Pubertatea este perioada vieții dintre copilărie și maturitate când organismul uman, atât feminin, cât și masculin, se dezvoltă din punct de vedere psihic, cât și fizic, în special organele sexuale, devenind adult și capabil pentru a se reproduce sexual. Pubertatea declanșată de stimulii hormonali din creier trimiși către gonade, ovarele la fete și testiculele la băieți. Ca răspuns la acești stimuli gonadele produc hormoni care stimulează libidoul și creșterea, funcționarea și transformarea creierului, oaselor, mușchilor, sângelui, sânilor și organelor sexuale. Pubertatea începe în general în jurul vârstei de 10 - 12 ani^[1]. La fete aceasta debutează în jurul vârstei de 10 - 11 ani și se încheie în jurul vârstei de 15 - 17 ani, iar la băieți debutează la 11 - 12 ani și se încheie în jurul vârstei de 16 - 17 ani. Punctul de început al pubertății la fete este menarha, stadiul de început al menstruației, ce are loc prima dată în jurul vârstei de 12 - 13 ani. La băieți punctul de început al pubertății este prima ejaculare, spermarha, ce apare prima dată în jurul vârstei de 12 - 13 ani.

The sequence and age range of the developmental changes associated with puberty can vary widely. Although most children begin puberty between the ages of 10 and 12, it can start at any age from 8 to 16. The most obvious determining factor is gender; on average, puberty arrives earlier for girls than boys. Heredity also appears to play an important role. Compared to an overall age range of nine to 18 for menarche, the age difference for sisters averages only 13 months and for identical twins, less than three months. Body weight is a factor as well: puberty often begins earlier in heavier children of both sexes and later in thinner ones. The onset of menstruation, in particular, appears to be related to amounts of body fat. Girls with little body fat, especially athletes, often start menstruating at a later than-average age. Over the past 100 years, puberty has tended to begin increasingly early in both sexes (a phenomenon called the secular trend).

The timing of physical maturation varies widely. In the United States today, menarche, the first menstrual period, typically occurs around age 12, although some youngsters start puberty when they are only eight or nine, others when they are well into their teens. The duration of puberty also varies greatly: eighteen months to six years in girls and two to five years in boys.
