Eugenic abortion: an ethical critique Malcolm N. Beck, MD, CM, FRCPC In 1967 the CMA officially approved abortions by physicians when there was "a substantial chance that the child would be born with grave mental or physical disability".' The stimulus for that revolution in the ethics of medical practice was the newly demonstrated causal association between maternal German measles in early pregnancy and severe physical and mental defects in the newborn.' I recall that there was surprisingly little debate about the resolution in the medical press or among members of the medical profession. Most of us thought that such a procedure would rarely be used. The policy still stands,2 but new technologic advances in ultrasonography, intrauterine techniques, karyotyping, biochemical analysis of amniotic fluid and molecular genetics have resulted in eugenic abortions becoming a regular occurrence in medical practice in Canada. Since 1967 few articles have addressed the rationale and indications for eugenic abortion, and even fewer have questioned whether eugenic abortion should be performed at all. The medical literature has betrayed a widespread, usually unstated assumption by the profession that fetal life should be terminated whenever a serious congenital abnormality is strongly suspected. It is now possible to diagnose relatively reliably 200 or more handicapping disorders. In Canada a surge in the use of such prenatal diagnostic techniques occurred in 1976 after the publication of three reports of international collaborative studies3-5 and one from the Medical Research Council of Canada.6 As early as 1983 Allanson and associates7 reported that 50% of older pregnant women in the Vancouver area "took advantage of the availability of amniocentesis". The indications now accepted for the prenatal investigation and diagnosis of genetic disorders have been established by the Society of Obstetricians and Gynaecologists of Canada;8 the most common indication by far is high maternal age, usually defined as over 35 years, at the expected date of delivery.

Physicians are not only accepting and sometimes promoting such investigative procedures but also are being increasingly pressed by older mothers and their partners to do them, mostly because of the fear of having a retarded child. The 16th postmenstrual week is the preferred time for amniocentesis. Since it takes 2 to 3 weeks for the laboratory analysis and reporting, the minimum time for the termination of fetal life is the 18th gestational week. Several authors have reported a mean gestational age of 20 weeks.6'9"'0 The issues raised by eugenic abortion should be distinguished carefully from those raised by the continuing debate on abortion as a matter of reproductive choice, determined by the "mother's own priorities and aspirations", the terminology used by the Supreme Court of Canada in the Morgentaler decision." Eugenic abortion deals with neither the pathos of an unplanned, unwelcome or forced pregnancy nor the personal matter of freedom of choice about what happens to one's body. Instead, it involves a deliberate, systematic search for those who may be unfit in mind or body, the primary intent being to terminate fetal life if such is found. If the fetus is thought to be "normal" the pregnancy is allowed to continue. Therefore, I prefer the more descriptive term "selective feticide", following Roberts and collaborators,'2 over the more common terms such as eugenic abortion, selective abortion and genetic abortion. My preference is supported by an awareness of the infrequently used, yet widely accepted, practice of selectively terminating the life of an "abnormal" twin in utero by exsanguination or injection of potassium chloride or a bolus of sterile air directly into its heart or umbilical vein and allowing the "normal" twin to develop to term. The dead twin is not "aborted" but, rather, is delivered at term as a fetus papyraceus.'3-'5 Selective feticide should not be equated with the reduction of multiple pregnancies associated with assisted ovulation and fertilization.

tive is to create a maternal environment in which one or more of the fetuses can survive to viability and normality - a goal compatible with the traditional scope of medicine. 16,'7 Physicians should be concerned about the continuing welfare of their patients and the attitude of society toward them. Mentally handicapped people are not able to speak well for themselves; therefore, we who serve them must speak on their behalf, because it is unlikely that others will. Selective feticide is fraught with technical problems and clinical complications and may have severe psychologic effects on the mothers. It has ethical implications for physicians and some broader social implications. In addition, it may adversely affect the social identity of the medical profession.

Adverse effects of amniocentesis on the fetus Amniocentesis is not harmless. Early reports were divided on whether it caused fetal loss, but other, larger studies have demonstrated that uncomplicated amniocentesis in the second trimester has caused an increase in the mortality rate of healthy fetuses of 0.5% to 1.0% because of an increased rate of spontaneous abortion and a small but significant increase in the perinatal mortality rate.6,8- 10.1217-21 Also, after amniocentesis an increase of 0.4% above the expected rate of prenatal hemorrhage from placenta previa and abruptio placentae has been reported,'8 as has a threefold increase in the incidence of breathing problems in the normal newborn and of orthopedic problems, especially club foot and congenital dislocation of the hip.20,22 In a Canadian study Finnegan and colleagues23 found "needle marks" 6 months after birth on 6 of 91 infants whose mothers had undergone amniocentesis. Although the marks were only cosmetically important, they reviewed reports of single or rare instances of needle injury, such as exsanguination, cardiac puncture, puncture of the gut, ocular trauma, neurologic damage to a limb and gangrene of a

limb. False-positive and false-negative laboratory results do occur.24 The error rate of 0.3% in cytogenetic diagnosis reported in larger series is very low but of critical significance when the termination of life is involved.'0 Procedural mistakes by physicians, nurses, laboratory technicians and clerical staff occur despite the utmost care.'0 Furthermore, the procedures are not very effective in decreasing the rate of mental retardation. For example, the screening of mothers over 35 years of age prevents the birth of only 25% of the children expected to be born with Down's syndrome.25 The human cost for this supposed gain is very high: the number of cases of 182

handicap prevented by these prenatal procedures is almost identical to the number of "normal" children sacrificed.26 27 Primum non nocere.

Adverse effects of selective feticide on the mother The degree of psychiatric illness caused by induced abortion of unwanted pregnancies may still be debatable.28 29 However, selective feticide and the related experiences create unusually high levels of stress for the mother30-32 and negatively affect the father33 and the siblings of the aborted fetus.34 The mothers are usually mature in their thoughtfulness and sensitivity, and their pregnancies are often planned, wanted and sometimes treasured events. For 4 months they have anticipated the healthy outcome of their pregnancy. Shortly after amniocentesis they experience quickening, with its consequent enhancement of maternal attachment and an increased awareness of the fetus as having a separate existence.3536 The interval of 2 to 4 weeks between amniocentesis and receipt of the laboratory results causes much anxiety and even denial of the pregnancy by the parents;37 this anxiety is not always relieved by good genetic counselling, which may even increase the mother's anxiety.38 When unwanted results are received the parents must make very difficult personal decisions based on concepts couched in terms that are foreign and often dreadful to them. The termination of a pregnancy through amnioinfusion techniques subjects the mother to distressing labour, which is often poorly attended by the medical and nursing caregivers.37 The stress is much less on the mother and the nurses if the abortion is done through dilatation and evacuation, which in skilled hands is the preferred procedure up to 20 weeks' gestation; however, this procedure is much more distasteful and stressful to the physician.3940 With the use of infusion techniques the dead fetus is easily recognizable as a tiny human being and may be seen by the mother after delivery. Physical complications after a second-trimester abortion for any reason are common4' and more frequent than would be acceptable in regular elective surgery. Castodot42 reported that in abortion after 16 weeks' gestation the rate of hemorrhage is over 10%, endometritis 10%, cervical laceration 3% and retained products of conception 32% to 46%. Grimes and Schulz,43 who reported the results of a collaborative study of 84 000 late induced abortions, found that abortion at 20 to 21 weeks resulted in a 12.4% risk of hemorrhage and a 7.7% risk of cervical laceration. The psychologic complications after delivery are also severe. Mothers who have undergone eugenic

abortion and have previously lost a child because of stillbirth or neonatal death have reported that the level of bereavement is equal; too often the intensity of the grief is not eased by the usually healing process of mourning.44,45 Normal grieving is confounded by the mother's mixed feelings of guilt and grief, her sense of relief about and responsibility for the abortion and the lack of awareness of the depth of her loss by the people close to her. There is no baby, no name, no photograph, no funeral, no grave.46 These negative psychologic consequences are not helped by the negative attitude of physicians to eugenic abortion, which is shown by the low rate of their attendance during the delivery39 and the lack of follow-up care given by physicians and public health nurses as compared with that given the same mothers after previous stillbirths or neonatal deaths.46 47 The few reports of follow-up of eugenic abortion have suggested that the rate of psychiatric complications is high.44-49 Lloyd and Laurence46 followed up 53 cases and, although the study was inadequately controlled, found that 78% of the women had acute grief reactions similar to those expected in any situation of major bereavement; 46% continued to suffer from clinically significant anxiety or depressive states up to 6 months after the abortion, and 10% required psychiatric treatment.

Ethical issues The central ethical issue in selective abortion is whether physicians should become involved in purely eugenic procedures that involve the termination of a human life. A cogent understanding of the proclivity of mankind to evil50 and the actions of the very sophisticated medical profession in Germany in the 1930s5-153 suggest that we should be very leery of such an involvement. The fears are not allayed by reports of the use of selective abortion techniques in India, administered on the basis of sex (Winnipeg Free Press, Aug. 28, 1982, and Times of India [Bombay ed], Oct. 17, 1985),54,55 or by evidence of a widespread acceptance of this practice among medical geneticists in the United States and Canada56 and the students of a supposedly conservative rural US college.57 Eugenic abortion is most often done at a gestational age that nearly approaches the age of fetal viability, even with good sequencing of procedures and reports. The dramatic advances in neonatology have resulted in the age of viability being changed to 24 weeks or even lower.58'59 At its 1988 meeting the CMA General Council accepted 20 weeks as the age of viability.2 However, in Britain the termination over a period of 6 months of 26 fetuses after 24 weeks' gestation was reported.606' Also, it has been

argued that the statutory age of viability not be lowered from 28 weeks because to do so might encourage legal infringement on the practice of late abortion of defective fetuses.31'60'62'63 What is technologically possible is not always right. Our ability to use these new techniques confronts us with the modem moral predicament posed by the Durants:64 Have we given ourselves more freedom than our intelligence can digest?

Broader social implications Vigorous public education efforts by the helping professions and voluntary organizations such as the Association for Community Living, formerly the Canadian Association for the Mentally Retarded, have done much to reduce the stigma borne by handicapped people. However, we should be concerned lest these gains be lost when most expectant mothers over 35 years of age and their husbands decide to have prenatal diagnostic studies done with the intent of terminating the life of their unborn child if a mental or physical defect is suspected. Such a reversal in public attitude could lessen the resolve of governments to fund adequate medical and other service programs for handicapped people and could diminish the impetus for public institutions to fund research into the disorders underlying mental and physical disability.65 It has been regularly argued in the medical literature that the economic burden of the lifelong care of retarded people provides adequate justification for genetic abortions.66-69 The economic load is real, but this argument is based on sociopolitical, not medical, premises (Audrey D. Cole: personal communication, 1985). Paradoxically, although the practice of eugenic abortion continues to grow, there is an increasing awareness that the fetus possesses an identity independent from its mother.70 This is prompted by increased public awareness of the success of prenatal fetal therapy71-73 and the procession of legal suits on behalf of children for "prematernal liability", "wrongful birth" and "wrongful life". Although a consensus on such suits has not been reached in the courts of the Commonwealth countries or the United States, physicians should be aware that a child can now sue his or her parents for giving them birth and win.74-76 New techniques, such as chorionic villus sampling, may lower the fetal age at which life can be terminated after prenatal laboratory diagnosis, but the risks of chorionic villus sampling are not yet confirmed as being acceptably low. Studies have shown the rate of fetal loss to be 0.7% to 2.7% higher than that associated with amniocentesis.71-8' When this is added to the increase of 0.5% to 1.0% in the CAN MED ASSOC J 1990; 143 (3)

and laboratories, in the silence of the womb and in the sterility of the operating theatres. In so doing the profession veils the awful reality of the means to attain such nonmedical, sociopolitical goals from public view and awareness. Physicians should not assume this death-dealing role. This great and historical, learned profession should not have thus allowed itself to become either the unwitting agent of public policy or the automatic servant of popular demand.
