“…Skatole (3-methylindole, M 131.17 g/mol; AldrichChemie, Steinheim, Germany) and androstenone (16, (5α)-androsten-3-one, M 272.43 g/mol, Steraloids Inc., Newport, US) were dissolved in propylene glycol (1,2-propanediol, M 76.10 g/mol; Carl Roth, Karlsruhe) to achieve concentrations of 2 μg/ml and 20 μg/ml for skatole and androstenone, respectively. The absolute amount of androstenone was with slight modification chosen according to Pause, Rogalski, Sojka, and Ferstl (1999) and Lübke, Schablitzky, and Pause (2009). Propylene glycol is a relatively odourless, non-toxic solvent.…”

“…Chemosensory aggression signals, present within axillary sweat, were chosen because such signals are considered to act as inherently “honest signals” (for discussion, see Lübke et al, 2017 ); hence, their effects should be valid universally (i.e., they are unaffected by cultural or social learning factors). Moreover, sexual orientation has already been shown to affect responses to non-emotional axillary sweat (Lübke et al, 2012 ; Martins et al, 2005 ), as well as to sweat compounds probably involved in the communication of aggression (Lübke & Pause, 2014 ; Lübke et al, 2009 ). It has repeatedly been shown that chemosensory signals are processed as highly relevant, and exert significant behavioral effects without being consciously perceived as odors (de Groot et al, 2015 ; Pause et al, 2010 , 2020 ).…”

The current series of studies are the first to examine brain responses to social aggression signals as a function of male and female sexual orientation. For the first set of studies (1a, 1b), axillary sweat had been collected from 17 heterosexual men and 17 heterosexual women aggressively responding to frustrating opponents (aggression condition) and while playing a construction game (control condition). Sweat samples were pooled according to sex and condition, and presented via a constant flow olfactometer to 17 gay and 23 heterosexual men (Study 1a), and 19 lesbian and 25 heterosexual women (Study 1b). Ongoing EEG was recorded from 61 scalp locations, chemosensory event-related potentials (CSERPs; P2, P3-1, P3-2) were analyzed, and neuronal sources calculated (low resolution electromagnetic tomography). Within the second set of studies (2a, 2b), pictures of males’ and females’ weak angry and neutral facial expressions were presented to 21 gay and 23 heterosexual men (Study 2a), and 19 lesbian and 26 heterosexual women (Study 2b), and ERPs (N170, P3) were analyzed. Gay men showed larger P3-1 amplitudes than heterosexual men upon presentation of male aggression sweat, accompanied by activation of the right inferior frontal gyrus (IFG, BA 10). Gay men also displayed longer N170 latencies in response to men’s compared to women’s angry facial expressions, while heterosexual men did not. In women, sexual orientation did not affect the processing of aggression sweat or anger expressions. Gay men showed preferential processing of chemosensory aggression signals (P3-1 amplitudes), indicating fine-tuned socioemotional sensitivity, related to activation of brain areas involved in emotion regulation (IFG). They further process the relative relevance of visual aggression signals (N170 latency). These results were in line with theories proposing a common evolutionary pathway for same-sex attraction and traits easing social integration.

Pleasantness of the Odor of Androstenone as a Function of Sexual Intercourse Experience in Women and Men

et al. 2011

Androstenone (5α-androst-16-en-3-one) and other androstenes, body odor components occurring in apocrine secretions, may play a role in human chemosignaling. We hypothesized that the odor of androstenone may gain hedonic value from sexual intercourse experiences via associative learning. Young adults (N = 397, 61.5% women, age 21-24 years, randomly sampled regarding sexual experience) rated the intensity and pleasantness of the odors of androstenone, cinnamon, chocolate, isovaleric acid, lemon, and turpentine. Among women who were able to perceive androstenone, the odor was rated as more pleasant (less unpleasant) by those who had had experienced sexual intercourse with at least one partner (n = 175) than by those who reported never having experienced intercourse (n = 12, p = .006). The difference was specific to women. The results suggest that, among women, sexual experience may modify the pleasantness of the odor of androstenone.
