APPENDIX 92

Supplementary evidence from the Human Fertilisation and Embryology Authority

RESPONSES TO SUPPLEMENTARY QUESTIONS

1.  How do you see your role in facilitating and informing the research that is undertaken to support the Authority's policy decisions?

  The HFEA is not a research body. We do not have the budget or the expertise to conduct high level academic research. Clearly, because of our commitment to evidence based policy making, many of our policy reviews will contain an element of research, mostly literature reviews and at times also opinion research (both qualitative and quantitative). From time to time, the HFEA has commissioned research from outside experts to inform its policy making, again, this research mostly consisted of literature reviews (see question 7 below).

  In recent years, the HFEA has started to develop a more sustained approach towards the question of social science and epidemiological research. It initiated the MRC/HFEA working group that was explicitly tasked with identifying research needs and ways in which these could be met, and is taking follow-up action with the MRC. The HFEA has also supported an application by the National Perinatal Epidemiology Unit to the MRC for funding to conduct research into the long-term health outcomes for IVF children. Follow-up action is also being taken up with the MRC.

  We have now also identified and are starting to establish sustained working relationships with both the ESRC and Wellcome Trust in order to increase the knowledge and evidence base for the HFEA's policy making function and the fertility sector itself.

2.  How many people are currently employed in the HFEA's Regulation Department? How many vacancies are there? What efforts have been made to fill these vacancies?

  The Regulation Department is undergoing a period of sustained change and modernisation, and is investigating plans to move towards an in-house, full-time professional inspectorate. The current staffing structure is therefore under review. Once this review has concluded, it will become clearer how many positions—and of which type—there will be required.

  Currently, there are 20 people employed (this includes the Research Regulation Function, Clinical Governance, and administration functions) and two vacancies, with one more shortly to arise.

  One interim staff member has been recruited and further candidates are being interviewed to cover two of the vacancies. Advertisements for permanent staff are currently pending, subject to agreement by the Arms' Length Review.

3.  For what reasons have licences been refused or not renewed?

  It is relatively rare for licences to be revoked, less rare for licences not to be granted in the first place or renewed. It is more common for conditions to be imposed on licences. "Formal recommendations" don't become part of a centre's licence, but are another way in which a Licence Committee can give guidance to a clinic.

  Below is a list of typical reasons for which the HFEA Licence Committees have taken action in order to manage risks in clinics or labs.

RESEARCH LICENCES

Licence not granted

    —    Because there was no "research" angle, and the application was effectively about training ICSI or embryo biopsy practitioners (not within the law to grant such a licence, but we have flagged up that we would like to be given power to give such licences).

    —    Because the applicants couldn't demonstrate the required ability to select spermatids reliably.

    —    Because the Committee felt that the proposal was of "poor experimental design".

Licence not renewed

    —    Because the (then new) requirements to deposit stem cell lines in the MRC stem cell bank were not reliably met.

TREATMENT LICENCES

Licence not granted/altered

    —    Because guidelines on ICSI practitioners could not be altered to accommodate one clinic.

    —    Because of doubts about the suitability of the proposed PR.

    —    New centre not yet ready for licensing.

Licence revocation threatened

    —    Because centre didn't report data in accordance with general directions (centre took corrective action and the proposal was dropped).

    —    Because of a serious incident involving the use of the `wrong' sperm (centre took corrective action and the proposal was dropped).

Licence not renewed

    —    Because centre was small, very few patients and cycles.

Conditions put onto the licence

    —    Request for information regarding counsellor's qualifications.

    —    Full audit of stored gametes and embryos.

    —    Accredit lab staff.

    —    Introduce version control for patient information.

    —    Comply with section 8.14 of the Code of Practice for home sperm production.

    —    Make available a customised sperm production room.

    —    Comply with requirements of Deceased Fathers Act.

    —    Audit all patient records.

    —    Separate screened and unscreened samples.

Formal recommendations

    —    To develop counselling protocols.

    —    To change patient info.

    —    To change lab protocols.

    —    To get a new Dewar installed.

    —    To install a password protected database.

    —    To improve the management of consent procedures.

    —    To hide Dewar keys.

    —    To improve cryostore ventilation.

    —    To introduce witnessing protocols.

    —    To review and sign audit reports.

4.  What factors influence your decision to publish pregnancy rates for treatment centres?

  Section 8 of the HFE Act 1990 obliges the HFEA to provide information to the public about "services provided in pursuance of a licence" and to provide information and advice to persons who are receiving treatment services'. We have traditionally understood this to include outcome data from the all the licensed clinics.[374] The Authority does believe that in the context of other crucial information (such as what services are provided, pricing, locality etc) the information about treatment outcomes can play an important role in facilitating patient choice.

  However, it is clear that comparing outcomes (and thus defining "success") is difficult and that certainly "success rates" should not be read in isolation. This is why we set up a Clinical Information Working Group, consisting of representatives from centres, the professional bodies, patients and counsellors. This group decided that publishing outcome data should be continued, but that a single unified comparator (a "success rate") should not be included in this year's patients' guide. This is because it would reflect the wide range of embryo transfer practice before the introduction of the two embryo transfer policy in 2004.

5.  What was the result of your legal advice on the status of a pro-nucleus?

  Section 3(3)(d) prohibits "replacing a nucleus of a cell of an embryo with a nucleus taken from a cell of any person, embryo or subsequent development of an embryo". The question arose whether this prohibition also covered the transfer of the pronuclei from one zygote into an enucleated zygote (a one cell embryo).

  To answer the question, the HFEA considered the following information:

    —    Professors Ian Wilmut and Keith Campbell in their book: "The Second Creation" (Wilmut, Campbell and Tudge; 2000, Headline Books) state: "Note that the zygote at no stage contains a single nucleus. First, it has two haploid pronuclei, then two diploid pronuclei, and then it enters mitosis. There is no diploid nucleus, with a complete complement of chromosomes until we reach the two-cell stage" "one-celled embryos—do not contain single, diploid nuclei—"

    —    Furthermore, in one of the standard text books on developmental biology (Gilbert, SF Developmental Biology, Fifth Edition, 1997 Sinauer Associates Inc. Publishers) it states that "a true diploid nucleus in mammals is first seen not in the zygote, but at the two-cell stage."

    —    In addition, the Oxford English Dictionary defines a pronucleus as "either of a pair of gametic nuclei, in the stage following meiosis but before their fusion leads to the formation of a nucleus of the zygote".

  Therefore there is a biological distinction between a nucleus and a pronucleus.

  The HFEA also considered the following advice form Morgan Cole Solicitors:

    —  Paragraphs 12.11 of the Warnock Report referred to cloning by embryo splitting and paragraph 12.14 to cloning by means of nucleus substitution. Paragraph 38 of the White Paper made reference to both paragraphs 12.11 and 12.14 when setting out the intention to include an absolute prohibition in the Bill. However, as Lord Bingham pointed out in the Quintavalle case, Parliament did not actually introduce Section 3(3)(d) with the intention of banning all cloning. He pointed out that cloning by embryo splitting was not covered and that supported his conclusion that Section 3(3)(d) could not be construed so widely as to prohibit CNR. If the House of Lords had come to a contrary conclusion that the intention was to ban all cloning then that would have supported the prohibition extending to "pronucleus substitution". The approach adopted by the House of Lords suggests that a narrower construction is appropriate.

    —    Even if pronucleus substitution is not within Section 3(3)(d), the Act still applies regulatory control over any embryo that may be created. (It would still require a licence from the HFEA). Accordingly, it is not essential to the regulatory purposes of the Act that a pronucleus is regarded as a nucleus.

  It therefore seems that section 3(3)(d) does not cover the transfer of the pronuclei from one zygote into an enucleated zygote.

  However, schedule 2 para 3(4) provides that "a licence under this paragraph cannot authorise altering the genetic structure of any cell while it forms part of an embryo, except in such circumstance (if any) as may be specified in or determined in pursuance of regulations." It therefore seems that the transfer of the pronuclei from one zygote into an enucleated zygote is prohibited by schedule 2 para 3(4).

6.  Can you supply the data arising from your survey of UK clinics on the availability of donated gametes?

  The survey summary can be found on the HFEA website at:

  http://www.hfea.gov.uk/AboutHFEA/HFEAPolicy/SEEDReview/seed%20review.pdf .

7.  In 1993 you commissioned two pieces of work from Rachel Cooke and Susan Golombok, published as A Survey Of Semen: Phase I—The View Of UK Licensed Centres and A Survey Of Semen: Phase II—The View Of The Donors. What other research has the HFEA commissioned and why?

  As outlined above, the HFEA does not have a regular research budget and also does not have the necessary expertise, resources and statutory role to commission large-scale academic research. From time to time, and as part of wider policy reviews, the HFEA has commissioned small-scale research projects, mostly in the form of literature reviews.

  These include:

    —    2002, Olga BA van den Akker, BSc PhD C Psychol AFBPsS, Reader in Health Psychology: a literature review on donor conceived, step and adoption families.

    —    2002, Dr Lars Bjrndahl and Professor Chris Barratt: A review of the scientific and clinical literature on sex selection.

    —    2002, Dr Cathy Waldby: A review of the social and ethical literature on sex selection.

    —    2003, Professor Alison MacFarlane: A review of British and American data on embryo transfer and treatment outcomes.

8.  Can you provide the full costs for the Historical Audit Project and the number of staff employed, on an annual basis?

  The HFEA has statutory obligations under the HFE Act to establish and maintain a register. It is imperative that there is 100% accurate data about treatment outcomes on the register, in particular where donated gametes have been used, to give confidence to donor conceived children in the information provided.

  The historic difficulties with the HFEA's register are addressed through the Historical Audit Project. The new improved database which has been established through the Register Programme will enable many mistakes to be picked up straight away. We are also developing an Electronic Data Interchange, which eliminates the possibility of errors being introduced by HFEA and will make clinics' data reporting easier and faster in many ways. However, clinics are being asked to correct errors and omissions identified in previous information and future submissions.

  Although at least 40% of mistakes and omissions on patient forms have been introduced by clinics, we are trying to minimise the burden for centres through the Historic Audit Project. The HFEA provides the staff to perform this audit. However, we do believe that this ongoing historic audit represents a necessary effort, since the provision of reliable data is one of the most important functions of the HFEA.

  The Historic Audit costs are as follows:

  2004-05 projected outturn expenditure (as shown in the December Management Accounts): £1,547,000 with 57 staff in total by end of March 2005.

  2005-06 estimated budget (as shown in the Business plan): £3,236,000 with 58 staff as of April 2005.

9.  The minutes of the February 2003 meeting of the Authority report that "Discussion was held considering the HFEA role in research given that this function has never been in the HFEA remit or budget. There was a suggestion that the HFEA should undertake social research in relation to welfare of the child issues. It was agreed that the Authority should receive a paper on research priorities at its May meeting when future action concerning research should be decided." What did the Authority decide in relation to the commissioning of social research?

  The HFEA initiated the MRC/HFEA working group to identify medical and epidemiological research priorities. With regard to social science research, it is clear that the HFEA does not have the resources or expertise to conduct or commission large-scale academic research projects. From time to time, the HFEA will commission research, as part of wider policy reviews or consultations (see questions 1 and 7 above).

10.  Have you ever received a research application to culture an embryo beyond 14 days? If so, what decision was reached and why?

  No, we have never received an application to culture an embryo beyond 14 days. Scientific advice also tells us that it is currently impossible to keep embryos alive in vitro beyond 9 or 10 days.

  Were we to receive such an application, we would have to reject it under the current legislation (section 3, (3)(a) and (4) HFE Act 1990).

February 2005







374   No outcome data was published for the year 2001-03 because of problems that had arisen with the HFEA's register. Back
