Causes of central precocious puberty can include: 1  damage to the inhibitory system of the brain (due to infection, trauma, or irradiation), 2  hypothalamic hamartoma produces pulsatile gonadotropin-releasing hormone (GnRH), 3  Langerhans cell histiocytosis, or.  McCuneâAlbright syndrome.
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.
