Since the birth of Rise In in Ballard in 1978, in vitro
fertilization with embryo r - la~ has became an established method of
treatment for Rain types of infertility that do nok resooTx] to

cycles resulted in clinical pregnancies. In 1986 this figure rose to 16.9

percent of oocybe retrievals ended ~ live birth (Journal of the American
M~di~1 Association, 1988a). Moreover, some women start treatment, but
for a variety of reasons fail to reach the stage of egg retrieval.
Improvements in the surreal rate of IVFET: are probably not the result of
significant changes in the methods of ovarian stimulation or laboratory
procedures. Rather, improvement may be attributed to a *erline in the
average age of women undergoing rVFET, increasing experience of clinician
and laboratory personnel, and more rigorcus-criteria for selection of
patients (Van Blerkom, 1989~.

D~rel~rental failure during cleavage is fairly typical. Even embryos
that do develop to the blasts stage can ac~nta~n a~r~lities in cell
structure or namer that are not coamis~ with Exx;ti~lantation
devel ~ rent (bligh ~ 1 amen, for exaIrple). C~liectively, develc ~ ntal
failure in the early stages of embryonic development appears to be the
normal situation for the human species.
The state of clinical practice of [VFET today is limited by lack of
knowledge of some of the basic reproductive biology involved. The reason
for this is, at least in part, due to the many ethical questions raised by
research in pursuit of the needed information. Difficulties An resolving
these issues have caused the research to be deprived of federal funding.
-This chapter first reviews the uncial and ethical barriers to
progress in research, and then f~s=-~- an the scientific barriers. Brief
note is made some of the ethical issues that are r~;~ by the practice of
in vitro fertilization, and the history of federal involvement in
considerations of human fetal research is described. Some nations have
examined the ethical questions and have issued guidelines or regulations.
These will be described. Finally, the major science barriers that have
slowed progress ~ human and animal practice of rVFET will be noted.
Ethir?~1 art Social Issues
Some of the ethical or social issues that arise from the various
forms of assisted conception are unrelated to decisions akcut the progress
of research. Examples of these are questions about The protection of the
rights of gamete donors, gestational parents, and social parents;
decisions on the fate of oona~i, embryos, arm feted; the oral sums
of human potential; the chip of cry~preserved embryos who parents
have divorce or died; the Confidentiality of sperm donors; arm questions
of the right of a dhilc] born of Icy IS oon~ion to knew his
or her complete parentage. Other fi~t^1 questions revolve art
c::onc~s of the right of an ir~ivi~ to ran uce, the He of gametes
and embryos, and whether infers Chard be Refire as a ~i~.

At ore end of this Putnam of It is the position taken by the
P=nan Catholic azure, him holds that life begins with the Ion of ho

until birth . . . no morel distinction is consi~betw~n zygotes,
pr ~ ryos, embryos or fetuses" (cited in Fertility arxt Sterility,
1988b). Therefore, the absolute sanctity accorded to post-natal human
life begins with the zygote. This concept makes it impossible to
spare embryos or Our them for research purpcees. At the other end of the
spectrum is the position that an embryo is merely biological material like
any other group of living cells. The cg--ial value that might be attached
to that material rats fran the exudations or aspirations of ours.

Department of Health Education and Welfare (DHEW) to advise the Secretary
on matters concerning embryo research, and to review specific research
proposals. Holding this position, the board concluded that research
involving IVFET was acceptable on embryos up to ~4 days after
fertilization. Other constraints on such research included that it should

The EAB met for the first time in 1978. In 1980, the Secretary of
Health and Human Services allowed the EAB charter to expire and, without
explanation, failed to renew it. muss,- federal funding of embryo and
rVFET research was, in effect, prohibited. As a result, embryo research
has relied on private funding from patient care revenues, pharmaceutical
companies, and university budgets. It is estimated that, were the EAB -
active today, it would receive more than 100 grant applications (Office of
Technology Assessment, 1988). In addition, the federal government has
lacked a means for controlling the direction of, or practices used in,
such research. AS was noted in 1979, "Departmental involvement might help
to resolve questions of risk and avoid abuse by encauraging well~;igned
research }A alified scientists. Such involvement might also help to

Other Barriers to Scientific Progress
The research agenda developed by the Institute of Medicine, Board on
Agriculture committee (bloc Chapter 4) identifies many areas ~ which
further research would make major contributions to Em pro cements ~
medically accosted conception in humans and animals. As noted in Chapter
1, improving the application of medically Resisted conception would
benefit society in several ways, including my possible the
privation of sane endanger Species, as well as pravidir~ sane relief
freon infertility arm making proration of =3at arm ILL Ire eoca~ni~al.
ELLIS, however, he }>Ben played by a mar of factors, most of which
stem fry m the g ~ rally controversial rapture of ~ ts surround ~
issues in reproduction, and specific controversies related to elements
important to reproductive research zygotes and embryos.
As a prerequisite to developing recommendations to advance the
science base of medically assisted conception, the committee first
examined the impediments. In addition to the ethical considerations
referred to marker, the following barriers deserve particular emphasis:
1) deficiencies in the scientific base of this area of reproductive
biology; 2) the resources available for research in this area of science;
3) lack of mechanisms for communication within the reproductive research
community among basic scientists, clinicians, and animal husbandry
scientists; 4) four of abuses of reproductive technologies; 5) a relative
lack of sympathy and understanding of the problems being experienced by
infertile couples; 6) lack of a cohesive public interest group favoring
such research, in contrast to well organized opposition; 7) limited health
insurance coverage of IVFET serving=; 8) limited sources of research
materials for experiments relating to human beings and to animals; and 9)
the present dilemma of cur society oonocrnIng how to handle our ethical
sagre~ts.
Almost none of these factors is independent of the others; rather a
causal relationship is often found. Some of the barriers identified may
be amenable to policy Intervention. The following sections briefly review
the impact of the major barriers to progress and how they have come to be
. · .
~ sauce.
Deficiencies in the Science REAP
The papers presented at the committee's workshop and the research
agenda developed frill that workshop (Poe Chapters 2 and 4) indicate
deficiencies in the scientific underpinnings of reproductive biology, and
identify many areas in which further research efforts would make major
oontributions to iIrprove~ts in m—brolly ~.Ccist~ cation. me
deficiencies are on three levels: basic science knot - ge; knowledge
needed to improve the technologies being use for medical ly Waist
Monition, such as cryobiology; and knowledge reed to improve bath
human and animal clinical practice of IVFET. As explained in detail in
—78—
Chapter 2, deficiencies ~ all three levels limit bath the quality and
efficiency of the practice of Ivory.

PI ~
~xi~tely $115 million annually ~ pent on ~ In human
reps ~ Active pr ~ . The major sources of private fulgid (the Ford,
Rockefeller, and A.W. Mellon foundations, and the Population Council) in
1985 together contributed $2.8 million to research related to reproductive
processes. This includes grants to investigate mare and female
infertility, fertilization, zygote transport, reimplantation development
and implantation, and reproductive endocrinology (National Institutes of
Health, 1988~. Federal agencies are the pr ~ ipal support for research.
In 1986 they provided $109 ~ llion for research in reproductive processes
(National Institutes of Health, undated).
the National Institute of Child Health and Human Development (NICHD)
of the National Institutes of Health provides the major portion of federal
support of human reproductive research. Approximately $100 million per
year, one third of the budget of NICHD, is spent in the reproductive
sciences br ~ h of NICHD on contracts and grants to academic centers and
to the NIH centers for reproductive biology. In addition, the
Contraceptive Development Branch, which uses mainly contract meCharjE~5 to
support contraceptive technologies, contributes to basic reproductive
research. Federal funds for research redating to agricultural animal
reproduction are available from the U.S. Department of Agriculture.

m e excitement and stimulation experienced by the individuals
attending this IOM workshop, which encouraged interaction with individuals
from differing backgrounds, underscored how infrequently meaningful
interactions among these communities occur, and how use fur this
interaction could be.
Societal Concerns
m e fear of abuses of reproductive technologies, the seeming lack of
cietal sympathy and understanding of the problems experienced by
infertile couples, and the lack of a cohesive public interest support
group are to scone extent relay pea.

The committee believes that restrictions on the amount of material
available for research ~~=- is slowing the rate of progress in developing a
scientific base for rVFET and the technological advances that would make
it more efficient. These limitations are the result of a concern that
hen material be used with proper respect, art that the use of animals
for research pur~ses be strolled to ensure that they are not ahoy.
—82—
There exist ways, however, of enlarging the amount of avail able research
material while preserving a pro per consideration for thee. issues. Making
available material from organs that have been surgically removed would
increase the supply of human tissue. For instance, when an organ such as
the ovary is removed for medic reasons, it Fight be made available for
harvesting oocytes and eggs.

social As underlie mart of the barriers deco progress In repr~cive

q ing that Congress has established the Bic ~ Scat Ethics Edwards,
and that the executive branch of government is taking steps to reactivate
the Ethics Advisory Board. If these bodies become functional the nation
will have taken steeps to establish entities to handle difficult issues in
reproductive biology.
