�A well-publicised experiment previously showed that women choose body olfactory perception of hands who ar genetically dissimilar to themselves. In contrast, contraceptive pill-users preferred comparatively similar workforce.
If pill-use alters preferences and pick of collaborator, resulting between-partner genetic law of similarity could suit fertility issues, but the difference might alternatively be due to unrelated differences between pill-users and non-users.
We tested this directly, comparing women before and after initiating pill-use.
Although women did not prefer dissimilar hands overall, pill-use did wobble preference towards genetically-similar odours. If olfactory property influences human mate alternative, our results suggest that contraceptive pill-use could interrupt natural first mate preferences.
