|Abstract:||Research on within-subject changes in women’s intrasexual competitiveness has generally focused on possible relationships between women’s intrasexual competitiveness and estimates of their fertility. While this approach is useful for testing hypotheses about the adaptive function of changes in women’s intrasexual competitiveness, it offers little insight into the proximate mechanisms through which such changes might occur. To investigate this issue, we carried out alongitudinal studyof the hormonal correlates of changes in intrasexual competitiveness in a large sample of heterosexual women (N=136). Each woman provided saliva samples and completed an intrasexual competitiveness questionnaire in five weekly test sessions. Multilevel modeling of these data revealed a significant, positive within-subject effect oftestosteroneon intrasexual competitiveness, indicating that women reported greater intrasexual competitiveness when testosterone was high. By contrast, there were no significant effects ofestradiol,progesterone, estradiol-to-progesterone ratio, orcortisoland no significant effects of any hormones on reported relationship jealousy. This is the first study to demonstrate correlated changes in measured testosterone levels and women’s reported intrasexual competitiveness, implicating testosterone in the regulation of women’s intrasexual competitiveness.|
