Gonadorelin
A GnRH peptide that signals the pituitary to release LH and FSH, driving endogenous testosterone and gonadal function.
Medically reviewed by Dr. Jonathan Snipes, MD. Last reviewed May 6, 2026.
What It Is
Gonadorelin is synthetic GnRH (gonadotropin-releasing hormone). On testosterone therapy it is used to maintain testicular function and fertility that exogenous testosterone otherwise suppresses, a role historically filled by hCG.
How It Works
It acts on the pituitary to release LH and FSH, which drive testicular or ovarian function and your own testosterone. The critical principle is pulsatility: GnRH naturally pulses, so intermittent dosing stimulates the axis while continuous exposure downregulates it. Frequency is set carefully for that reason.
Who It's For
Men on TRT who want to preserve testicular size and fertility markers, and patients on physician-directed fertility protocols. Requires hormone monitoring.
Who Should Avoid It
Avoid in pregnancy. Discuss any hormone-sensitive condition or pituitary disorder with your prescriber before starting. Coordinate with any testosterone, hCG, estrogen, or fertility treatment, and monitor LH, FSH, and testosterone or estradiol. Prohibited in tested sport under the WADA Prohibited List.
