WASHINGTON (Reuters) – Women with high levels of estrogen not only look and feel prettier -- but they may act on those feelings by moving from man to man, U.S. researchers reported on Tuesday.
Estrogen, the so-called female hormone, affects fertility and has been shown to make women dress more provocatively and show more thrill-seeking behavior.
Dr. Kristina Durante of The University of Texas at Austin and colleagues found that young women felt more attractive when they had high levels of an estrogen known as estradiol, and they acted on those feelings.
"Women with higher estradiol reported a greater likelihood of flirting, kissing and having a serious affair with someone other than their primary partner and were marginally more likely to date another man," Durante's team wrote in the Royal Society Journal Biology Letters.
"Results provide support for the relationship between physical beauty and fertility and suggest that women high in reproductive health engage in opportunistic serial monogamy -- being open to affairs and moving on to a new relationship if a higher-quality mate becomes available."
Durante's team tested 52 female undergraduates aged 17 to 30 who were not taking hormone contraceptives. They took two estradiol samples from each, as hormone levels fluctuate from week to week.
They had the women rate their own attractiveness and showed their photographs to others to rate, as well.
"High-estradiol women were considered significantly more physically attractive by themselves and others," Durante and colleagues wrote.
The high-estrogen women also reported more sexual behavior -- especially outside of a relationship, although it was not linked to one-night stands.
"Our results are consistent with the possibility that highly fertile women are not easily satisfied by their long-term partners and are especially motivated to become acquainted with other, presumably more desirable, men," they concluded.
The findings fit in with many other studies showing that hormones influence the behavior and success of both men and women. Earlier this week, U.S. and British researchers showed that male financial traders whose finger lengths indicate high testosterone levels in the womb made more money.

雌激素，即所谓女性激素，影响生殖能力并且使女人穿着更性感，行为上更追求刺激。
奥斯汀（德州首府）的德克萨斯州大学的Kristina Durante博士及其同事发现当年轻女性处于高雌二醇水平时，她们感觉自己更有魅力，并且她们依照这种感觉行事。
“高雌二醇的妇女更喜欢调情、接吻和与原有爱人以外的人发生恋情，并且似乎更喜欢约会其他男人。”Durante的团队在英国皇家学会期刊生物书简上写道。
“得到的结果支持生理上的美与生殖力之间的关系，并且提示生殖能力较强的女性是是一夫一妻制的机会主义者——即对婚外恋持开放态度，当更好条件的男性出现时即跳转到一段新的关系中。”
Durante的团队测试了52名年龄在17至30岁之间不使用激素类避孕药的女性。由于荷尔蒙水平在一周与另一周之间有所波动，他们从每个人那里采取了两份雌二醇样本。
他们要求受试者评估自己的吸引力并且将她们的照片交给其他人评估。
“高雌二醇的女性生理上明显更加有吸引力，无论是她们自己和其他人都这样认为。”Durante和她的同事们写道。
高雌激素的女性报告了较多的性行为，尤其是一段关系以外的那种，但与一夜情没有关联。
“我们的结论是：高生殖能力的女性不易被她们的长期伴侣所取悦并且喜欢结识其他更好的异性。”他们总结到。
这个发现与其它许多研究一样得出荷尔蒙影响着人的行为和成功，无论男女。本周早些时候,美国和英国的研究者们得出在从事金融行业的男性中,那些手指的长度能够提示他们宫内高睾酮浓度的男性比其他人赚的钱更多。 首次在此尝试翻译，多有不当之处，恳请各位指正。
