Puberty is the physiological sequence of events when secondary sexual characteristics develop, reproductive capacity is achieved, and final adult stature reached. The outward signs usually develop over 3 to 5 years, with significant variation both in the age that puberty starts and the pace at which development proceeds. The events that lead to the triggering of puberty remain uncertain, but clinical presentations may arise because the process is abnormally early (precocious puberty) or abnormally late (delayed or absent puberty). Several variants of the normal processes may also present for clinical assessment, for example, premature isolated thelarche (breast development) or adrenarche (pubic and axillary hair development), which do not require treatment.
