the definitiOn Of menOpause

Menopause is the end of menstruation. The word comes from the Greek mens, meaning monthly, and pausis, meaning cessation. Menopause is part of a woman's natural aging process when her ovaries produce lower levels of the hormones estrogen and progesterone and when she is no longer able to become pregnant.
Unlike a woman’s first menstruation, which starts on a single day, the changes leading up to menopause happen over several years. The average age for menopause is 52. But menopause commonly happens anytime between the ages of 42 and 56.
A woman can say she has begun her menopause when she has not had a period for a full year
