Kisspeptin-10

Kisspeptin-10 (KP-10)

Evidence & Status

  • Moderate Evidence
  • Moderate

At a Glance

A naturally occurring hypothalamic peptide that acts as a master upstream regulator of the reproductive hormone axis, triggering GnRH release and initiating the cascade that drives LH, FSH, and sex hormone production. Studied in reproductive medicine and the biology of puberty onset.

Plain English

Researchers study Kisspeptin-10 because it appears to be one of the key signals that activates the body's entire reproductive hormone system. Scientists are interested in how kisspeptin regulates the timing and pulsatility of GnRH release — the hormone that starts the cascade controlling testosterone, estrogen, and reproductive function. It is of particular interest in research on conditions where the reproductive hormone axis is suppressed or disrupted, such as hypothalamic amenorrhea, and also in studies exploring how puberty is triggered and regulated at the molecular level.
