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.
Causes. To understand what causes precocious puberty in some children, it's helpful to know what causes puberty to begin. This process involves the following steps: 1  The brain starts the process. 2  Part of the brain makes a hormone called gonadotropin-releasing hormone (Gn-RH).strogen or testosterone in your child's body causes this type of precocious puberty. The less common peripheral precocious puberty occurs without the involvement of the hormone in your brain (Gn-RH) that normally triggers the start of puberty.
