Kisspeptin

The KISS1 gene encodes Kisspeptin, a vital neuropeptide. It serves as a key upstream regulator of the hypothalamic-pituitary-gonadal (HPG) axis.

Research on Kiss peptin has advanced our understanding of reproductive endocrinology. It controls gonadotropin-releasing hormone (GnRH) secretion. In turn, GnRH governs pituitary release of luteinising hormone (LH) and follicle-stimulating hormone (FSH).

Kiss peptin acts as the primary gatekeeper of puberty onset. It also mediates sex steroid feedback loops that regulate cyclical reproduction.

Scientists study its applications in hypogonadotropic hypogonadism, hypothalamic amenorrhoea, and infertility. In multiple studies, administering Kiss peptin robustly stimulated LH pulses in both male and female subjects.

Kisspeptin neurons in the arcuate and anteroventral periventricular nuclei coordinate these fertility signals. As the primary activator of this hormonal cascade, Kiss peptin remains essential to reproductive biology research.
