Oxytocin is called the love hormone because it is usually released when people hug, cuddle, or socially bond.
It is also called the “cuddle hormone”. However, studies have also shown that oxytocin can intensify social memories of relationships that have gone bad.
Depending on the environment, this hormone can also make an individual feel suspicious. It can also make people less accepting of outsiders.
Oxytocin is synthesized in the hypothalamus and released from the posterior pituitary or neurohypophysis.
Oxytocin stimulates the contraction of smooth muscles in the uterus at the time of childbirth.
It also stimulates the ejection of milk from mammary glands.
