Abortion is the termination of a
pregnancy associated with the death and expulsion of the
embryo or
fetus from the womb. In medicine, all terminations of pregnancy not resulting in live
birth are defined as abortions. In common parlance, the terms
miscarriage or stillbirth are applied to spontaneous (non-induced) abortions. The ethics and morality of induced abortion has become the subject of an intense debate, especially in the
United States. This article focuses on induced abortions.
Abortion definitions
- Spontaneous abortion: An abortion due to accidental trauma or natural causes. Also known as a stillbirth or miscarriage.
- Induced abortion: Deliberate (human induced) abortion. Induced abortions are subcatagorized into therapeutic abortion and elective abortion.
:
- Therapeutic abortion: An abortion requested because the pregnancy poses health risk to the pregnant woman (gravida).
:
- Elective abortion: An abortion requested for any other reason by the gravida.
Reasons for induced abortions
Women have many reasons to seek an abortion. Some use it as a form of birth control, others seek an abortion because they are victims of rape and still others because of their physical health. According to the
Alan Guttmacher Institute, there were 1.31 million abortions in the US in 2000, and cases of rape or incest accounted for 1.0% of abortions in 2000. Women from 27 nations reported the following reasons for seeking an induced abortion:
- 25.5% – Want to postpone childbearing
- 21.3% – Cannot afford a baby
- 14.1% – Has relationship problem or partner does not want pregnancy
- 12.2% – Too young; parent(s) or other(s) object to pregnancy
- 10.8% – Having a child will disrupt education or job
- 7.9% – Want no (more) children
- 3.3% – Risk to fetal health
- 2.8% – Risk to maternal health
- 2.1% – Rape, incest, other
In many areas of the world, especially the developing nations or where induced abortions are illegal, many women choose or are forced to perform abortions on themselves. These
self-induced abortions are commonly
unsafe abortions as described by the
World Health Organization. Furthermore, some abortions are induced because of societal or legal pressure, such as under China's
one-child policy. These policies and societal pressures can lead to
sex-selective abortion and infanticide, which is illegal in most countries, but difficult to stop.
Methods of inducing abortion
Depending on the gestational age of the developing embryo or fetus, different methods of abortion can be preformed to remove embryo or fetus from the womb.
Chemical abortion
Main article: Chemical abortion
Chemical abortion comprimising 10% of all abortions in the United States and Europe, is a method used to induce abortion by ingesting drugs, usually during the first nine weeks of pregnancy. The
Morning-after pill must be taken very soon after the sperm and ovum fuse, forming a zygote, aborting any further development of the embryo by preventing from implanting in the uterus. Further into the pregnancy chemical abortion is accomplished by administering either
methotrexate or
mifepristone (RU-486) followed by administration of
misoprostol. Approximately eight percent of these abortions require surgical follow-up, usually by vacuum aspiration (See below). Methotrexate may also treat undiagnosed or concomitant tubal pregnancies.
Surgical abortion
In the first fifteen weeks,
suction-aspiration or vacuum abortion are the most common methods, replacing the more risky
dilation and curettage (D & C).
Manual vacuum aspiration, or MVA abortion, consists of removing the
fetus or
embryo by suction using a manual
syringe, while the
Electric vacuum aspiration or EVA abortion method uses suction produced by an electric
pump to remove the
fetus or
embryo. From the fifteenth week up until around the eighteenth week, a surgical
dilation and evacuation (D & E) is used. D & E consists of opening the
cervix of the
uterus and emptying it using surgical instruments and suction.
Dilation and suction curettage consists of emptying the
uterus by suction using a different apparatus.
Curettage refers to the cleaning of the walls of the
uterus with a
curette.
Dilation and curettage (D & C) is a standard gynaecological procedure performed for a variety of reasons, such as examination.
As the
fetus grows, other techniques must be used to induce abortion in the third
trimester. Premature delivery of the human fetus can be induced with
prostaglandin; this can be coupled with injecting the
amniotic fluid with caustic solutions containing
saline or
urea. Very late abortions can be brought about by the controversial
intact dilation and extraction (intact D & X) which requires the surgical decompression of the fetus's head before evacuation and is controversially termed "
partial-birth abortion". A
hysterotomy abortion, similar to a caesarian section but ending with a dead fetus, can also be used at late stages of pregnancy.
Other means of abortion
Certain herbs are considered by some to be effective
abortifacients. Using herbs in this way can cause serious side effects, including multiple organ failure and other serious injury, and are not recommended by physicians. Many herbal recipes were compiled and published in medieval times under the name of
Peter of Spain.
Physical trauma to a pregnant woman's womb can cause an abortion. The severity of the impact required to cause an abortion carries high risk of injury to the pregnant woman, without necessarily inducing a
miscarriage. Both accidental and deliberate abortions of this kind carry criminal liability in many countries.
Health risks
Even in regulated legal clinics, there is a small risk of serious complications from the most common surgical abortion procedures. These risks include perforated
uterus,
septic shock,
sterility, and
death. The exact risk and type of complications depend on the abortion method as well as the clinical and hygienic conditions. The risks of abortion should be counterpointed to the risks of childbirth.
Studies have found that in developed countries where abortion is legal, the risk of serious physical complications of an abortion is less than 1%. In countries where abortion is illegal, this percentage is much higher, although the exact figure is unknown. This is likely due to the inherently dangerous nature of unregulated illegal surgery by doctors of dubious skill.
Use of "traditional medicine" methods (overdoses of various drugs, inserting various objects into uterus) for abortions is also dangerous. Serious complications from abortions done outside of professional clinics may include infections, bleeding, and in many cases lead to death.
Physical health
:A recent study indicated a higher chance of premature birth after an aborted pregnancy. Women with a previous induced abortion had a 50% increased risk of a very pre-term delivery (less than 33 weeks), and the risk of an extremely premature baby (less than 28 weeks) was 70% higher. Abortion is likely a factor for premature birth, associated with premature rupture of membranes, incorrect position of the fetus on the placenta and spontaneous early labor. Earlier studies had shown an increased risk of preterm birth associated with abortion, but had failed to establish a conclusive link.
:The
abortion-breast cancer (ABC) hypothesis posits an association between having an abortion and a higher risk of developing
breast cancer. The proposed mechanism is based on the increased
estrogen levels found during early
pregnancy, which initiate
cellular differentiation (growth) in the
breast in preparation for lactation. The ABC
hypothesis states that if the pregnancy is aborted before full differentiation in the third
trimester, then more "vulnerable" undifferentiated cells would be left than prior to the pregnancy, resulting in an elevated risk of
breast cancer. The majority of interview-based studies have indicated a link, some are statistically significant, but there is debate as to their reliability.
:The most recent
meta-analysis of 53
epidemiological studies published by Dr. Beral et al. in
The Lancet in
March 2004 found no ABC link; those findings have been disputed by
Dr. Brind, a leading scientific advocate of the ABC hypothesis. Nevertheless, gaps and inconsistencies remain in the research as the "ABC link" continues to be a politicized issue.
- A specific complication that can arise, especially with repeated abortions by a dilatation and curettage, is the development of Asherman syndrome.
Mental health
Research has been carried on the question of whether abortion is associated with increased risk of
clinical depression, but the results are mixed.
- According to one study of 1,884 women conducted by the National Longitudinal Survey of Youth, women whose first pregnancy ended in abortion are 65% more likely to be diagnosed with clinical depression around eight years later.
- Another study of 2,525 women revealed that women who had an abortion were more likely to report depression or lower satisfaction with their lives. However, they also often reported rape, childhood physical and sexual abuse, and violent partners. After controlling for the history of abuse, partner characteristics, and background variables, abortion was not related to poorer mental health.
- A study in the Medical Science Monitor stated that, "Consistent with previous research, the data here suggest abortion can increase stress and decrease coping abilities, particularly for those women who have a history of adverse childhood events and prior traumata." In the study, 65% of post-abortive American women and 13.1% of Russian women experienced multiple symptoms of increased arousal, re-experiencing, and avoidance associated with posttraumatic stress disorder (PTSD). According to the study, 14.3% of American and 0.9 % of Russian women met the full diagnostic criteria for PTSD.
Debate on abortion laws
Abortion has been a controversial subject throughout history due to the
moral and ethical issues that surround it.
Both
Human rights and
constitutional rights are major issues. The complex issue usually focuses on the legal status of induced abortions. Advocates for making or keeping induced abortion illegal are usually termed
Pro-Life. Advocates for making or keeping abortion legal are usually termed
Pro-Choice.
Current status of abortion law
Historically, some cultures have offered legal protection to unborn human offspring. Abortion has been banned and otherwise limited. Almost two thirds of the world's women currently reside in countries where abortion may be obtained for certain reasons. Abortion laws vary widely by nation, with some countries allowing nearly total liberalization (examples including the United States, China and Russia), and others banning abortion under any circumstances. In the United States, the
Supreme Court has held that state laws restricting abortion contradict an implied constitutional right of privacy (see
Abortion in the United States), while the German Supreme Court
struck down state laws legalizing abortion, holding that they contradict the
constitution's human rights guarantees. There are also countries that do not have any laws restricting abortion, such as
Canada (see
Abortion in Canada).
The ongoing debate
Pro-choice stance
The pro-choice stance usually appeals to several ideals, such as the rights of
privacy and bodily integrity, which state that any person should be free to choose what to do with his or her body without government interference. Further arguments include issues of gender equality. and
reproductive rights. Pro-choice advocates also often argue that abortion needs to be widely available because some women become pregnant due to
rape or
incest or have dangerous pregnancies such as
ectopic pregnancies or conditions such as
Eisenmenger's Syndrome that threaten the health of a woman and/or the fetus. Finally, many pro-choice advocates argue that abortions should be legal to prevent
self-induced abortions. Pro-choice groups include the
National Organization for Women,
American Civil Liberties Union and
Planned Parenthood.
Pro-life stance
The pro-life stance usually appeals to several ideals, such as universal
human rights and the protection of the innocent. Pro-life advocates hold that the fetus is both an innocent
person and a human being. Further arguments hold that since the fetus is an innocent unborn human being, the circumstances of conception are irrellivant. Pro-life advocates usually promote solving unwanted pregnancy through
adoption, instead of abortion. Pro-life advocates often promote the
culture of life, which holds the
right to life as the most fundamental of all rights. In doing so, the pro-life stance is part of a more general advocacy against euthanasia, unjust war and most capital punishment. Pro-life groups include the Catholic Church,
Feminists for life and Carenet.
Common Ground
One issue where both the pro-choice and pro-life camps find common ground is the pressure felt by pregnant women. The shared belief is that many pregnant women feel pressure that makes abortion seem to be the only reasonable option, and not a true choice. Advocate groups on both sides have worked on some combination of improving information pregnancy prevention, improving access to
birth control, and funding and improving
adoption services.
Abortion as a political issue
Abortion has been a bitterly-fought
political issue, particularly in the
United States. The controversy in the U.S. started in 1973 with the case of
Roe vs. Wade, when the Supreme Court ruled abortion to be a constitutionally protected right. Specifically, it ruled that states could not forbid a woman to terminate her pregnancy in the first three months (the first trimester) of her pregnancy. The United States Supreme Court is largely considered the gatekeeper of abortion rights in the United States, and as a result, the possibility of the balance of the Court shifting towards a more conservative body became an issue in the 2004 US Presidential Election.
In many other countries, abortion is less of a political issue. For a long time, it has not been a mainstream political issue in the
United Kingdom. In the lead up to the
2005 General Election,
Michael Howard, the leader of the
Conservatives, stated that he, personally, might support a reduction in the limit from 24 weeks to 20 weeks, but the issue was not included in the party's manifesto for the election.
Other views
Early feminists took the view that abortion was a horrible tragedy, a disastrous crime, and a male-supported instrument to further power over women. Since then, the feminist movement has split into
Pro-life feminists, while the majority of feminist groups are pro-choice.
Further complicating the debate is the issue of paternal rights, involving what rights and responsibilities the father has regarding the unborn offspring in question.
