oxytocin

Oxytocin is a 9-amino acid peptide hormone and neuropeptide produced in the hypothalamus and released by the posterior pituitary, crucial for childbirth, lactation, and social bonding, earning it nicknames like the "love hormone" for fostering trust and attachment. While known for maternal/bonding roles, its effects are complex, influencing social cues, potentially increasing pro-social behavior in women but sometimes promoting avoidance or negative judgment in men, and affecting stress response and metabolism.
