Polycystic ovarian syndrome, or PCOS, affects nearly five percent of all women and is characterized by excessive levels of androgens, particularly testosterone. Women with this condition commonly develop "cysts" on their ovaries as a result of disturbed ovary function. Although the cause of PCOS is unknown, a strong correlation exists between PCOS and insulin resistance, diabetes, and obesity. PCOS frequently causes infertility, irregular menstruation, and many symptoms related to high testosterone. Fortunately, Dr. Terlinsky can help you.
