Menopause at age 45 is normal. Because the average age of menopause in our country is 49 and a half years old, most women menopause between 45 and 55 years old, because individual differences, so the age of menopause also varies, but menopause is related to family history, for example, their own mother menopause earlier, they will also menopause early. The age of menopause is somewhat related to the age of menarche, for example, if menstruation comes early, menopause will also come early, because women only have about 400 eggs to expel in their lifetime, if they have menstruation early, they will expel one egg every month, and the 400 eggs will be expelled in a relatively short time. If you get your period later, the 400 eggs will be finished a little later, so the age of menopause will be a little older.
