Thirty-seven female hamsters, treated with either sesame oil or testosterone postnatally on days 2, 4, or 10 of life, and 25 male hamsters were given either olfactory bulbectomies or sham operations and tested for mounting behavior in adulthood. Extensive lesioning of the olfactory bulbs eliminated mounting in all subjects, suggesting that the mounting of early androgenized females is dependent upon the same sensory channels as the mounting of the males.
