That is a good point. The article doesn't discuss that possibility but if that is not the cause of the infertility, and I can't believe that the majority of women are obese because of PCOS, I still think the NHS decision is a wise one.

My wife has PCOS and I've been to medical conferences about it with her. I actually can believe that a lot of the woman who are obsese (especially those who don't eat huge amounts of junk food) do have PCOS. The estimates I've seen is that 5 to 10 percent of women of child-bearing age have PCOS to some degree. As someone else mentioned, thyroid problems can cause similar problems.
