Kisspeptin-10 is a peptide hormone derived from the KiSS-1 gene and functions as a natural ligand for the G protein-coupled receptor GPR54. Researchers primarily study kisspeptin-10 for its significant role in regulating reproductive hormones, including luteinizing hormone and follicle-stimulating hormone, which are crucial for fertility. Key findings indicate that kisspeptin-10 can stimulate testosterone production and has been linked to the onset of puberty, while also playing a role in the regulation of ovarian functions and bone metabolism. Current research is focused on understanding its metabolic pathways and potential implications in both reproductive health and conditions such as osteoporosis, as well as its inclusion in anti-doping regulations due to its performance-enhancing effects in sports.
