The most obvious explanation is that only the "fittest" men get to have multiple wives in the first place. They'll tend to be richer, and rich men live longer.
The key thing is you have to be fit at something. Either physically or economically. Every man desires to bed as many women as possible. Most dont. This research will only make them feel miserable. It also assumes having as many women as possible is a good thing. The AIDS epidemic shows that is not the case.
