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.
For girls, puberty begins when the specialized hormones tell the ovaries to begin producing another hormone, known as estrogen. Estrogen is responsible for most of the changes in a girlâs body during puberty. It causes her body to mature and prepare for pregnancy. In males, the follicle-stimulating hormone and the luteinizing hormone act on the testicles. The testicles, or testes, are two egg-shaped glands that produce sperm and male hormones.
