There are many factors that influence female attraction towards men, and many of them are driven by women’s menstrual cycle. Sexual attraction in females has been shown to increase during the ovulatory phase of the menstrual cycle, which is the period of most fertility (Gangestad & Thornhill, 1998). Evolutionarily, this time is beneficial because it would be more likely for a female to conceive if she were more prone to attraction towards men during her fertile period. It has also been shown that female mate preferences change across the ovulatory cycle. Men with particular attributes, such as facial symmetry, are preferred during the period of most fertility (Gangestad & Thornhill, 1998). This can be explained by the Ovulatory Shift Hypothesis, first proposed by Gangestad and Thornhill (1998). Gangestad and Thornhill (1998) make three predictions within this hypothesis. This first prediction includes the ‘good genes principle,’ that women are attracted to certain attributes that signify that a male has “high genetic quality” (Gildersleeve, Haselton, & Fales, 2014). This could mean that a certain individual possesses genes that would increase an offspring’s’ fitness and, therefore the parent’s fitness, or do not possess genes that would be harmful to an offspring. Therefore, theoretically, if a female were more attracted to a male based on the male having high quality genes, she would more likely conceive an offspring with that individual. This would, in turn,
