What do women desire? All depends on the date!

If a woman loves you, you do not like, do not blame the notorious fortune-telling on a camomile. Listen to advice of scientists – the evolution of the blame!

The researchers analyzed a lot of work on the topic of how women’s preferences change in the choice of a partner during the menstrual cycle. The results make it possible to assume that due to the evolution of women during ovulation tend to choose men who have the most pronounced sexual traits – such as the masculine body and face, dominant behavior and certain smells. However, these features are not typical for men, they are opting for long-term relationships.

But it is not the whole month she gives preference when choosing a partner masculine traits that probably is an indicator of high-quality genetic material in the ancestors of modern men. It lasts only a few days of the cycle when the woman is most likely to pass on their genes to offspring. Hundreds of thousands of years ago, it has increased its chances of survival and the ability to leave heirs.

“Sometimes a woman may acquire notoriety windy persons, but the changes they are experiencing – not their whim,” – says Marty Hazelton, Professor of Psychology and Sciences of the Communication and the main author of the article. “Women experiencing complicated and confusing changes in their preferences, although in our time, they no longer have a special functional significance.” The results are published in Psychological Bulletin magazine, published by the American Psychological Association.

Preferences of women in the choice of partners in the period of high fertility rates were a subject of controversy since the 1990s, when the first studies were carried out to confirm this hypothesis. Since then, in several studies could not replicate the results of the first study, which was the reason for the doubts about the idea.

Hazelton and Kelly Gildersleeve, doctoral candidate of psychological sciences and the study’s lead author, spent three years trying to resolve these contradictions. They got the data of many scientists involved in this problem, transferred data fifty studies in the same mathematical format, in order that they can be jointly analyzed.

In most scientific papers obtained were statistically significant data on the changes in the women’s preferences.

However, the study does not say so clearly what it is male characteristics are most attractive to women during ovulation. According to Hazelton, women’s reaction to the features of the male body is likely to have the greatest value.

In several experiments, researchers asked women to smell T-shirts worn by men with varying degrees of symmetry of the body and face. (According to the results of many studies on animals, such symmetry is associated with a large body size, more eye-catching sexy “ornaments.” – Such as bright colors male birds, as well as better health Thus, it was suggested that the symmetry of the face and body can be an indicator of high-quality genes). Women in the ovulation period, preferred the scent of men with greater symmetry. This meta-analysis also showed that women prefer the smell of men with a higher body symmetry, although further research is needed to understand how this phenomenon is strongly expressed.

Hazelton – one of the pioneers in the study of behavioral changes during ovulation. One of her works has shown that women who feel their partners are not particularly sexy, are more prone to attraction to other men during ovulation than those who think their men are very sexy.

“Marty excellent reputation among researchers in this field, as well as its deep understanding of the complexities of studying the process of ovulation makes it an ideal candidate to carry out this very ambitious project,” – said Gerry Simpson, a professor of psychology at the University of Minnesota. “Her extensive knowledge in this area, as well as the fact that she and her colleagues were able to identify the signs of men who prefer women in different periods of the ovulatory cycle, making it truly a very important study.”

Have changes in sexual preferences among women may be controversial, but changes in sexual preferences and behavior are well known and understood in mammals, from rats to orangutans. For example, chimpanzees females prefer to have more contacts with various sexual males during the fertile phase than outside it. It is believed that this strategy helps them to increase their chances of survival.

“Until the last decade, we all agree that female sexuality is radically different from all other animals sexuality that unlike them, in women it is somehow independent of the reproductive hormones”, – says Hazelton. “And then a whole series of research results challenge our traditional views.”

One of the hypotheses to explain the occurrence of changes in the choice of partner, argues that this behavior may be an evolutionary adaptation. This adaptation helped our ancestors to leave and save the offspring long before the advent of modern medicine and sanitation, which made it possible to significantly reduce child mortality. “According to this hypothesis, women choose certain masculine traits in the ovulation period, were more likely to pass on to their children the best genetic qualities, thus increasing the chances for children to survive and their offspring,” – says Gildersleeve.

In his previous work, Hazelton suggested that being between two types of male partners may also be due to the importance of adaptation mechanisms. According to this “double hypothesis partners” in a stable environment ancient woman gave preference to such qualities as kindness, reliability and availability of resources (so-called “quality of a good father”), but both were important sex appeal and a male character ( “sexual quality”), even if the two sets were aligned in the same person.

“Predecessor of modern women really won in the choice of a man with the qualities of a good partner, as well as with signs showing the high quality genetic material – brave face and figure,” – says Hazelton. “Women can have the best of both worlds – the contribution of the father of a partner in long-term relationships and excellent genetic material from temporary partners. However, this is true only if the temporary partners met at some point in the cycle of high and if female fertility affair remain secret.

Another hypothesis is that the Hazelton and Gildersleeve also find plausible to suggest that the changes in women’s preferences during the menstrual cycle served for adaptation even before the people. In humans, they are rudimentary, such as the coccyx, or “tail bone”, which has been preserved at the end of a human spine. These vestiges are present in modern humans, despite the fact that do not perform no apparent function.

In any case, scientists believe the benefit of the study of women’s preferences and their dynamics. “If women understand the logic of this process, they will be better able to control the decision-making sex. For example, if a woman suddenly realizes that a guy keen to work, it does not necessarily mean that it does not have a nice man for long relations “, – says Hazelton. “She just hears fleeting echo of the past.”

Despite its independence and autonomy, women today still in some degree subject to older strategies of behavior they should know about it and be able to control himself at the right moment.
