How did menopause change from being a natural (and often welcome) end to a woman's childbearing years to a deficiency disease in need of medical and pharmacological intervention? As she traces the medicalization of menopause over the last 100 years, historian Judith Houck challenges some widely held assumptions. By examining the history of menopause over the course of the twentieth century, Houck shows how the experience and representation of menopause has been profoundly influenced by biomedical developments and by changing roles for women and the changing definition of womanhood.
