Two years is all you get for a passionate romance before your hormones fail you, says a new study.
The study, which showed that different hormones are present in blood in various stages of love, found romantic passion fades after two years.
Researchers in Italy used blood tests to establish the levels of a variety of hormones in volunteers - some were just starting out with a new partner while others had been in an established relationship for years.
They found that a nerve growth factor called neurotrophins exceeded normal levels in those enjoying the love-struck early stages of romance. But it was missing from the volunteers who had been settled with their partners for up to two years, reported the online edition of Daily Mail.
Scientists from the University of Pisa found it had been replaced by oxytocin, which they nicknamed "the cuddle hormone", in those who had been together for several years.
Oxytocin is a chemical known to induce labour and milk-production in pregnant and new mothers.
