What is kisspeptin?
Kisspeptin is a neuropeptide identified as a critical central regulator of reproduction. It binds its receptor (KISS1R) to promote release of gonadotropin-releasing hormone (GnRH), thereby driving the hypothalamic-pituitary-gonadal (HPG) axis (Xie et al., 2022).
What the research examined
Research describes specialized hypothalamic “KNDy” neurons (co-expressing kisspeptin, neurokinin B, and dynorphin) that mediate estrogen feedback on GnRH secretion. Kisspeptin is implicated in the onset of puberty and in female follicle development, oocyte maturation, and ovulation, as well as in male reproductive physiology. Disruptions of the kisspeptin/KISS1R system are linked to conditions such as idiopathic hypogonadotropic hypogonadism and central precocious puberty (Xie et al., 2022).
How it is thought to work
Kisspeptin sits upstream of GnRH, making it a key signaling node for understanding how the brain controls reproductive hormones — a major focus of neuroendocrine research (Xie et al., 2022).
The limits of the current evidence
- This is an area of active research; clinical applications are still being defined.
- Kisspeptin is not an approved medicine; this material is supplied for laboratory research use only.
