Second trimester abortion law globally: actuality, trends and recommendations

In light of the need for second trimester abortions, one of the most important factors determining whether they can be safely obtained in a timely fashion is the law governing them and restrictions placed on them. Although there is a substantial body of academic literature on the legality of abortion in various countries, most of it focuses on the lawfulness of abortion in the first trimester [20], [21], [22], [23], [24], [25], [26].  Analyses of the legalityof abortion often do not specify indications or requirements for abortions performed later in pregnancy. This paper focuses on the legality of the procedure in the second trimester and is based, in all but a few cases, on the exact wording of the specific laws and, when available, in regulations for some 191 countries for which information is available .  It is structured around an analysis of the legality of second trimester abortion according to the most common indications for such abortions which appear in the laws themselves: to preserve the woman's life, physical and mental health reasons, pregnancy due to a sex offence, fetal impairment, socio-economic reasons, and at the woman's request.

As is the case with first trimester abortions, the law does not indicate the extent to which safe abortion is available in practice. This can vary considerably, based on factors such as the willingness of providers, the availability of services, and the attitude of officials and the public as a whole. Thus, while the abortion lawsin Great Britain and Ghana are very similar, abortion services are available to meet existing need in Britain but are lacking in Ghana [27]. Although it is beyond the scope of this paper to do such analyses, the language in the laws does provide useful information on their theoretical limits and the extent to which they could be applied, and serves as a starting point for further analysis of how they are applied in individual countries and how they can be changed to improve access.

It should be noted at the outset that there exist significant barriers to analysing the legal texts on second trimester abortions. In some cases, the language is convoluted or simply unclear. This can particularly be a problem in trying to determine the upper time limits (in weeks of pregnancy) set for legal abortions. Many laws do not establish time limits, no matter what the indication, while others specify (sometimes different) time limits for certain indications, but not for others. In other laws, a time limit must be inferred from the requirement that an abortion must be carried out before “viability”, a term that is about the chances of preterm survival in relation to wanted pregnancies and has no one accepted definition, [28], [29], [30], [31], [32] and arguably no relevance in relation to induced abortion. This paper therefore includes the term as it appears in specific laws, but without seeking to assign a specific meaning to it.

Interpretation of the health indication for abortion can also pose difficulties. The wording of this indication varies greatly from country to country, particularly given the range of languages and legal traditions involved. Sometimes, as in many common law-based laws, there must be a risk to health. Great Britain's law, for example, which has served many former British colonies as a model for reform, allows abortion where “continuance of the pregnancy would involve risk, greater than if the pregnancy were terminated, of injury to the physical or mental health of the pregnant woman…”. Sometimes, as in countries that follow a civil law tradition, there must be a danger to health. Burkina Faso's Penal Code permits abortions when “continuation of the pregnancy… endangers the health of the woman…”. And in some countries there must only be medical or health reasons. In Vanuatu, there must be “good medical reasons”, in Djibouti “therapeutic reasons”, and in Pakistan a requirement of “necessary treatment”. These concepts are not necessarily the same.

Moreover, the degree of risk or danger to health varies. Some laws provide that there must simply be a risk or danger, while others provide that there must be a serious risk or danger, or that an abortion is the only way to prevent serious and/or permanent harm to health. Argentina's Penal Code allows abortion “in order to avert danger to the life or health of the mother if this danger cannot be averted by other means”. As the authors of a recent study of the health indication conclude: “inconsistencies in countries' interpretation and implementation of the health indication and, depending on where women live, the medical practitioners they consult and their ability to defend themselves before public officials, can result in discrepancies in practice and discrimination” [33]. In addition, while in some laws only the term “health” is used, this may or may not encompass mental health as well physical health, in line with the current World Health Organization (WHO) definition of health as “a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity” [34].  However, the analysis that follows adopts a conservative approach; that is, mental health is most likely included only when the legal text actually employs the term.

The information in this paper was compiled through the author's personal examination in almost all instances of the full texts of the laws in the original language or in reliable translations . To the best of the author's knowledge the texts examined are up to date as of early 2010. The interpretation of laws reflects the best judgment of the author when the wording itself is unclear. Table 1 summarises the legal indications for second trimester abortion in 191 countries. When the provisions of a law are unclear or are implied, rather than clearly stated, as when a time limit is specified for some indications but not for others, or when abortion is defined as a procedure that is performed only up to a specific point during pregnancy, this is noted in the tables .

Almost all countries or jurisdictions in the world with specific laws on abortion allow abortion to preserve the life of the pregnant woman. Their laws specify this indication explicitly or, under general criminal law principles of necessity, are interpreted as permitting such abortions. In most cases, no upper time limit is set by these laws, and thus the laws can be presumed to allow such abortions throughout pregnancy . In the remaining cases, the upper time limit extends into the second trimester. Of the 191 laws reviewed, 188 allow abortion to preserve the woman's life. In Chile, El Salvador and Nicaragua, abortions are not permitted on any ground at any time during pregnancy .

Of these 188 countries' laws, 58 permit abortion only to preserve the life of the pregnant woman at any time during pregnancy; the rest also permit abortions on other grounds. All 58 countries, except Ireland, are developing countries and include some of the most populous and poorest countries in the world, e.g. Afghanistan, Nigeria, Myanmar, Philippines, Tanzania and Uganda. In addition, most are countries where very few legal abortions are performed. These laws are generally broadly worded and do not delineate procedures under which a pregnant woman or physician can request an abortion or specify conditions on facilities or personnel for their performance.
Many have not been revised since colonial days.

Some 113 countries allow abortion to be performed on health grounds during the second trimester. Twenty-five of the 113 countries permit abortion only to save the life of the pregnant woman or to preserve her health. These include Algeria, Argentina, Burundi, Malaysia, Morocco, Pakistan, Peru and Rwanda.

These 113 countries fall into two categories. The first consists of countries that permit abortion most likely only on physical health grounds. Their laws either use the phrase “risk to health” or “danger to health” or “for medical reasons” or specify risk or danger “to physical health”. Some 69 countries are in this category, approximately 67% of them developing countries. As noted earlier, it is often unclear whether “health” also includes mental health. Presumably, such an interpretation is more likely in a country that revised its abortion law after the WHO definition was formulated in 1946, than in a country with a law formulated prior to that

The second category consists of countries that specifically allow abortion for mental health reasons. Some 45 countries fall within this classification, slightly over half of them developing countries.

Only about 25% of the 113 countries' laws set time limits on abortion. These range from16 weeks (four countries) to 32 weeks (one country), and in seven countries at “viability”. Except for those that permit abortion on health grounds at any time during pregnancy, the remainder do not specify a time limit, so it is unclear whether abortions are allowed at any time during the second trimester or not. As is the case for most of the countries that permit abortions only to preserve the life of the pregnant woman, many of these countries' laws are broadly worded and fail to specify facilities, personnel or approval requirements for the performance of abortions.

The most common additional legal indication for second trimester abortion is fetal impairment or anomaly. This may reflect the growing sophistication and use of technology that can detect a genetic or physical abnormality, which is also increasingly available in developing countries. As with the health indication, interpretation of an indication of fetal impairment can pose difficulties. The most significant is a definition of what sort of fetal impairment is sufficiently serious to justify an abortion. This question has been addressed by some government ministries and medical professional associations. For example, in a position paper, the Netherlands Ministry of Health Welfare concluded that termination of pregnancy after 24 weeks was warranted in cases in which “the unborn child cannot reasonably be expected to survive outside the mother's body” or in which there are “fetal anomalies leading to serious and incurable functional disorders but which might reasonably be expected to have a chance of survival, although mostly a very limited one” [40]. In a 2010 report, the UK's Royal College of Obstetricians & Gynaecologists (RCOG) advised that a number of factors be considered, including the potential for effective treatment; the probable degree of self-awareness on the part of the child and of the ability to communicate with others; the suffering that would be experienced; the probability of the child being able to live alone and to be self-supporting as an adult; and on the part of society, the extent to which actions performed by individuals without disability that are essential for health would have to be provided by others [41]. The RCOG decided against specifying the types of fetal impairment that justify an abortion, and in fact almost no laws do so, as is also the case with the health indication.

Actual wording of the laws varies from country to country. In almost all countries the fetal impairment must be considered serious. For example, in Great Britain and many of its former colonies there must be “a substantial risk that if the child were born it would suffer from such physical or mental abnormalities as to be seriously handicapped”. In many countries the impairment must also be incurable. In France and a number of its former colonies, and countries influenced by French law, there must be “a strong possibility that the unborn child will suffer from a particularly serious condition recognized as incurable at the time of diagnosis”. A few countries, such as Israel, Nepal and Slovakia, however, specify neither requirement. Whether these differences in wording make a practical difference or not is unclear.

Some 69 countries specifically authorise abortions for this reason in the second trimester, almost evenly divided between developing and developed countries. Almost all of the countries that permit such abortions in the second trimester also authorise abortion in the second trimester for health reasons – only a few such as Cambodia, Iran, Mexico and Panama do not. Unlike the laws already discussed, the laws of most of these countries are usually detailed in nature and set forth requirements as to facilities, personnel, and approval procedures. Moreover, 42% of these countries set time limits on abortions for fetal impairment, ranging from 16 weeks (five countries) to 24 weeks (ten countries), “viability” (two countries) to 32 weeks (one country). This is a far greater percentage of countries setting such time limits than those setting limits for abortions on health grounds. However, even if an abortion cannot be performed on grounds of fetal impairment beyond a fixed upper time limit, it might well be justified on health grounds.

The next most common indication for second trimester abortions, after life, health, and fetal impairment, is if the pregnancy resulted from a sex offence, most commonly rape, and in some but not all cases, incest. There are some 49 countries whose laws include this indication, approximately half of them developed countries. Almost 80% are the same countries that authorise abortion for fetal impairment, and almost all also permit abortions for health reasons. 57% of these countries set time limits on such abortions. These range from 16 weeks (four countries) to “viability” (two countries), with a lower average time limit than for abortions on health or fetal impairment grounds (see Table 1 - download full article ). The lower time limitmay reflect a belief that a woman (or girl) should be able to seek an abortion for a pregnancy resulting from a sex offence earlier than for other reasons. However, there is some evidence that women may be delayed in reporting rape and therefore in being able to seek an early abortion [42].

Anumber of these countries also requiremore than the woman's statement that the pregnancy resulted from a sexual offence. For example, in Bolivia a prosecution must have been initiated. In Cameroon, there must be a certificate from the prosecutor of a good case. In Hong Kong, the woman must make a report to a police officer. In Zimbabwe, a complaint must be lodged with the authorities. At least 12 countries require the approval of a committee or of two ormore physicians.

Thirty-two countries allow second trimester abortions on broad socio-economic grounds. All of these countries also permit abortions for other reasons; 81% are developed countries or former Soviet republics or Soviet bloc countries that have long had liberal abortion laws. They include Great Britain, India, Japan, Russian Federation, South Africa and Ukraine. 69% set specific time limits for such abortions, ranging from 16 weeks (two countries) to 22 weeks (ten countries) to “viability” (two countries).

Some of the countries with this indication, including Denmark, Guyana, Norway, Russian Federation, South Africa, and most former Soviet republics, allow abortion on request in the first trimester of pregnancy; others, including Great Britain, Iceland, India and Zambia do not. A few countries authorise second trimester abortions for specific, limited socio-economic reasons, e.g. the pregnant woman/girl is of unsound mind (Bhutan, Hungary, New Zealand, Norway); the pregnancy is due to contraceptive failure (Guyana, India); the woman is HIVpositive (Guyana); the woman is over a specified age (Estonia, Israel); the pregnancy is the result of extramarital relations (Israel); the pregnancy was not discovered earlier (Hungary); the pregnant woman/girl or the father suffers from a genetic disease (Republic of Korea, Taiwan); the pregnant woman/girl is unable to care for a child (Denmark, Estonia, Ethiopia, Guyana); and the pregnant girl/woman is under a specified age (Austria, Estonia, Ethiopia, Finland, Hong Kong, Israel, Liechtenstein). The specified age varies from under 14 to under 18, to under the age of marriage. The last of these is notable in light of arguments for and against parental consent for minors to obtain an abortion in many countries.

Ten countries permit second trimester abortion on request. This contrasts with 54 countries that allow abortion on request only in the first trimester [21]. Four of the ten do not set upper time limits on second trimester abortions. Sweden specifies 18 weeks, Singapore 24 weeks, and the Netherlands and the United States “viability,” but all allow some abortions on specific grounds after that. Eight of the ten countries are either developed countries or former Soviet bloc countries. With notable exceptions, such as India and South Africa, countries allowing abortion for socio-economic reasons or on request in the second trimester are places where obtaining a second trimester abortion is relatively easy and safe [43], [44].

China does not have a specific abortion law at all, and in Canada abortion was decriminalized in 1988–89 when the Supreme Court ruled that the abortion provisions of Canada's Criminal Code violated the Canadian Charter of Rights and Freedoms, and the Parliament failed to enact new provisions [45].  Abortion may be assumed to be on request without legal restrictions in both countries. However, practice may still be restricted, including the availability of second trimester abortion services . In 2002, the Australian Capital Territory also decriminalised abortion without reference to length of pregnancy.

An analysis of the permitted indications and upper time limits for second trimester abortions tells only part of the story on the legal availability of the procedure. Many abortion laws establish additional conditions for carrying out abortions that can greatly affect access. One of these relates to who can perform abortions. Very few countries allow persons other than a physician to carry out a second trimester abortion, and some, such as Bulgaria, Greece, Libya, Madagascar, Seychelles and Turkey, mandate that the physician be an obstetrician/gynaecologist or have special training. However, this is now slowly changing for both first and second trimester medical abortions,   with trained nurses, midwives and other mid-level providers able to manage these abortions alone [46].  Moreover, many laws allow conscientious objection on the part of individual providers, although sometimes not if the life of the woman is at risk (e.g. Great Britain, Seychelles, Singapore and Zimbabwe).

A second restriction relates to sometimes time-consuming approval procedures for abortions. In many countries, such as Anguilla, Barbados, Bulgaria, Burundi and Cambodia, for example, two or more physicians or a commission must approve the abortion. Often these restrictions increase with the length of pregnancy, as in Barbados, Finland, Guyana and South Africa. Some laws also require the consent of a parent if the woman is a minor (e.g. Croatia, Poland, Saudi Arabia, Turkey) or a spouse if she is married (e.g. Equatorial Guinea, Japan, Kuwait). If such consent is not obtained, a woman usually has no legal recourse. Although a number of countries allow a court or medical
committee to authorise the abortion when a parent refuses (e.g. Denmark, Italy, several US states), this too can result in delay. In addition, some countries specify waiting/reflection periods before a woman can obtain an abortion (e.g. Belgium, Germany, Saint Lucia, Netherlands).

Another restriction relates to places where abortions can be carried out. A number of countries, such as Luxembourg, Montserrat, New Zealand, Singapore and Tunisia, require licensing or approval of abortion facilities. Others, such as Kuwait, Rwanda, Togo and Zambia, limit the performance of abortions to hospitals or similar institutions, while still others, such as Ethiopia, Israel, Serbia, Taiwan, Thailand and Turkey, set forth detailed requirements that an institution must meet in order to carry out abortions. A final requirement is the prohibition of abortion advertisements (e.g. Albania, Eritrea, Greece).

These restrictions may be intended to create barriers to providing and obtaining abortions, e.g. in many US states [52].  On the other hand, such requirements may be intended to protect women, e.g. to prevent abortions by unqualified personnel in unsafe facilities, as stated in guidelines adopted by Ethiopia and Viet Nam, for example. Moreover, it should not be inferred that if countries do not have conditions for the performance of second trimester abortions, it is easier to access them. On the contrary, these countries are more often places where very few legal abortions are carried out for any reason. Countries with such requirements have usually decided to allow abortion.

Nonetheless, the question of which requirements remain necessary, given the increasing safety and simplicity of providing second trimester abortions, particularly medical abortions in many settings, must be raised.

Table 2 (download full article ) summarises changes in second trimester abortion laws that have occurred since 1990. At least 30 countries have significantly expanded indications for abortion [20], [21].  These include Albania, Bhutan, Botswana, Cambodia, Colombia, Ethiopia, Fiji, Ghana, Guyana, Indonesia, Monaco, Nepal, Portugal, Saint Lucia, South Africa, Spain, Swaziland, Switzerland and Thailand. Five West African Francophone countries liberalised their abortion laws by means of comprehensive reproductive health legislation as well, and Kenya's new Constitution, approved by referendum in August 2010, allows abortion on grounds of life and health and leaves open the possibility that a law could subsequently be enacted that permits abortion on additional grounds. Almost all of these changes affect the legal status of second trimester abortions, whether by increasing indications for abortion without setting upper time limits, by endorsing specific indications for abortion with time limits, or both [20], [21].  In addition, many countries have registered the use of mifepristone and/or misoprostol for inducing abortion, often only for the first nine weeks of pregnancy, [53], [54]  but off-label use in the second trimester is common, (Beverly Winikoff, Expanding access through off-label use of medical abortion, conference presentation, March 2010), [1]  e.g. in Great Britain and the US, and across Scandinavia.

At the same time there have been moves in some countries to lower the upper time limit for second trimester abortions. In 2009, following developments in many former Soviet republics, Turkmenistan reduced the upper time limit on abortion for social reasons from28 to 22 weeks. In Spain, although the new abortion law liberalised abortion by allowing it on request during the first 14 weeks of pregnancy, it also placed a time limit of 22 weeks on abortions performed when the health of the pregnant woman is threatened. In 2003, the Russian Federation reduced the more than ten socio-economic indications for abortions between 12 and 22 weeks to four: in cases where a court rules a woman is unfit to be a mother, in the case of rape, where the father is either very sick or dies, or where the woman is sent to prison [20], [55].

Similarly some countries are placing greater procedural restrictions on the performance of abortions later in pregnancy. In 2009, for example, Germany added new procedural requirements relating to the provision of information and a reflection period for abortions sought on grounds of fetal impairment. Some proponents of these changes were said to want to create barriers to these abortions, while others were concerned that women were not getting the counselling they needed when fetal impairments were detected. In 2007, the US Supreme Court upheld a ban on a particular form of D&E used in the second trimester, following a successful campaign against it by the anti-abortion movement [56].

It is not entirely clear what is driving moves to restrict the performance of abortions after the first trimester. The proponents of such changes often argue that advances in medical technology have allowed prematurely born babies to survive at earlier ages and, thus the abortion time limit should be lowered to below 24 weeks of pregnancy. As the authors of a recent study on post-first trimester abortions in England and Wales point out, however, these critics seldom question the ethics of restricting access to abortion or acknowledge the compelling reasons that lead women to have abortions after the first trimester [10].  In any case, there is no scientific support for such changes [28], [32].  One of the few bodies that examined the evidence in detail, the UK Parliament's Science and Technology Committee, concluded in 2007 that there was no justification for lowering the legal time limit on abortion [29].

Key findings of this review are summarised in Box 1. Given that there are serious reasons why women have second trimester abortions, and that the laws in many countries do not make such abortions available, an important question to ask is how laws and regulations can be changed in order better to respond to women's
needs, as well as to reduce delays in accessing abortions as early as possible. In 2007, the International Conference on Second Trimester Abortion, organised by the International Consortium for Medical Abortion, adopted recommendations that take a forward-looking approach [57]. These include that abortion be completely decriminalised and made available at a woman's request. Short of that, they propose that the health indication for abortion should include mental as well as physical health, that judicial or administrative
approval requirements for abortion following sex offences be removed, that there should be no upper time limit on abortions, and that regulatory conditions whose purpose is to impose access barriers be removed.

WHO's 2003 Safe Abortion: Technical and Policy Guidance for Health Systems contains a detailed analysis of access barriers and recommendations for their removal [17].  For example, it proposes reducing or eliminating administrative and regulatory barriers in areas such as physician or committee authorisation, restrictive time limits, waiting periods, spousal and parental approval, facility and physician-only requirements, fees, licensing, and the reporting of rape. The broader aim of this guidance and its technical and policy recommendations is to provide evidence-based recommendations for making all abortions safe.

While it may be politically unrealistic to expect most countries to decriminalise all abortions in the near future, especially in the second trimester, less comprehensive legislative and regulatory changes are possible. These include recommendations aimed at ensuring that abortions are carried out as early as possible in pregnancy, and improving women's access to safe abortions through the removal of clinically unnecessary legal and regulatory restrictions.

All countries should allow abortions to preserve the woman's life, for broad physical and mental health reasons, and in cases of rape, incest and fetal impairment throughout the first and second trimesters of pregnancy. Moreover, countries could amend requirements on facilities and providers so that they are evidencebased, reflect current best practice and aim only to protect the health of the woman. Best practice with regards to induced abortion has changed substantially in the past 20+ years, and laws and regulations need to have the flexibility built into them to respond to these changes, both on grounds of safety and to keep costs as low as possible for women and health systems. For example, nurses, midwives, and other mid-level providers with appropriate training could be authorized to manage both first and second trimester medical abortion in modest inpatient facilities with good referral links for emergency medical care for the very small proportion of women who may need it [47].  In addition, there should be no requirement that a commission or more than one physician authorize any abortion.

Spousal approval should never be necessary. Serious consideration should also be given to removing requirements for parental approval for minors to obtain an abortion, particularly where rape and incest may have been involved. Moreover, there should be no requirement that rape be reported or investigated, or that a magistrate give approval for abortions performed on this ground. In general, laws and regulations should be based on scientific evidence, be clear and uniform, and facilitate access to legal abortions. This would signal a government's commitment to allowing legal abortions to be performed, and allow women, health service
managers, health and legal professionals and the public to understand the parameters of the law. It would also make it possible for improvements in abortion methods, which have developed continuously since 1980, to be incorporated into service delivery without delays, as currently occurs due to outdated laws and regulations, and support training for providers, so that out-of-date and less safe methods stop being used.

Regulations should call for the expeditious referral of patients seeking abortions by health personnel to an abortion provider, and their expeditious treatment once they have been referred. There is a growing body of sentiment that health care professionals who assert a “conscientious objection” and their institutions still have a duty to ensure that their patients have access to abortion [48], [49], [50], [51].  Furthermore, governments should oversee and monitor the implementation of conscientious objection clauses so that women can actually access the services they are legally entitled to receive.

Governments should create women-supportive services that ensure privacy, confidentiality and compassionate and non-judgmental treatment,taking into account the experiences and needs of adolescents, and young and poor women especially. They should ensure thatwomen, health personnel and the public in general are educated about the law and where to obtain safe abortion information and services. They should consider providing abortion services free of charge or ensuring that costs do not prevent any woman who needs an abortion from having one.

Training for health personnel in safe abortion procedures, including for second trimester abortions, and addressing the emotional needs of women seeking abortions through provision of accurate information, and unbiased counselling (if requested by the woman), should be a required part of pre-service training for physicians and nurses in any country where abortion is legal for at least one indication. Lastly, improving
access to early pregnancy testing, strengthening sex education and access to contraception, particularly for under-served groups such as adolescents and single women and men, the poor and rural populations, would go a long way towards reducing unwanted pregnancies. UNESCO has recently published helpful guidance on this issue [59].  These measures would address women's need for safe, legal first and second trimester abortions in a comprehensive fashion.
