The present work represents a pilot study in the area of olfactory communication in humans. On the basis of experiments, it is demonstrated that women are able to detect, by means of smell, a number of morphological and psychological characteristics of men. The samples of sweat from 29 young men were collected, as well as anthropometry measurements (interpupillary distance, height and width of the lower jaw, and so forth) and behavioral characteristics (personality questionnaire NEO, risk-taking questionnaire, Sandra Bem masculinity and femininity indices, a self-rating on aggression Buss-Perry questionnaire). Data on hormonal status of all males were collected (testosterone and cortisol). It is demonstrated that women are able to detect both morphological (masculinity, physical health) and psychological characteristics (aggression, risk taking, neuroticism, extraversion, cooperation, etc.). The smell of men rating high on cortisol is estimated as the least attractive. On the contrary, the sweat of men with combination of high level of testosterone and low level of cortisol is considered the most attractive. Females rating of male's smell differed depending on a phase of a monthly cycle. The data obtained are discussed in the light of evolutionary basis of permanent partner choice.
