Summary

This study tested whether people with hypopituitarism (a condition where the pituitary gland doesn't work properly) have lower oxytocin levels compared to healthy individuals. Researchers gave participants a drug called exenatide (a GLP1 receptor agonist) to see if it could stimulate oxytocin release. The goal was to better understand oxytocin deficiency in these patients, not to treat it.
