Women “Smell” Their Competition

A recent study found that competition among women have a very high chance of being olfactory. The whiff of a woman close to ovulation is enough to stimulate another woman's testosterone levels and increase her desire to compete.
Though women are not aware of it, the scent of a woman close to ovulation triggers a testosterone boost in the smelling female. And testosterone has been proven to affect behavior.
"It's well known that testosterone is linked to aggression and competitiveness," lead author Jon Maner, a Florida State University psychologist explained. "Based on our testosterone findings, one could speculate that women exposed to the scent of ovulation might become more antagonistic or competitive."
The study that has been published in the journal Evolution and Human Behavior by Maner and co-author James McNulty, measured the testosterone levels of women before and after they sniffed t-shirts that were previously worn by other women aged 18 – 21. The women whose shirts were taken in for the research were instructed to wear the shirts when they were at high fertility (days 13, 14, and 15 of the menstrual cycle) and at low fertility (days 20, 21 and 22).
During the study, the t-shirt wearers refrained from engaging in sexual activity, they showered with unscented soap and shampoo, did not use any perfumes or deodorants, did not smoke, and avoided eating pungent foods such as garlic, onions and asparagus.
The sniffers were told that the study was researching on “how much we can tell about another person without even meeting them”. They were not told of how and when the t-shirts were collected.
The women exposed to the scent of high fertility females displayed greater levels of testosterone, and the women who smelled the t-shirts of low fertility females actually had a significant decrease to their testosterone levels.
So boys if you are thinking of introducing your girlfriend to one of your female friends, be sure to schedule it on their "low-peak" days to ensure a catfight does not break out.
