1. IVF and Stem Cell Research Bath Abbey Lent Lectures
22 March 2010
2. ‘A brave new world’? A transformation in medical diagnosis and treatment
Discovery of DNA revolutionised knowledge and potential applications
Mixed feelings!
“The little boy that science won’t save!”
“Spare parts supermarket!”
“Playing God” or being human?
3. The embryo as an epicentre IVF and Assisted Reproductive Technologies in forefront
From IVF to embryo selection, stem cells, saviour siblings, cloning, admixed embryos, cybrids and chimeras!
Massively complex – science and ethics
Christians take different positions!
4. Beginning with IVF 3 million plus children born with the assistance of IVF
Enabling infertile couples to conceive and give birth
Not straightforward for some!
Oliver O’Donovan: threat to integrity of reproduction and its purpose
5. Christian objections to IVF Dissecting strands of parenthood – if coupled with donors and surrogacy, many ‘parents’
From ‘begotten’ to ‘made’?
A ‘creature’ rather than ‘gift’?
RC theologians and IVF: ‘an unworthy method for the coming forth of a new life’
Taking place ‘in a context totally separated from conjugal love’
6. What happens to ‘spare embryos’? Gravest concern came from creating excess embryos
Donate, discard or experiment?
The Absolutist position: From fertilisation the embryo is a fully human person
Experimentation is anathema!
Widely held position among Christians
7. A different perspective The ‘gradualist’ position
Attempts to take in scientific understanding of development
Pre-14 day embryo not ‘individuated’ or ‘persons’
Pre-14 day embryo has special status and should be respected and protected
But not sacrosanct
8. A ‘theological embryology’ “.. the time from which the embryo should be afforded the same degree of respect and protection as those made in God’s image remains a matter of informed moral judgement. This is because the designation of being in the image of God is finally God’s judgement as it is a gift of God’s grace and not due to the embryo’s possession of any abilities or powers.” Revd Dr Stephen Bellamy
9. A slippery slope getting greasier? Gradualist understanding enabled many Christians to accommodate and support IVF
But was it now a ‘slippery slope’?
Advent of Preimplantation Genetic Diagnosis (PGD)
Selection of embryos by identifying markers
Used to screen out those with life threatening diseases
10. Concerns over PGD Discrimination and eugenics by the back door?
PGD not devalue lives of those with disease
PGD not imply some should not be born
Legitimate expression of parental love and responsibility
Commodification and designer babies?
Life-threatening disease not about whim or personal desire
11. But some concerns persist Carriers – a disease gene which is recessive
Cystic fibrosis – two carriers; 1 in 4 chance
Task Force of ESHRE: not select carriers
“spare offspring the burden of having to make similar decisions for their own offspring”
Introduces a further reason for selection
Makes a judgement about healthy embryos
Treating embryos more lightly plus impact
12. Saviour siblings Much greater controversy
Two cases to the HFEA
Brothers had bone marrow diseases
Parents asked for tissue matched embryo
Cord blood used as graft for brother
One turned down – subject of headline
But disease not affecting sibling (‘mutation’)
13. Crossing the boundary? Does the sibling become a ‘means to an end’?
What reaction, including psychological?
Freedom of child infringed or outworking of love and care for sake of healing?
New Embryology Bill taken further
Disease severe not only life-threatening
Sibling does not have to be at risk
14. An acceptable instrumentality? Parents wanting child for him/herself
Desire for a tissue type not overshadowing child as end in her/himself
“Thus we conclude that tissue typing of itself does not instrumentalise a child or prevent him being welcomed with agape love and cared for as an end in himself.” Bellamy
15. Other issues connected with PGD Genes and their penetrance
How much risk of disease before selection?
Jodi Picoud and ‘My sister’s keeper’
16. Hello Dolly! As if this were not complicated enough!
Dolly the sheep and the possibility of cloning
The therapeutic potential of embryonic stem cells
Cloning meets embryonic stem cell technology – human/animal embryos
17. Embryonic stem cells Stem cells in the earliest stages of embryo
Truly pluripotent – progenitors of any tissue
Stem cells for deriving lines of cells for transplant (eg brain and nervous system)
Obtaining ESC means destroying embryo
Creating embryos purely for ESC?
18. The issue of end or instrument? ‘Spare’ embryos as ends in themselves
Creating embryos makes them purely instruments
19. Different kinds of clone Reproductive cloning as anathema and illegal
Therapeutic cloning ethically acceptable
Transferring ‘somatic’ nuclear material to an egg without its own nucleus (‘enucleated’)
Artificial and asexual but needs regulating and protecting (potential human being)
20. Human and animal embryos? High ‘yuk’ factor!
Few human eggs and ethical issues
Possibility of using rabbit or bovine (cow) eggs
No nucleus so ESC largely human
Highly speculative
Ambiguity of status – cow, human or what?
Artificial, asexual but concerns
21. IVF and the ‘right to children’ Worrying trend of children as right not gift
Choice and utilitarian persepctives
New Bill and role of fathers
Single or lesbian couples right to IVF
‘Removing anomalies and discrimination’
What of a child’s right to have a father?
Social engineering?
22. The future? Sperm from female stem cells?
Mitochondrial donors?
Pressures from lobby groups (patients and scientists)
Pressures from commercial advantage
How can Christians respond?
Are they able to engage?
23. Tom Torrance in 1984 “In experimentation with human fetuses, in the manipulation of human embryos, in test-tube fertilisation, in the cross fertilisation of human with non-human species, in surrogate motherhood, medical science has brought us to an ultimate boundary beyond which a civilised and God-fearing country committed to the sanctity of marriage and the structure of the human family, may not go.”
24. Tom Torrance “What is at stake is nothing less than the future of the human race, but what is also at stake in the integrity of the scientific and moral conscience.”
25. Where is the Church? Not much change in Christian engagement
Conservative views harden – Reformed or Catholic
But lines between more conservative and more liberal breaking across usual divides
Engagement more easy with Gradualist approach
How can Absolutists contribute too?
26. Thank you for your attention
