The decapeptide fragment of kisspeptin, the master upstream regulator of reproductive endocrinology. Signalling at KISS1R on hypothalamic GnRH neurons triggers GnRH release, and thereby LH and FSH. Loss-of-function mutations in KISS1R cause hypogonadotropic hypogonadism — which is how the pathway's necessity was established. It sits above the entire HPG axis.
A genuine and active academic research subject, principally at Imperial College London. Human studies have examined its role in reproductive physiology, hypothalamic amenorrhoea, IVF trigger protocols, and sexual-response neuroimaging. Human data exist, but as physiological investigation — not as an approved therapeutic.
Not FDA-approved. Investigational; used in academic research under appropriate oversight.
Short-term administration in supervised research settings has been well tolerated. Consequences of unsupervised or repeated administration on HPG axis regulation are not established — this is a master regulator, and perturbing it casually is not a small intervention.
