Advances in the treatment of polycystic ovary syndrome

Current treatment of polycystic ovary syndrome (PCOS) in women is essentially symptomatic. However, there is growing evidence that this disorder is an evolving condition and that it may be associated with major medical outcomes later in life. As a consequence, effective treatments should be instituted as soon as PCOS is diagnosed. Insulin resistance with associated hyperinsulinaemia and increased luteinising hormone (LH)-dependent androgen secretion from the ovary seem to play a central role in the pathogenesis of PCOS. Accordingly, the effects of attenuation of hyper-insulinaemia, LH excess or hyperandrogenism were recently assessed, with promising results. A consistent finding was that attenuation of insulin resistance and hyperinsulinaemia may correct the entire spectrum of endocrine, metabolic and reproductive abnormalities of PCOS in many subjects.
