Menarche(say âMEN-ar-keeâ) is the first menstrual flow or menses of a woman. It marks the beginning of fertility, that is, your ability to become pregnant. Menopause marks the end of menstrual flow, usually after about 30to 40 years of monthly menses.
According to Tanner, the average age of menarche dropped from about 17 to 12.8 during the period 1830-1962. The rate of decline was 4 months per decade. Tanner has also noticed a decline in the age of initiation of the growth spurt. The trend seems to have stopped, with the age of menarche leveling off at 12.6.
