The primary aim of the current study will be to assess the effects of DHEA therapy in naturally menopausal women on sexual function using the Sabbatsberg Self-Rating Scale (SSS) over 12 months in a randomized placebo controlled trial. In addition the effects on well-being will be assessed by the Psychological General Well-Being (PGWB) Index and menopausal symptoms will be evaluated by the Menopause Quality of Life (MENQOL) Intervention Questionnaire. A diary record will also be employed to assess the effects on sexual function. Safety will be assessed over the entire study. Participants will also undergo a transvaginal ultrasound (TVU) at the beginning and end of the study, to determine whether DHEA affects the endometrial lining.
