Kisspeptin

Kisspeptin-54. GnRH-stimulating peptide. 54-amino acid neuropeptide that acts as a master regulator of GnRH/LH/FSH axis. Studied for testosterone optimization and fertility.

Intelligence Profile

Clinical Applications

Kisspeptin is being investigated across several reproductive and endocrine applications, though much of the clinical evidence remains in early-stage research.

Reproductive Disorders and Infertility

Clinical studies are examining kisspeptin's role in female infertility, with completed trials measuring serum kisspeptin levels in infertile women (NCT03018314) and investigating its expression in human reproductive cells (NCT02877992). Research is also exploring kisspeptin levels throughout pregnancy in women with polycystic ovary syndrome (PCOS), a common cause of infertility (NCT06545994).

Pubertal Development Assessment

A Phase 3 clinical trial has investigated the relationship between kisspeptin signaling sensitivity and pubertal onset in boys (NCT03286517). Recent research has examined serum kisspeptin profiles during hormonal stimulation tests in children with central precocious puberty and premature thelarche, suggesting potential diagnostic applications in evaluating abnormal pubertal timing.

GnRH System Evaluation

An ongoing Phase 1 trial is using kisspeptin to assess GnRH (gonadotropin-releasing hormone) neuronal function in both healthy individuals and those with disease (NCT07224490). This approach leverages kisspeptin's role as a key regulator of the reproductive hormone axis.

Emerging Applications

Preliminary research suggests kisspeptin may have broader therapeutic potential beyond reproductive health. Laboratory studies indicate kisspeptin-54 might help treat acute lung injury in sepsis through anti-inflammatory mechanisms, though this remains in preclinical stages.

Current Limitations

The clinical evidence for kisspeptin remains largely investigational. Most completed trials appear to be observational studies measuring kisspeptin levels rather than therapeutic intervention trials. The therapeutic applications are still being defined, and more robust clinical trial data is needed to establish efficacy and safety for specific indications.
