I also have unusual levels of testosterone and found the following in a website (http://www.gynob.com/pcos.htm
Recent advances in understanding this disorder have demonstrated other problems besides alterations in the menstrual cycle and ovulation. For one thing, there's a certain tendency toward diabetes with a phenomenon called "insulin resistance." It's not that there's too little insulin, but that the insulin made is not as good. Therefore, handling sugar is impaired. The body responds by making even more insulin, and the extra insulin tends to stimulate other tissues that normally aren't particularly responsive to insulin. One of the tissues is the ovary, which is stimulated to make extra androgen (testosterone). Other effects on other tissues include:
stimulation of the lining of blood vessels, causing hypertension;
effects on the liver and on cholesterol metabolism, contributing further to heart disease;
and a decrease in sex hormone-binding globulin (SHBG), which means less sex hormone is bound ("tied up") and therefore free to act.
The "bound up" testosterone is fairly unreactive. The free testosterone is what has the classical male hormone-like effects, like hair growth, acne, and disruption of the normal ovulation and cycling. There accumulates a collection of early follicles that don't go any further. (An ovary in such a state is, however, "loaded" such that there is an exaggerated response to induction of ovulation with a greater risk of twins and triplets from multiple simultaneous ovulations.)
The "full-blown typical" PCOS patient has a history of only occasional ovulations (<8 per year) and prolonged cycles of greater than 35 days, male-like hair distribution or hair loss, obesity, multiple ovarian cysts, acne, and laboratory assessment demonstrating too much testosterone. But there are varying degrees of PCOS, and many women with it have only few or isolated aspects of the disorder.
Hope that helps!!
