Research Overview
Secretin
Secretin is a classic GI hormone with extensive physiology literature and established diagnostic use. It remains important for studying pancreatic secretory function, biliary responses, and duodenal feedback.
Kisspeptin-52
Human and animal studies show kisspeptin-52 can acutely increase gonadotropin secretion and activate the hypothalamic-pituitary-gonadal axis. It has been explored in fertility research and assisted-reproduction settings as a way to trigger endogenous reproductive hormone release.
