Oxytocin, often called “the love drug,” is a hormone produced in the hypothalamus and released into the bloodstream by the pituitary gland. In the brain, it functions as a chemical messenger, playing a crucial role in various human behaviors such as recognition, trust, emotional bonding, and romantic attachment. Both men and women release oxytocin during intercourse, which supports the idea that it is involved in sexual bonding. Additionally, oxytocin has a stress-buffering effect that inhibits stress-induced HPA activity and reduces cortisol levels.
