Puberty and the Tanner Stages - James M. Tanner

Puberty is the natural process of physical and sexual maturation that occurs during adolescence. The Tanner stages, developed by James M. Tanner, are a system used to assess and categorize the physical changes that occur during puberty in children and adolescents. These stages provide a standardized way to track the progression of puberty.

James M. Tanner did extensive research and provided the framework for understanding puberty and the Tanner stages. However, it is not an individual who files these stages. They are widely used in the medical field to assess and monitor the physical development of adolescents.
