A medical survey on menopause and its symptoms is underway in six regions of the country. Some women have committed suicide because they confused menopause with HIV/AIDS symptoms. Menopause is the time in a women's life when menstrual periods stop. This occurs when the ovaries naturally begin decreasing the production of sex hormones, oestrogen and progesterone. On average, women reach menopause at the age of 51 years although it can occur earlier between 30 and 40 years and much later at 60 years in some women. Most women, however, experience menopause between 45 and 55 years.
