Oxytocin – The Fidelity Hormone?

Scientists have announced the lastest finding into the remarkable roles that oxytocin plays in love and social relationships. Already known as the love hormone on account of studies demonstrating its significance for bonding between mothers and children, sexual partners, and people in general, the latest research suggests that oxytocin might also be a factor in the degree that husbands stay faithful to their wives.

A nasal spray containing the hormone caused men with wives or long-term partners to keep a greater distance from attractive women but had no affect on bachelors, researchers found.

Although those in relationships did not judge the woman to be any less attractive, they began to feel uncomfortable more quickly when approached by the woman and asked her to remain further away.

Oxytocin, dubbed the “love hormone”, was already known for its role in attraction and bonding in both men and women, but had never been shown to play a lasting role in long-term relationships.

The findings suggest that boosting levels of oxytocin could help maintain marriages by preventing men from appearing interested in other women, researchers said.


Oxytocin is already used as a complimentary therapy by some marriage counsellers in the USA.
