PGD: 
Genetic testing performed prior to embryo transfer 
“The debate [around 
PGD] has been building 
since the late 1980s, 
when doctors at 
London's Hammersmith 
Hospital learned how to 
tease a cell from a 3- 
day-old embryo and 
study its chromosomes 
for gender.” 
(Zitner 2002) •Adds $2000 to IVF 
•Reduces rate of miscarriages from 23% to 10% 
•Does not increase chance of pregnancy
Commonly, more than 100 diseases 
can be detected through testing, 
including… 
• Hemophilia A 
• Muscular dystrophy 
• Tay-Sachs disease 
• Cystic fibrosis 
• Down Syndrome

Production mentality is a problem. “Where amniocentesis usually provides 
information about a single fetus, embryo screening allows parents to judge and 
reject many potential children at once. And because it bypasses the pain of abortion, 
some fear it will be used too freely, coarsening attitudes toward the embryo.” 
Fetuses become products rather than children. (Zitner 2002)

…weighing the goal of 
pregnancy and live 
birth against the

• Address the suffering of the mother 
due to her inability to have a child 
“naturally” 
• “When having children, people… 
often roll the genetic dice and hope 
for the best. With embryo sorting, 
"they can start their pregnancy on 
Day One with a commitment to 
continuing it." 
(Zitner 2002) 
• PGD can save parents massive 
heartbreak and financial strain 
ethics 
• Address the view of the potential 
child 
– Will the child have adequate support 
and a stable home? 
– If there are multiple fetuses, will the 
children receive adequate 
care/attention? 
• “[PGD has] the laudable goal of 
stopping deadly genetic diseases 
such as Tay-Sachs and 
Huntington’s. This research has 
growing support because it can 
save children from enormous 
suffering and early death.” 
(Wagner 2003) 
Some ethicists would be in favor of IVF and PGD as long as 
the decision is loving and promotes positive relationships.
Engineering 124; 
Spring 2003 
Definition of Moral Community 
for Rights Based Ethics 
Before one can decide to whom rights apply, one must determine 
the moral community. 
“As individuality is a sine qua non for personhood, it seems safe to consider 14 
days of normal embryonic development to be the minimum requirement before 
a human being can emerge. Other criteria might place the earliest time point at 
a later stage, for example, 28 days, when the neural tube closes and the 
development of the central nervous system necessary for rationality begins. Or, 
with Aristotle and St. Thomas Aquinas, one might consider 40-90 days of 
development to be necessary to allow a human soul to be present; or as the 
Roman Catholic Church taught for centuries, one might require body-form and 
movement to be present before full human status was recognized.” (J.E.S.Hansen) 
Therefore, embryos lack rights as individuals because they 
are not part of the moral community. 
11
Engineering 124; 
Spring 2003 
Rights Based Ethics 
Embryos are mass-produced, screened, discarded and used in 
experiments: are they products or people with rights? 
According to Hansen (see previous slide), the treatment of embryos is not an issue. 
Based on John Locke’s principles, all people have the right (in America) to “life, 
liberty and the pursuit of happiness.” 
•What becomes of the idea that everyone is created equal if you start designing 
children? 
•Loss of autonomy because of a necessity to be competitive in society 
•Inherently discriminatory; makes assumptions about quality of life 
"Most people with disabilities rate their quality of life as much higher than 
other people think. People make the decision [to reject embryos] based on a 
prejudice that having a disability means having a low quality of life.“ 
(Zitner 2002) 
12
Engineering 124; 
Spring 2003 
Utilitarianism 
The greatest good for the greatest number suggests that… 
• The alleviation of suffering for 
many is important. 
– IVF helps many infertile couples 
achieve a life-long dream of 
having a child. 
– PGD helps those same couples 
reach their goal of a disease free 
child. 
• A disease free society is 
preferable for all members. 
13
What does religion have to say 
Engineering 124; 
Spring 2003 
about Embryo technology? 
14 
• The Christian view: 
• Life is sacred 
• Only God should 
create life and take 
it away. 
• God knows you even 
when you are in the 
womb...
Engineering 124; 
Spring 2003 
• You created every 
part of me; you put 
me together in my 
mother’s womb... 
When my bones 
were being formed... 
when I was growing 
there in secret, you 
knew that I was 
there. 
• Psalm 139: 13-16 
15
Engineering 124; 
Spring 2003 
Do all Christians have the same 
opinion about Embryo technology? 
• Roman Catholic Church: thinks 
embryo technology is wrong. This is 
because you are a person from the 
moment of conception. 
• Church of Scotland:does think that 
life is sacred but agrees with using 
embryos until the 14th day of 
development. 
• Both churches disagree with the idea 
of designer babies 
16
Engineering 124; 
Spring 2003 
17
Engineering 124; 
Spring 2003 
….Christian View 
• The Church of Scotland teaches that 
life must be protected from the 
moment of conception. Genetic 
engineering for cosmetic purposes is 
rejected because it is ’playing God’ to 
decide which people are to be valued 
and which are not. Medical research 
up to 14 days is accepted. 
18
Engineering 124; 
Spring 2003 
The Muslim View 
19 
• Life is a gift from Allah. 
• He breathes life into the 
embryo, this when you 
become a person. 
• Some Muslims think this 
happens on the 42nd day of 
development. Others say 
it is on the 120th day.
Engineering 124; 
Spring 2003 
20 
Muslim View 
• Life is sacred and a gift from Allah – 
Surah 17:33, 40:70 
• How we treat other living things 
throughout life will form our 
judgement by Allah 
• There is disagreement about when 
Allah breathes life into the foetus so 
some accept research up to a certain 
stage.
Engineering 124; 
Spring 2003 
• Some Muslims agree with embryo 
research. 
• Some say that Allah has given humans 
intelligence. We should use this to make 
life better: if you can make someone’s life 
better by using embryo research then you 
should. 
• Some argue therefore, that using pre-embryo's 
or embryos for research is 
acceptable if the possible benefits are 
great enough. 
21
Engineering 124; 
Spring 2003 
Embryo research and UK law 
• Licenses for embryo research must 
be provided by the HFEA (Human 
Fertilization and Embryology 
Authority) 
• Research is allowed up to 14 days of 
development 
• Frozen embryos can only be stored 
for up to 5 years. 
22
Why are human embryo’s used 
Engineering 124; 
Spring 2003 
for research? 
• Gives more accurate picture of how the 
illness/treatment might affect a 
person. 
• The research could help to eliminate 
diseases such as Parkinson’s and 
Alzheimer’s. 
• The embryo is not a human being , just 
a collection of cells, so it is acceptable 
to extract genetic material form it and 
use it to benefit others. 
23
Do human embryo’s have 
Engineering 124; 
Spring 2003 
rights? 
• No: it is only a cluster of cells, not 
a person. Only a person has rights. 
It has no awareness or feelings. 
• Yes: It is a potential human being 
and deserves to be respected. Life 
begins at conception. 
24
Engineering 124; 
Spring 2003 
Other Views on Embryo research: 
• British Humanist Association 
• Spare embryos produced through fertility 
treatment are routinely disposed of, so it 
is better that they are used to benefit 
other people. 
• Embryo is fertilized egg with potential to 
be a person but it has no self-awareness, 
no ability to feel pain or emotion. 
Therefore it cannot suffer. 
25
Engineering 124; 
Spring 2003 
Peter Singer (Preference Utilitarian) 
• We already allow this kind of treatment. 
It has benefited many people. 
• Individuals should be free to make their 
own choices on this issue as it is a private 
matter harming no-one else. 
• Many children have been born as a result 
of this technology. It hasn’t harmed any 
of them or society so we should conclude 
that it is acceptable. 
26
Engineering 124; 
Spring 2003 
Mary Warnock (Philosopher) 
• Immense benefits come from using human 
embryos therefore it is right that they are 
used. 
• The key stage of embryo development is 
the ‘primitive streak’ at 14 days. 
• The ‘slippery slope’ argument is not valid as 
there are specific laws to stop this 
happening , eg the ’14 day rule’ 
27
Engineering 124; 
Spring 2003 
International Policies on PGD 
•Banned PGD for ALL usages 
•Used to select child’s 
gender only when 
there is medical need 
28 
•Clinics set policies; no 
federal or state restrictions

What is your opinion? 
29
Questions: answer these fully in 
Engineering 124; 
Spring 2003 
your jotters. 
1. Name two ways in which Christians 
and Muslims agree about embryo 
research 
1. When does the Catholic Church 
30 
think that life begins?
Engineering 124; 
Spring 2003 
Describe UK law relating to the 
use of human embryos in 
research. 
• Human cloning is not allowed. 
• Therapeutic cloning is allowed. 
• Licences must be provided by the 
HFEA. 
• Research allowed up to 14 days of 
development. 
• Frozen embryos can only be stored for 
up to 5 years. 
31
Describe a secular viewpoint in 
relation to genetic selection 
Engineering 124; 
Spring 2003 
• Peter Singer (a Utilitarian) 
• We already allow genetic selection by encouraging 
prenatal diagnosis of conditions such as Downs 
Syndrome as this often leads to selective abortion. 
• If humans have already developed the ability to 
prevent certain genetic disorders then we should use 
this technology to benefit people. 
• Individuals should be free to make their own choices 
on this issue as it is a private matter harming no one 
else. 
• However, Singer also points out that human genetic 
engineering may lead to a loss of diversity among 
human beings. This may reduce humanity's capacity 
to adapt to changing circumstances. 
32
Engineering 124; 
Spring 2003 
• This may also lead to an increasing gap 
between rich and poor in society as the 
children of the rich, who can afford to 
genetically enhance their offspring, gain 
more advantages over the children of the 
poor. 
• Singer suggests the State should control 
human genetic engineering so that everyone 
can share in the benefits. 
33
Engineering 124; 
Spring 2003 
What arguments might 
scientists use to support using 
human embryos in research? 
• A human embryo gives a more accurate 
picture of how the illness/treatment may 
affect a person. 
• The embryo is not a human being but only a 
collection of cells. 
• It has no self-awareness, thoughts, 
internal organs etc. Therefore, material 
can be extracted to benefit others. 
• The research could help to eliminate 
diseases such as Parkinson’s, Alzheimer’s 
and even cancer. 
34
Engineering 124; 
Spring 2003 
How far does the religious viewpoint you have 
studied agree with using embryos for stem 
cell research 
• Only God has the right to create life. 
Whenever humans try to behave like God 
they mess up. 
• Humans are made in God’s likeness – 
Genesis 1:27. 
• ‘Do not commit murder’ – Exodus 20:13. 
• Life is sacred and should only be ended by 
God – Job 1:21. 
• God cares for the developing foetus – 
Psalm 139:13-16. 
35
Engineering 124; 
Spring 2003 
• The Roman Catholic Church teaches that 
life begins at conception. Therefore life 
must be protected from the moment of 
conception. However, gene therapy is 
acceptable where it is of medical benefit. 
• The Church of Scotland teaches that life 
must be protected from the moment of 
conception. Genetic engineering for 
cosmetic purposes is rejected because it is 
‘playing God’ to decide which people are to 
be valued and which are not. 
36
Engineering 124; 
Spring 2003 
• The Church of Scotland does accept 
medical research up to 14 days. 
• The Bible also teaches that Christians 
should be compassionate towards others 
leading some to suggest that this includes 
medical research if it can provide cures for 
diseases or help those with fertility 
problems. 
37
Engineering 124; 
Spring 2003 
• Islam 
• Agree 
• Life is sacred and a gift from Allah – 
Surah 17:33, 40:70. 
• How we treat other living things 
throughout life will form part of our 
judgement by Allah. 
38
Engineering 124; 
Spring 2003 
• However 
• There is disagreement about when 
Allah breathes life into the foetus so 
some accept research up to a certain 
stage 
39
How might medical scientists 
Engineering 124; 
Spring 2003 
define an embryo? 
• A fertilised egg from 14 days to 8 
weeks. 
• The Human Fertilisation and 
Embryology Act defines an embryo as 
a live human embryo where 
fertilisation is complete. 
• or 
• An egg in the process of fertilisation.

And because it bypasses the pain of abortion, some fear it will be used too freely, coarsening attitudes toward the embryo.” Fetuses become products rather than children.

  • 9. Engineering 124; Spring 2003 World Views …requires society to make a decision on when life begins. 9 Rights Ethics Utilitarianism Ethics: The issues at hand… Care Ethics …weighing the goal of pregnancy and live birth against the medical and moral risks of multiple gestation. …using PGD inherently makes assumptions about the quality of life, challenging basic tenets of society such as equality.
  • 10. Engineering 124; Spring 2003 10 • Address the suffering of the mother due to her inability to have a child “naturally” • “When having children, people… often roll the genetic dice and hope for the best. With embryo sorting, "they can start their pregnancy on Day One with a commitment to continuing it." (Zitner 2002) • PGD can save parents massive heartbreak and financial strain ethics • Address the view of the potential child – Will the child have adequate support and a stable home? – If there are multiple fetuses, will the children receive adequate care/attention? • “[PGD has] the laudable goal of stopping deadly genetic diseases such as Tay-Sachs and Huntington’s. This research has growing support because it can save children from enormous suffering and early death.” (Wagner 2003) Some ethicists would be in favor of IVF and PGD as long as the decision is loving and promotes positive relationships.
  • 11. Engineering 124; Spring 2003 Definition of Moral Community for Rights Based Ethics Before one can decide to whom rights apply, one must determine the moral community. “As individuality is a sine qua non for personhood, it seems safe to consider 14 days of normal embryonic development to be the minimum requirement before a human being can emerge. Other criteria might place the earliest time point at a later stage, for example, 28 days, when the neural tube closes and the development of the central nervous system necessary for rationality begins. Or, with Aristotle and St. Thomas Aquinas, one might consider 40-90 days of development to be necessary to allow a human soul to be present; or as the Roman Catholic Church taught for centuries, one might require body-form and movement to be present before full human status was recognized.” (J.E.S.Hansen) Therefore, embryos lack rights as individuals because they are not part of the moral community. 11
  • 12. Engineering 124; Spring 2003 Rights Based Ethics Embryos are mass-produced, screened, discarded and used in experiments: are they products or people with rights? According to Hansen (see previous slide), the treatment of embryos is not an issue. Based on John Locke’s principles, all people have the right (in America) to “life, liberty and the pursuit of happiness.” •What becomes of the idea that everyone is created equal if you start designing children? •Loss of autonomy because of a necessity to be competitive in society •Inherently discriminatory; makes assumptions about quality of life "Most people with disabilities rate their quality of life as much higher than other people think. People make the decision [to reject embryos] based on a prejudice that having a disability means having a low quality of life.“ (Zitner 2002) 12
  • 13. Engineering 124; Spring 2003 Utilitarianism The greatest good for the greatest number suggests that… • The alleviation of suffering for many is important. – IVF helps many infertile couples achieve a life-long dream of having a child. – PGD helps those same couples reach their goal of a disease free child. • A disease free society is preferable for all members. 13
  • 14. What does religion have to say Engineering 124; Spring 2003 about Embryo technology? 14 • The Christian view: • Life is sacred • Only God should create life and take it away. • God knows you even when you are in the womb...
  • 15. Engineering 124; Spring 2003 • You created every part of me; you put me together in my mother’s womb... When my bones were being formed... when I was growing there in secret, you knew that I was there. • Psalm 139: 13-16 15
  • 16. Engineering 124; Spring 2003 Do all Christians have the same opinion about Embryo technology? • Roman Catholic Church: thinks embryo technology is wrong. This is because you are a person from the moment of conception. • Church of Scotland:does think that life is sacred but agrees with using embryos until the 14th day of development. • Both churches disagree with the idea of designer babies 16
  • 18. Engineering 124; Spring 2003 ….Christian View • The Church of Scotland teaches that life must be protected from the moment of conception. Genetic engineering for cosmetic purposes is rejected because it is ’playing God’ to decide which people are to be valued and which are not. Medical research up to 14 days is accepted. 18
  • 19. Engineering 124; Spring 2003 The Muslim View 19 • Life is a gift from Allah. • He breathes life into the embryo, this when you become a person. • Some Muslims think this happens on the 42nd day of development. Others say it is on the 120th day.
  • 20. Engineering 124; Spring 2003 20 Muslim View • Life is sacred and a gift from Allah – Surah 17:33, 40:70 • How we treat other living things throughout life will form our judgement by Allah • There is disagreement about when Allah breathes life into the foetus so some accept research up to a certain stage.
  • 21. Engineering 124; Spring 2003 • Some Muslims agree with embryo research. • Some say that Allah has given humans intelligence. We should use this to make life better: if you can make someone’s life better by using embryo research then you should. • Some argue therefore, that using pre-embryo's or embryos for research is acceptable if the possible benefits are great enough. 21
  • 22. Engineering 124; Spring 2003 Embryo research and UK law • Licenses for embryo research must be provided by the HFEA (Human Fertilization and Embryology Authority) • Research is allowed up to 14 days of development • Frozen embryos can only be stored for up to 5 years. 22
  • 23. Why are human embryo’s used Engineering 124; Spring 2003 for research? • Gives more accurate picture of how the illness/treatment might affect a person. • The research could help to eliminate diseases such as Parkinson’s and Alzheimer’s. • The embryo is not a human being , just a collection of cells, so it is acceptable to extract genetic material form it and use it to benefit others. 23
  • 24. Do human embryo’s have Engineering 124; Spring 2003 rights? • No: it is only a cluster of cells, not a person. Only a person has rights. It has no awareness or feelings. • Yes: It is a potential human being and deserves to be respected. Life begins at conception. 24
  • 25. Engineering 124; Spring 2003 Other Views on Embryo research: • British Humanist Association • Spare embryos produced through fertility treatment are routinely disposed of, so it is better that they are used to benefit other people. • Embryo is fertilized egg with potential to be a person but it has no self-awareness, no ability to feel pain or emotion. Therefore it cannot suffer. 25
  • 26. Engineering 124; Spring 2003 Peter Singer (Preference Utilitarian) • We already allow this kind of treatment. It has benefited many people. • Individuals should be free to make their own choices on this issue as it is a private matter harming no-one else. • Many children have been born as a result of this technology. It hasn’t harmed any of them or society so we should conclude that it is acceptable. 26
  • 27. Engineering 124; Spring 2003 Mary Warnock (Philosopher) • Immense benefits come from using human embryos therefore it is right that they are used. • The key stage of embryo development is the ‘primitive streak’ at 14 days. • The ‘slippery slope’ argument is not valid as there are specific laws to stop this happening , eg the ’14 day rule’ 27
  • 28. Engineering 124; Spring 2003 International Policies on PGD •Banned PGD for ALL usages •Used to select child’s gender only when there is medical need 28 •Clinics set policies; no federal or state restrictions
  • 29. Engineering 124; Spring 2003 What is your opinion? 29
  • 30. Questions: answer these fully in Engineering 124; Spring 2003 your jotters. 1. Name two ways in which Christians and Muslims agree about embryo research 1. When does the Catholic Church 30 think that life begins?
  • 31. Engineering 124; Spring 2003 Describe UK law relating to the use of human embryos in research. • Human cloning is not allowed. • Therapeutic cloning is allowed. • Licences must be provided by the HFEA. • Research allowed up to 14 days of development. • Frozen embryos can only be stored for up to 5 years. 31
  • 32. Describe a secular viewpoint in relation to genetic selection Engineering 124; Spring 2003 • Peter Singer (a Utilitarian) • We already allow genetic selection by encouraging prenatal diagnosis of conditions such as Downs Syndrome as this often leads to selective abortion. • If humans have already developed the ability to prevent certain genetic disorders then we should use this technology to benefit people. • Individuals should be free to make their own choices on this issue as it is a private matter harming no one else. • However, Singer also points out that human genetic engineering may lead to a loss of diversity among human beings. This may reduce humanity's capacity to adapt to changing circumstances. 32
  • 33. Engineering 124; Spring 2003 • This may also lead to an increasing gap between rich and poor in society as the children of the rich, who can afford to genetically enhance their offspring, gain more advantages over the children of the poor. • Singer suggests the State should control human genetic engineering so that everyone can share in the benefits. 33
  • 34. Engineering 124; Spring 2003 What arguments might scientists use to support using human embryos in research? • A human embryo gives a more accurate picture of how the illness/treatment may affect a person. • The embryo is not a human being but only a collection of cells. • It has no self-awareness, thoughts, internal organs etc. Therefore, material can be extracted to benefit others. • The research could help to eliminate diseases such as Parkinson’s, Alzheimer’s and even cancer. 34
  • 35. Engineering 124; Spring 2003 How far does the religious viewpoint you have studied agree with using embryos for stem cell research • Only God has the right to create life. Whenever humans try to behave like God they mess up. • Humans are made in God’s likeness – Genesis 1:27. • ‘Do not commit murder’ – Exodus 20:13. • Life is sacred and should only be ended by God – Job 1:21. • God cares for the developing foetus – Psalm 139:13-16. 35
  • 36. Engineering 124; Spring 2003 • The Roman Catholic Church teaches that life begins at conception. Therefore life must be protected from the moment of conception. However, gene therapy is acceptable where it is of medical benefit. • The Church of Scotland teaches that life must be protected from the moment of conception. Genetic engineering for cosmetic purposes is rejected because it is ‘playing God’ to decide which people are to be valued and which are not. 36
  • 37. Engineering 124; Spring 2003 • The Church of Scotland does accept medical research up to 14 days. • The Bible also teaches that Christians should be compassionate towards others leading some to suggest that this includes medical research if it can provide cures for diseases or help those with fertility problems. 37
  • 38. Engineering 124; Spring 2003 • Islam • Agree • Life is sacred and a gift from Allah – Surah 17:33, 40:70. • How we treat other living things throughout life will form part of our judgement by Allah. 38
  • 39. Engineering 124; Spring 2003 • However • There is disagreement about when Allah breathes life into the foetus so some accept research up to a certain stage 39
  • 40. How might medical scientists Engineering 124; Spring 2003 define an embryo? • A fertilised egg from 14 days to 8 weeks. • The Human Fertilisation and Embryology Act defines an embryo as a live human embryo where fertilisation is complete. • or • An egg in the process of fertilisation. 40
