Polycystic ovarian syndrome (PCOS) is classically characterized by the clinical triad of androgen excess, anovulation infertility and obesity. Anovulation occurs due to functional ovarian and/or adrenal hyperandrogenism. The etiology and patho physiology of PCOS is unknown .Proposed theories include excess of gonadotropins; the effect of which is amplified by disturbances in intrinsic regulatory peptides, such as inhibin or extrinsic regulatory peptides, such as insulin or insulin like growth factor ( IGF). For over 25 years insulin resistance has been known to be associated with PCOS. Improvement in insulin resistance with the use of insulin sensitizers, such as metformin and thiazoldinediones (TZDs) have been seen to be associated with better ovulation and reduced testosterone levels in patients with PCOS. Aims: The aim of the present review is to discuss the new concepts in the pathogenesis of PCOS and to know usefulness of insulin sensitizers in such patients. Methods: Over 50 articles extending the span of more than 25 years have been reviewed and an attempt has been made to know the etiopathogenesis of PCOS and also to assess the validity for the uses of insulin sensitizers in patients of PCOS. Results: With the advancement of knowledge regarding etiopathogenesis, the management of PCOS has changed in recent years. In view of positive association between hyperinsulinemia and PCOS, improvement in insulin resistance through weight loss and use of insulin sensitizing drugs has been recommended. Conclusions: Besides symptomatic treatment, recent studies recommend use of insulin sensitizers in management in PCOS for better outcome in them. Key words: Polycystic ovarian syndrome (PCOS), Insulin resistance (IR) Insulin sensitizers (IS).doi:10.3126/njog.v3i1.1431 NJOG 2008 May-June; 3(1): 3 - 9

The endocrine system is the group of glands that secrete hormone directly into the circulatory system moves towards distant target organs and affects them. This system release hormones that help control many important body functions. Dysfunctioning in the endocrine system may develop many disorders like diabetes, thyroid, growth disorders and sexual dysfunction. Poly cystic ovarian syndrome is one of the common endocrine disorder. PCOS is a common condition that causes a range of symptoms including irregular periods, unwanted hair growth, acne and weight problems. Increased circulating levels of testosterone can be considered as the major cause of development of polycystic ovarian syndrome. It is a male hormone, but women’s bodies make it too. Higher than normal testosterone level, makes women to experience PCOS. The physicians target on regular menstruation. In order to maintain the regular periods physicians basically administer Estrogen and Progesterone injection. Metformin is used during PCOS to treat insulin resistance developed in those women. Insulin resistance means that their bodies do not respond well to the hormone insulin that controls blood sugar levels. This causes blood sugar level to rise and this may lead to greater production of testosterone. Corticosteroids, vitamins, contraceptives pills are also prescribed for symptomatic treatment of PCOS. Changing of lifestyles may greatly help in management of poly cystic ovarian disorder. Regular exercise and weight management is the key for complete treatment of PCOS. This review contains all the information regarding PCOS.

Background: Ovarian androgen production can be promoted by insulin resistance which leads to reproductive abnormalities in Polycystic Ovarian Syndrome (PCOS). A wide variety of female tissues can synthesize and secrete Prostate Specific Antigen (PSA). Androgens may take part a significant role in PSA secretion in PCOS. As insulin resistance stimulates androgen production, the baseline value of PSA may decline by insulin sensitising agents in PCOS. Present study is an attempt to measure the function of PSA as a marker of androgen excess in PCOS and to assess the role of insulin sensitising agent metformin in altering PSA level in PCOS.Methods: The study was undertaken to assess the insulin resistance, testosterone and PSA level in 45 women diagnosed as PCOS and 45 healthy controls. Alteration of insulin resistance, serum testosterone and PSA levels by metformin was also analysed.Results: A significant increase in testosterone, PSA level and insulin resistance was observed in PCOS cases when compared with control (p<0.001). When metformin was given for 4 months, improvement in insulin resistance and testosterone level was found in cases, but PSA values observed no change. Correlation was not found linking insulin resistance with PSA level prior to and after therapy.Conclusions: Serum PSA level could be detected in high significant concentration in PCOS women. Various researches explain that insulin resistance and BMI may perhaps control serum PSA level, but our result demonstrate no effect of insulin sensitising agent on serum PSA value.
