Answer 1

It's defined as the final menstrual period and is confirmed when a woman has not had her period for 12 consecutive months. Women in North America will likely experience natural menopause between ages 40 and 58, averaging around age 51. Some women, however, reach this phase in their 30s, others in their 60s.
