High Hormone Levels in Women May Lead To Cheating
A new study has shown that high levels of the sex hormone oestradiol may lead to a woman having an affair.
Doctoral candidate Kristina Durante and Assistant Professor of Psychology Norm Li from The University of Texas at Austin studied the link between oestradiol, a hormone associated with fertility, and sexual motivation.
“The study offers further evidence that physiological mechanisms continue to play a major role in guiding women's sexual motivations and behavior,” Durante said.
Researchers looked at 52 females ranging in age from 17 to 30 and not using contraception. The women’s hormone levels were measured at two specific points during their ovulatory cycle and they were asked to rate their own physical attractiveness. They also answered survey questions on how likely they were to cheat on a partner.
The researchers found that a woman’s oestradiol level was associated with how physically attractive they saw themselves. Higher oestradiol levels showed that a woman was more likely to engage in flirting, kissing, and having an affair with someone new.
“Our findings show that highly fertile women are not easily satisfied by their long-term partners and are motivated to seek out more desirable partners,” Durante explained. “However, that doesn't mean they're more likely to engage in casual sex. Instead, they adopt a strategy of serial monogamy.”
This study was published in the Proceedings of the Royal Society of London: Biology Letters.
