Phishbowl is absolutely correct. Metformin is often prescribed for folks with PCOS (I was treated with Met for years before I developed diabetes because I also have PCOS). According to the specialist I saw up to 60% of people with PCOS go on to develope type 2 diabetes. Both are dieases affecting metabolism and are endocrine system disorders. When I first started I was on the lowest dose of Met and also put on Aldactone (which is often prescribed for hypertension, PCOS and hormone balancing such as obtained with birth control pills). They eventually dropped the Aldactone (high liver enzymes and development of fatty liver) but not the Met.
I didn't know why it's prescribed either so I googled "PCOS metformin". Your question is NOT (yikes, I can't type fast. sorry) ignorant in the least! Anyway, here is one of the websites to look at. There are others. Sorry I can't help more.
