Precocious Puberty

Abstract

Precocious puberty is a common presentation to pediatricians with a significant overlap between physiology and pathology. While most girls with precocious puberty have no identifiable cause, boys are more likely to have a pathological cause. The trend of earlier onset of thelarche with slow pubertal tempo has led to a significant increase in the number of girls presenting with precocious puberty. Advanced growth, bone age, uterine maturation, and elevated LH suggest rapidly progressive puberty. The critical issues in evaluating a child presenting with precocious puberty include its confirmation, exclusion of physiological variants, identification of the cause, and determining the need for treatment. Step-wise evaluation with emphasis on clinical parameters provides cost-effective assessment. Gonadotropin-releasing hormone (GnRH) analogs remain the mainstay of treatment for central precocious puberty but should be restricted to individuals with rapidly progressive puberty and compromised final height. The management of rarer forms of peripheral precocious puberty (McCune Albright syndrome, congenital adrenal hyperplasia, and testotoxicosis) involves using experimental drugs under the guidance of specialists.
