Gonadorelin
Gonadorelin (GnRH)
A synthetic form of gonadotropin-releasing hormone (GnRH). Used clinically for fertility treatment and increasingly in TRT protocols to maintain testicular function and fertility.
Mechanism of Action
Gonadorelin binds to GnRH receptors in the pituitary gland, stimulating the release of LH and FSH. Pulsatile administration maintains the hypothalamic-pituitary-gonadal axis, preserving testicular size and function during TRT.
Health Claims & Evidence
Maintains testicular function during TRT
Supports fertility in men on TRT
Stimulates natural testosterone production
Short-Term Effects
LH and FSH pulse within hours, maintained testicular volume and function.
Long-Term Effects
Preservation of fertility and testicular function during long-term TRT.
Side Effects
Generally well-tolerated. Mild injection site reactions. Receptor desensitization with continuous use.
Contraindications
Continuous (non-pulsatile) use causes receptor downregulation and is counterproductive.
