The Fourth International Congress on the Menopause was held in Lake Buena Vista, Florida, USA in October - November 1984. It was different from the previous meetings held under the auspices of the International Menopause Society in three respects: the duration of the Congress was extended to five days, plenary sessions were held on each day, and the scope of the subject matter was expanded to provide a total or holistic overview of the subject - hence the theme for the Congress 'Climacteric Medicine and Science: A Societal need. ' In recent years there has been an increased interest in the menopause and middle year aging by scientists and clinicians in fields as diverse as anthropology, urodynamics, nutrition and exercise physiology, while 'newer' issues in clinical medicine, such as osteoporosis prevention and management, attracted specialists in nuclear immaging techniques and internal medicine. Over 120 invited speakers plus numerous contributors to the free communication, special lectures and the poster sessions provided a virtual cornucopia of information on the menopause, that has indeed brought a newer perspective to a subject previously the domain of a single specialty, the gynecologist, and dominated by a single therapy, estrogen replacement.
