    Smell is a widely used social information exchange channel in the animal world, with individuals secreting chemical signals (information, also known as feromon) as carriers, specific neuropeptides and hormones play an important role in the processing of chemical signals.
    that human odors can transmit social information among individuals, and their effects usually occur at the conscious level.
    Two of these human steroid substances have been found to effectively transmit gender information in a manner specific to the recipient's gender and sexual orientation, and to activate the lower pasum (an important brain region responsible for reproduction).
    Specifically, male disterone (androsta-4, 16, -dien-3-one), which is found mainly in men's semen, underarm skin and hair, transmits male messages to heterosexual women and gay men and activates their lower celelams; Female tetraene (estra- 1,3,5 (10), 16-tetraen-3-ol) found in women's urine transmits female messages to heterosexual men and activates the heterosexual and gay women's subsolams.
    among the hormones produced by the hyalural brain, oxytocin and vasopressin, two structurally similar nine peptides, are closely related to reproduction and social behavior during evolution, their receptors are also expressed in the olfactory system, and expression patterns are regulated by sex hormones.
    oxytocin-pressurized system mediate human decoding of chemical sex cues? Using psychophysical methods, Zhou Wei, a researcher at the National Key Laboratory of Brain and Cognitive Sciences at the Institute of Psychology of the Chinese Academy of Sciences, systematically assessed the relationship between oxytocin and pressurized hormones and the decoding of gender information carried by male and female tyrenne in a total of 1,056 tests of 216 male subjects.
    Through five step-by-step experiments, the researchers examined the modulation effects of steroids and estrogen on the sex perception of gay and straight men, how they were affected by nasal oxytocin, pressurizers, and their common antagonist, atosiban.
    experimental visual material is a light-point scity made by Nikolaus F. Troje, a professor at the University of York in the United Kingdom, who has made different degrees of digital deformation between men and women.
    Taking into account the relationship between individual social skills and endogenetic oxytocin levels and the heterogeneity of the effects of nasal oxytocin on individuals with different social abilities, the study further compared the differences between the decoding of chemical sex clues by individuals with high and low social skills between different drug intervention conditions. the
    study found that oxytocin, rather than pressurized, modulates the decoding of female information carried by heterosexual men to female terpenes and the decoding of male information carried by gay men to male steroids, a common antagonist Atosiban that blocks individuals' decoding of chemical sex cues.
    the modulation effect of oxytocin was dose-related, showing a dose-reaction pattern of inverted U-type and related to the recipient's own social abilities.
    individuals with low social skills (generally with lower endotopic oxytocin levels) do not make effective use of chemical sex cues, and oxytocin with nasal spray 12 IU restores that ability, while oxytocin at higher doses (24 IU) shows no benefit.
    individuals with high social skills (generally with relatively high levels of endotopotic oxytocin) can effectively decode and utilize chemical sex cues, which are impaired after 12 IU oxytocin nasal spray and eliminated after 24 IU oxytocin nasal spray.
    in both groups of individuals, the pressure-injected nose given 12 IU or 24 IU did not alter the condition of the chemical sex cue, i.e. the same as without drug use.
    that although humans are not as strongly driven by Fallomon as insects or mice, chemical signals undoubtedly affect our social perception and behavior.
    study shows that human processing of chemical signals is inextricable to the neuroendocrine process.
    the findings were published in eLife.
