Which statement about the Tanner Stages of Puberty is true?

• A. It is a classification system that describes the physical development of children during puberty
• B. It measures blood flow
• C. It assesses fertility
• D. It monitors hormonal levels in hair

Answer: (A)

Tanner stages are a five-stage framework used to describe puberty based on observable physical changes. It classifies how far along a person is in puberty by looking at outward maturation, such as breast development and pubic hair in girls, and testicular growth, penis development, and pubic hair in boys. It is a practical tool for tracking pubertal progression and identifying delays or unusually early or late development relative to age. It does not measure blood flow, assess fertility, or monitor hormonal levels in hair—hormones drive puberty, but the Tanner stages focus on visible changes. That’s why the statement describing Tanner stages as a classification system describing the physical development of children during puberty is true.
