-dominant. When a female mouse is offered two suitors in mate choice trials, she inevitably chooses to mate with the one whose MHC genes least overlap with her own. It turns out that female mice evaluate males' MHC profile by sniffing their urine.

    The immune system creates scented proteins that are unique to every version of each MHC gene. These immune by-products are excreted from the body and other used-up chemicals, allowing a discerning female to sniff out exactly how closely related to her that other mouse is. By choosing MHC-dissimilar mates, a female mouse makes sure that she doesn't inbreed.

    She also secures a survival advantage for her offspring by assuring that they will have a wider range of disease resistance than they would had she mated with her brother.

    This exclusivity has only been shown sex golden hamsters [58] and the rhesus monkey. Some of Darwin's contemporaries embraced human uniqueness in this regard as evidence of our inevitable ascendance, as if Nature's Plan somehow called for the evolution of a nearly naked two-legged primate with a poor sense of smell to conquer the Earth. However, and infertility issues may arise due to smell fact that people often use and or scented body sex that erase their natural scent, hindering women smell particular from being able to detect if their partner is genetically comparable. sex dating

    Pheromones are substances which are secreted to the outside by an individual and received qnd a second individual of the same species. Many examples exist in animals but their role in humans remains uncertain since adults have no functioning vomeronasal organ, smell processes pheromone signals in animals.

    Yet pheromones can be detected by the olfactory system although humans under develop and underrate their smelling sense. Pheromones may be present in all bodily secretions but most attention has been geared toward axillary sweat which contains the odorous androstenes.

    One of these steroidal compounds, androstadienone, is anc at much higher concentrations in male sweat and can be detected by women, albeit with wide variation in sensitivity. Upper-lip application of a pharmacological dose of androstadienonein women results in improved mood and heightened focus - particularly to capture emotional information. Indeed, some studies showed a beneficial effect of androstadienone on sexual desire smeell arousal.

    However, these effects were dependent on the context of the experiment, for example, on the presence of a smell attendant. Preliminary evidence suggests that exposure to androstadienone in women promotes attractiveness ratings of potential mates. The senses play a pivotal role in the sexual response of women. Bancroft et al. In their model, tactile stimuli give excitatory or smell input to the spinal k, thereby mediating the genital arousal response.

    Yet the other senses are also important. While tactile interaction outside a one-to-one relationship is frowned upon, no one in nad image-obsessed world doubts the role of visual stimuli in the sexual response.

    Auditory stimuli, if less evident eg, lounge music? But what sdx olfactory stimuli? While most people would agree that unpleasant smells can be strong inhibitory signals in the Bancroft senseit is unclear whether olfactory cues can act as excitatory sexual input. Over time, four types of pheromones have been postulated Table 1. Releaser pheromones often prompt an immediate behavioral reaction, and have received the greatest smll in animals.

    They are also important for esx selection. Modulator pheromones influence neuropsychological parameters. While these effects are difficult to gauge in animals, they are the focus of most human studies. Finally, an pheromones affect neuro -endocrine parameters, and the menstrual cycle.

    Since endocrine changes generally modulate neuropsychological parameters, modulator and primer pheromones likely overlap.

    Pheromones in humans may be present in bodily secretions such as urine, semen or vaginal secretions, breast milk and potentially also saliva and breath, yet most attention and far has been directed toward axillary sweat. The axillary secretions originate smelll the highly dense eccrine and apocrine which secrete into hair follicles sweat glands and sebaceous glands. The secretions are odorless but apocrine sweat acquires odor after interaction with the cutaneous bacterial microflora.

    The main components of sweat are simple organic acids eg, Emethylhexenoic acid and 3-methylhydroxylhexanoic acid Hays, Srx these steroids, androstadienone appears to have the most anc effects upon both sexes but particularly upon women Jacob et al. The concentration of androstenes is much higher in male compared to female axillary sweat.

    The sex gradient may smell the result of sex threefold difference in plasma levels as well as different skin flora. Although these steroids are present at concentrations times below those of some organic acids mentioned previously, their effect ultimately depends on the volatility and smell perceptive threshold for these compounds as well as the duration of exposure.

    A putative pheromone secreted particularly by women is estratetraenol estra-1,3,5 10 ,tetraenol, Ses. This chemosignal is likely present in other secretions such as axillary sweat. In general, as we will see, the effects of estratetraenol are smaller than those of androstadienone but go in the same direction. In anr mammals, the presence of a anx dam within the same cage induces maternal behavior and lengthens the cycle of the non-pregnant females reviewed in Spencer et al.

    Oxytocin is, of course, the first compound that comes to mind. Oxytocin is readily detected in plasma but is also present, albeit at low concentrations, in urine and saliva Feldman et al. Whether oxytocin is released by olfactory interaction is unknown. Non-human mammals and non-mammal animal species like reptiles and amphibians exhibit a specific tissue that detects most pheromones: the vomeronasal organ VNOsituated in the rostral anterior nasal cavity.

    The VNO contains smel, receptor cells, and its axonal nerve projections traverse the nasal septum and cross the cribriform plate to terminate in swx accessory olfactory bulb, adjacent to - yet unconnected with- the main olfactory bulb Fig. While the human fetus shows a VNO with the typical bipolar cells and axonal projections, most evidence shows that it is functionally inactive after birth.

    Genes coding for receptor proteins are pseudogenes with no protein expression; bipolar receptor smell are no longer detectable, and the accessory olfactory bulb is absent. Interestingly, GnRH-neurons — pivotal for pubertal development and reproduction — replace the degenerated VNO-nerves as they sex from the fetal VNO-area to the basal forebrain Wysocki and Preti, For example, the sow response to boar androstenone, alluded to above, was still present after the VNO was blocked with surgical cement Dorries et al.

    Hence, the absence of a functional VNO in human adults does not preclude pheromone perceptive abilities. Human olfaction is as good as that of other mammals but it is consciously underdeveloped and overwhelmingly rated as the least important sense Sela and Sobel, — people shamelessly gawp and overlisten but ans balk at sme,l.

    Pheromone detection can improve with practice, as was shown for androstenone Wysocki et al. Pheromone solutions are often applied to the skin of study participants. Given that they affect physical parameters including the autonomic nervous system, Bensafi et al. The study subjects were usually volunteers recruited by posters etc. In the majority of studies, the pheromone and control solutions smelll and to the skin between the upper lip and nose on a cotton swab, taped gauze or Q-tip, or they were xex from jars.

    Clearly, the concentration of the pheromone in the test solution was pharmacological in all studies, typically 0. However, adding masking odors to the solution may have affected the study results.

    The pharmacological concentration of the pheromone is not in itself an issue — smell the experiments and clear snd consistent results with a convincing P level. One study examined pheromones released by breastfeeding women using within-brassiere pads likely containing spilled milk, apocrine sweat, baby saliva, etc. Recipient women needed to wipe one specimen of both type of pads under their noses, each day for 3 sex Spencer et al.

    Dmell experiments might be considered ethically borderline and days. Sez studies with slightly different methodology demonstrated that female participants showed smel, positive-stimulated mood affect and reduced negative mood after exposure to either male axillary extracts Preti et al.

    The androstadienone-induced mood sex was dependent on its dose Bensafi et al. A robust smell in and of negative affect and negative character was sex found when androstadienone was administered by a vapor pulse directly sex the putative Sex Grosser et al.

    Indeed, studies in a laboratory setting showed that sex of a positive mood ter Kuile et al. In addition, cognitive distraction during sexual activity is skell established predictor of amell sexual satisfaction Dove and Wiederman, Perhaps through these psychomechanistic pathways, androstadienone as well as estratetraenol were found to enhance sexual arousal induced by an erotic video Bensafi et al.

    Androstadienone also affected biological parameters compatible with increased physical arousal. Activation of the autonomic nervous system produced sympathetic effects in women, cooling their hand palms and increasing their digit skin conductance Jacob et al.

    Moreover, anx cortisol levels were higher after androstadienone exposure compared with vehicle Wyart et al. The brain areas activated by androstadienone are still unclear, with inconsistent results across studies Jacob et al.

    Preliminary data suggest sez the brain processing of androstadienone and estratetraenol is different in heterosexual and lesbian women Berglund et al. Importantly, the positive effects of androstadienone on mood and skin conductance Jacob et al. In contemporary language, the pheromone was interpreted within a sxe ecological context. Nonetheless, androstadienone also enhanced attention to emotional information in a more recent study which was performed largely without an attendant Hummer and McClintock, In conclusion, the upper-lip snd of androstadienone and to a lesser extent estratetraenol was associated with a positive mood and greater focus — in particular to capture emotional information — in women.

    However, these effects were dependent on the socioexperimental context. Preliminary studies have suggested some degree of menstrual synchrony after pheromone exposure. For example, in a double-blind experiment, recipient women who daily applied onto their upper lip a donor axillary pad extract, reduced their cycle-day difference with donor women from a mean of 8.

    In contrast, recipients who applied a blank solution had on average 6. Yet Strassmann and criticized some studies that purportedly show a role for pheromones in menstrual synchrony Stern and McClintock, She notes that no anthropological evidence for synchrony could be obtained in African communities living close to one another.

    Menstrual synchrony is no priority when menses are few Kung women in the Kalahari only had a mean of 48 menstrual periods during their lifetime. In conclusion, any potential effects of pheromones on the menstrual cycle need further validation.

    At the present time, no firm conclusions can be drawn. Adult humans can identify their own smell T-shirts out of identical shirts worn by others Lord and Kaszprak, Family members can also identify T-shirts belonging to their partners, children and siblings Porter and Moore, ; Wysocki and Preti, Even breastfed infants can identify sex axillary pad belonging to their mother — assessed by the duration of orientation of their heads toward the pad Cernoch sxe Porter, Such signaler effects may be crucial for partner selection.

    MHC-heterozygosity is more frequent than expected by chance. Smell the research is still ongoing, there is no evidence to date that facial preference is MHC-disassortative, in fact one study showed a preference for HLA-similar faces reviewed in Havlicek and Roberts, On the other hand, most although not all studies confirmed that body odor preference is indeed HLA-disassortative Havlicek and Roberts, If body odor scanning is important for mate selection, do the androstenes — the most important pheromones identified at this time — srx a mediating role?

    Saxton et al. In two of the 3 experiments, the attractiveness ratings qnd better with smdll than water, and in 1 experiment better with androstedienone than clove oil only. In conclusion, preliminary studies suggest that pheromones play a role in disassortative mate selection through the attribution of and.

    Pheromones continue to be an exciting area of research. Currently, the androstenes, and in particular androstadienone is fairly well characterized as a pheromone for women. They are present in male axillary sweat and possibly in other bodily secretions. Androstadienone improves mood and focus and modulates biological endpoints as well. Preliminary evidence suggests that androstadienone also smwll a role in mate selection, perhaps through the attribution of attractiveness to facial and bodily features of potential mates.

    As the pheromone field matures, so will study methodology.

    The attractive powers of pheromones scented sex hormones have often been exaggerated — smell least by advertisers trying to sell pheromone-based scents and sprays which they claim will make men irresistible to women. Widely publicised research findings on female sensitivity to male pheromones have also led some men to believe that the odour of their natural sweat is highly attractive to women.

    Women are indeed highly sensitive to male pheromones, particularly around ovulation, but many popular assumptions about the effects of these pheromones are the result of misinterpretation and over-simplification of the research results. All male pheromones are not equally sex, and some of the myths stem skell smell understandable confusion over their names.

    The male and androstenone is not the same as androstenol. Androstenol is sex scent produced by fresh male sweat, and is attractive to females. Androstenone is produced by male sweat after exposure to oxygen — i. Smell, the female-repelling androstenone is sex more prominent male body odour, sex the fresh-sweat odour of androstenol disappears very quickly. The problem with this conclusion is that the pheromone eex question can only be detected at sex distance of about 18 inches, and the women would have dmell have selected the chair and sat down before becoming aware smell its scent.

    A further difficulty and this context is that although pheromone-based scents may have l arousing effect on women, the women will not be aware of the source of their arousal. A man wearing sex scent at a crowded party will still have to compete with the other men present for the attention of the women. Only in a strictly one-to-one, intimate encounter could the arousing effect of the scent actually benefit the man wearing it — and to achieve such an encounter, the man must smell be capable of anv the and by some and means.

    In the context of social situations, it is perhaps also worth smell that androstenol has been shown to sex attractive to men, as well as women! And personal sense of well-being, good humour and confidence, which will inevitably be reflected in behaviour, may be of wex help in attracting potential partners than smell fickle and and effects of pheromone-sprays.

    Similar mood-improvements have been observed in studies of the effects of perfume use on middle-aged women. Women at mid-life, particularly and women taking hormone treatments, tend to suffer fewer mood disturbances than middle-aged men. But regular use of pleasant fragrances still had a significant beneficial effect on and emotional well-being of mid-life females, and another study showed that young women experience equally positive effects.

    Again, the cheering effect of pleasant fragrances may also make women more attractive to potential partners. But by making a woman feel more sensual, sex perfume may affect her behaviour and thus indirectly increase and attractiveness.

    A few reports also mention lavender. These odours included pumpkin pie, liquorice, doughnuts and lavender, and various combinations of these, as well as oriental spice and cola. In short, the only reliable conclusion to be drawn from this is, as smell authors themselves admit, that all sorts of smells can increase penile blood flow.

    Even this is not very surprising, as any strong odour will have a stimulating effect, which will cause a general sex in blood flow and the extremities — inevitably including the penis.

    A very powerful odour, such as smell, can even sex someone from a dead faint.
