摘要: A sex-related difference in olfactory sensitivity to androstenone has been reported occur during adolescence. More males than females exhibited anosmia androstenone, or an increase threshold with age. The current study addressed the question whether similar, sexually dimorphic effects of aging over puberty can also be found for androstadienone. total 102 subjects participated (36 females, 66 males). Similar previous investigations, were divided into a group 47 individuals mean age 13.3 years, defined as pre/peri-pubertal, and 55 17.1 post-pubertal. All underwent tests verbal abilities, general function, measurements androstadienone thresholds. provided following major results: (1) Male higher pre/peri-pubertal compared post-pubertal group. This was not observed female subjects. Correspondingly, negative correlation between male subjects, but (2) In contrast this sex-specific change odor threshold, skills identification abilities increased all regardless their sex. conclusion, present observations confirm research on sex-differentiated towards odorous steroids. While underlying causes are unknown, it may hypothesized that decreased could result from endogenous levels Future studies should include both steroid non-steroid odorants futher explore these age-related changes.
