I am dealing with this condition right now, or if not this, then something else to do with low progesterone/high testosterone. I am losing a lot of hair and I have menstrual irregularity and some body acne. I have been seeing a naturopathy doctor who prescribed a battery of herbs and supplements. From what she told me, my problem stems from a pituitary problem which affects the liver and ovaries, hence hormonal imbalance. Here are the highlights from the list:

Low fat/low glycemic index diet
Exercise
Plant derived progesterone at a certain time in my cycle to stimulate the ovaries
Vitex
Vitamin B6
Inositol
Serenoa
Flax

I have been doing some reading on pcos and I think it's based on some strange and dubious science, or at the very least most doctors don't know enough. Even my naturopathic doctor says they're starting to call and characterize it as something else. So I would say, definitely seek professional help from specialists. I am optimistic about my treatment, but I haven't begun it yet so I can't say offhand. I have read about reproductive endocrinologists, hair loss specialists, the whole gamut. I suspect you may end up trying a number of specialists until you find one that works. But also, look up your local naturopathist if you are looking for natural/holistic treatments.

I have been looking up information on low glycemic diets.
