Ah ha! I read this post before I joined up, then couldn't find it when I wanted to comment....
I *think* what it is saying is that it used to be an advantage to be able to have kids despite poor bodyweight. Only now, we're TOO good at storing body fat etc and it's messing everything up. But yes I think he is implying that "natural selection" will act (well, it WILL act unless we counter it, which we do for every person who ever has medical treatment anyway).
To the OP - I read it as PCOS *was* a good condition, but our environment has changed. Maybe they looked at cardiovascular / diabetes problems because PCOS has links with insulin resistance, abnormal blood levels of things...?
This is particularly interesting to me as I (try to) follow a "Primal / Paleo" type diet. If my metabolism is prehistoric, maybe my diet should be too!
I try not to take things like this personally, sometimes it is hard, but just think of all the poor men reading those "Men to die out in 50'000 years" articles...!
