Women who experience menopause after the age of 40 are considered normal, and the vast majority of women go through menopause between the ages of 45 and 55. The average age of menopause in our country is 49 and a half years old, and it varies because of individual differences. The general age of menopause is related to family history, for example, if the mother has early menopause, she will also have early menopause as a child. The age of menopause is also related to the age of menarche. If the age of menarche is younger, the age of menopause will be earlier. Because a woman can ovulate about 400 eggs in her lifetime, which takes about 30 years, the age of menopause will be earlier if she menstruates early, and later if she menstruates later.
