Tanner staging
A standardized assessment system used to evaluate the progression of physical development during puberty.
Full Definition
Tanner staging is a clinical assessment tool that categorizes physical development during puberty into five stages (Tanner I-V) based on secondary sexual characteristics. Developed by James Tanner, this system evaluates breast development and pubic hair growth in females, and genital development and pubic hair growth in males. Healthcare providers use Tanner staging to determine if adolescent development is proceeding normally and to identify potential developmental delays or precocious puberty. The staging is crucial for clinical decision-making regarding hormone therapy, psychological support, and timing of medical interventions.
Usage
Usage note: Always capitalize 'Tanner' as it is named after James Tanner. Use Roman numerals (I-V) for staging.
