Oxytocin

Oxytocin exerts its effects by binding to oxytocin receptors, which are G-protein coupled receptors found in various tissues. This interaction triggers intracellular signaling cascades that influence both the central nervous system and peripheral organ systems.

A. Cardiovascular Protection

• May reduce heart attack size and improve heart function under stress

• Lowers the risk of arrhythmias and supports parasympathetic (calming) activity

• Helps regulate blood vessel elasticity, promotes vasodilation, and reduces inflammation

• Mitigates stress-related cardiovascular strain by lowering blood pressure and heart rate variability

B. Metabolic Health

• Long-acting oxytocin analogs show potential in weight loss and blood sugar regulation

• Improves lipid profiles and enhances insulin secretion

• Promotes gene expression related to lipolysis and gluconeogenesis

C. Sexual and Reproductive Function

• Influences sexual behavior and ejaculatory reflexes in males

• Affects testicular function and sperm motility

• Plays a role in pair-bonding, empathy, and social connection, which may enhance sexual response

• Investigated as a potential treatment for sexual dysfunction in both men and women via intranasal spray
