context: Distinguish between natural and artificial menopause. Natural menopause is associated with age-related depletion of the ovarian follicle supply. It usually occurs between the ages of 45 and 55 years, but may be early (40–45 years old) or late (over 55 years old). In the event of menopause before age 40, they speak of ovarian exhaustion syndrome. Artificial menopause can be caused by surgical removal of the ovaries, radiation or drug exposure.
