Speaking to the Sunday Telegraph, he said: ‘The vast majority of women who will choose IVF in the future will be fertile women who have frozen their eggs and delayed pregnancy.

‘I predict that many of these women will be fertilised by IVF methods because of the advances in genetic screening. And once that happens then IVF will start to become a normal non-coital method of having children.’

He added: ‘For them, the separation between sex and reproductions will be 100 per cent.’

Professor Djerassi also predicted there will be more IVF fertilisations among fertile women in the next few decades – ‘say by 2050’ – than there currently is among those who are fertility-impaired.
