Kisspeptin is a hormone that talks to a specific receptor and helps control reproductive processes like egg and sperm development, may play a role in kidney health, and can slow the spread of certain urogenital cancers, but the study doesn’t give any direct ways to use it for health or performance improvements.

Kisspeptin is a peptide hormone, which signals via the G-protein-coupled kisspeptin receptor (KISS1R). Kisspeptin-KISS1R signalling has been implicated in various physiological and pathophysiological processes in the urogenital system, including critical roles in ovarian function as a key player in the regulation of oocyte development. Kisspeptin also has roles in several different functions of the male reproductive tract, such as spermatogenesis and sperm capacitation, and is also thought to be involved in kidney physiology - studies in preclinical animal models have reported that expression of kisspeptin and/or KISS1R is altered in chronically impaired kidneys. The wider importance of kisspeptin action in the urogenital tract has been highlighted by the finding that it suppresses metastasis of urogenital carcinomas; besides the possible therapeutic potential of this finding, tissue and tumour-stage-specific alterations in kisspeptin and KISS1/KISS1R expression could potentially be used as biomarkers for the diagnosis and prognosis of urogenital carcinomas.
