Hormonal birth control use and relationship jealousy

FRESH and NEW paper
Cobey, K. D., et al. "Hormonal birth control use and relationship jealousy: Evidence for estrogen dosage effects." Personality and Individual Differences (2010), doi:10.1016/j.paid.2010.09.012

".... this study supplements the existing literature which suggests that hormonal oral contraceptive pill use may influence female mate choice preferences and relationship dynamics. For example, evidence indicates that, relative to non-pill users, women on Combined oral contraceptives (COC) show no or weaker preferences for masculine faces and voices and a decreased preference for genetic dissimilarity in partners. It may be that pill-associated changes in preferences for masculinity and genetic dissimilarity are mediated not just by the absence of an estrus phase but also by COC ethinyl estradiol and progestin concentrations."

Please also read the post "Innovations: to take the 16PF5 test 3 times"

I think women will love a rational explanation of why they need to take the test 3 times.
A Marketing campaign should be incisive in this new discovery:
contraceptive hormonal methods alter mate choice in humans because only short-term but not long-term partner preferences tend to vary with the menstrual cycle.
