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.
Excess hormone stimulation is the cause for precocious puberty. It can come from the brain in the form of gonadotrophins or from the gonads and adrenals. Overproduction may be caused by functioning tumors or simple overactivity. Brain overproduction can also be the result of brain infections or injury.
