Animal testing is beginning to shed light on the complex neural and genetic components of love in the same way they have led to pharmaceutical therapies for anxiety, phobias and post-traumatic stress disorders.
The behavioural scientist Professor Larry Young, of Emory University, Georgia, writing in the journal Nature, said: "For one thing, drugs that manipulate brain systems at whim to enhance or diminish our love for another may not be far away."
Experiments have already shown a nasal squirt of the hormone oxytocin enhances trust and tunes people into others' emotions.
