GNRH1 and precocious puberty: Gonadotropin-dependent and gonadotropin-independent precocious puberty can be distinguished by differences in the responses to GnRH-stimulation testing, as GnRH-stimulated luteinising hormone (LH) and follicle stimulating hormone (FSH) concentrations are suppressed in pseudoprecocious puberty, but increased in central precocious puberty [8].
