Kisspeptin is a naturally occurring peptide hormone primarily recognized for its critical role in regulating reproductive function and hormone secretion, particularly through the activation of gonadotropin-releasing hormone (GnRH). Produced in the hypothalamus, kisspeptin stimulates the pituitary gland, leading to the release of key reproductive hormones such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which are essential for maintaining fertility, puberty initiation, menstrual cycle regulation, and testosterone production. Clinically, kisspeptin has gained significant attention for its potential therapeutic applications in treating reproductive disorders, enhancing fertility outcomes, and managing conditions characterized by hormonal imbalances, such as polycystic ovary syndrome (PCOS) and hypogonadism.
