Woman's scent can lure or repel

A woman's body odour can help her attract men when she is at her most fertile and repel them when she is not,
scientists have said.
According to a report in the journal Ethology, when a woman is at the most
fertile part of the menstrual cycle her armpit odour is at its mildest.
But when she is having a period, and
not ready for pregnancy, the smell changes to an acute, repellent odour.
The researchers studied 12 women who
wore armpit pads for 24 hours a day.
A number of primate species display changes during their fertile period,
but the majority of scientists believed that this was not the case with humans.
Subconscious cue
The 12 women were restricted from eating certain foods and from using deodorant or hormonal contraceptive.
They provided odour samples on the armpit pads, which were then presented to 42 men, who sniffed them and assessed
the attractiveness of the scent.
"Axillary odour from women in the follicular phase was rated as the most
attractive and least intense," the study's leader Dr Jan Havlicek, from Charles University in Prague, Czech
Republic, said.
"The results suggest that body odour can be used by men as a cue to the fertile period in
current or prospective sexual partners," he added.
A previous study by the same team suggested that women
subconsciously prefer the aroma of dominant men when they are at the most fertile stage of the menstrual cycle.
Then the researchers asked 48 men to assess how dominant they felt.
The men then wore cotton pads in their
armpits for 24 hours, which were subsequently presented to 65 women. Those who were ovulating rated the "dominant"
men as sexiest, but there was no similar pattern among women at other stages of their menstrual cycle.
Not a call for volunteers

Axillary odour is probably not the only odour cue to ovulation. Another
potential source of relevant olfactory information could be changes in vaginal odour. It is known that the peak of
pleasantness corresponds with the late follicular (ovulatory) phase (Doty et al. 1975; Keith et al. 1975). However,
the pattern of changes in individual women was highly
heterogeneous. The hedonic changes in perception of the
vaginal odour can be due to the changes in relative concentration of short aliphatic acids (Michael et al.
1975).
Note that it is unlikely that any of the men on the Forum will be called upon for a
correlative work.
