WebbMechanism of Action. Gonadotropin-releasing hormone (GnRH) agonists, which were first applied in the 1980s, are currently the most widely used ADT drugs; they primarily activate GnRH receptors of the hypothalamic-pituitary-gonadal axis and produce excessive and constant stimulation, overcoming pulsatile GnRH control, which leads to downregulation … WebbGnIH acts on the pituitary and on gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus via GPR147, a G protein-coupled receptor. GnIH decreases gonadotropin synthesis and release, inhibiting gonadal development and maintenance. Such a downregulation of the hypothalamo-pituitary–gonadal (HPG) axis may be conserved …
