Each

morning for a month female subjects placed either 5 alpha-androst-16-en-3 alpha-ol, a putative human pheromone, or a

placebo on the upper lip. Each evening the subjects rated on five scales their moods during that day. In the middle

of their monthly cycle those females exposed to androstenol rather than a control tended to rate their moods as

submissive rather than aggressive. The compound did not significantly influence ratings of being happy/depressed;

lethargic/lively; sexy/unsexy; irritable/good-tempered. The results are discussed in terms of the possible increased

olfactory sensitivity of the human female to androstenol in the middle of her monthly cycle

A natural

secretion, 5 alpha-androst-16-en-3 alpha-ol (androstenol) is speculated to function as a spacing pheromone. The

effect of the odor of androstenol on restroom-stall choices was investigated over a 5-week period. The first, third,

and fifth weeks served as baselines against which the effect of androstenol or a control odor, 3 alpha-hydroxy-5

alpha-androstan-17-one (androsterone) could be evaluated. During the second and fourth weeks, half of the stalls in

each restroom were treated with androstenol or androsterone, respectively. As predicted, men avoided the treated

stalls during the androstenol week only, and neither odor affected female stall selection, demonstrating a sex

differential influence of the experimental odor.
