Question to the Department of Health and Social Care:

To ask His Majesty's Government, further to the Written Answer by Lord Markham on 6 June (HL7725), how the implantation failure rate for pronuclear transfer compares to that for all other treatments regulated by the Human Fertilisation and Embryology Authority.

The Human Fertilisation and Embryology Authority has advised that it is not possible to compare the implantation failure rate for pronuclear transfer to all other treatments it regulates as the number to date is too low.
