Since 1972, Clinical Gynecologic Endocrinology and Infertility has been the most widely read book on gynecologic endocrinology and infertility in the world. This book is not so much a reference as a collection of clinical diagnoses and management principles, with a basic science foundation. Chapters emphasize approaches that have demonstrated measurable clinical benefit. Information is presented in four parts: reproductive physiology, clinical endocrinology, contraception and infertility.
