Despite dizzyingly fast-paced advances over the past two decades, even the definition of polycystic ovarian syndrome (PCOS) remains in dispute. "Insulin Resistance and Polycystic Ovarian Syndrome: Pathogenesis, Evaluation, and Treatment" highlights the recent transition of PCOS from an infertility disorder with a diagnosis based on ovarian tissue histology to a more complex clinical entity, a metabolic disorder in which insulin resistance plays a central role. With an expert panel of authors, each chapter provides an up-to-date and balanced overview of PCOS, paying special attention to the central role of insulin resistance in the syndrome's pathogenesis and in the management of its reproductive and metabolic abnormalities. Comprehensive and thought-provoking, "Insulin Resistance and Polycystic Ovarian Syndrome: Pathogenesis, Evaluation, and Treatment" is an invaluable resource for endocrinologists.
