Women Use Sexier Body Language To Indicate Ovulation And Fertility – Women Dance And Walk Sexier
Much debate has occurred about ovulation in human women. It was postulated that because it was not obvious to onlookers, that is was “hidden,” or “concealed.” As new research showed that women, during peak fertility, smelled better and their voice pitch improved, as well as morphological changes including improved face shape and a slew of other behavioural changes, ovulation was determined to be far from concealed, but still lie somewhere in between that and totally exposed.
The Current Study
German researchers Bernhard Fink, Nadine Hugill and Benjamin Lange, University of Göttingen, Germany have added even more evidence using nonverbal communication to show that women undergo specific changes during oestrus that help them stand out against non-fertile women.
The specific hypothesis was that “men would rate women’s dances and gaits higher on attractiveness during their late follicular (‘fertile’) phase than during their midluteal (‘non-fertile’) phase, thus arguing that female body movements may serve as a potential cue to ovulation.”
A group of 48 heterosexual women were recruited for the study. Each was not using hormonal contraceptives, was non-pregnant, nor lactating. Women reported menstrual cycle length of 26-30 days and were assessed in the study at a low and then high fertility period of their cycle. To assess peak fertility, the researchers used a back counting method were ovulation is predicted to occur 14 days prior to the onset of menses. The ‘fertility window’ was therefore defined as a 6 days period (5 days preceding the day of ovulation including the actual ovulation day). The ‘non-fertile’ window included the days between the 19 and 24 (mid-luteal phase). Fertility is rather brief, typically lasting only 2-3 days and shows a steep increase 1-2 days before ovulation and then declining sharply thereafter.
As part of the experimental procedure the women wore a black t-shirt, tight fitting pants and socks and tied back their hair. Two dances were recorded over the same pop song for 30 seconds. The dancing video clips were converted to outline of the body to highlight the movement.
Gait was also assessed by walking in a straight line towards the camera, followed by turning around at a fixed point, before walking back to the starting point. This was repeated 6 times.
Men reported that women’s dances were much more attractive during the fertile phase over the luteal (non-fertile) phase. Additionally, men also judged women’s walk to be more attractive in the fertile phase, than the non-fertile phase. Men rated women’s walk to be much sexier during their fertile phase than their non-fertile phase. In fact women’s gaits (their walk) had twice the effect of their dance, suggesting that women’s fertile walk is a far stronger indication of fertility than her dance.
Overall, the results indicate that men are perceptually capable of discerning between low and high fertility based on women’s body language alone.
Discussing The Findings
This study forms the link between previous research which has assessed specific changes including odor and morphological changes (the face and skin texture) in women due to ovulation by connecting them to behavioural changes.
For example, a prior study of lap dancers revealed that women who cycle normally receive greater earnings overall and also increased earnings at around peak fertility.
Now we understand the reason for this – they behave more seductively!
This is also congruent with other research on ovulation including seductive changes to odor, voice pitch, styling (wearing more revealing and provocative clothing), changes in face shape and skin texture, and so forth.
As far as this research is concern, it is one of the more definitive of its kind as it isolates other factors such as odor and face shape from actual behaviour. Women around peak fertility show more sexual body language. They move differently than women who are currently non-fertile.
Not only this, but men notice!
When women are fertile, they move in ways that draws the attention of men. In most cases, one would assume that these movements are not conscious, but likely rely on hormonal fluctuations driving associated behavioural changes. When women are fertile, their bodies send out hormonal signals, and their body responds by acting more sexually overt. By extension, the results are an increase in attracting male attention.
