- Women’s attraction to men is influenced by chemical factors that men give off. Women tend to prefer scents of men with different immune system genes than their own (which is good for their offspring).
- Ovulation affects men’s and women’s partner preferences.
- Women on the pill no longer desire the “masculine” and genetically favorable men they would normally be attracted to during ovulation. Once they come off the pill women may no longer be as interested in the “less-masculine” men that they chose while being on the pill and as a result may have affairs.
- Women who share immune system genes with their partner are less sexually responsive to their partner.
- Men smelling women’s T-shirts were less attracted to women on birth control pills.
- Male lemurs were less attracted to female lemurs after the female lemurs were injected with a long acting contraceptive.
This article provides a strained extrapolation of results from disparate studies (in different species) to weave a thesis: using birth control pills might mess up your romantic life, your family life and your children.
