Abortion is defined as the termination of pregnancy (mammals)|pregnancy by the removal or expulsion from the uterus of a fetus or embryo prior to fetal viability|viability . An abortion can occur spontaneously, in which case it is usually called a miscarriage , or it can be purposely Abortion#Induction methods|induced . The term abortion most commonly refers to the induced abortion of a human pregnancy.
Abortion, when induced in the developed country|developed world in accordance with abortion law|local law , is #Safety|among the safest procedures in medicine .

Reasons for procuring induced abortions are typically characterized as either therapeutic or elective. An abortion is medically referred to as a therapeutic abortion when it is performed to save the life of the pregnant woman; prevent harm to the woman's physical or mental health; terminate a pregnancy where indications are that the child will have a significantly increased chance of premature morbidity or mortality or be otherwise disabled; or to selective reduction|selectively reduce the number of fetuses to lessen health risks associated with multiple birth|multiple pregnancy .cite web|last=Roche|first=Natalie E.|date=28 September 2004 |title=Therapeutic Abortion |publisher= eMedicine |archiveurl= http://web.archive.org/web/20041214092044/ http://www.emedicine.com/MED/topic3311.htm |url= http://emedicine.medscape.com/article/252560-overview |archivedate=14 December 2004 |accessdate=19 June 2011 An abortion is referred to as an elective or voluntary abortion when it is performed at the request of the woman for non-medical reasons.

Induction methods
Medical
Main|Medical abortion Medical abortions are those induced by abortifacient pharmaceuticals. Medical abortion became an alternative method of abortion with the availability of prostaglandin prostaglandin analogue|analog s in the early 1970s and the antiprogestin|antiprogestogen mifepristone in the 1980s.cite journal|author=Kulier R, Kapp N, Gülmezoglu AM, Hofmeyr GJ, Cheng L, Campana A|title=Medical methods for first trimester abortion|journal=Cochrane Database Syst Rev|year=2011|issue=11|page=CD002855|doi=10.1002/14651858.CD002855.pub4|pmid=22071804|volume=11cite book|author=Creinin MD, Gemzell-Danielsson K|year=2009|chapter=Medical abortion in early pregnancy|editor=Paul M, Lichtenberg ES, Borgatta L, Grimes DA, Stubblefield PG, Creinin MD (eds.)|title=Management of unintended and abnormal pregnancy: comprehensive abortion care|location=Oxford|publisher=Wiley-Blackwell|pages=111–134|isbn=1405176962cite book|author=Kapp N, von Hertzen H|year=2009|chapter=Medical methods to induce abortion in the second trimester|editor=Paul M, Lichtenberg ES, Borgatta L, Grimes DA, Stubblefield PG, Creinin MD (eds.)|title=Management of unintended and abnormal pregnancy: comprehensive abortion care|location=Oxford|publisher=Wiley-Blackwell|pages=178–192|isbn=1405176962
The most common early first-trimester medical abortion regimens use mifepristone in combination with a prostaglandin analog ( misoprostol or gemeprost ) up to 9 weeks gestational age, methotrexate in combination with a prostaglandin analog up to 7 weeks gestation, or a prostaglandin analog alone. Mifepristone–misoprostol combination regimens work faster and are more effective at later gestational ages than methotrexate–misoprostol combination regimens, and combination regimens are more effective than misoprostol alone.
In very early abortions, up to 7 weeks gestation, medical abortion using a mifepristone–misoprostol combination regimen is considered to be more effective than surgical abortion (vacuum aspiration), especially when clinical practice does not include detailed inspection of aspirated tissue.cite book|author=WHO Department of Reproductive Health and Research|date=23 November 2006|title=Frequently asked clinical questions about medical abortion|location=Geneva|publisher=World Health Organization|isbn=9241594845|url= http://whqlibdoc.who.int/publications/2006/9241594845_eng.pdf|accessdate=2011-11-22 Early medical abortion regimens using 200& nbsp;mg of mifepristone, followed 24–48 hours later by 800 mcg of buccal or vaginal misoprostol are 98% effective up to 9 weeks gestational age.cite journal|author=Fjerstad M, Sivin I, Lichtenberg ES, Trussell J, Cleland K, Cullins V|date=September 2009|title=Effectiveness of medical abortion with mifepristone and buccal misoprostol through 59 gestational days |journal=Contraception |volume=80 |issue=3 |pages=282–286 |doi=10.1016/j.contraception.2009.03.010 |pmid=19698822
The regimen (200 mg of mifepristone, followed 24–48 hours later by 800 mcg of vaginal misoprostol) previously used by Planned Parenthood clinics in the United States from 2001 to March 2006 was 98.5% effective through 63 days gestation—with an ongoing pregnancy rate of about 0.5%, and an additional 1% of patients having uterine evacuation for various reasons, including problematic bleeding, persistent gestational sac, clinician judgment or patient request.
The regimen (200 mg of mifepristone, followed 24–48 hours later by 800 mcg of wikt:buccal|buccal misoprostol) currently used by Planned Parenthood clinics in the United States since April 2006 is 98.3% effective through 59 days gestation.

Medical abortion regimens using mifepristone in combination with a prostaglandin analog are the most common methods used for second-trimester abortions in Canada, most of Europe, China and India, in contrast to the United States where 96% of second-trimester abortions are performed surgically by dilation and evacuation.cite book|author=Hammond C, Chasen ST|year=2009|chapter=Dilation and evacuation|editor=Paul M, Lichtenberg ES, Borgatta L, Grimes DA, Stubblefield PG, Creinin MD (eds.)|title=Management of unintended and abnormal pregnancy: comprehensive abortion care|location=Oxford|publisher=Wiley-Blackwell|pages=178–192|isbn=1405176962
Surgical
In the first 15 weeks, suction-aspiration abortion|suction-aspiration or vacuum abortion is the most common surgical method.cite web|author=Healthwise |url= http://www.webmd.com/hw/womens_conditions/tw1078.asp#tw1112 |title=Manual and vacuum aspiration for abortion |year=2004 |publisher= WebMD |accessdate=2008-12-05| archiveurl= http://web.archive.org/web/20081028141321/ http://www.webmd.com/hw/womens_conditions/tw1078.asp| archivedate= 28 October 2008 | deadurl= noManual vacuum aspiration (MVA) abortion consists of removing the fetus or embryo , placenta and membranes by suction using a manual syringe, while electric vacuum aspiration (EVA) abortion uses an electric pump. These techniques are comparable, and differ in the mechanism used to apply suction, how early in pregnancy they can be used, and whether cervical dilation is necessary. MVA, also known as "mini-suction" and " menstrual extraction ", can be used in very early pregnancy, and does not require cervical dilation. Dilation and curettage (D& C), the second most common method of surgical abortion, is a standard gynecological procedure performed for a variety of reasons, including examination of the uterine lining for possible malignancy, investigation of abnormal bleeding, and abortion. Curettage refers to cleaning the walls of the uterus with a curette . The World Health Organization recommends this procedure, also called sharp curettage, only when MVA is unavailable.Cite book|author= World Health Organization |chapter=Dilatation and curettage |chapterurl= http://www.who.int/reproductive-health/impac/Procedures/Dilatetion_P61_P63.html |title=Managing Complications in Pregnancy and Childbirth: A Guide for Midwives and Doctors |publisher= World Health Organization |location=Geneva |year=2003 |pages= |isbn=978-92-4-154587-7 |oclc=181845530 |accessdate=2008-12-05
From the 15th week until approximately the 26th, other techniques must be used. Dilation and evacuation (D& E) consists of opening the cervix of the uterus and emptying it using surgical instruments and suction. Premature labor and delivery can be induced with prostaglandin ; this can be coupled with injecting the amniotic sac|amniotic fluid with hypertonic solutions containing saline (medicine)|saline or urea . After the 16th week of gestation, abortions can also be induced by intact dilation and extraction (IDX) (also called intrauterine cranial decompression), which requires surgical decompression of the fetus's head before evacuation. IDX is sometimes called " partial-birth abortion ," which has been Partial-Birth Abortion Ban Act|federally banned in the United States.
In the third trimester of pregnancy, abortion may be performed by IDX as described above, induction of labor, or by hysterotomy. Hysterotomy abortion is a procedure similar to a caesarean section and is performed under general anesthesia . It requires a smaller incision than a caesarean section and is used during later stages of pregnancy.cite encyclopedia |last=McGee |first=Glenn |authorlink=Glenn McGee |coauthors= Jon F.

Unsafe abortion
Main|Unsafe abortionUnsafe abortions are a major cause of injury and death among women worldwide. Although data are imprecise, it is estimated that approximately 20 million unsafe abortions are performed annually, with 97% taking place in developing country|developing countries . Unsafe abortion is believed to result in approximately 68,000 deathsCite journal|last1=Haddad |first1=LB. |last2=Nour |first2=NM. |title=Unsafe abortion: unnecessary maternal mortality |journal=Rev Obstet Gynecol |volume=2 |issue=2 |pages=122–6|year=2009 |doi=|pmid=19609407 |pmc=2709326 and millions of injuries annually. Groups such as the World Health Organization have advocated a public-health approach to addressing unsafe abortion, emphasizing the legalization of abortion, the training of medical personnel, and ensuring access to reproductive-health services.cite journal |author=Berer M |title=Making abortions safe: a matter of good public health policy and practice |journal=Bull.

Women seeking to terminate their pregnancies sometimes resort to unsafe methods, particularly when access to legal abortion is restricted. They may attempt to self-induced abortion|self-abort or rely on another person who does not have proper medical training or access to proper facilities. This has a tendency to lead to severe complications, such as incomplete abortion, sepsis , hemorrhage, and damage to internal organs.Cite journal |last1=Okonofua |first1=F. |title=Abortion and maternal mortality in the developing world |journal=Journal of Obstetrics and Gynaecology Canada| volume=28 |issue=11 |pages=974–979 |year=2006 |pmid=17169222| url= http://www.jogc.org/abstracts/full/200611_WomensHealth_1.pdf |format=PDF

It has been estimated that the incidence of unsafe abortion could be reduced by as much as 73% without any change in abortion laws if modern family planning and maternal health services were readily available globally.Singh, Susheela et al. http://www.guttmacher.org/pubs/AddingItUp2009.pdf Adding it Up: The Costs and Benefits of Investing in Family Planning and Newborn Health (New York: Guttmacher Institute and United Nations Population Fund 2009): "If women’s contraceptive needs were addressed (and assuming no changes in abortion laws)...the number of unsafe abortions would decline by 73% from 20 million to 5.5 million."

Incidence
There are two commonly used methods of measuring the incidence of abortion:
Abortion rate – number of abortions per 1000 women between 15 and 44 years of age
Abortion ratio – number of abortions out of 100 known pregnancies (excluding miscarriages and stillbirths)
The number of abortions performed worldwide has remained stable in recent years, with 41.6& nbsp;million having been performed in 2003 and 43.8& nbsp;million having been performed in 2008. The abortion ratio worldwide was 28 per 1000 women, though it was 24 per 1000 women for developed countries and 29 per 1000 women for developing countries.
On average, the incidence of abortion is similar in countries with restrictive abortion laws and those with more liberal access to abortion. However, restrictive abortion laws are associated with increases in the percentage of abortions which are performed unsafely.Cite journal|author=Shah I, Ahman E |title=Unsafe abortion: global and regional incidence, trends, consequences, and challenges |journal= J Obstet Gynaecol Can |volume=31 |issue=12 |pages=1149–58 |year=2009 |month=December |pmid=20085681 |doi= |quote=However, a woman’s chance of having an abortion is similar whether she lives in a developed or a developing region: in 2003 the rates were 26 abortions per 1000 women aged 15 to 44 in developed areas and 29 per 1000 in developing areas.

Personal and social factors
The reasons why women have abortions are diverse and vary dramatically across the world. Some of the most common reasons are to postpone childbearing to a more suitable time or to focus energies and resources on existing children. Others include being unable to afford a child either in terms of the direct costs of raising a child or the loss of income while she is caring for the child, lack of support from the father, inability to afford additional children, desire to provide schooling for existing children, disruption of one's own education, relationship problems with their partner, a perception of being too young to have a child, unemployment, and not being willing to raise a child conceived as a result of rape or incest , among others.Cite journal|last1=Bankole|first1=Akinrinola |last2=Singh|first2=Susheela |last3=Haas|first3=Taylor |year=1998 |url= http://www.guttmacher.org/pubs/journals/2411798.html |title=Reasons Why Women Have Induced Abortions: Evidence from 27 Countries |journal=International Family Planning Perspectives |volume=24 |issue=3 |pages=117–127; 152Cite journal |last1=Finer |first1=L.

An American study in 2002 concluded that about half of women having abortions were using a form of birth control|contraception at the time of becoming pregnant. Inconsistent use was reported by half of those using condom s and three-quarters of those using the combined oral contraceptive pill|birth-control pill ; 42% of those using condoms reported failure through slipping or breakage.Cite journal |doi=10.2307/3097748 |last1=Jones |first1=R.

Some abortions are undergone as the result of societal pressures. These might include the preference for children of a specific sex, disapproval of single or early motherhood, stigmatization of people with disabilities, insufficient economic support for families, lack of access to or rejection of contraceptive methods, or efforts toward population control (such as China's one-child policy ). These factors can sometimes result in compulsory abortion or sex-selective abortion .
History
Main|History of abortionInduced abortion has long history, and can be traced back to civilizations as varied as China under Shennong (c. 2700 BCE), Ancient Egypt with its Ebers Papyrus (c. 1550 BCE), and the Roman Empire in the time of Juvenal (c. 200 CE).cite book|chapter=1.

In Europe and North America, abortion techniques advanced starting in the 17th century. However, conservatism by most physicians with regards to sexual matters prevented the wide expansion of safe abortion techniques. Other medical practitioners in addition to some physicians advertised their services, and they were not widely regulated until the 19th century, when the practice was banned in both the United States and the United Kingdom. Church groups as well as physicians were highly influential in anti-abortion movements. In the US, abortion was more dangerous than childbirth until about 1930 when incremental improvements in abortion procedures relative to childbirth made abortion safer.By 1930, medical procedures in the US had improved for both childbirth and abortion but not equally, and induced abortion in the first trimester had become safer than childbirth. In 1973, Roe vs. Wade acknowledged that abortion in the first trimester was safer than childbirth:

Society and culture
Abortion debate
Main|Abortion debateInduced abortion has long been the source of considerable debate, controversy, and activism. An individual's position concerning the complex ethical, moral, philosophical, biological, and legal issues which surround abortion is often related to his or her value system . Opinions of abortion may be described as being a combination of beliefs about abortion's morality the proper extent of governmental authority in public policy; and on the rights and responsibilities of the woman seeking to have an abortion. Ethics in religion|Religious ethics also has an religion and abortion|influence on both personal opinion and the greater debate over abortion.
In both public and private debate, arguments presented in favor of or against abortion access focus on either the moral permissibility of an induced abortion, or justification of laws permitting or restricting abortion. Abortion debates, especially pertaining to abortion law s, are often spearheaded by groups advocating one of these two positions. Anti-abortion groups who favor greater legal restrictions on abortion, including complete prohibition, most often describe themselves as "pro-life" while abortion rights groups who are against such legal restrictions describe themselves as "pro-choice". Generally, the former position argues that a human fetus is a human being with a right to life|right to live , making abortion morally the same as murder. The latter position argues that a woman has certain reproductive rights , especially the choice whether or not to carry a pregnancy to term.
Modern abortion law
Main|Abortion lawSee also|History of abortion law debate Current laws pertaining to abortion are diverse. Religious, moral, and cultural sensibilities continue to influence abortion laws throughout the world. The right to life, the right to liberty, the right to security of person , and the right to reproductive rights|reproductive health are major issues of human rights that are sometimes used as justification for the existence or absence of laws controlling abortion.
In jurisdictions where abortion is legal, certain requirements must often be met before a woman may obtain an abortion (an abortion performed without the woman's consent is considered feticide ). These requirements are usually dependent on the age of the fetus, often using a Pregnancy#Terminology|trimester -based system to regulate the window of legality. Many restrictions are waived in emergency situations. Some jurisdictions require a waiting period before the procedure, prescribe the distribution of information on prenatal development|fetal development , or require that minors and abortion|parents be contacted if their minor daughter requests an abortion.cite web|url= http://internationalfamilyplanningperspectives.org/pubs/MandatoryCounseling.pdf|title=The Impact of State Mandatory Counseling and Waiting Period Laws on Abortion: A Literature Review|format=PDF|publisher= Guttmacher Institute |author=Theodore J.

Other jurisdictions ban abortion almost entirely. Many, but not all, of these will allow them to be performed in a variety of circumstances. These circumstances vary based on jurisdiction, but may include whether the pregnancy is a result of rape or incest, whether the fetus' development is impaired, whether the mother's physical or mental well-being is endangered, or whether there are socioeconomic considerations that could be taken into consideration. In countries where abortion is banned entirely, such as Abortion in Nicaragua|Nicaragua , rises in maternal death directly and indirectly due to pregnancy have been noted.cite web|title=European delegation visits Nicaragua to examine effects of abortion ban |date=26 November 2007 |publisher=Ipas |accessdate=2009-06-15| url= http://www.ipas.org/Library/News/News_Items/European_delegation_visits_Nicaragua_to_examine_effects_of_abortion_ban.aspx| archiveurl= http://web.archive.org/web/20080417033829/ http://www.ipas.org/Library/News/News_Items/European_delegation_visits_Nicaragua_to_examine_effects_of_abortion_ban.aspx |archivedate=2008-04-17 |quote=More than 82 maternal deaths had been registered in Nicaragua since the change.

Sex-selective abortion
Main|Sex-selective abortion Medical ultrasonography|Sonography and amniocentesis allow parents to determine sex before childbirth. The development of this technology has led to sex-selective abortion and female infanticide|sex-selective abortion , or the termination of a fetus based on sex. The selective termination of a female fetus is most common.
Sex-selective abortion is partially responsible for the noticeable disparities between the birth rates of male and female children in some countries. The preference for male children is reported in many areas of Asia, and abortion used to limit female births has been reported in Taiwan, South Korea, India, and China.Banister, Judith.

"Abortion is commonly misunderstood outside medical circles. In general terms, the word 'abortion' simply means the failure of something to reach fulfilment or maturity. Medically, abortion means loss of the fetus, for any reason, before it is able to survive outside the womb. The term covers accidental or spontaneous ending, or miscarriage, of pregnancy as well as deliberate termination. The terms 'spontaneous abortion' and 'miscarriage' are synonymous and are defined as loss of the fetus before the twenty-eighth week of pregnancy. This definition implies a legal perception of the age at which a fetus can survive out of the womb. With great advances in recent years in the ability to keep very premature babies alive, this definition is in need of revision." cite encyclopedia|title=Abortion and miscarriage|encyclopedia=The Royal Society of Medicine Health Encyclopedia|location=London|publisher=Bloomsbury Publishing|year=2000
