Abstract
Women who are regularly cycling exhibit different partner preferences than those who use
hormonal contraception. Preliminary evidence appears to suggest that during pregnancy
women’s partner preferences also diverge from those prevalent while regularly cycling. This
is consistent with the general assertion that women’s mate preferences are impacted by
hormonal variation. During pregnancy women’s preferences are thought to closely resemble
those displayed by women who are using hormonal contraception. Here, based on this
literature, we compare levels of sexual desire among pregnant women who met their partner
while using hormonal contraception and pregnant women who met their partner while
regularly cycling. We predicted that women who met their partner while using hormonal
contraception would experience higher levels of in-pair sexual desire during pregnancy since
these women will have partner preferences that more closely match those prevalent at the
time of their partner choice. Our results provide support for the idea that previous
contraceptive use/non-use may impact subsequent sexual desire for the partner during
pregnancy. Pregnant women who met their partner while using hormonal contraception were
shown to have higher levels of in-pair sexual desire than those who met while regularly
cycling. In contrast, levels of extra-pair desire were not related to previous use/non-use of
hormonal contraception. These findings were robust when controlling for a number of
relevant individual difference variables known to impact sexual desire. Our results thus
provide a more fine grained understanding of factors affecting relationship functioning during
pregnancy.
