Oxytocin
Oxytocin is a hormone produced in the paraventricular nucleus and supraoptic nucleus of the hypothalamus and released into the blood via the posterior lobe of the pituitary gland. It initiates contractions during childbirth and supports the milk ejection reflex during breastfeeding. It is also released during orgasm. Oxytocin can promote trust and strengthen pair bonding, but recent findings show that its effects are more complex and, in certain contexts, can also promote separation from out-groups.
