A synthetic decapeptide identical to endogenous gonadotropin-releasing hormone (GnRH), stimulating pituitary gonadotrophs to release both LH and FSH. Unlike GnRH agonist analogs (leuprolide, nafarelin) that cause initial stimulation followed by receptor downregulation, gonadorelin at physiological pulse frequencies maintains normal HPG axis function. Used clinically for GnRH stimulation testing and to maintain gonadal function during exogenous hormone administration.
Key distinction: Bioidentical to endogenous GnRH — pulsatile administration maintains natural HPG axis function without the receptor downregulation caused by long-acting GnRH agonist analogs.
