Variations of tempo and progression
Tempo is the speed at which the process of pubertal changes progresses from beginning to end. The duration of puberty generally varies less than timing of onset, and approximates 4 years for girls and 6 for boys (from first physical changes to attainment of adult height). Nevertheless, some healthy children can proceed through puberty at a faster or slower tempo than most.
An interruption of progression of puberty is usually, but not always, due to abnormal causes such as
malnutrition or
anorexia nervosa. Perhaps the most common apparently healthy variation is apparent interruption for a couple of years just after attainment of an early sign of initiation. For instance, some girls may seem to develop stage 2 breast buds at 6 or 7 years of age with no other signs of puberty, and nothing may happen for 2 or 3 years. Physicians refer to this as "unsustained puberty."
Conclusion
In a general sense, the conclusion of puberty is reproductive maturity. Criteria for defining the conclusion may differ for different purposes: attainment of the ability to reproduce, achievement of maximal adult height, maximal gonadal size, or adult sex hormone levels. Maximal adult height is achieved at an average age of ~ 15 years for an average girl and ~ 18 years for a average boys. Potential fertility (sometimes termed
nubility) usually precedes completion of growth by 1-2 years in girls and 3-4 years in boys. Stage 5 in the tables above[
clarification needed] typically represents maximal gonadal growth and attainment of adult hormone levels.
