Effects of menstrual cycle phase on ratings of implicitly erotic art

Abstract

Women's perceptions of and responses to explicitly erotic stimuli have been shown to vary across the menstrual cycle. The present study examined responses to implicit eroticism. A total of 83 women provided reactions to paintings by Georgia O'Keeffe in 6 day intervals over the course of 1 month. Among freely cycling women (n = 37), 31% of their descriptions included sexual themes during the first half of their cycle, dropping to 9% of descriptions in the second half. In women using oral contraceptives (n = 46), there was no significant difference in descriptions across the cycle (13% in the first half vs. 17% in the second half). Results were discussed in terms of evolutionary psychology and social-cognitive perspectives on the relationships between hormonal fluctuations and sexuality.
