Puberty: The Transformation of Darren and Natalie

Introduction

• Story of Darren Bruff and Natalie Jackson
• Context: Their bodies are preparing for reproduction

Female Development

Natalie

• Ovaries contain immature eggs in suspended animation

• Testicles contain cells destined to produce sperm but are dormant pre-puberty
• Hormonal signals, especially at night, activate testicular changes
• Testosterone: Key hormone driving changes
• Effects on body: Muscle growth, increased sensitivity in genitals, emergence of sex drive
• Emotional changes influenced by testosterone
• Sperm production begins, but full reproductive maturity is years away

Differences Between Genders

• Boys require conversion of testosterone to estrogen for growth spurt
• Differences in the onset of secondary sexual characteristics
• Psychological and emotional changes differ due to hormonal influences

Common Challenges
