American scientists have revealed that when women are at their most fertile they find the scent of other women attractive.
The study had two sets of scent donors as participants, 21 naturally-cycling women and 12 women taking the pill.
The study studied data of 96 women between the ages of 18 and 40.
These women were asked to rate scents in two ways, the first one involved choosing between two scents from the same woman – when at her most fertile and at her least fertile.
They were also asked to rate individual scents in terms of pleasantness, sexiness and intensity, between one and nine.
The researchers from the Chapman University in California said like men, women rated naturally-cycling women’s high-fertility scent samples than their low-fertility samples.
The authors said: “The findings indicate that, like men, women perceive cues of high fertility in other women as attractive. Specifically, women rated other women’s high-fertility natural body scents as more pleasant, sexier, and perhaps less intense than their low-fertility scents.”'
According to Daily Mail, the possible explanations for this could be that the ability to detect differences in another female’s fertility is an indication of an ability that evolved in an animal ancestor.
It could also be that the feature works in women as ‘a mere by-product of their shared physiology with men.'
The authors of the study believe that these must have given women an advantage in the past for it to have continued in women today.
Forty-eight of the ‘testers’ were heterosexual, 22 were gay and 16 bisexual.
