Disorders of Pubertal Onset

Abstract

Evaluation of the child with abnormal pubertal development can be challenging for the primary care provider. Understanding the factors associated with timing of pubertal onset and the normal sequence of pubertal changes is useful in evaluation of children with puberty disorders. A thorough workup includes assessment of growth rate, Tanner staging, and rate of pubertal progression, in addition to an extensive history and physical examination to identify signs and symptoms of disorders associated with abnormal pubertal timing. Initial diagnostic studies will most often include a bone age, levels of gonadotropins, and levels of estradiol (for girls) or testosterone (for boys).
