At first, cycles are anovulatory and may vary in length from 10 to 60 days or longer. As adolescence proceeds into adulthood, regular patterns of menstruation and ovulation are established at intervals ranging from 25 to 35 days. The length of the menstrual cycle varies considerably among women. The commonly accepted cycle average is 28 (27 to 30) days, with rhythmic intervals of 21 to 35 days considered normal. About 5 to 10 years before menopause, approximately 90% of women note mild to extreme variability in frequency and quality of menstrual flow. Menopause is defined as the cessation of menstrual flow for 1 year.
