Oxytocin

Oxytocin is a hormone produced in the hypothalamus and secreted by the pituitary gland’s posterior lobe. This chemical messenger is also referred to as the “love hormone” or “cuddle hormone” because it is being released when people become intimate with each other. It also plays a role in attachment and empathy. Interestingly, current research has pointed out its influence in fostering monogamy and faithfulness. Moreover, oxytocin is significantly associated with reproduction since it is stimulated during sex, giving birth, and lactation.
