The influence of hormone replacement therapy on mating psychology among post-menopausal women

- We investigated HRT influences on mating psychology in post-menopausal women.
- HRT users reported increased sociosexual orientation and desire for extra-pair mates.
- HRT use was not associated with relationship behaviors, or masculinity preferences.
- Results suggest HRT affects sexual desires and attitudes in post-menopausal women.

Hormone replacement therapy (HRT) is a popular treatment for menopause-related symptoms and is associated with increased well-being and sexual function. Researchers have investigated the effects of synthetic hormones within hormonal contraceptives on preferences for masculine men, and on behaviors directed towards male partners. Yet, no studies have examined the impact of synthetic hormones in HRT on mate preferences or mate-directed behavior among post-menopausal women. Here we tested the influence of HRT on women's reported sexual motivation, partner-directed behaviors (i.e., jealousy and mate retention behaviors), and mate preferences. Post-menopausal women (N = 213) responded to an online survey and completed a two-alternative, forced-choice face preference task where they rated the attractiveness of male images manipulated in sexual dimorphism. We found that HRT use was positively associated with sexual satisfaction, attitudes towards unrestricted sex, and sexual interest towards extra-pair men. There were no differences between users versus non-users in partner-directed behavior or masculinity preferences. This study highlights the need for further investigations into hormonal influences on mate preferences and behavior among post-menopausal women.
