As of this post, three of the 20 comments on this story conjecture that obesity plays some role, and a full half of the comments are on subthreads discussing this hypothesis.

Interesting because I've never heard this hypothesis before and other online discussion of this article does not mention obesity.

It's also a bad hypothesis because the article is talking about changes that occurred over the last 10 years, and childhood obesity rates (including teenagers) have stabilized over the last 10 years.

It seems a little silly to me. Especially because when we talk about obesity, most people visualize morbid obesity. There are plenty of textbook definition "obese" people who can still attract mates.

I think the point is that obesity causes infertility....
