A double-blind, placebo-controlled study of a

synthesized putative female pheromone was conducted with regularly menstruating, university women (N=36, mean

age=27.8). The pheromone formula was derived from earlier work investigating the underarm secretions of fertile,

sexually active, heterosexual women. A vial of either synthesized pheromone or placebo was selected blindly and

added to a subject's perfume. Subjects recorded seven sociosexual behaviors and reported them weekly across three

menstrual cycles. Beginning with Day 8 of each cycle, the first cycle contained a 2-week baseline period followed by

an experimental period of as many as 3 weeks each from the next two cycles for a maximum of 6 weeks. The 19

pheromone and 17 placebo subjects did not differ significantly in age, weight, body mass index, dating status or

ethnicity nor in reported accuracy, back-filling data, perception of a positive effect or perfume use. Placebo

subjects were significantly taller than pheromone subjects. Except for male approaches, subjects did not differ

significantly at baseline in average weekly sociosexual behaviors. A significantly greater proportion of pheromone

users compared with placebo users increased over baseline in frequency of sexual intercourse, sleeping next to a

partner, formal dates and petting/affection/kissing but not in frequency of male approaches, informal dates or

masturbation. Three or more sociosexual behaviors increased over baseline for 74% of pheromone users compared

with 23% of placebo users. We conclude that this synthesized pheromone formula acted as a sex attractant

pheromone and increased the sexual attractiveness of women to men.

Small sample group but the results

are very significant!
