Pheromones may be present in all bodily secretions but most attention has been geared toward axillary sweat which contains the odorous androstenes. One of these steroidal compounds, androstadienone, is present at much higher concentrations in male sweat and can be detected by women, albeit with wide variation in sensitivity.
