Quizplus · Accepted Answer

Oxytocin is released during breastfeeding and is responsible for the letdown of milk. It is also released during skin-to-skin contact and promotes bonding between individuals. It is a mammalian hormone that also acts as a neurotransmitter in the brain, regulating social interaction and sexual reproduction. Adrenaline and vasopressin are not typically associated with breastfeeding or contact and warmth. Estrogen does play a role in lactation, but it is not primarily associated with the release of milk during breastfeeding.
