Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what the medical conditions are for which interspecies nuclear transfer has provided the first effective treatments; and how many admixed human embryo have been produced in each year since the Human Fertilisation and Embryology Act 2008.

There are no medical conditions for which interspecies nuclear transfer has provided effective treatments.

The Human Fertilisation and Embryology Authority (HFEA) has advised that, in 2008, 155 admixed embryos were produced in a HFEA licensed research project. No admixed embryos have been produced in HFEA licensed research projects in any other year to date.
