Kisspeptin is a neuropeptide encoded by the KISS1 gene and plays a central role in regulating the reproductive axis. It can effectively stimulate the secretion of gonadotropin-releasing hormone (GnRH), thereby controlling the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland.

In scientific research, kisspeptin has attracted considerable attention for its importance in puberty, fertility, reproductive function, and potential therapeutic applications for hormonal disorders. Its ability to modulate the hypothalamic-pituitary-gonadal axis renders it significant in studies of reproductive endocrinology and energy metabolism.
