Mechanism of ActionKisspeptin binds to the KISS1R receptor in the hypothalamus, triggering GnRH release. This initiates the hormonal cascade leading to LH and FSH release, which regulate testosterone and estrogen production. It's the master regulator of reproductive hormones.Gonadorelin stimulates the pituitary to release LH and FSH. Pulsatile administration supports natural hormone production, while continuous administration causes desensitization and hormone suppression. Effects depend entirely on dosing pattern.
