The relationship between the ovulation cycle and 17β-estradiol level with the preferences of women to male partners

Recent research presented two competing theories on female preferences for outgroup members as prefered sexual partners. One line of research points to an increased female intergroup bias in mating contexts while the other demonstrated preference for strangers near ovulation. The former hypothesises that the bias could stem from the historical danger of sexual coercion, while the latter proposed the preference for strangers might reflect the need for increased genetic diversity. To tease out the effects of both the threat of and potential genetic benefits of outgroup membership, a sample of 111 normally cycling women evaluated a total of 20 images of both Croatian and Spanish men on attractiveness, suitability as long - term and short - term partners along with their physical formability. Their ovulatory cycle phase was assessed by measuring luteinizing hormone (LH) in urine. Independent raters previously evaluated the included images on attractiveness, dominance, strength along with their stereotypical Croatian or Spanish phenotype. The results further enlighten how the preferences across menstrual cycle are influenced by both formability and cues of outgroup membership.
