Study: Women's hormonal cycles do not affect preferences for men's behavior

In the past, there has been much excitement over research that purported to show a link between changes in women's cycle and their degree of sexual attraction. However, new research at the University of Göttingen using the largest sample size to date questions previous results. The new research shows that shifts in women's cycles did not affect their preferences for men's behavior. The researchers found, however, that when fertile, women found all men slightly more attractive and, irrespective of their hormone cycle, flirtier men were evaluated as being more attractive for sexual relationships but less attractive for long-term relationships. The results were published in Psychological Science

According to the good genes ovulatory shift hypothesis (known as GGOSH), women's preferences for certain behaviors, presumed to indicate men's genetic fitness, should differ according to their fertility. To test this, the researchers studied 157 who met strict criteria—including being 18 to 35 years old, heterosexual and having a natural, regular . The participants watched videos showing a man getting to know a woman who was out of frame. In four separate testing sessions, the female participants rated the men on sexual attractiveness for a short-term relationship without commitment, and on attractiveness for a long-term . The participants were asked to focus on the way the men behaved. The researchers used saliva samples to analyze current hormone levels and highly sensitive urine ovulation tests for validating the ovulation date, and in particular, the fertile period.

The researchers found there was no evidence that a woman's mate preference changes across the ovulatory cycle. Rather, women seem to perceive or evaluate every man as slightly more attractive when fertile compared to other cycle phases. They also found that men who act in a more competitive manner and show more courtship behavior (for instance, flirting) were evaluated as being more attractive for short-term sexual relations but less attractive for long-term relationships, independent of cycle phase or hormone levels.

First author Dr. Julia Stern from the University of Göttingen's Institute of Psychology said, "There is a lot of research on women's mate preferences, so at first we were surprised that we didn't see the same effects. However, our new results are in line with other recent studies using more rigorous methods than previous studies. The finding that ratings of attractiveness increase in the fertile phase, independently of men's behavior, is new, and indicates that women's mating motivation is likely to be higher in the fertile phase."

Apart from using a large sample that met strict criteria, the researchers followed rigorous methods, for instance, by preregistering their study before data collection and employing "open science" practices such as making their data and analyses publicly available.
