Polycystic ovary syndrome (PCOS) is a complex and heterogeneous disorder presenting a challenge for clinical investigators. It is the most common endocrine disorder of women in reproductive age, a multifaceted reproductive, cosmetic and metabolic problem, with an enigmatic pathophysiological and molecular basis.he genetic spectrum of polycystic ovary syndrome. The spectrum of evidence for PCOS genetic basis is very broad supporting the molecular basis of this abnormality but by no means is adequate to interpret the pathogenesis of the syndrome.
