We evaluated individual video-taped fifteen-minute interactions of fourteen women with fertile phase levels of Luteinizing Hormone (LH) during a cooperative task. During the task, our male accomplice wore either a standardized androstenol / androsterone mixture diluted in propylene glycol, or just the diluents; with sandalwood odor added to keep him blind to his condition.
When he was wearing the mixture compared to when he wore the diluent, women were more likely to make eye contact (t (12) = 3.43, p = 0.01; IRR: r = 0.964, p = 0.01). They also laughed more (t (12) = 5.20, p < 0.01; IRR: r = 0.810, p = 0.01), and they subsequently rated themselves as being more attracted to him (t (12) = 2.786, p = 0.016).
Our results combine the known effects of androstenol on LH and on mood with a likely behavioral affect of androsterone.
