Sex Selection: Choice and
Responsibility in Human Reproduction
This is the title of the latest public consultation exercise from
the Human Fertilisation and Embryology Authority (HFEA). It
is asking whether embryo sex selection techniques should be made
available for non-medical purposes. The public was last
consulted on this issue in 1993, when such non-medical sex
selection was rejected.
Sex
Selection - The Methods Used
Sex selection of children is not
new. Some societies, for example, especially in India and
China, currently practise it by infanticide – that is, they kill
their newborns, usually girls, within the first few days of their
birth, either deliberately by smothering or poisoning them, or by
simple abandonment. That is horribly crude, but
effective. Other societies use the less primitive method of
ultrasound scanning to determine the sex of the unborn child and
then use abortion to ‘get rid of it’. That is a rough and
ready, process but it works, mostly.
Now, we, in the West, have become far more sophisticated. We
can use techniques like preimplantation genetic diagnosis (PGD),
or sperm sorting. PGD is a fairly recent development in a
series of methods used to check on the health of the unborn – it
joins amniocentesis and chorion villus sampling in seeking out
those with genetic abnormalities that may lead to disability, who
are then typically destroyed by abortion. All three methods
are part of the ‘search and destroy’ mentality of prenatal
screening. The newcomer, PGD has to be used in combination
with in vitro fertilisation – one cell from an early human embryo
is removed, sent for chromosomal analysis and if it fails the
quality control test, that is, it is of the unwanted sex, then the
rest of the embryo is simply squashed.
Sex Selection - The Previous Consultation
In 1999, the HFEA held a public
consultation exercise on the use of PGD. The FIEC responded
– the full text can be read at
<www.fiec.org.uk/pgd.htm>. The following is one
pertinent paragraph from that response. The fear expressed
in the penultimate sentence is now upon us, big time.
The Slippery Slope Argument
In some bioethical circles this is
a much-maligned concept; we disagree. We remember the
legal changes made in the 1967 Abortion Act, which gave
permission, under limited circumstances, to women seeking
termination of their pregnancies. That initial permission
has since become an expectation with hundreds of thousands using
the poorly-defined grounds. Legalisation creates a
demand. Furthermore, the Human Fertilisation and
Embryology Act (1990) initially appeared to be the basis for
strict regulation in some areas. Yet, additional
techniques, some novel, if not bizarre, circumstances, a lack of
public awareness and an inability to legislate for a fast-moving
technology from a clear and solid ethical framework have shown
this piece of legislation to be repeatedly ineffective. We
fear the same for PGD. Once approved it will be impossible
to maintain boundaries. It will be impossible to define
“severe” and “significant” with respect to genetic
disorders. “Severity creep” will undoubtedly occur.
And whose assessment of severity will count? It clearly
will not be the patient’s, so will it be the doctor’s, the
parent’s, or society’s? Within a few years screening for
more and more potential diseases, as well as sex determination,
will be widespread with the consequence of more and more genetic
discrimination. Eventually, other genetic aspects, such as
behavioural disorders, that commissioning parents find
unacceptable will also have to be included in such testing.
The upshot of that 1999 consultation was that, despite the
opposition by many, Parliament approved the use of PGD in the UK
for medical reasons, such as the avoidance of X-linked diseases,
like haemophilia and Duchenne’s muscular dystrophy.
So sex selection, via PGD, is already happening in a limited way,
but it could soon be on a grander scale. This is because of
the advent of a new technique for sperm sorting – it is the cause
of the latest bioethical commotion. But sperm sorting itself
is not new. In 1993, it was brought to this country by the
London Gender Clinic. However, its technique was not very
efficient, about seventy per cent, and expensive, about £650 a
go. The Clinic closed down fairly rapidly.
Sex
Selection - The New Challenge
Enter MicroSort - this is the new,
more reliable and cheaper method of sperm sorting. It has
been pioneered by The Genetics and IVF Institute in
Virginia. This Institute has helped at least 300 couples
choose the sex of their babies before fertilisation. And
apparently six UK couples have already gone to Virginia to have
either a boy or a girl of their choice, well almost - MicroSort is
claimed to be ninety-one per cent accurate.
The two genes that determine a child’s sex come from the mother’s
ovum (which is always an X chromosome) plus the father’s sperm
(which can be either an X or a Y chromosome). If the ovum is
fertilised by an X-carrying sperm, the result will be a
daughter. If a Y-carrying sperm fertilises the ovum, a son
will be conceived. Sperm sorting works because the
possession of an X or a Y chromosome affects the amount of DNA
that a particular sperm contains. On this basis, 'male' and
'female' sperm can be separated because the latter are 'heavier',
or they can be sorted with the aid of a fluorescent dye and a
laser. Either a son or a daughter can then be ‘created’
using the appropriate X or Y sperm.
With the imminent arrival of MicroSort, and other similar
procedures, into the UK, the HFEA has arranged this latest
consultation to consider the rights and wrongs of selecting the
sex of future children for non-medical reasons. It often
goes under the euphemism of ‘family balancing’. A couple
already have two sons, why can they not be guaranteed a daughter
next time round? Currently, there is nothing to stop
MicroSort, or similar methods, being used in the UK. The
1990 Human Fertilisation and Embryology Act covered aspects of
assisted reproduction using only frozen or donated sperm, but not
fresh sperm. Does the law need changing?
If we already allow sex selection on medical grounds, then why not
on non-medical grounds? Do these techniques declare that the
disabled are inferior people? If used in conjunction with
IVF, what happens to embryos of the ‘wrong’ sex? Is this a
further step down the eugenics road? Is choosing the sex of
children who do not yet exist a weird enterprise? Does it
amount to control and design, rather than nurture, by
parents? Is it not blatant sex discrimination? These
are the sorts of questions that need to be considered.
Sex
Selection - What Do You Think?
So this is your chance to make your
mind up and respond to the HFEA document. This is what
responding to the culture of death is all about! The HFEA
Consultation Document can be found at <www.hfea.gov.uk>,
click on ‘Consultations’. Then you have a choice of either
the whole 39-page Document plus the questionnaire (in pdf), or
just the online questionnaire. It will take only about two
hours to read the full Document and begin to think about the
issues. A good strategy might be to then discuss it with
others from your fellowship, either formally, or informally.
Then there are a mere eight questions to answer.
You have until 22 January 2003 to reply. This is an
excellent opportunity to clarify your thinking and formulate a
coherent response. Just imagine what would happen if all
FIEC churches and a few hundred individual Christians replied –
the HFEA would be taken aback. If you sit on your hands,
nothing will change. So, go on, go on, go on!
