Does the strength of women’s attraction to male vocal masculinity track changes in steroid hormones?
Recent studies that either used luteinizing hormone tests to confirm the timing of ovulation or measured steroid hormones from saliva have found little evidence that womens preferences for facial or body masculinity track within-subject changes in womens fertility or hormonal status. Fewer studies using these methods have examined womens preferences for vocal masculinity, however, and those that did report mixed results. Consequently, we used a longitudinal design and measured steroid hormones from saliva to test for evidence of hormonal regulation of womens (N=351) preferences for two aspects of male vocal masculinity (low pitch and low formants). Analyses suggested that preferences for masculine pitch, but not masculine formants, may track within-woman changes in estradiol. Although these results present some evidence for the hypothesis that within-subject hormones regulate womens attraction to masculine men, we do not discount the possibility that the effect of estradiol on pitch preferences in the current study is a false positive.
