The Medical
Realities
A sound approach to the ethics of abortion must
be grounded in the scientific and medical facts. The facts of prenatal development are
indispensable for determining when human life begins. When those facts are known, it
remains for the ethicist, the physician, the legislator, and society at large to interpret
their moral and legal implications. Many of the questions that arise from the abortion
controversy are directly related to medical practice: under what conditions, if any, is
abortion necessary to save the life of the mother: Under what conditions, if any, would
abortion be indicated on the grounds of mental health? What methods of abortion are used
in America today, and what medical hazards are associated with these methods? These and
other related questions are central to the contemporary abortion debate.
The Facts of Prenatal Development [1]
Any discussion of abortion that ignores the facts of prenatal development in
incomplete. The unborn child, after all, is a
End of Page 21 - Begin Page 22
central figure in the abortion controversy. His or her moral
and legal status depends on a careful examination of the process of prenatal development.
It is most unfortunate that scientific facts known for decades or longer have
been quietly ignored by many proponents of abortion. Arguments that the unborn child is
simply "part of the woman's body," or that human life does not begin at
conception do not accord with the well-established scientific facts. Even medical
authorities personally sympathetic to abortion acknowledge that. An editorial in California
Medicine, the official journal of the California Medical Association, makes this
clear:
The process of eroding the old ethic and substituting the new
has already begun. It may be seen most clearly in changing attitudes toward human
abortion. In defiance of the long held Western ethic of intrinsic and equal value for
every human life regardless of its stage, condition, or status, abortion is becoming
acceptable by society as moral, right, and even necessary. . . . since the old ethic has
not been fully displaced it has been necessary to separate the idea of abortion from the
idea of killing, which continues to be socially abhorrent. The result has been a curious
avoidance of the scientific fact, which everyone really knows, that human life begins at
conception and is continuous whether intra- or extra-uterine until death. The very
considerable semantic gymnastics which are required to rationalize abortion as anything
but taking a human life would be ludicrous if they were not often put forth under socially
impeccable auspices. It is suggested that this schizophrenic sort of subterfuge is
necessary because while a new ethic is being accepted the old one has not yet been
rejected. [2]
The inevitable distortions caused by passion and prejudice
make it all the more imperative to keep the scientific facts clearly in focus.
It is a well-established fact that a genetically distinct human being is
brought into existence at conception. During intercourse, some 300,000,000 sperm are
deposited in the vagina and begin a journey upwards through the uterus and into the
Fallopian tube leading from the uterus toward the ovary. If an ovum has been released from
the ovary, it passes from the ovary down the Fallopian tube towards the uterus. The
survival time of the unfertilized egg is
Page 23
thought to be approximately 24 hours. Both sperm and egg will
die if fertilization does not occur within that time period. The newly fertilized egg,
called a zygote, contains the hereditary characteristics of both mother and father, one
half from each, derived from the DNA material, the genetic thread of life.
The newly fertilized egg contains a staggering amount of genetic information,
sufficient to control the individual's growth and development for an entire lifetime. A
single thread of DNA from a human cell contains information equivalent to a library of one
thousand volumes, or six hundred thousand printed pages with five hundred words on a page.
The genetic information stored in the new individual at conception is the equivalent of
fifty times the amount of information contained in the Encyclopedia Britannica. [3]
There is an important qualitative difference between the fertilized and
unfertilized human ovum. Neither sperm nor egg has any capacity for independent life, and
both will die unless they participate in the fertilization process. Once fertilization has
taken place, the zygote is its own entity, genetically distinct from both mother and
father. The newly conceived individual possesses all the necessary information for a
self-directed development and will proceed to grow in the usual human fashion, given time
and nourishment. It is simply untrue that the unborn child is merely "part of the
mother's body." In addition to being genetically distinct from the time of
conception, the unborn possesses separate circulatory, nervous, and endocrine systems.
Likewise, it is misleading to speak about the newly conceived as "potential"
human life. Prior to conception the sperm and egg represent only the potentiality of a new
human life, but once fertilization has taken place, an actual human life has begun. More
accurately, the newly conceived individual is an actual life with great potential.
After fertilization the zygote divides first into two cells, then four, then
eight, and so on, at a rate of almost one division per day. It is now known that during
this earliest stage of development the mass of cells may divide into identical parts
forming identical twins. Such "twinning" may occur until the fourteenth day,
though it is relatively uncommon, occurring in only one out of about 300 births. During
these first several days it is also possible for twins or triplets
Page 24
to be recombined into a single individual. It thus appears
that during the earliest stages of prenatal development, for at least a small fraction of
zygotes, irreversible individuality may not be present. The moral implications of this
eventuality will be considered later.
After the first six or seven days of cell division, which takes place in the
Fallopian tube, the new human life enters the uterus and implants itself in the uterine
lining. This is often called the "blastocyst" stage. One pole of the growing
sphere of cells, called the trophoblast, penetrates the uterine lining and develops into
the placenta. The other pole develops as the embryonic human being. It is worth noting
here that the placenta is an extension of the child's body, not the mother's. The part of
the developing blastocyst that becomes the placenta produces hormones, which enter the
mother's bloodstream and prevent the onset of menstruation. This hormonal signal sent to
the mother's body from the newly conceived life is essential for its survival, since
otherwise the new life would be sloughed away by the menstrual flow. Even at this early
stage it is the newly conceived individual, rather than the mother, that takes the
initiative in effecting crucial physiological changes. The newly conceived human being is
far from passive in the development process. The mother provides an environment for the
unborn child, but the child's hormonal system has an active influence on changes in that
environment. [4]
After two weeks of development the name of the new human life is changed from
zygote to embryo. Blood cells are formed by 17 days, and a rudimentary heart as early as
18 days. The embryonic heart, beginning as a simple tube, shows irregular pulsations at 24
days and approximately one week later exhibits rhythmic contraction and expansion.
The development of the nervous system also begins at approximately the
eighteenth day. By the twenty-first day the foundations of the child's brain, spinal cord,
nerves, and sense organs are completely formed. Six weeks after conception the nervous
system is so well developed that it controls the movements of the child's muscles, though
the woman may not yet even be aware that she is pregnant.
Page 25
By the end of the sixth week, all the internal
signs of the unborn child are present, though yet in a rudimentary form. The brain is
sending out impulses, which coordinate the functions of the other bodily organs. Reflex
responses are present at 42 days, and brain waves have been noted at 43 days. The blood
vessels leading from the heart are fully deployed and continue to grow in size. The
stomach is producing digestive juices, and the kidneys are beginning to function by
extracting uric acid from the child's blood.
By the end of the seventh week, the child will flex his neck if the mouth and
nose are tickled with a hair. By this time the ears are also formed and may show the
specific features of a family pattern. At about this time the name is changed from embryo
to fetus (Latin, "young one or offspring").[5] By now the fingers and toes are fully
recognizable. Lines in the hands and fingerprints begin to appear at eight weeks and
remain a distinctive characteristic of the individual. Between the ninth and tenth weeks
local reflexes such as swallowing, squinting, and tongue retraction begin to appear. If
the child's forehead is touched, he may turn his head away and pucker up and frown. By now
the child can bend the wrist and elbow independently and has the full use of his arms. By
this time the entire body is sensitive to touch and is also capable of spontaneous
movement. Thumb sucking has been observed by the eleventh week, and x-rays will disclose
clear details of the skeleton.
By the twelfth week, the child is swallowing regularly and can move his thumb
in opposition to his fingers. The child, three and one half inches long by the end of the
twelfth week, will have a complete brain structure, which will of course continue to grow.
At this time, as Arnold Gesell has stated, the unborn child "is a sentient moving
being. We need not pause to speculate as to the nature of his psychic attributes, but we
may assert that the organization of his psychosomatic self is now well under way." [6]
By this time, the child is active and the reflexes are more pronounced.
Muscular response is no longer mechanical and irregular, but now graceful and fluid. This
motion is present prior to "quickening," when the mother first notices the
child's movements, which generally occurs between weeks 12 and 16, although some women
feel very little movement as late as 20 weeks. It should be clearly
Page 26
understood that the time of "quickening," long
considered important in the law, represents a mother's subjective perception, and not an
objective point at which "animation" occurs or the first "signs of
life" appear. As Dr. Albert W. Liley, a widely recognized authority in fetal
medicine, has stated:
Historically, "quickening" was supposed to
delineate the time when the fetus became an independent human being possessed of a soul.
Now, however, we know that while he may have been too small to make his motions felt, the
unborn baby is active and independent long before his mother feels him. Quickening is a
maternal sensitivity and depends on the mother's own fat, the position of the placenta and
the size and strength of the unborn child. Quickening is hardly an objective basis for
making a decision about the existence or the value of the life of the unborn child. [7]
The child grows very rapidly between the twelfth
and sixteenth weeks. He has grown to eight or ten inches in height, and his weight
increases sixfold. At some point between the sixteenth and twentieth week it becomes
possible to hear the child's heartbeat with a simple stethoscope, as well as by the
refined EKG apparatus. By the end of the fifth month, the child weighs approximately one
pound and will be about 12 inches long. Fine baby hair has begun to grow on his head and a
fringe of eyelashes is beginning to appear. The skeleton is hardening, and the mother can
feel the child's head, arms, and legs. After the twentieth week it is customary to speak
of a premature delivery rather than of a spontaneous abortion.
By the twenty-eighth week, the child weighs slightly over two pounds, and
some definitions of "viability" are fixed at this point. This, however, is only
an approximation. According to Dr. Andre Hellegers of Georgetown University, 10 percent of
children born between 20 and 24 weeks gestation will survive.[8] The development of an
artificial placenta would push the date of viability back into the earliest stages of
gestation. Modern techniques of intensive therapy are able to save premature babies that
would have been considered non-viable only a few years ago.
The progress of prenatal medicine has made it increasingly clear that the
unborn child possesses a distinct individuality. As Dr.
Page 27
Arnold Gesell has noted:
Our own repeated observation of a large group of fetal
infants. . . left us with no doubt that psychologically they were individuals. Just as no
two looked alike, so no two behaved precisely alike. . . . These were genuine individual
differences, already prophetic of the diversity which distinguishes the human family. [9]
The unborn child is no mere "mass of
tissue," but a distinctly individualized human being with a characteristic pattern of
behavior. Medical advances have also eliminated the artificial distinction between
prenatal and postnatal human life. Dr. H.M. Liley explains:
In assessing fetal health, the doctor now watches changes in
maternal function very carefully, for he has learned that it is actually the mother who is
a passive carrier, while the fetus is very largely in charge of the pregnancy. [10]
Pregnancy involves the medical care of two patients, not one.
The unborn child is not a passive partner, but rather in many ways controls the dynamics
of the pregnancy. This new perception of the unborn child has led to the development of a
whole new medical specialty called perinatology, which cares for its patients from
conception to about one year of postnatal existence. For the modern physician, human life
begins at conception, and medical care and observation must start at the earliest period
of life.
Techniques of Abortion
There are four common methods of abortion:[11] dilation and curettage ("D&C");
intrauterine injection of hypertonic saline solution ("salting out");
hysterotomy; and prostaglandin infusion. None of these techniques is without risk to the
mother.
Dilation and curettage is the technique most commonly used in first trimester
abortions. The cervical muscle ring is first paralyzed and then stretched open. A curette,
a loop-shaped steel knife, is then inserted into the uterus. The surgeon then scrapes the
uterine wall, dismembering the developing child and scraping the placenta
Page 28
from its attachment on the wall of the uterus. Bleeding is
usually profuse. A common first-trimester alternative is a vacuum aspiration or suction
abortion. The principle is the same as the D & C. After the cervix has been stretched,
a powerful suction tube is inserted into the uterus. The body of the developing child and
the placenta are sucked into a jar, where smaller parts of the child's body are often
still recognizable.
Even these early, first trimester abortions are not without significant hazards to
the woman's health. In a study of 1182 legal abortions at an English teaching hospital,
nearly 17 percent of the patients lost more than 500 milliliters of blood and 9.5 percent
required transfusions. There were also cases of cervical laceration and perforated
uteruses.[12] Another study concluded that
perforation of the uterus is an almost inevitable complication of induced abortion by
vacuum aspiration or during any other form of dilation and curettage.[13] Even so-called "menstrual
extractions" or "lunch hour" abortions performed by vacuum aspiration
within one to three weeks after failure to menstruate have been attended with
complications: the woman's not being pregnant, the implanted ovum's being missed by the
suction curette, and uterine perforation. [14]
Second trimester abortions are often by salt poisoning. A long needle is
inserted through the abdomen and a solution of concentrated salt is injected directly into
the amniotic sac. The child breathes in the salt solution and is poisoned by it. The
concentrated saline solution burns off the outer layer of the baby's skin and brain
hemorrhages are frequent. It takes about one hour for the child to slowly die by this
method. Approximately one day later the woman goes into labor and delivers a dead baby.
The salt poisoning technique is common in the United States in spite of its
well-documented hazards. It was used by the Japanese after World War II but later
abandoned because of maternal morbidity and mortality.[15] Maternal deaths have been reported from
accidental injection of the saline solution into the circulatory system, from acute kidney
failure, from seepage through uterine puncture wounds into the abdominal cavity, and from
infections.[16] Other documented complications
of saline abortions include fevers, cervical lacerations, serious disruptions of the blood
coagulation
Page 29
mechanism, and hemorrhages. [17]
If the pregnancy is too advanced for the D & C or salting out procedures,
a hysterotomy abortion may be performed. The techniques for a hysterotomy abortion are
similar to those for a caesarean section, except that the incisions made in the abdomen
and uterus are smaller. Having been removed from the uterus, the child is laid aside to
die from neglect. This procedure is even more hazardous for the woman than the salting out
procedure. The potential for accidental rupture during subsequent pregnancies is also
appreciable, especially during labor. [18]
More recently the drugs prostaglandin E2 and prostaglandin F2a
have been widely investigated as abortifacients. These drugs artificially induce
labor and may be administered orally, intravenously, by vaginal suppositories, or by
direct injection into the amniotic sac. Although usually too small to survive, the child
is frequently born alive. Thus far prostaglandin abortions have produced a number of
significant complications. In one study 30 percent of the women undergoing prostaglandin
abortions experienced vomiting.[19] Other
problems encountered with prostaglandin abortions include incomplete evacuation of the
uterus, hemorrhages, infections, and cervical lacerations. [20]
The findings of the English study cited earlier accept the overall medical
risks of induced abortions:
The morbidity and fatal potential of criminal abortion is
accepted widely, while at the same time the public is misled into believing that legal
abortion is a trivial incident even a lunch-hour procedure, which can be used as a mere
extension of contraceptive practice. There has been almost a conspiracy of silence in
declaring its risks. Unfortunately, because of the emotional reactions to legal abortion,
well-documented evidence from countries with a vast experience of it receives little
attention in either the medical or lay press. This is medically indefensible when patients
suffer as a result. [21]
The well-documented medical evidence shows that induced
abortion is far from a simple and hazard-free operation. There has been a dangerous
silence concerning the risks of abortion not only in England but also in America. It is
high time this silence be broken.

Indications for Abortion
Later in this volume we will discuss the problems of rape and potential birth
defects as possible indications for induced abortion. Here the discussion will focus on
psychiatric problems and specific physical conditions during pregnancy that might be
thought to constitute a threat to the physical health of the mother.
During the last two decades there has been a marked increase in the number of
abortions performed on psychiatric grounds. Prior to the 1973 Supreme Court abortion
decisions 90 percent of abortions in Oregon were performed on such grounds. It is likely,
however, that many abortions aimed at preventing "grave impairments to mental
health" were in fact subterfuges for other social problems and personal
inconveniences. Competent psychiatric opinion is agreed that there are no known
psychiatric diseases that can be cured by abortion; further, there are none that can be
predictably improved by abortion.[22] Nor are
there any clear-cut psychiatric indications for abortion. According to the standard
psychiatric textbook of Noyes and Kolb, experience shows that pregnancy and childbirth do
not adversely influence the course of schizophrenias, manic-depressive illnesses, or the
majority of psychoneuroses.[23] With
appropriate treatment, depressive psychoses carry a good prognosis whether or not the
pregnancy is interrupted.[24]
Threats of suicide are frequently presented as psychiatric indications for
abortion. But as Sloane has pointed out,
Although the risk of suicide is perhaps the most frequently
used psychiatric indication for therapeutic abortion, there is almost unanimous agreement
that it is extremely rare. Hook in her follow-up study of nearly 300 women could not find
a single one who had either committed or attempted suicide during the pregnancy. [25]
The suicide rate among pregnant women in fact appears to be
one-sixth the rate among non-pregnant women of the same age. [26]
The experience of one British medical social worker indicates that easy
accession to abortion on psychological grounds may in fact be a grave disservice to the
woman:
....the woman's feeling that she cannot tolerate bringing a
Page 31
child into the world may be a symptom of a situation such as
an inability to cope with married life, and by making abortion too readily available we do
little but relieve the patient's immediate suffering for a short time and thus do her no
real service, producing in her a sense of guilt which she can redress only by becoming
pregnant again as quickly as possible. . . . When talking to the parents of these unborn
children one must at all times be aware that what may at first seem to be an
uncompromising attitude may swing around to a complete reversal of the original rejection.
[27]
Experience shows that maternal attitudes can change, and
unwanted conceptions very often produce wanted children. Psychiatric problems,
then, rarely if ever justify abortion. On the contrary, such problems call for the proper
mental health care and emotional and spiritual support needed by pregnant women in
difficult circumstances.
But are there physical conditions that might constitute valid indications for
abortion? According to one recent authority, there are in general "very few absolute
contraindications to pregnancy and even these are gradually disappearing with modern
medical advances."[28] As a result of
these advances, it is now extremely rare for any pregnancy to be so hazardous to a woman
as to necessitate abortion. Pregnancy, labor, and delivery, if properly managed, have no
deleterious effects upon a pregnant woman suffering from tuberculosis.[29] Organic heart disease occurs in only one or
two percent of pregnant women, and only about one in ten of these is serious enough even
to consider an induced abortion.[30] Pregnant
women suffering from diabetes or kidney disorders can, with very few exceptions, be
brought safely to term.[31] A few diseases,
such as rheumatoid arthritis, are actually improved during pregnancy.[32] Given this favorable outlook for pregnant
women with medical complications, it is not surprising that a study reported to the World
Health Organization found that, even in the permissive contemporary abortion climate,
patients who had abortions on medical grounds formed only four to six percent of most
reported series.[33] It is likely that, had
optimal medical care been available, the latter figures would have been even lower.
Page 32
Admittedly, there are those tragic situations,
fortunately rare, where induced abortion may be necessary to save the life of the mother.
Two such circumstances involve an ectopic (tubal) pregnancy and a cancerous uterus.
Without intervention in such cases, both mother and child may perish. The motive for
surgical intervention is not to end the child's life but to save the life that has some
reasonable chance of survival, i.e., the mother's. The death of the child is a secondary
result of the lifesaving intervention. Given present medical technology, the unborn in
such circumstances have little or no chance of survival. But with new medical advances,
which will hasten viability, such tragic dilemmas should be even less frequent, if not
eliminated.
Complications of Induced Abortion
The most serious complication of induced abortion is, of course, the death of
the mother. Proponents of abortion cite data from Eastern European countries and the
United States to the effect that abortion is "x-times as safe as childbirth."
The limitations of such an argument have been pointed out by other writers.[34] For example, maternal deaths related to
abortion may simply go unreported or, if reported, may be attributed to other causes. That
would artificially deflate the actual maternal death rate. Moreover, isolating attention
on maternal mortality rates overlooks two other very important considerations, namely, the
death of the unborn child, and nonfatal injuries to the woman. Two individuals, not one,
are at risk in an abortion, the child being subject to direct assault. And furthermore,
evidence from many countries around the world indicates that women in America are not
being fully informed about the long-term hazards of what has become our nation's most
common surgical procedure.
As we have already noted, a study of 1182 abortions performed in an English
teaching hospital showed that nearly 17 percent of the patients lost more than 500
milliliters of blood and 9.5 percent required blood transfusions. Other women suffered
cervical lacerations, perforated uteruses, peritonitis, and septicaemia. [35]
Studies performed in Greece indicate a clear connection between
Page 33
induced abortion and subsequent stillbirths, premature
births, and sterility. One study was made of 13,242 women who were admitted for delivery
over a two-year period at hospitals in Athens. Of the 8,312 women whose pregnancy was not
the first, 29 percent admitted to one or more induced abortions. Among that group, the
average number of abortions was two. The percentage of premature births and stillbirths
among the women with previous abortions, spontaneous or induced, doubled that of the
control group.[36] Another study conducted in
Athens carefully matched the women surveyed with a control group of similar age,
socioeconomic background, and previous childbearing history. The researchers found that
the relative risk of subsequent sterility among women with at least one induced abortion
and no spontaneous abortions was 3.4 times that among women without any induced or
spontaneous abortions. The study concluded that in Greece about 45 percent of the cases of
secondary infertility may be attributed to previous induced abortions. [37]
A study conducted in the Hebrew University-Hadassah Medical School in
Jerusalem examined the effects of induced abortion on the outcome of subsequent
pregnancies. Of 11,057 pregnant women interviewed in West Jerusalem, the 752 women who
disclosed one or more induced abortions in the past were more likely to report bleeding in
each of the first three months of their current pregnancies. They were also less likely to
have a normal delivery, and more of them needed a manual removal of the placenta or other
obstetrical intervention during the final stage of labor. Increases were found in major
and minor birth defects. There was a significant increase in the incidence of low
birthweights. [38]
Physicians from Eastern European nations such as Yugoslavia, Czechoslovakia,
and Hungary, where abortion has been legal for many years, are now calling attention to
the significant complications arising from permissive abortion policies. According to J.
Jurukovski and L. Sukarov, in Hungary the rate of premature births is 11 to 12 percent
overall, rising to 15 percent in towns. "There seems little doubt that there is a
true relationship between the high incidence of induced abortion and prematurity,"
according to these researchers.[39] They also
conclude that the total incidence of complications
Page 34
following induced abortions is considerably higher than
usually reported, probably on the order of ten percent.[40] Alfred Kotasek, a Czechoslovakian researcher
studying the effects of induced abortion in his own country, found that acute inflammatory
complications occurred in about five percent of the cases. Other complications, including
chronic inflammation of the genital organs, sterility, and tubal pregnancies, were
registered in about 20 to 30 percent of all women having induced abortions. Also observed
was a high incidence of cervical incompetence, increasing the risks of miscarriage during
future pregnancies.[41] These disturbing
findings by Eastern European investigators are reflected in the conclusions drawn by
Yugoslavian physicians after a study of over 80,000 abortions performed in that country:
In the light of our long experience . . . we must conclude
that even in cases of legal abortions, despite improvements in abortion techniques, the
woman suffers both physically and emotionally. This is the overriding medical and ethical
consideration which for us completely resolves the choice between legal abortion and
contraception." [42]
Thus far, these somber warnings have gone largely unheeded in
the United States. Neither the mass media nor the American medical establishment has
properly publicized the documented hazards of abortion. As a result, growing numbers of
American women now having abortions, many of them unmarried teenagers, may soon awaken to
the tragic discovery that they have impaired their health and their childbearing
capacities in the process.
