Oxytocin is a hormone and neuropeptide produced in the hypothalamus and released by the posterior pituitary gland, best known for its crucial roles in childbirth, breastfeeding, and social bonding. It stimulates uterine contractions during labor, aids milk ejection during lactation, and influences emotions such as trust and attachment. The history of oxytocin dates back to 1906, when Sir Henry Dale first identified its ability to contract uterine muscles. Its scientific significance grew further in 1953 when Vincent du Vigneaud determined its structure and became the first to successfully synthesize a peptide hormone, earning a Nobel Prize. Since then, oxytocin has remained important in medicine and research on human behavior.
