The same interaction for odour pleasantness ratings bordered on significance ( F 1,83 =3.92, p =0.051), but there was no effect for odour intensity ( F 1,83 =1.06, p =0.307).

Importantly, this difference was apparent even before they initiated pill use, although we do not know the reason for this.
Relationship length was unrelated to MHC-odour preference, but among women in relationships, we found a near-significant association between MHC-odour desirability scores (but not pleasantness or intensity) and the frequency with which women reported fantasizing about sexual relationships with other men ( F 2,45 =2.68, p =0.080), such that women who did so more frequently gave higher desirability scores to MHC-dissimilar odours ( figure 3 b ).
