This volume represents an up-to-date overview on the major areas of gynecological endocrinology, providing the reader with a complete explanation of female endocrine regulation and metabolism and relevant disorders and treatment. It is published within the International Society of Gynecological Endocrinology (ISGE) Series and is based on the 2013 International School of Gynecological and Reproductive Endocrinology Summer Course. The book covers a very wide range of topics – from primary amenorrhea to menopause, from the impact of ovarian surgery on fertility to fertility cryopreservation, from metabolic syndrome and polycystic ovary to premature ovarian failure and from the clinical impact of selective progesterone receptor modulators to the use of progesterone in prevention of premature labor. It will be an important tool for obstetricians and gynecologists, endocrinologists and experts in women’s health as well as interested GPs.
