The next time you get caught cheating, just blame nature and your physiology. Women who have a high level of the sex hormone oestradoil may be more likely to cheat, according to a recent study of 52 women aged 17 to 30. Women with high levels of oestradoil are highly fertile and feel more attractive, which makes them more likely to flirt, kiss, or have a serious affair. Highly fertile women apparently tire easily of long-term partners and are motivated to find more desirable partners. This excuse, however, won’t work if you’re just having casual sex on the side because women with high levels of oestradoil are usually serial monogamists. But then again, I doubt your man will be able to tell whether you have a lot of oestradoil. Can they make a T-shirt for that? [Science Daily via AOL]
