what is oxytocin

Oxytocin is a hormone and neuropeptide made in the hypothalamus and released from the pituitary gland that plays a key role in childbirth, breastfeeding, and social bonding. People sometimes call it the “love hormone” or “bonding hormone” because of its effects on attachment and social behavior.

Quick Scoop: What Is Oxytocin?

• A small peptide made of nine amino acids that acts as both a hormone and a neurotransmitter in the brain.

• Produced in the hypothalamus and released into the blood by the posterior pituitary.

• Best known for its roles in:
  • Uterine contractions during labor.

* Milk let‑down (ejection) during breastfeeding.

* Maternal behavior and nurturing, as well as other social and bonding behaviors.

Think of oxytocin as your body’s built‑in “connection and birth” signal: it helps the uterus contract to deliver a baby, helps milk flow to feed the baby, and also supports feelings of closeness and trust with others.
