Congenital HH can have a genetic origin. GnRH is synthesized as a precursor hormone that contains 92 amino acids and is then cleaved to a prohormone with a length of 69 amino acids. Multiple developmental and neuroendocrine signaling pathways regulate the ontogeny and homeostasis of the GnRH neurons including the production, secretion, and action of GnRH [ 4 ]. However, some of these releasing gonadotropin hormone characteristics make direct laboratory tests impossible, as GnRH is confined within the pituitary portal system and exhibits a short half-life of 2 to 4 minutes.
