Also known as: Pitocin, Syntocinon, Love Hormone

The bonding hormone with roles in sexual function, social behavior, and reproduction.

Overview

Oxytocin is a nonapeptide hormone produced in the hypothalamus with diverse roles in bonding, sexual behavior, childbirth, and social cognition.

Mechanism of Action

Binds oxytocin receptors in brain (social/bonding effects), uterus (contractions), and reproductive tissues. Enhances social bonding, trust, and sexual response.

Pharmacokinetics

Short half-life (3-5 minutes IV; longer intranasal). Intranasal administration achieves CNS effects.
