PREAMBLE
The prospect of therapeutically effective fetal tissue transplants
for disorders such as diabetes and Parkinson's disease has raised
new questions in the ethical discussion on fetal research. These
questions are distinct from those addressed in the 1970s that
focused on invasive procedures performed by some researchers on
living, viable fetuses. They are also separate from the questions
that were raised by the development of new techniques for prenatal
diagnosis such as fetoscopy and chorionic villus sampling. Although
the use of transplanted tissue from a fetus after spontaneous
or induced abortion would appear to be analogous to the use of
cadaver tissue and organs, the moral issue for many is the possibility
that the decision to have an abortion will become coupled with
the decision to donate fetal tissue for the transplantation procedure
itself.
The utilization of human fetal tissue for transplantations is,
for the most part, based upon a large body of research data derived
from experimental animal models. At this time, the number of such
transplants performed has been relatively small but the various
applications are promising avenues of clinical investigation for
certain disorders. The demand for fetal tissue transplantation
for neural or pancreatic cell engrafments may be expected to increase
if further clinical studies conclusively show that this procedure
provides long-term reversal of neural or endrocrine deficits.
Prominent among the currently identified ethical concerns is
the potential for fetal transplants to influence a woman's decision
to have an abortion. These concerns are based, at least in part,
on the possibility that some women may wish to become pregnant
for the sole purpose of aborting the fetus and either donating
the tissue to a relative or selling the tissue for financial gain.
Others suggest that a woman who is ambivalent about a decision
to have an abortion might be swayed by arguments about the good
that could be achieved if she opts to terminate the pregnancy.
These concerns demand the prohibition of:
- the donation of fetal tissue to designated recipients;
- the sale of such tissue; and
- the request for consent to use the tissue for transplantation
before a final decision regarding abortion has been made.
The abortion process may also be influenced inappropriately
by the physician. Consequently, measures must be taken to assure
that decisions to donate fetal tissue for transplantation do not
affect either the techniques used to induce the abortion or the
timing of the procedure itself with respect to the gestational
age of the fetus. Also to avoid conflict of interest, physicians
and other health care personnel involved in performing abortions
should not receive any direct or indirect benefit from the research
or transplantation use of tissues derived from the aborted fetus.
The retrieval and preservation of usable tissue cannot become
the primary focus of abortion. Therefore, members of the transplant
team should not influence or participate in the abortion process.
There is a potential commercial gain for those involved in the
retrieval, storage, testing, preparation, and delivery of fetal
tissues. Providing fetal tissue by nonprofit mechanisms designated
to cover costs only would reduce the possibility of direct or
indirect influence on a woman to acquire her consent for donation
of the aborted fetal remains.
RECOMMENDATIONS
The World Medical Association affirms that the use of fetal tissue
for transplantation purposes is still in an experimental stage
and should only be ethically permissible when:
- The World Medical Association Declaration of Helsinki and
the Declaration on Human Organ Transplantation are followed,
as they pertain to the donor and the recipient of the fetal
tissue transplant.
- Fetal tissue is provided in a manner consistent with the
World Medical Association Statement on Live Organ Trade and
that such tissue not be provided in exchange for financial remuneration
above that which is necessary to cover reasonable expenses.
- The recipient of the tissue is not designated by the donor.
- A final decision regarding abortion is made before initiating
discussion of the transplantation use of fetal tissue. Absolute
independence is established and guaranteed between the medical
team performing the abortion and the team using the fetus for
therapeutic purposes.
- Decision concerning the timing of the abortion is based on
the state of health of the mother, and of the fetus. Decisions
regarding the technique used to induce abortion, as well as
the timing of the abortion in relation to the gestational age
of the fetus, are based on concern for the safety of the pregnant
woman.
- Health care personnel involved in the termination of a particular
pregnancy do not participate in or receive any benefit from
the transplantation of tissue from the abortus of the same pregnancy.
- Informed consent on behalf of both the donor and the recipient
is obtained in accordance with applicable law.
