There are multiple causative factors in the pathophysiology of PCOS including genetic predisposition, environmental factors, obesity (abdominal type), sedentary life style etc. Hyperinsulinemic insulin resistance plays a prominent role in PCOS. hyperinsulinemia produces a hyperandrogenic state (excessive levels of male sex hormones such as testosterone).
