Abstract
This study tested whether synthesized human
male pheromones increase the sociosexual behavior of men.
Previous data showed such was the case in women. 38 heterosexual
men, aged 26-42, completed a 2-week baseline period and 6-week
placebo controlled, double-blind trial testing a pheromone
"designed to improve the romance in their lives".
Each man kept daily behavioral records for 6 sociosexual behaviors
FAXing them weekly:
- Sexual intercourse
- Sleeping next to a romantic partner
- Petting/affection/kissing
- Informal dates
- Formal dates
- Self stimulation to ejaculation (masturbation)
Significantly more pheromone than placebo users
increased above baseline in
- Sexual intercourse and
- Sleeping next to a romantic partner.
There was a tendency for more pheromone users
than placebo users to increase above baseline in
- Petting/affection/kissing, and
- Informal dates.
No significant difference resulted from pheromone
use vs. placebo use for
- Self stimulation to ejaculation or
- Formal dates.
A larger proportion of pheromone than placebo
users increased in
- >=2 of the 5 sociosexual behaviors involving
a female partner (58% vs. 19%); and
- >=3 of the 5 sociosexual behaviors
involving a female partner (41% vs. 9.5%).
Thus, human male pheromones topically applied
in aftershave lotion caused a significant increase in male
sociosexual behaviors in which a woman's sexual interest plays
a role, but not in male masturbation which clearly reflects
male sexual interest. We suggest that human male pheromones
increased the sexual attractiveness of men to women.
Results
During the 6 experimental weeks, daily calendars
showed an average use of the aftershave of 5.82 (±
.98) days per week for pheromone users and 5.29 (±
1.24) days per week for placebo users. Usage did not differ
significantly between the 2 groups (t<1).
The proportion of subjects in the pheromone
and placebo groups who increased over baseline are detailed
in Table II.
A significantly higher proportion of pheromone
users than placebo users showed an increase over baseline
for Sexual intercourse and Sleeping next to a romantic partner.
There was a tendency for a greater number of
pheromone users to increase above baseline in Petting/affection/kissing
and Informal dates.
The proportions of pheromone and placebo users
showing an increase over baseline in Self-stimulation to ejaculation
and Formal dates did not differ significantly.
A larger proportion of pheromone than placebo
users increased over baseline in >=2 (p=.01) and >=
3 (p=.02) of the five sociosexual behaviors involving a female
partner.
A significantly higher proportion of
pheromone (47%) than placebo users (24%) perceived positive
results during the 6-week experimental period (Z=5.05, p <.001).
