What is it?

Precocious sexual development and puberty is when the child's body begins to change and have adult characteristics too early. Precocious puberty refers to the beginning of puberty before the age 9 in boys and 8 in girls. Puberty consists of several stages of changes such as the development of breast buds and pubic hair, enlargement of the penis and scrotum in boys, ance, armpit hair, height increase and having the first period.
When these changes occur too early, it is usually constitutional- meaning that no adequate cause has yet been found. Central precocious puberty refers to a situation in which the brain releases the puberty hormones too early in life. Usually, the reason cant be found but sometimes it may be caused due to tumors, radiation, injury, hypothyroidism, or genetic syndromes. Peripheral precocious puberty is less common and happens due to excessive release of estrogen or testosterone due to tumors, cysts, exposure to external sources of these hormones or genetic syndromes.
