Both genetic and environmental factors are involved in the timing of puberty. Body fat and/or body composition may play a role in regulating the onset of puberty. Puberty is associated with the development of secondary sex characteristics and rapid growth. Central precocious puberty (CPP) is puberty that occurs earlier than normal due to release of hormones from the hypothalamus of the brain.
The increase in growth rate that occurs during puberty is driven by the body's increase in production of sex hormones: estrogen from the ovaries in girls, and testosterone from the testicles in boys. These hormones cause the skeleton to grow and to mature more rapidly.rowth is controlled by hormones (chemical messengers) from various glands. One of the most important, growth hormone, is secreted by the pituitary gland. The gland looks like a peanut sitting at the base of the brain. Other hormones also are essential for growth.
