Delayed Puberty

Abstract

Delayed puberty is defined as the absence of physical signs of puberty 2 to 2.5 standard deviations above the mean age and affects approximately 2% of adolescents. Causes of delayed puberty are broadly divided into two categories: hypergonadotropic hypogonadism and hypogonadotropic hypogonadism. One exception to this classification system is constitutional delay of growth and puberty, the most common cause of delayed puberty. For the general pediatrician, knowledge of the different causes and initial steps to evaluation is crucial when a patient with delayed puberty presents. [Pediatr Ann. 2018;47(1):e16-e22.].
