| Health EQ: Androstadienone, Sweat, Smell and Sex Popular Health Issues-Facts and Prevention |
Claire Wyart from the University of California at
Berkeley reported that people secrete a scent that
influences the hormones of the opposite sex.
Androstadienone found in male sweat, saliva and
semen affected women's mood, sexual and
physiological arousal and brain activation. [2]
Delta 4,16-androstadien-3-one (androstadienone)
alters cerebral glucose utilization both in subcortical
regions and in areas of the neocortex not exclusively
associated with olfaction. [3]
Researchers found that smell of androstadienone shot
up cortisol levels within 15 minutes and stayed
elevated for up to an hour in the study of 48 female
undergraduates at Berkeley. In general, cortisol helps
maintain proper arousal and sense of well-being,
respond to stress and other functions. [2]
In fact, researchers have found that for both men and
women odors influence mood, which in turn influences
pain unpleasantness perception. Some studies
showed that the steroid androstadienone modulates
mood differently in men and women, improving mood
in women and worsening it or leaving it unchanged in
men. In the absence of pain, androstadienone
improved mood only in women, while the pleasant
odorants improved mood for both sex. [1]
Interestingly, Villemure C and Bushnell MC from McGill
Centre for Research on Pain found the presence of
androstadienone increased perceived pain intensity
especially in women, suggesting an effect of
androstadienone on pain perception, independent of
mood changes. [1]
