Menopause
Menopause typically occurs between 49 and 52 years of age. The majority of women have their last period between the ages of 48 and 55. The average age of the last period in the United States is 51 years, in the United Kingdom is 52 years, in Ireland is 50 years and in Australia is 51 years. In India and the Philippines, the median age of natural menopause is considerably earlier, at 44 years. The menopausal transition or perimenopause leading up to menopause usually lasts 7 years (sometimes as long as 14 years).
International Menopause Society
The Society's official journal, "Climacteric", the Journal of Adult Women's Health and Medicine, was founded in 1998 and is listed in Index Medicus/MEDLINE. The editors-in-Chief are Anna Fenton (New Zealand), and Nick Panay (United Kingdom). It publishes international, original, peer-reviewed research on all aspects of aging in men and women, especially during the menopause and climacteric. The content of the journal covers the whole range of subject areas relevant to climacteric studies and adult women’s health and medicine, including underlying endocrinological changes, treatment of the symptoms of the menopause and other age-related changes, hormone replacement therapies, alternative therapies, effective life-style modifications, non-hormonal midlife changes, and the counselling and education of perimenopausal and postmenopausal patients.
