What Is Puberty?Puberty is the time when a child’s body starts to grow and change into an adult body. For boys, it usually starts between ages 9 and 14. These changes are normal and natural, and they happen slowly over a few years.Here are 5 Physical and Emotional Changes Boys Experience During Puberty:1. Voice Becomes Deeper • The voice box (or Adam’s apple) gets bigger. • At first, your voice may “crack” or sound funny, but later it becomes deeper and more adult-like.2. Body Hair Starts to Grow • Hair begins to grow in new places like the underarms, legs, and face (you may start to see a mustache!). • This is a sign that your body is becoming more mature.3. Growth Spurt • Boys often grow taller quickly during puberty. • Your hands, feet, and muscles may also grow fast, and you may feel clumsy at times.4. Changes in the Private Parts • The testicles and penis get larger during puberty. • This is part of your body’s way of preparing for adulthood.5. Mood Swings and New Emotions • You might feel happy one moment and upset the next, or feel more sensitive or easily annoyed. • This happens because of changes in hormones—special chemicals that affect your body and emotions.Why These Changes MatterThese changes mean that your body is growing up, and that’s something everyone goes through and even adults were once your age and went through puberty too.
