**1. Introduction to menopause**

Menopause is a normal physiological and natural event. The WHO defined menopause as permanent cessation of menstruation due to loss of ovarian follicular activities at the end of reproductive life. Menopause before the age of 40 years is considered as premature menopause or premature ovarian insufficiency.

The average age of menopause is 51 years, which is influenced by both genetic and environmental factors. Due to increased life expectancy of women, postmenopausal years cover more than one third of the total female life span.

Though natural events of estrogen deficiency of menopause herald a variety of potential problems that can affect the quality of life, specific concerns include subjective symptoms such as vasomotor instability, i.e., hot flushes, psychological and psychomotor disorders, menstrual irregularities, vaginal dryness, genitourinary dysfunction, and osteoporosis which have implications for longterm health [1–6].

So doctors and menopausal women both are interested in and deserve an understanding of the symptoms and the basis for therapeutic recommendation aimed at relieving symptoms and reducing subsequent health risks.
