Generally, after the age of 40, it is a period ending with the irregularity of menstrual bleeding and the subsequent discontinuation of menstrual bleeding, which is seen in the period up to about 55 years. Menopause means the last menstrual bleeding. If menopause occurs before the age of 40, it is called early menopause. Menopause can be experienced without any discomfort other than the symptoms it should have. However, the number of women who have undergone this period is only one quarter.
