Mechanism of Action

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.

Research Summary

FDA approved for diagnostic testing of pituitary function. Used to stimulate testosterone production when given in pulses. Continuous use leads to chemical castration effect used in prostate cancer and endometriosis.
