Oxytocin Makes Women Happy

Oxytocin has been long known to be associated with female psychology, particularly with regard to the reproduction processes – such as giving birth or having sex.  Now it seems that oxytocin could be linked to female happiness per se.  A graduate researcher in America studied the oxytocin levels of women before and after they were given $24 by a stranger.  Oxytocin levels rose in most of the women, but rose most in those women who were already happier in their lives.
