What is Early Puberty?
Early puberty is when your son starts showing the first signs of puberty before he is 9 years old. This can be normal, but might require evaluation by a pediatric endocrinologist (hormone doctor).
What is Normal Puberty?
Normal puberty is when children’s bodies start to grow and develop into young adult bodies. Boys usually start to go through puberty between the ages of 9-14 years. When your son starts to go through puberty, his gonads (testes) and adrenal glands (glands that sit on top of the kidneys) release hormones. These hormones cause the first signs of puberty, which are an increase in the size of the testes and length of the penis, body odor, underarm hair, pubic hair and acne (pimples). Over time, boys will develop later signs of puberty, such as increased muscle mass, stronger bones, voice deepening and a growth spurt.
There are 2 types of puberty that make up the entire pubertal process. These are:
- Adrenal puberty
This is when the adrenal glands make hormones that cause the first signs of puberty; body odor, underarm hair, pubic hair and acne (pimples).
- Gonadal puberty
This is when the pituitary gland (a small gland in the brain that controls other glands in the body) makes hormones (FSH and LH) that tell the testes to increase in size and make testosterone.
