Yet, whether such scents induce psychoneuroendocrinological Lady looking sex Bonsall in perceivers is still controversial. We studied if smelling axillary and vulvar odors collected in the periovulatory and late luteal phases of young women modify salivary testosterone and cortisol levels, as well as sexual desire in men. Forty-five women and men, all of them college students and unacquainted with each other, participated in the study. Female odors were collected on p affixed to the axilla and on panty protectors both worn the entire night before experiments.

Men provided five saliva samples, a basal one before the smelling procedure, and four more 15, 30, 60, and 75 min after exposure to odors. Immediately after smelling the odor source, men answered a questionnaire rating hedonic qualities of scents, and after providing the last saliva sample they answered questionnaire on sexual desire. We found that periovulatory axillary and vulvar odors increased testosterone and cortisol levels, with vulvar scents producing a more prolonged effect. Luteal axilla odors decreased testosterone and cortisol levels, while luteal vulva odors increased cortisol.

Periovulatory axilla and vulva scents ed for a general increase of interest in sex. These odors were also rated as more pleasant and familiar, while luteal vulvar odors were perceived as intense and unpleasant. Torso and axillary odors of women in the follicular phase are rated as ificantly more attractive than those of women in the luteal phase 2 — 5. Therefore, although human steroid metabolites for pheromonal-like effects 9provide relevant cues for mate choice 910 and al ovulation see abovewhether Lady looking sex Bonsall scents increase male sexual arousal by way of neuroendocrine pathways is debatable.

Testosterone increases [following a luteinizing hormone LH surge] in male stump-tailed macaques exposed to the vaginal odors produced around the time of ovulation Concerning human genitals, Michael et al. Yet, studies concerning the role of female genital scents have been largely confined to vaginal secretions [review in Ref. For example, men and women perceive vaginal ovulatory secretions as less unpleasant and much less intense than secretions produced on the other days of the menstrual cycle Vaginal secretions contain around odoriferous compounds, of which 34 are related to hedonic sensations while smelling it However, the presence of specialized exocrine glands in the vulvar area, along with the fact that human chemical communication might involve mixtures rather than isolated compounds 22suggests that the secretions of these glands, together with vaginal secretions and the normal metabolism of bacterial flora, would contribute to the formation of semiochemicals.

Considering that full bipedalism appeared around two million years ago, with Homo ergaster 26historically followed by clothing, and at sometime intimacy to copulate, a question of interest is why the human female genitals should retain semiochemical functions adequate to quadruped mammals. Taking this inintimate situations at least in historic and modern populations are needed so that men comfortably smell the female genitals.

Cunnilingus is a suitable sexual practice to gather semiochemical information of scents and flavors found in the female genitalia interestingly, for the armpit there is a similar practice: maschalagnia Yet, to our knowledge, no attention has been given to the likelihood that olfactory stimulation occurring during cunnilingus is also rewarding to the male, e. For example, pre-copulatory cunnilingus increases the duration of copulation in Indian flying foxes, Pteropus giganteus For that, we compared vulva and axilla scents collected in the periovulatory phase with scents collected in the luteal phase.

Increases in testosterone levels following mild intra-sexual competition in men also promote affiliative behaviors with women Yet, sexually arousing stimuli affect other hormones, including a decrease of cortisol 35 On the other hand, cortisol increases in squirrel monkeys when males are housed with new females 37and also in young men when socially interacting with unknown women 38 It is known that cortisol increases in humans in response to events threatening to self-esteem 40a situation likely to arise upon meeting a potential new sex partner.

In addition, we expected that participants would rate such odors as highly hedonic. On the other hand, we expected a decrease in testosterone levels and current interest in sex after smelling luteal odors, besides from rating these as disgusting, all these aling sexual disinterest.

However, we did not expect changes in cortisol levels, since sexual disinterest seems Lady looking sex Bonsall to elicit anticipatory cognitive appraisal. Female researchers interviewed women volunteers and male researchers interviewed men volunteers.

Women were asked to fill a brief questionnaire answering if they knew how long was their menstrual cycle; if they had had any irregular cycles in the past 6 months; if they kept track of the cycle; if they took hormonal contraceptives; if they were currently in a long-term relationship dating or living with a partner for more than 6 months ; what was their sexual orientation; if they have or had suffered any sort of genital infection e.

The 45 women chosen to participate in the study were all heterosexual, had regular cycles of 28—30 days, kept calendar track of the cycle, were healthy and had not suffered any gynecological illness, were not taking hormonal contraceptives and did not smoke. Once accepted as a participant, each woman was told to wait until the beginning of her next menstrual cycle and to present to the laboratory 1 or 2 days before reaching midcycle, and 2 or 3 days before she thought would start menstruating.

Male participants also filled a questionnaire answering what was their sexual orientation; if they were Lady looking sex Bonsall a long-term relationship same as women ; if they took anabolic steroids; if they were heavy drinkers or recreational drug users; if they smoked. The men we recruited were all heterosexual, non-smokers, not heavy drinkers, not drug users, and not taking anabolic steroids.

Once accepted, they were asked to provide their cell phonehouse telephoneand e-mail address in order to let them know in advance when they had to present to the laboratory. Since the NOMSSA requires disclosing to the volunteers the kind of research they are going to participate in, during recruitment interviews we told female volunteers their odors were going to be smelled and qualified by unknown men, while men were told they were going to breathe harmless body odors without giving information of the scent source or genderprovide saliva samples and answer two short questionnaires.

If they had no objections to collaborate, the participants ed a consent of agreement. Volunteers were paid around 15 USD for their collaboration; women were paid twice, once for each time they provided odor samples, while men were paid once for participating in the experiment. Payments were done the day they showed up to provide the samples or to the smelling test. When women presented to the laboratory 1 or 2 days before midcycle or before menstruation, they were given a clean, sterile cotton pad and a winged cotton panty protector wrapped separately in plastic bags, as well as one small roll of medical micropore tape.

They were instructed to wear the cotton pad in the armpit overnight affixed with micropore tape and the panty protector taking care it covered all the vulvar zone for at least 8 h during the middle day of their menstrual cycle, and during the night 24 h before menstruation. In this way we tried to minimize the bacterial flora breakdown of fresh odorless secretions into foul odorous compounds Women were also required to abstain from sexual intercourse for 24 h before wearing and returning the garments, from taking afternoon or night showers, and from eating spicy or heavily spiced food on those days.

Upon awakening, they had to repack the cotton pad and the panty protector separately in the plastic bags and return them first thing in the morning around — h to the female researchers. While in the lab, the women provided two 6 ml samples of saliva for further estradiol and progesterone evaluation; they were weighted and had their hips and waists circumferences measured. Estradiol and progesterone were used to confirm their menstrual cycle phase.

Our expected balance de of 45 odor samples for menstrual phase per odor source became unbalanced because 13 women in the periovulatory phase did not provide the vulvar sample; 8 from the above women and 3 more did not return to provide the luteal samples, and another 8 women provided the luteal axilla but not the vulvar sample.

On the day a woman attended the lab to gather the cotton pad and panty protector, three men were contacted and asked to present to the lab at 1 or 2 days later at h depending on the time the female student presented herself. They were also asked not to have sexual relations for 24 h before presenting to the lab. To minimize cueing the participants about the purpose of the study, we used a double-blind experimental de where participants did not know what they were smelling, while male experimenters who attended male volunteers were unaware of the odor condition being Lady looking sex Bonsall.

Every two men smelled odors from a single female: one from the axilla cotton pad and the other from the vulva panty protectorwhile a third one smelled air. The smelling experiments were done the same morning — h on which the odor samples arrived, when cortisol and testosterone levels are high 42 Female researchers placed each odor source inside the medicine compartment of a piston compressor nebulizer Modelvolume: 10 cm 3minimal air flow: 0.

Each man was taken to a different room and sat in front of a desk on which were placed Lady looking sex Bonsall assay tubes the nebulizer, a DVD player, and a TV set, an envelope enclosing the questionnaires and a packet of sugarless chewing gum. The use of chewing gum to stimulate saliva production was done ad libitum. The volunteer was asked to provide a first basal 6 ml saliva sample; he was then given a written set of instructions and a verbal explanation about the rest of the procedure. Immediately after, they had to answer a questionnaire about the perception of odors. Thereafter, to mitigate boredom, men were asked to watch a BBC video about whales or ocean life, providing further saliva samples 15, 30, 60, and 75 min after finishing the inhalation procedure.

A buzzer connected to a timer notified participants it was time to provide the sample. Given the unbalance introduced by the missing odors samples, 25 men smelled air, 45 periovulatory axilla odors, 32 periovulatory vulva odors, 34 luteal axilla odors, and 26 luteal vulva odors. For analyses we averaged each participant scores. The hedonic properties of odors questionnaire had four questions: 1 did you smell something yes, no ; 2 how familiar are you with Lady looking sex Bonsall odor; 3 how intense is this odor; 4 how pleasant is this odor. We collected a total of saliva samples.

To free the samples from mucopolysaccharides and proteins they were subjected to three subsequent freeze-thaw cycles. Inter-assay and intra-assay coefficients for testosterone were 8. Cortisol inter-assay coefficient was 8. The lower limit of sensitivity for testosterone was 0. We did not test for cross-reactions. The manufacturer report on testosterone cross-reactions with another androgens are: androstenedione, 0.

Cross-reactions with another glucocorticoids are: corticosterone, 8. Mean basal cortisol levels did not vary with relationship status. Testosterone values were normally distributed within odor sources and time of collection of saliva samples, while ratings of familiarity and intensity were normally distributed within odor sources. Cortisol, scores of the interest in sex, and ratings of pleasantness were not normally distributed.

Therefore, we did analyses on log-transformed cortisol values, and square root transformed scores of interest in sex and ratings of pleasantness. Our hormone sampling was not suitable for traditional repeated measures ANOVA, as odor sources for some women were missing and in the case of complete within-women samples, two distinct men breathed odors from a same female participant ing for autocorrelation.

Therefore, we used linear mixed models 48 to analyze the hormonal data, with time and odor source air, periovulatory axilla, periovulatory vulva, luteal axilla, luteal vulvaas fixed effects, and female or air testmale participants identities, and relationship status as random effects.

Linear mixed models were also used to analyze the interest in sex questionnaire and the hedonic properties of scents, odor source being the only fixed effect, and female or air testmale participants identities, and relationship status the random effects. Following the recommendations of Dickinson et al. Testosterone did not vary in men smelling air. Figure 1.

Smelling air had no effect on cortisol. Figure 2 shows back-transformed interest in sex scores with respect to odor source. On the other hand, odors from the luteal phase had no effect on interest in sex. Figure 2. Seventy-eight participants reported having perceived an odor, 15 of them Lady looking sex Bonsall smelled air.

Table 1 shows the mean ratings for familiarity, intensity, and pleasantness with respect to odor source. Yet, it should be noted that most of our male participants hinted being aware what they were going to smell see Participants. Roney and Simmons 7 used odors sampled for a very brief period following a brisk walk until female donors started sweating for 5 min before they returned the cotton pad affixed to the armpit to the researchers.

From their description of the procedure it is difficult to calculate how much time in average each of their female volunteers worn the cotton pad, but seemingly it was no much more than an hour. In common with all studies investigating airborne compounds, chemical communication studies done in humans are still plagued with dose-effect issues.

The endocrine confirm that female odors al reproductive status, inducing appropriate male physiological responses to deal with a potential mate and intra-sexual competition 32 Testosterone increased after smelling periovulatory odors, but the periovulatory vulva facilitated a more prolonged effect than the periovulatory axilla.

The shared effect of axillary and vaginal odors might arise from the fact that apocrine glands involved in the synthesis of putative steroidal pheromone-like compounds, such as androstanedione and estratetraenol 5253 are found mainly in the axilla 54but also in the labia majora 17 and the perineum The extended increase of testosterone elicited by periovulatory vulva odors suggests that genital compounds are more diverse and potent than those from the axilla, perhaps owing to the presence of more specialized glands in that area.

Luteal odors decreased testosterone. As mentioned, this result was first reported by Miller and Maner 6and might elicit a low testosterone status that decreases sexual desire 55or at least make women in the non-fertile days sexually uninteresting.

Cortisol also changed, according to our predictions, when periovulatory odors were involved: both axilla and vulva odors ificantly increased this glucocorticoid salivary level in the short term 15—30 minin a similar way to when men meet strange women 38 However, after half an hour, the effects of axilla and vulva odors were somewhat different.

Periovulatory vulva odors elicited a complex cortisol response, peaking at 15 min followed by a steady decrease, which reached a nadir at 75 min.
