Puberty Related Disorders

Delayed Puberty
Early Puberty

Precocious puberty is when a child's body begins changing into that of an adult (puberty) too soon. When puberty begins before age 8 in girls and before age 9 in boys, it is considered precocious puberty.
Puberty includes rapid growth of bones and muscles, changes in body shape and size, and development of the body's ability to reproduce.
The cause of precocious puberty often can't be found. Rarely, certain conditions, such as infections, hormone disorders, tumors, brain abnormalities or injuries, may cause precocious puberty. Treatment for precocious puberty typically includes medication to delay further development.

Symptoms

Precocious puberty signs and symptoms include development of the following before age 8 in girls and before age 9 in boys.

• Breast growth and first period in girls
• Enlarged testicles and penis, facial hair and deepening voice in boys
• Pubic or underarm hair
• Rapid growth
• Acne
• Adult body odor

Central precocious puberty

In central precocious puberty, the puberty process starts too soon. The pattern and timing of the steps in the process are otherwise normal. For the majority of children with this condition, there's no underlying medical problem and no identifiable reason for the early puberty.

Peripheral precocious puberty

Estrogen or testosterone in your child's body causes this type of precocious puberty.
The less common peripheral precocious puberty occurs without the involvement of the hormone in your brain (GnRH) that normally triggers the start of puberty. Instead, the cause is release of estrogen or testosterone into the body because of problems with the ovaries, testicles, adrenal glands or pituitary gland.

Complications

• Short height. Children with precocious puberty may grow quickly at first and be tall, compared with their peers. But, because their bones mature more quickly than normal, they often stop growing earlier than usual. This can cause them to be shorter than average as adults. Early treatment of precocious puberty, especially when it occurs in very young children, can help them grow taller than they would without treatment.
• Social and emotional problems. Girls and boys who begin puberty long before their peers may be extremely self-conscious about the changes occurring in their bodies. This may affect self-esteem and increase the risk of depression or substance abuse.

Delayed Puberty

Puberty that happens late is called delayed puberty. This means a child's physical signs of sexual maturity don’t appear by age 12 in girls or age 14 in boys. This includes breast or testicle growth, pubic hair, and voice changes. These are known as secondary sexual characteristics.
