Reproductive
Technology
by John M. Haas
Infertility
is a growing problem in the United States. And in true American
fashion, there has been a corresponding growth in a “reproductive
technologies industry” to provide a solution. It is quite
legitimate, indeed praiseworthy, to try to find ways to overcome
infertility. The problem causes great pain and anguish for
many married couples. Since children are a wonderful gift
of marriage, it is a good thing to try to overcome the obstacles
which prevent children from being conceived and born.
In 1987 the Sacred Congregation
for the Doctrine of the Faith issued a document known as Donum
Vitae (“The Gift of Life”), which addressed the morality
of many modern fertility procedures. The document concluded
that some methods are moral, while others—because they do
violence to the dignity of the human person and the institution
of marriage—are immoral. Without questioning the motives of
those using these techniques, Donum Vitae pointed out
that people can do harm to themselves and others even as they
try to do what is good, that is, overcome infertility.
Donum Vitae teaches that
if a given medical intervention helps or assists the marriage
act to achieve pregnancy, it may be considered moral; if the
intervention replaces the marriage act in order to
engender life, it is not moral.
In Vitro Fertilization
One reproductive technology which
the Church has clearly and unequivocally judged to be immoral
is in vitro fertilization or IVF. Unfortunately, most Catholics
are not aware of the Church’s teaching, do not know that IVF
is immoral, and some have used it in attempting to have children.
Children conceived through this procedure are children of
God and are loved by their parents, as they should be. Like
all children, regardless of the circumstances of their conception
and birth, they should be loved, cherished, and cared for.
The immorality of conceiving
children through IVF can be difficult to understand and accept
because the man and woman involved are usually married and
trying to overcome a “medical” problem (infertility) in their
marriage. Why, then, is IVF immoral?
In vitro fertilization brings about
new life in a petri dish. Children engendered through IVF
are sometimes known as “test tube babies.” Several eggs are
aspirated from the woman’s ovary after she has taken a fertility
drug which causes a number of eggs to mature at the same time.
Semen is collected from the man, usually through masturbation.
The egg and sperm are ultimately joined in a glass dish, where
conception takes place and the new life is allowed to develop
for several days. In the simplest case, embryos are then transferred
to the mother’s womb in the hope that one will survive to
term.
Moral Implications
Obviously, IVF eliminates the marriage
act as the means of achieving pregnancy, instead of helping
it achieve this natural end. The new life is not engendered
through an act of love between husband and wife, but by a
laboratory procedure performed by doctors or technicians.
Husband and wife are merely sources for the “raw materials”
of egg and sperm, which are later manipulated by a technician
to cause the sperm to fertilize the egg.
Invariably several embryos are
brought into existence; only those which show the greatest
promise of growing to term are implanted in the womb. The
others are simply discarded or used for experiments. This
is a terrible offense against human life. While a little baby
may ultimately be born because of this procedure, other lives
are usually snuffed out in the process.
IVF is also expensive, costing
at least $10,000 per attempt. Over 90 percent of the embryos
created perish at some point in the process. In a desire to
hold down costs and enhance the odds of success, doctors sometimes
implant five or more embryos in the mother’s womb. This may
result in more babies than a couple wants. In Canada, one
woman gave birth to five children engendered by IVF. She had
wanted only one, so she sued her doctor for “wrongful life,”
demanding that he pay for the cost of raising the four children
she did not want.
To avoid the problems of carrying
and rearing “too many” babies after several have been implanted,
doctors sometimes engage in something euphemistically called
“fetal reduction” or “selective reduction.” Here they monitor
the babies in utero to see if any have defects or are judged
to be less healthy than the others. They eliminate those “less
desirable” babies by filling a syringe with potassium chloride,
maneuvering the needle toward the “selected” baby in the womb
with the aid of ultrasound, and then thrusting the needle
into the baby’s heart. The potassium chloride kills the baby
within minutes, and he or she is expelled as a “miscarriage.”
If it cannot be determined that one baby is less healthy than
the others, some doctors simply eliminate the baby or babies
who are easiest to reach. Again we see the unspeakable diminishing
of the value of human life which can arise from this procedure.
Further Considerations
Not everyone
who has had a child through IVF has used donor eggs or sperm,
collected the sperm through masturbation, or killed “extra”
unwanted babies in the course of the pregnancy. Yet there
is still a moral problem with the procedure itself. Why?
Human beings bear the image and
likeness of God. They are to be reverenced as sacred. Never
are they to be used as a means to an end, not even to satisfy
the deepest desires of an infertile couple. Husbands and wives
“make love,” they do not “make babies.” They give expression
to their love for one another, and a child may or may not
be engendered by that act of love. The marital act is not
a manufacturing process, and children are not products. Like
the Son of God Himself, we are the kind of beings who are
“begotten, not made” and, therefore, of equal status and dignity
with our parents.
In IVF, children are engendered
through a technical process, subjected to “quality control,”
and eliminated if found “defective.” In their very coming
into being, these children are thoroughly subjected to the
arbitrary choices of those bringing them into being. In the
words of Donum Vitae:
The
connection between in vitro fertilization and the voluntary
destruction of human embryos occurs too often. This is significant:
through these procedures, with apparently contrary purposes,
life and death are subjected to the decision of man, who thus
sets himself up as the giver of life and death by decree.
The document speaks of “the right
of every person to be conceived and to be born within marriage
and from marriage.” To be within and from marriage, conception
should occur from the marriage act which by its nature is
ordered toward loving openness to life, not from the manipulations
of technicians.
The dehumanizing aspects of some
of these procedures is evident in the very language associated
with them. There is the “reproductive technology industry.”
Children are called the “products” of conception. Inherent
in IVF is the treatment of children, in their very coming
into being, as less than human beings.
Moral Options
Any number of morally acceptable
interventions may be used to overcome infertility. For example,
surgery can overcome tubal blockages in the male or female
reproductive system which prevent fertilization from taking
place. Fertility drugs may also be used, with the caution
that large multiple pregnancies may put mother and infants
at risk. There are also many ways of tracking natural reproductive
rhythms to enhance the chances for achieving pregnancy. The
Pope Paul VI Institute at Creighton University in Omaha, Nebraska
has been successful in helping couples overcome infertility
using natural methods.
Most theologians consider the procedure
known as LTOT (Lower Tubal Ovum Transfer) to be morally acceptable.
This involves transferring the wife’s egg beyond a blockage
in the fallopian tube so that marital relations can result
in pregnancy. Another method, more morally controversial,
is called GIFT (Gamete Intra-Fallopian Transfer). It involves
obtaining a husband’s sperm following marital relations and
aspirating an egg from the wife’s ovary. Egg and sperm are
placed in a tiny tube separated by an air bubble, and the
contents of the tube are then injected into the wife’s fallopian
tube with the hope that fertilization will occur. Some theologians
consider this to be a replacement of the marital act, and
therefore immoral. Other theologians see it as assisting the
marital act, and therefore permissible. Because the teaching
authorities of the Church—the Pope and bishops—have not made
a judgment about GIFT, Catholic couples are free to choose
it or reject it depending on the guidance of their own conscience.
If the teaching authority of the Church should judge the procedure
to be immoral, however, GIFT should no longer be used.
The Church has great compassion
for those who suffer from infertility. Out of love for all
human life and respect for the integrity of marital relations,
however, the Church teaches that some means of trying to achieve
pregnancy are not licit. Some of these means actually involve
the taking of innocent human life, or treating human life
as a means toward an end or a “manufactured product.” They
do violence to the dignity of the human person.
In America we have a tendency to
think that we can solve all problems with the right “technology.”
But children are not engendered by technology or produced
by an industry. Children should arise from an act of love
between a husband and wife, in cooperation with God. No human
being can “create” the image of God. That is why we say that
human beings “procreate” with God. Engendering children is
a cooperative act among husband, wife, and God Himself. Children,
in the final analysis, should be begotten not made.
