To ask Her Majesty’s Government, further to the Written Answer by Viscount Younger of Leckie on 5 February (WA 58), what are the known sources of suffering experienced by non-human primates during pronuclear transfer; and to what extent they consider that human patients or their offspring might be expected to have similar experiences through the application of pronuclear transfer.

The Government does not hold this information and has neither funded or licensed pronuclear transfer in non-human primates.

Any research that might have been published in other countries will be available in scientific literature.
