While many people perceive a foul odor from androstenone, usually that of stale urine or strong sweat, others find the scent sweet and pleasant. New research from Rockefeller University, performed in collaboration with scientists at Duke University in North Carolina, reveals for the first time that this extreme variability in people's perception of androstenone is due in large part to genetic variations in a single odorant receptor called OR7D4.Androstenone, found in higher concentrations in the urine and sweat of men than of women, is used by some mammals to convey social and sexual information, and the ability to perceive androstenone's scent may have far-reaching behavioral implications for humans.To many, urine smells like urine and vanilla smells like vanilla.But androstenone, a derivative of testosterone that is a potent ingredient in male body odor, can smell like either - depending on your genes.
New research traces this variability to mutations in a single odorant receptor gene, a finding that raises questions of how people detect other people's body odor.
This is sad, but so detailed that one has to respect the subtle, albeit dark little nugget of humor.
