'We have two test tubes here,' said the professor of IVF studies from Monash University.

'They contain two carefully synthesized ingredients that we can now use to create human life. Solution A is a genetically engineered copy of all the ingredients in the female ovum, while Solution B replicates the active ingredients in male spermatozoa.

'If I mix them in this aseptic glass container a new human life will be conceived. Now any questions?'
'Could you possibly give us a demonstration?' asked an awed member of the audience.
'I'm sorry, not tonight,' said the professor, 'Solution A has a headache.'
