Policystic Ovary Syndrome (PCOS) is one of the most common endocrinological disorders in women of reproductive age, with an incidence of 6% to 7%. There are genetic, environmental and behavioural factors found to be responsible for this. High levels of male hormones (androgens) in blood, ovarian dysfunction and metabolic abnormalities are the main determinants of PCOS.
Genetic factors account for PCOS runs in families. A mother with PCOS can pass the disease to daughter (24%) and incidence of PCOS among sisters is 32%.
Lifestyle and environmental factors: a substantial proportion of women with PCOS are found to be overweight; many are obese. Increased fat deposition due to lifestyle changes is thought to be a contributing factor. Impaired insulin metabolism remains central to the metabolic pathophysiology of PCOS. Dysfunction of gonadotropic axis arising out of hyperinsulinaemic insulin resistance lead to anovulation and hyperandrogenism.
