Although endometriosis and adenomyosis are often assessed under the same umbrella, the epidemiology, clinical manifestations and management strategies of endometriosis and adenomyosis occur differently during the life cycle of a woman. Endometriosis can be diagnosed at many points across the lifespan, including adolescence and the climacterium, as well as pregnancy. Being associated with potential adverse health effects, different clinical presentations requiring different therapeutic approaches render it imperative to tailor management strategies for each period of the lifespan: in utero and early life, puberty and adolescence, reproductive years, pregnancy, late reproductive age, and the menopause. This book provides comprehensive insight into the general aspects, diagnosis and treatment modalities of endometriosis and adenomyosis in all stages of a woman’s life - a unique element of its approach. Thematic sections discuss the basics of diagnosis and management of both endometriosis and adenomyosis from birth through menopause, including aspects of fertility preservation, sexual dysfunction, psychological considerations and prevention. The current pharmaceutical approaches and efficacy are presented, including progestins, oral contraceptives, aromatase inhibitors and GnRH agonists and antagonists. The final section provides current practice guidelines for the management of both conditions as well as an investigation into future research and clinical strategies. Taking a truly global perspective, Endometriosis and Adenomyosis will be a valuable resource for reproductive endocrinologists, infertility specialists and obstetricians and gynecologists worldwide.
