Adolescence is a period of maturity, a point of physical, emotional, social and psychological change. It is considered to be the period between ages 10 and 19. Puberty is the process of biological, psychological and physical development through which sexual reproduction becomes possible. Progression occurs through sequential changes described as Thelarche – Adrenarche – Peak growth spurt – Menarche – Ovulation.
Menstruation is described as the exclusive sign of femininity. It is well known that the terms menstruation and menses are derived from the Latin word menses (month), which in turn relates to the Greek word ‘mene’ (moon) and to the roots of the English word month reflecting the fact that the moon also takes close to 28 days to revolve around the Earth (actually 27.32 days).
The age of menarche is determined by general health, genetic, socio-economic, nutritional factors, geographic location, exposure to light and psychological state. The mean age of menarche is typically between 12 and 13 years. The initial cycles after menarche are often irregular with a particularly greater interval between first and second cycle. The early menstrual cycles are thought to be anovulatory.
Most women bleed for 2 to 7 days during their first menses. Most normal cycles range from 21 to 45 days, despite variability even in the first gynaecologic year, although short cycles of fewer than 20 days and long cycles of more than 35 days may occur. By the third year after menarche, 60% to 80% of menstrual cycles are 21 to 34 days long, as is typical of adults.
