To ask Her Majesty’s Government, further to the Written Answers by Lord Prior of Brampton on 8 November (HL2858 and HL2861), why the data provided by the Human Fertilisation and Embryology Authority (HFEA) in table 3 of the first of those answers detail that no live births resulted from frozen donated oocytes between 2008–14, whereas the data provided by the HFEA included in the second of those answers detail that in relation to treatments that took place prior to 30 June 2014, 72 patients aged 35 and over using donated frozen oocytes had a live birth.

Further to the Written Answers of 8 November, officials have advised that, due to administrative error, the information relating to live births shown in Table 3 was incorrect. A revised version of the table is shown below:
