Women Hormones - The Effects of Oestradiol

When a woman has the presence of a specific hormone in her, she will appear more attractive than other women who don't have it. According to studies, however, these same hormones can also create a desire for women to cheat on their partner.

A University of Texas phychologist named Kritina Durante and her fellow psychologist Norman Li found that women with a larger amount of the hormone oestradiol present in them will have a greater desire to flirt, exchange kisses, and even possibly be involved in an affair.

Biology Letters

A British journal entitled the Biology Letters published a study in which the same psychologists said that this type of behavior was not the same as a one-night stand, but rather a kind of opportunist and serial monogamy. Certain hormones in women, according to Durante and Li, can result in women wanting to look for a relationship that is better than the one they have currently.

When searching for that relationship, these women are willing to leave the person they are with to be in one that will be more beneficial for them.

Physical Characteristics

Other studies about the hormone oestradiol show that women with higher levels of it are more fertile, have larger breasts, have more attractive facial features, and a lower waist to hip ratio. All of these characteristics enhance the appearance of women, which will bring them more attention from men.

Both Durante and Li went further and calculated the oestradiol levels at various points in the menstrual cycle of women, specifically women who were not on birth control between the ages of 17-30, as well as those over the age of fifty. Women with greater levels of oestradiol also were considered more attractive and more willing to participate in an affair outside their marriage.

Therefore, one can draw a conclusion that whether a woman decides to cheat on her partner or not is influenced quite a bit by her hormone level. Since women with higher levels of oestradiol are considered more attractive, this means that they will probably be presented with more opportunities to explore new relationships with different men.
