Notes:

  1. The data is as recorded by the HFEA on 10 May 2023, these figures reflect the data on this day and are likely to change over time.
  2. The HFEA publishes information which does not compromise patient confidentiality. All counts of less than five are not released as there is a significant possibility that when combined with other information which may be reasonably accessed, it could lead to the identification of a person to whom the HFEA owes a duty of confidentiality.
  3. Implantation failures is calculated as embryo transfer procedures subtracting where intrauterine foetal pulsations were recorded. This calculation does not account for chemical pregnancies as these are not recorded.
  4. This information has been banded as it could reasonably be used in combination with information already in the public domain to determine suppressed information in this table.
