Back to the love potions then?
I'd better get the old cauldron dusted down because I'll be rich
The recent Guardian article, http://www.guardian.co.uk/science/blog/2012/jul/03/oxytocin-trust-hormone?INTCMP=SRCH
, looks at related research with animals where the female releases oxytocin, which prompts her to 'treat her partner as special' whereas the male releases vasopressin, which prompts him to also 'treat her as special, and he becomes jealous and territorial'. But how to sustain that?
The recent BBC article, http://www.bbc.co.uk/news/uk-scotland-tayside-central-15262562
, reported on relationship satisfaction with female oral contraception use, which seems to be, inadvertently, already acting as a 'love drug' of sorts to keep women in relationships.
Dr Roberts said: "Our results show some positive and negative consequences of using the pill when a woman meets her partner.
"Such women may, on average, be less satisfied with the sexual aspects of their relationship, but more so with non-sexual aspects."
He added: "Overall, women who met their partner on the pill had longer relationships - by two years on average - and were less likely to separate.
