Designer babies may be an option in massive fertility law shake-up
The biggest shake-up of Britain's fertility laws for 15 years could usher in an
era when couples may be able to choose the sex and possibly the genes of their
The Government highlighted more than 70 fertility issues yesterday that are to
be totally reappraised in its proposed update of the 1990 Human Fertilisation
and Embryology Act - a law formulated after the Warnock Report of 1985.
For the first time, ministers are contemplating the possibility of allowing
scientists to alter the genes of future generations as part of a reappraisal of
the blanket ban on altering the genetic structure of embryos.
The public consultation document published by the Department of Health also
raises the possibility of allowing research on human embryos such as the
creation of animal-human "chimeric" embryos.
Ministers also want the public to submit its views on whether couples should be
able to use embryo-screening or sperm-sorting techniques to choose the sex of
their unborn babies.
Although the document emphasises that it is not the Government's intention to
rewrite the existing fertility laws wholesale, the aim is to allow the law to
keep pace with a fast-moving field of medical science.
Caroline Flint, the public health minister, said that the 1990 Fertility Act
governing in-vitro fertilisation (IVF) technology was a landmark piece of
legislation but, in the past 15 years, the science had changed along with
"The Act has done a good job in taking public confidence with it but we need to
take stock. We need to strike the right balance," Ms Flint said. "We never
expected that the Act would remain forever unchanged in the face of major
developments in science and medicine," she said.
The existing law bans the alteration of the genetic structure of any cell that
is part of a human embryo but the Government wants to test public opinion to
see whether it could be allowed for research purposes.
It also points out it may soon be possible to repair genetic defects in
embryos, sperm or eggs by genetic modification and, if that can be done safely,
then it could lead to the curing of genetic disorders in subsequent generations
of a family.
While the consultation document emphasises that is not yet possible, and the
existing ban should be retained, it suggests future legislation might be framed
so any ban could be relaxed.
"We invite views as to whether the legislation should include a power for
Parliament to relax this ban through regulations (rather than primary
legislation) if assured of safety and efficacy," it says.
Some fertility centres already screen IVF embryos for serious genetic disorders
using a technique called pre-implantation genetic diagnosis (PGD), so only
those embryos shown to be free of certain condition are implanted into the
However, the advent of PGD allows embryos to be screened for other purposes,
perhaps for even for ensuring that a genetic defect is deliberately screened in
rather than screened out. So a deaf couple for instance could, in theory,
select to have a deaf child.
The Government is asking whether selecting for certain defects - which is
banned - should be allowed. Embryos could also be screened for gender, allowing
couples to select the sex of their baby to "balance" a family of all boys or
"The Government seeks views on sex selection for non-medical reasons. In
particular, should this be banned? Or should people be allowed to use sex
selection techniques for family balancing purposes?" the consultation document
"If so, how many children of one gender should a couple already have before
being allowed to use sex selection techniques to try for a child of the other
gender?" it asks. Under the existing law, no fertility centre in Britain can
offer IVF treatment to a couple unless it takes into account the welfare of the
child born as a result of the treatment, including the need for a father.
The consultation document asks whether it is still valid for the state to
intervene in such a way.
"Some have argued that, as the law does not intervene in the reproductive
choices of people who are able to conceive naturally, it is therefore
discriminatory to intervene where people happen to have fertility problems,"
the document says.
Lord Winston, the fertility expert dismissed the public consultation as a
flawed process yesterday.
"I welcome the reopening of the debate on sex selection but the Government
ought to be highly embarrassed about gauging public opinion through website
consultations when their own research shows this is a deeply flawed process,"
Lord Winston said.
People who want to respond to the consultation have until 25 November. They can

5 key issues that will come under scrutiny
Selection of child's sex
Existing fertility law prohibits the selection of an IVF embryo's gender unless
it is for medical reasons, for instance to avoid the birth of a boy with
haemophilia. A public consultation three years ago found there was strong
opposition to sex selection for non-medical reasons but the Government would
like to revisit the issue and has asked whether it should be allowed.
Altering embryo genes
There is an absolute ban on altering the genetic structure of any cell while it
is still part of a human embryo - which is defined as an egg that has been
fertilised by a sperm. The Government is asking whether research should be
permitted to allow genetic modification for research in order to see whether it
is possible to safely prevent the transmission of harmful genes, or even repair
The role of the father
The 1990 Act specifically states that the welfare of the IVF child should be
taken into account and that this should include "the need of the child for a
father". Some argue this is inappropriate - there is no mention in the Act for
instance of the need for a mother. The Government is asking whether the state
should continue to demand this or whether references to fathers should be
Sperm on the internet
Sperm and eggs donated through a fertility clinic are currently controlled by
existing legislation but sperm sold over the Internet falls outside the current
scope of the law. The Government argues that there are concerns about the
health of such sperm and the legal status of the donors. The Government wants
to bring internet sperm services under the law, either by banning them
altogether or regulating them.
Scientists are working on the possibility of creating gametes - sperm and egg
cells - from other "somatic" cells of the body, such as skin tissue. This would
be of benefit to infertile men and women. But it also raises the possibility of
two women (or men) producing both sperm and eggs to produce their own
biological child. The Government wants to ban the use of artificial gametes.
