Written there, Nerve Growth Factor or NGF triggers the powerful emotions seen in new lovers. This is according to a research done by Pavia University researchers. According to the research, those who have recently fallen madly in love have far higher levels of NGF compared to single people or those in long term relationships. However, after a year with the same lover, the quantity of the ‘love molecule’ in their blood had fallen to the same level as that of the other groups.Also written in MMR, regarding the possibility of the new blood test in the future, to check for serum NGF level to rate LOVE. :)
Written there as well, the researchers were not clear how falling in love triggers higher levels of NGF, but the NGF clearly has an important role in the "social chemistry" between couples at the start of a relationship.
