      ABSENCE MAKES MEN'S HEARTS grow fonder, but apparently not women's.
      Psychologists say this may be a strategy designed to help men outsmart an
      unfaithful partner.

      Males of most species can never be sure that the children they help to raise
      are their own. According to a 1995 study, men minimise the risk of unwittingly
      caring for another man's child by producing more sperm in their ejaculate the
      longer they have been away from their partner. It made no difference how long
      it had been since the couple last had sex.

      Todd Shackelford at Florida Atlantic University in Davie and his colleagues
      suspected that a psychological mechanism might trigger the increase in sperm
      production. To find the link between psychology and physiology they asked 692
      American and German men and women in committed heterosexual relationships to
      fill out an anonymous questionnaire.
