Research has discovered a role for prolactin, the hormone that stimulates milk production in nursing mothers, in the bond between parents. The study on cotton-top tamarins found a link between prolactin levels and sexual activity and cuddling among paired adults. Although this was a first for prolactin, it has previously been found for oxytocin, a hormone that stimulates childbirth and is linked to a range of pleasurable emotions.
