Don't give up finding a doc. Def puruse it. PCOS patients come in at least 5 ways... it doesn't mean you still don't have PCOS... and yes, for some patients insulin resistance is a part of it.
traditional PCOS -- anovulatory, increased androgens, no insulin resistance
endocrine syndrome X -- anovulatory, increased androgens, insulin resistance or type 2 diabetes
non-traditional PCOS --anovulatory, normal androgens, obese, insulin resistant or type 2 diabetes
non-traditional PCOS -- ovulatory, increased androgens, mild insulin resistance
idiopathic hirsutism -- ovulatory, increased androgens, no insulin resistance
The Inciid FAQ is a good starting point for the dx hurdles/tests.
