Tanner Stages

Tanner Stages, also known as the Tanner Scale, describe the physical development and maturation of children and adolescents through puberty. Developed by pediatrician James Tanner, it outlines five stages based on observable changes, such as breast development in girls, testicular enlargement in boys, and the growth of pubic hair in both sexes. Each stage indicates the progression of sexual maturity and is typically used by healthcare professionals to assess growth and development during adolescence. Understanding these stages helps in recognizing normal developmental patterns and identifying potential health concerns during this critical period.
