Targets / mechanism

• oxytocin receptor agonism
• uterotonic effect
• social cognition pathway hypotheses

Optimization domains

• labor
• lactation
• social cognition
• autism
• bonding
• CNS
• endocrine

Research basis

• Approved injectable oxytocin has clear obstetric label context, and intranasal human literature gives a real but mixed social-cognition research base.

Limits, risks, and missing evidence

• Obstetric oxytocin and intranasal social-cognition research are different routes, endpoints, and risk contexts.
• Hyponatremia/water intoxication, uterine hyperstimulation, cardiovascular effects, psychiatric-context variability, and lack of durable social-benefit evidence matter.

Risk flags

• prescription
• uterotonic
• hyponatremia
• blood pressure
• psychiatric context
• route extrapolation
• medical supervision
