Starting of periods in a girl depends upon both environmental and genetic factors. Average age at which girls get their first periods is different in different regions of the world. In USA, it is 12.5 years and in Asian countries, it is 11 years. First periods in a girl life are always without ovulation. Ovulatory periods usually start 3 months to one year after getting first ever periods. On average, a women has 400 cycle in her life and anovulatory periods again start in premenopause age. Premanopause age is also different in different regions of the world. It can vary from 42 to 49 years in different countries of the world.
