What the study shows is that women on the Pill have a different sense of smell when it comes to sweaty T-shirts. That DOES NOT mean that they are choosing different men in real life from women who are not on the Pill. The story Meghan cited is either sloppy science or journalists who want a good headline. They have not even shown a link between actual dating habits and what kind of sweat smell you prefer for anyone.

If you want to prove anything about mate selection by women on the Pill, you have to take a group of single women and randomly put half on the Pill and half not. Then follow them for a few years and see if they manage to find mates and stay with them. If they did not, you could then speculate about why and see if it was linked to smells or not.

There is a tendency to find a scientific fact (women on the Pill have a different sense of smell and like a different kind of sweat) and extrapolate wildly and say the theory is scientific. The tendency often goes with a possible evolutionary explanation that is itself just an unprovable theory that could probably be argued the other way around. Anyhow, I don't think women on the Pill need to worry that they are incapable of choosing a husband.
