Answer:
Girls start menstruating at the average age of 12. However, girls can begin menstruating as early as 8 years of age or as late as 16 years of age. Women stop menstruating at menopause, which occurs at about the age of 51. At menopause, a woman stops producing eggs (stops ovulating). Menopause is defined as one year without periods, and after this time a woman can no longer become pregnant.
