U.S. Public Policy and the Biotechnologies
That Touch the Beginnings of Human Life:
Draft Recommendations
Over the past twenty months, the Council has devoted much time
and energy to examining the current governance of the uses of biotechnologies
that touch the beginnings of human life, practices arising at the
intersection of assisted reproduction, genetic screening, and human
embryo research. The Council has heard from various experts and
stakeholders, engaged its own comprehensive diagnosis of current
regulatory mechanisms and institutions, outlined the key findings
emerging from that diagnosis, and surveyed various general and specific
policy options. The Council now understands a great deal about the
current regulatory landscape and has identified concerns that suggest
the need for improved monitoring, oversight, and, perhaps, new forms
of governmental regulation. Yet we are very far from being able
to offer clear and well considered recommendations regarding major
institutional reforms. We do not know the precise costs and benefits
of overhauling existing regulatory institutions and practices or
of creating new regulatory authorities. We do not even know enough
about the incidence and severity of some of the possible risks and
harms we have identified as causes of concern to judge whether they
are serious enough to justify changing the present arrangements.
We do not accurately know, for example, how the technologies and
practices at the heart of our inquiry affect the health of those
whose lives are touched by them — most notably, the children
conceived with their aid. Similarly, we do not know how widely preimplantation
genetic diagnosis or preconception (and preimplantation) sex selection
will be practiced, and for which purposes. Without the answers to
such questions, it would be premature at best to recommend dramatic
legal or institutional changes. Further research and inquiry, and
additional consultations with all the relevant actors, are clearly
needed.
Yet even as such inquiry and consultation proceeds, the Council
believes that some improvements can and should now be implemented
to address some of the concerns identified as a result of our present
inquiry. There are a number of measures, described in Sections I
and II below, that the Council believes the federal government and
the various relevant professional societies should adopt immediately.
Most of these suggestions are aimed precisely at the remaining empirical
questions described above. These include a call for comprehensive
information gathering, data collection, monitoring, and reporting
of the uses and effects of these technologies. They also address
the need for improving informed decision-making, consumer protection,
and enforcement of existing guidelines for practitioners of assisted
reproductive technologies (ART). In addition, in Section III, we
identify for Council discussion several aspects of the dignity of
human procreation that may warrant interim prudent legislative action,
especially in light of rapidly arriving innovations that signal
new departures in human reproduction. Familiar disquiet regarding
human cloning or commerce in human embryos and gametes is augmented
by recent reports of fusion of male and female embryos into one
chimerical organism, and of the derivation of gametes from embryonic
stem cells (in principle enabling embryos to become biological parents).
Accordingly, while policymakers monitor and gather information and
while deliberation continues in search of better and more permanent
monitoring and oversight arrangements, it may be necessary and desirable
to enact interim prophylactic limitations. Such limitations would
prevent individuals, acting on their own, from introducing major
innovations into human procreation in the absence of full public
discussion and deliberation about their ethical and social implications
and consequences.
The recommendations we offer here are consensus recommendations
of the Council. Though we differ about certain fundamental ethical
questions in this field, and especially about the moral status of
the human embryo, we have nevertheless been able to agree on several
policy suggestions that we believe should command not only the respect
but also the assent of most people of common sense, good will, and
a public-spirited concern for human freedom and dignity. We have
sought to frame these recommendations with sufficient specificity
that they might be adopted by the relevant target audiences.
I. Federal Studies, Data Collection, Reporting, and Monitoring
regarding the Uses and Effects of These Technologies
A. Undertake a federally funded longitudinal study
on the health and development impacts of ARTs on children born with
their aid. A most important unanswered question before
the Council concerns the precise effects of ART and adjunct technologies
on the health and normal development of children born with their
aid. There have been a few studies, mostly undertaken abroad, reaching
variable and sometimes contrary results. An effort has been undertaken,
by the Genetics and Public Policy Center in collaboration with the
American Academy of Pediatrics and the American Society for Reproductive
Medicine, to review all of the existing literature on this question.
This is a laudable start, capable of identifying harmful health
and development outcomes that should be monitored in the future.
The Council strongly believes that what is needed now is a prospective
longitudinal study that is national, comprehensive, and federally
funded, and which looks at both the short-term and long-term effects
of these technologies and practices on the health of children produced
with their assistance, including any cognitive, developmental, or
physical impairments. An ideal vehicle for this study is the National
Children's Study now being planned by a consortium of federal agencies
led by the National Institute of Child Health and Human Development
(NICHD), which, beginning in 2005, will track the health and development
of 100,000 children across the United States from before birth until
age 21.
B. Undertake federally funded studies on the impacts
of ARTs on women. Another area where better information
would be helpful regards the health and well-being of women who
use ARTs. One or more studies, either in conjunction with or separate
from the above-mentioned longitudinal study should be conducted
to discover the effects, if any, of the use of ARTs on women’s
health, including any short-term or long-term hormonal, emotional,
or physical impairments.
C. Undertake federally funded comprehensive studies
on the uses and effects of reproductive genetic technologies.
As noted above, assisted reproduction and genomic knowledge are
increasingly converging. Practices such as preimplantation genetic
diagnosis and gamete sorting represent the first fusion of these
disciplines. Before these practices become routine, it is necessary
for policymakers and the public to understand their present and
projected uses and effects. To this end, there should be a federally
funded comprehensive study, undertaken with the full participation
of the ART industry, on how and to what extent such practices are
currently and may soon be employed, and their health effects on
children born with their aid. Mechanisms need to be developed for
ongoing monitoring of the outcomes of these practices and others
to which they may lead.
D. Strengthen and augment the Fertility Clinic Success
Rate and Certification Act. As currently written,
the FCSRCA is aimed at providing consumers with key information
about the pregnancy and live-birth success rates of assisted reproduction
clinics in the United States. We believe that the Act should be
augmented and strengthened, both to improve this original function
of consumer protection and to enable the federal government (through
the already existing Centers for Disease Control ART surveillance
program) to gather information and to monitor the development, uses,
and effects of all technologies and practices that touch the beginnings
of human life. Toward these ends, the Act should be improved and
strengthened in the following ways.
1. Enhance Reporting Requirements.
(a) Efficacy: Provide more user-friendly reporting of data,
including adding “patients” as an additional unit
of measure. Currently, data are reported only in terms of
“cycles” of treatment (beginning when a woman starts
ovarian stimulation or monitoring), rather than in terms of individual
patients treated. Thus, it is impossible to know how many individuals
undergo assisted reproduction procedures in a given year, how
many patients achieve success in the first (or second or third)
cycle, how many women fail to conceive, and the like. Presenting
results in terms of numbers of individuals would be more meaningful
to prospective patients and would yield more precise information
for policymakers.
(b) Risks and Side Effects: Require reporting of all adverse
health effects. There is today no mechanism for reporting
adverse health effects of assisted reproductive technologies,
either for the adult patients or for the children produced. Such
adverse effects are of paramount concern for prospective patients,
policymakers, and the public at large. ART clinics should be asked
to provide data on the incidence of adverse effects on women undergoing
treatment, as well as on the health and development of children
born using ART, at least through the first year of life.
(c) Costs: Require the reporting of the average costs of the
procedures and successful pregnancy. There is currently no
comprehensive source of information regarding these costs. Not
surprisingly, prospective patients are keenly interested in this
information. Moreover, policymakers interested in questions regarding
equality of access and related matters would greatly benefit from
such information. It would shed light on the incentives currently
at work that may induce patients and clinicians to engage in risky
behavior, such as the transfer of multiple embryos in each cycle,
in an effort to reduce costs.
(d) Untransferred Embryos: Require reporting of creation,
use, and disposition of embryos. There is at present no means
of reporting or monitoring the creation, use, and disposition
of embryos produced in the context of assisted reproduction. By
requiring such reporting, the federal government would signal
a measure of respect for nascent human life and would allow prospective
patients, policy makers, and the public to better understand the
actual practice of assisted reproduction. Specifically, it would
yield information regarding the number of embryos typically required
to achieve a successful pregnancy, the ultimate disposition of
untransferred embryos, and present and projected numbers of embryos
in cryopreservation, as well as the rules and practices regarding
the fate of the stored embryos.
(e) Innovative Techniques: Include information on novel and
experimental procedures. A key area of concern for the Council
is the ease and speed with which experimental technologies and
procedures (such as intracytoplasmic sperm injection [ICSI] or
preimplantation genetic diagnosis [PGD]) move into clinical practice,
even in the absence of careful clinical trials regarding the efficacy
and long-term consequences. It would be useful for consumers and
policymakers to understand more fully how each clinic manages
this process and what safeguards are in place. Such information
would include human subjects protections, the extent to which
technologies are tested in animals, the standards that must be
satisfied before a given procedure is deemed fit for clinical
use, and the measures taken to evaluate safety and efficacy.
(f) Adjunct Technologies: Require more specific reporting
on the frequency of, and reasons for, uses of specialized techniques
(such as ICSI), genetic diagnosis, sperm sorting for sex-selection,
etc. Little is understood about the frequency and uses of
the various adjunct technologies and practices complementing standard
IVF. While the current version of the Act provides some raw data
on the number of cycles in which certain techniques are used,
this information is inadequate for policymakers and the public
to understand fully the contours of present practice. For example,
the present system of reporting sheds no light on why patients
chose ICSI as their preferred method of fertilization. The CDC
reported that in 2000, ICSI was used in 46 percent of all IVF
cycles, yet in nearly 40 percent of these instances the prospective
patients did not suffer from male factor infertility. Also, because
results are reported in terms of cycles rather than patients (as
discussed above), it is impossible to know how many individuals
used ICSI in 2000. Other techniques, particularly those fusing
reproductive technology and genomic knowledge, are not reported
at all under the present version of the Act. For example, there
is no requirement to report the number of cycles using PGD, much
less the reasons for using PGD. For example, how many patients
using PGD are infertile? How many have family histories of genetic
disorders? What sort of screening is being done? For aneuploidy
and single-gene mutations? For donor siblings? For non-medical
traits? There is also no reporting of any practices in which sex
selection occurs, and the reasons for undertaking them. Consumer
protection and public policy would be enhanced if this information
were included. Consumers would benefit from knowing how much experience
a given clinic has in performing such procedures. Policymakers
and the public would benefit from knowing how, why, and to what
extent genomic knowledge is being used to enhance control over
procreation.
2. Enhance Patient Protections.
(a) Improved Measures of Reporting: De-emphasize per cycle
“success rates” as chief benchmark. By narrowly
focusing on pregnancy and birth rates per cycle, the Act may unintentionally
be creating incentives for clinicians and patients to adopt practices
that carry extra risks to health and safety. For example, it might
encourage the transfer of an increased number of embryos, leading
to more multiple gestations that threaten both mother and children,
or it might encourage additional use of ICSI to increase the success
rate, even in the absence of male-factor infertility. Also, the
present emphasis on a clinic’s success rate might induce
clinicians to reject patients whose chance of pregnancy is low.
1 Finally, success rates are
highly manipulable. For example, clinicians can reclassify unsuccessful
cycles in an effort to improve their overall statistics. For example,
such clinics might classify their most difficult cases as “research”
rather than as cycles of treatment that must be reported to the
CDC.
(b) Informed decision-making: Provide model decision-making
form. The present Act would be greatly improved by providing
for the promulgation of an easy-to-read model consent form that
includes information on the possible health risks to mother and
child, the novelty of the various procedures used, the number
of procedures performed to date, the outcomes, and the various
safeguards in place to ensure that such procedures are safe and
effective.
3. Improve Implementation.
(a) Enforcement: Provide stronger penalties to enhance compliance.
Under the Act as currently written the only penalty for noncompliance
is publication of the names of non-reporting clinics. This is
insufficient, given the importance of clinic compliance to ART
customers and the greater public. The penalties should reflect
the magnitude of harms to be avoided. We leave to legislators
the question of what precisely these should be.
(b) ?Funding: Increase funding for CDC’s ART surveillance
project. CDC’s budget should be augmented sufficiently to
enable it to undertake the additional measures suggested above.
We leave to legislators the question of how much additional funding
would be required.
II. Increased Oversight by Professional Societies and Industry
Professional oversight has traditionally been the principal mechanism
of regulation for the practice of medicine. While there is a well
developed body of professional guidelines and standards for the
clinical practice of assisted reproduction, the Council has identified
the following substantive areas that require attention and improvement:
A. Improve informed decision-making.
Clinicians and their professional societies should make efforts
to improve the current system of informed decision-making to conform
to the concerns and suggestions described above. ASRM and SART (Society
for Assisted Reproductive Technology) should pay attention not only
to helping devise an improved and standardized consent form, but
also to recommending procedures to their members for discussing
it properly with patients and securing their meaningful consent.
For this purpose, they should consider making training sessions
on this subject a requirement of membership.
B. Treat children-to-be as patients.
ART clinicians should take measures to ensure the health and safety
of all participants in the ART process, including the children who
are born as a result. To this end, ART clinicians should collaborate
with pediatricians in making decisions that might affect the health
and safety of these children. Moreover, they should not view their
responsibility as ending once a pregnancy has been initiated. Clinicians
and professional societies should also cooperate fully and vigorously
with any efforts (such as the studies described in part I above)
to study the effects of ART and related practices on the health
and development of such children. As a substantive matter, clinicians
and professional societies should take concrete steps to reduce
the incidence of multiple embryo transfers and resulting multiple
births.
C. Improve enforcement of existing guidelines. There
are today a host of meaningful guidelines in place for clinicians
and practitioners engaged in ART. However, the relevant professional
societies need to take stronger steps to ensure that these guidelines
are followed. For example, one such society “actively discourages”
the use of PGD for sex selection for non-medical purpose, yet several
prominent members of the society openly advertise the practice.
Professional societies must clarify the contours of appropriate
conduct and adopt reasonable mechanisms of enforcement.
D. Improve procedures for movement of experimental
procedures into practice. Professional societies and
clinicians should develop a more systematic mechanism for reviewing
experimental procedures before they become part of standard clinical
practice. Such a system might include requirements for animal studies,
IRB oversight, and formal discussion of the significance and results
of novel procedures.
E. Create and enforce minimum, uniform standards for
human subjects protection. At present there is no
systematic, mandatory mechanism for protecting human subjects who
are engaged in experimental ART protocols not affiliated with institutions
receiving federal funds. This problem is compounded by the fact
that there is not a clear distinction between research and innovative
clinical practice in the context of ART. Investigational interventions
that could affect the health and well-being of a future child should
be subjected to at least as much ethical scrutiny and regulatory
oversight as investigational interventions affecting humans after
birth. A higher degree of scrutiny and oversight is justified in
this context, because those affected by the interventions cannot
protect their interests and prospective parents may have interests
that conflict with those of the future child. Clinicians and their
professional societies should adopt measures (such as IRB-like oversight)
to provide safeguards to protect the health and well-being of human
subjects.
F. Develop self-imposed ethical boundaries. Clinicians
and professional societies would be well advised to establish for
themselves clear boundaries defining what is and what is not ethically
appropriate conduct, in the context of both research and clinical
practice. Recent events have shown that without such guidance rogue
clinicians and scientists may engage in practices that will, fairly
or unfairly, bring opprobrium on the discipline as a whole. Practices
such as the fusion of male and female embryos, use of gametes harvested
from fetuses (or produced from stem cells) to create embryos, and
transfer of embryos to non-human uteri for purposes of research
fall squarely into this category. The relevant professional societies
should preemptively take a firm stand against such practices and
back it up with meaningful enforcement.
III. Possible Targeted Measures to Defend the Dignity of
Human Procreation
Several particular practices and techniques (some present, some
likely forthcoming) that touch the beginnings of human life raise
new and distinctive challenges to the special character and dignity
of human procreation. For that reason they require special attention,
not only from professional societies but also from the people’s
representatives. Especially because technological innovations are
coming quickly and because there are today no other institutions
capable of setting appropriate limits, we believe the Congress should
consider some targeted measures that might give expression to and
provide protection for the dignity of human procreation, by limiting
the practice of a number of carefully defined activities. These
measures would remain operative at least until policy makers and
the public can discuss the possible impact and human significance
of these new possibilities and deliberate about how they should
be governed or regulated.
A concern for the integrity and dignity of human procreation might
give rise to a fairly wide range of specific provisions, and the
Congress should consider these in their full array. But the concerns
we have taken up in this report, and which emerge from our findings,
suggest to us a few that are especially crucial, and also especially
likely to command fairly broad assent. They may be usefully grouped
around the following four principles and desiderata:
1. Respect for the humanity of human procreation, preserving
a clear boundary between the human and the non-human (or, between
the human and the animal).
2. Respect for women and human pregnancy, protecting
them against certain exploitative and degrading practices.
3. Respect for children born with assisted reproductive
technologies, securing for them the same rights and human attachments
naturally available to children conceived in vivo.
4. Respect for early stages of nascent human life, setting
some agreed upon boundaries on why embryos may be made and how
they may be used and treated.
The following suggestions indicate the kinds of specific measures
that could give concrete expression to these goals and that might
serve as safe interim boundaries, as public deliberation tries to
catch up with rapidly changing technologies.
For instance, in an effort to guard the humanity of human
procreation, Congress might consider a ban (or moratorium) on the
production of human-animal chimeras, produced either by combining
a human gamete with a gamete from any non-human species or by combining
blastomeres from human and non-human embryos to produce a hybrid
human-animal embryo. Legislators might also proscribe the transfer,
for any purpose, of any human embryo into the body of any member
of a non-human species.
To guard the dignity of women and of human pregnancy, legislators
might institute measures to carefully limit the purposes for which
a pregnancy may be initiated artificially. Congress might, for instance,
prohibit the initiation of a human pregnancy (using embryos produced
ex vivo) for purposes of research, for purposes of securing fetal
tissues or organs for transplant, or for any purpose other than
to attempt to produce a live-born child. It might also consider
restrictions on so-called “surrogate pregnancy,” at
least for pay.
To guarantee that all children conceived through assisted reproduction
techniques receive a full and equal share in our common human origins,
legislators might act to make certain that no child conceived by
means of artificial reproductive technologies be denied two (adult,
not fetal or embryonic) human biological parents. This, for instance,
might lead to a prohibition on attempts to conceive a child using
gametes from more than two or less than two human parents, or by
any means other than the union of egg and sperm obtained directly
from such parents. It might also lead to specific prohibitions on
creating a human embryo from the fusion of blastomeres from two
or more other embryos, or by fertilization using gametes obtained
from a human fetus or derived from human embryonic stem cells.
In addition, some measures may be taken to show a decent respect
for the early stages of nascent human life, and therefore set some
general boundaries on how human embryos may be used and treated.
This subject can of course arouse great controversy, but we believe
some measures may be agreeable to all parties to the significant
ongoing dispute over the moral status of the embryo, whether as
modest steps toward the protection of nascent life, or as demonstrations
of a limited but nonetheless genuine respect for the human embryo.
These may include a prohibition on the use in research, or the preservation
for the purpose of conducting research, of any human embryo past
the tenth day of development (not counting any time during which
it is stored in a frozen state); and a prohibition on the buying
and selling of any human organism, at any stage of development.
They may also include a moratorium on creating human embryos solely
for the purpose of research.
Moreover, these concerns, combined with a certain ambiguity in
the patent laws, also suggest the need for a provision instructing
the United States Patent and Trademark Office not to issue patents
on claims directed to or encompassing a human organism at any stage
of development; and amending Title 35, United States Code, section
271(g) (which extends patent protections to products resulting from
a patented process) to exclude any product which is a human organism
at any stage of development. Such a law should, however, be quite
careful to clarify that human genes, human stem cell lines, and
processes that result in human organisms will still be eligible
for patents.
Of course, these are by no means the only possible legislative
measures Congress might take to limit practices that put at risk
the dignity of human procreation. We believe, however, that some
provisions along these lines are at present among the most needful
and most likely to win agreement.

Endnotes
1. There are, of course,
defensible reasons to reject such patients, and it is arguably unethical
to encourage hopes in couples whose chances of pregnancy are extremely
low, or to take their money for a service that is unlikely to do
them any good.
