From the Guidelines
Tanner's classification, also known as Tanner staging, is a system used to assess the physical development of children and adolescents during puberty, consisting of five stages (Tanner stages 1-5) that describe the development of secondary sexual characteristics.
Overview of Tanner Staging
The classification evaluates different aspects of development in males and females. For males, it assesses genital development and pubic hair growth, while for females, it evaluates breast development and pubic hair growth.
- Tanner stage 1 represents the prepubertal state with no visible secondary sexual characteristics.
- Stages 2-4 represent progressive development during puberty.
- Stage 5 indicates adult development. This classification is crucial in clinical practice for determining whether a child's pubertal development is occurring at an appropriate age and progressing normally, helping to identify conditions such as precocious puberty (early onset) or delayed puberty 1.
Clinical Application
Healthcare providers use Tanner staging during physical examinations to monitor normal development and detect potential endocrine or growth disorders. Understanding where a child falls on the Tanner scale provides context for growth patterns, psychological development, and the timing of certain health interventions. For instance, Tanner stage 2 breast development before 8 years of age is considered a reasonable definition of precocious puberty in girls 1.
Importance in Various Contexts
The application of Tanner staging is not limited to general pediatrics; it is also significant in the management of survivors of childhood, adolescent, and young adult cancers, where monitoring of growth and pubertal development is recommended for at-risk pre- and peripubertal survivors 1. This monitoring helps in the early detection of potential issues related to puberty and fertility in these patients.

From the Research
Definition of Tanner's Classification
Tanner's classification, also known as Tanner staging, is a scale used to assess pubertal development in children and adolescents. It evaluates the physical development of secondary sexual characteristics, such as breast development, genital development, and pubic hair growth.
Components of Tanner's Classification
The Tanner scale assesses the following components:
- Breast development (in females)
- Genital development (in males)
- Pubic hair growth
- Axillary hair growth
Stages of Tanner's Classification
The Tanner scale consists of five stages, ranging from Stage 1 (prepubertal) to Stage 5 (adult):
- Stage 1: Prepubertal
- Stage 2: Initial development of secondary sexual characteristics
- Stage 3: Further development of secondary sexual characteristics
- Stage 4: Advanced development of secondary sexual characteristics
- Stage 5: Adult development of secondary sexual characteristics
Clinical Application of Tanner's Classification
Tanner staging is used in clinical practice to:
- Assess normal pubertal development
- Identify precocious puberty (early onset of puberty)
- Identify delayed puberty (late onset of puberty)
- Monitor treatment of pubertal disorders As noted in the study 2, Tanner staging allows for an objective measurement of pubertal status and can help identify underlying pathology.
Key Points
- Tanner's classification is a widely used scale to assess pubertal development in children and adolescents.
- The scale evaluates breast development, genital development, pubic hair growth, and axillary hair growth.
- The five stages of the Tanner scale range from prepubertal to adult development.
- Tanner staging is used in clinical practice to assess normal pubertal development, identify precocious or delayed puberty, and monitor treatment of pubertal disorders, as discussed in studies 3, 4, 5, 6.
