Tanner Staging

Standardized system for assessing pubertal development used in pediatric hormone evaluation.

Full Definition

Tanner staging, also known as Sexual Maturity Rating (SMR), provides a standardized method for assessing pubertal development by evaluating secondary sexual characteristics. The system uses a 5-point scale to assess breast development and pubic hair in females, and genital development and pubic hair in males. Tanner staging is essential in pediatric endocrinology for correlating physical development with hormonal changes, timing hormone testing appropriately, and identifying precocious or delayed puberty. Clinical editors should note that Tanner staging requires clinical examination and should be documented with specific stage numbers and anatomical areas assessed.

Usage

Usage note: Always specify both breast/genital and pubic hair stages separately.
