About this study
Investigating the effect of oxytocin on pancreatic endocrine functions by determining insulin and glucagon secretion within physiological ranges of plasma glucose.
Read the detailed description
Insulinotropic effects of oxytocin will be examined in 20 healthy men with body mass index (BMI) < 27 kg/m2, during a graded glucose infusion test with concomitant intravenous infusion of synthetic oxytocin or placebo in a randomized, double-blinded design. This will determine the effect of oxytocin on glucose-stimulated insulin and glucagon secretion. Additional changes in plasma/serum concentrations of C-peptide, glucose, glucose-dependent insulinotropic polypeptid (GIP), glucagon-like peptide 1 (GLP-1), and lipids will be assessed.
