Kids go through many stages of growth during their lives. Out of all the growth milestones, puberty is one of the most crucial phases. It indicates that your kids are going through significant changes that are necessary, natural, and healthy.

What is Puberty?

Puberty is the phase in growing up that includes physical, emotional, and psychological changes. These are important signs that your kid is moving towards adulthood.

Some of the key changes that happen during puberty are:

  • Physical growth both inside and outside the body
  • Growth of sexual organs
  • Brain development
  • Emotional changes
  • Changes in social relationships

When Does Puberty Start?

Kids can hit puberty at different points from pre-teens to teen years. For boys, puberty typically starts in the range of 9 - 14 years of age. This is the time that sex hormones are being released from the gonads (which are testes for the boys). Puberty changes can be completed at any time between the range of 18 months to 5 years. 


Key Physical Changes in Puberty for Boys

There are some main physical changes that your kid will go through from the age of around 9 to 14. Here is what you should expect:

Physical Strength

  • Noticeable change in the body shape as muscle tissues start increasing
  • Your boy will become taller, and his shoulders will get broader.
  • Motor skills and hand-eye coordination will increase.


Hair growth

  • Pubic hair will start growing around the genitals.
  • Hair will also grow on the arms, chest, underarms, and face.

Skin and Hair
