Diagnosis and Management of Polycystic Ovary Syndrome is a comprehensive clinical reference work for primary care physicians, internists, general endocrinologists, obstetricians, gynecologists and students. PCOS is a common but frequently misdiagnosed disease. Many symptoms can be alleviated by early intervention and effective management.

Prominent endocrinologists are gathered to detail current research and treatment in this metabolic disorder, affecting a growing population. The chapters are comprehensive, providing cutting edge knowledge on pathogenesis, manifestations, diagnosis and treatment of PCOS. Each chapter will be concise concluding with cogent practice points.

The variety of medical issues presenting in PCOS patients result in late referrals or in- appropriate advice. This title will be a tool in a further understanding of the metabolic and genetic basis of PCOS, while providing management strategies.
