# Kisspeptin-10 > Upstream regulator of GnRH studied for reproductive endocrinology. Source: https://peptides.cafe/peptide/kisspeptin-10 Category: Hormonal · HPG Axis Tag: Hormonal · HPG axis ## Mechanism A peptide product of the KISS1 gene that acts upstream of GnRH neurons via the KISS1R/GPR54 receptor. Research demonstrates robust LH (and indirectly testosterone/estradiol) responses without desensitizing the pituitary. ## Research areas - Hypothalamic amenorrhea - Male hypogonadism research - IVF triggering protocols ## Common research protocols - Subcutaneous research: Investigational subcutaneous or IV dosing in reproductive endocrinology studies. ## Study summaries - "Kisspeptin-10 in reproductive endocrinology" — Journal of Clinical Endocrinology & Metabolism (2014): Restored LH pulsatility in women with hypothalamic amenorrhea. ## Considerations - Investigational; not FDA-approved. - Effects on the HPG axis warrant physician oversight. ## Disclaimer Educational content only.
