Late termination of pregnancy


Late termination of pregnancy describes the termination of pregnancy by induced abortion during a late stage of gestation. "Late", in this context, is not precisely defined, and different medical publications use varying gestational age thresholds. In 2015 in the United States, about 1.3% of abortions took place after the 21st week, and less than 1% occur after 24 weeks.
Reasons for late terminations of pregnancy include circumstances where a pregnant woman's health is at risk or when lethal fetal abnormalities have been detected. Later abortion is not associated with any negative physical or mental health outcomes, and the risk of death following a surgical abortion after 20 weeks is less than that of typical full-term childbirth in the United States.
Late termination of pregnancy is more politically controversial than abortion in general. Most countries in Europe only permit abortion in later stages of pregnancy if specific circumstances are present, generally when the pregnancy represents a serious danger to the life, or to the physical or mental health of the woman, or when a serious malformation or anomaly of the fœtus is diagnosed. The American College of Obstetricians and Gynecologists states with respect to abortion that "politicians should never interfere in the patient-physician relationship".

Definition

A late termination of pregnancy often refers to an induced ending of pregnancy after the 20th week of gestation, i.e. after a fetal age of about 18 weeks. The exact point when a pregnancy becomes late-term, however, is not clearly defined. In three articles published in 1998 in the same issue of the Journal of the American Medical Association two chose the 20th week of gestation and one chose the 28th week of gestation as the point where an abortion procedure would be considered late-term.
In the US, the point at which an abortion becomes late-term is often related to the "viability" of the fetus. Sometimes late-term abortions are referred to as post-viability abortions, though this is not a medical term.

Viability

There is no sharp limit of development, age, or weight at which a fetus becomes viable. A 2015 study found that even with active treatment, no infants born at less than 22 weeks survived, at 23 weeks survival without severe impairment is less than 2%, and at 25 weeks, up to 30% might survive without severe impairment. According to studies between 2003 and 2005, 20 to 35 percent of babies born at 24 weeks of gestation survived, while 50 to 70 percent of babies born at 25 weeks, and more than 90 percent born at 26 to 27 weeks, survived. The American College of Obstetricians and Gynecologists and the Society for Maternal and Fetal Medicine states that in cases of delivery occurring before 26 weeks, “given the potential for maternal and perinatal mortality and morbidity, the option of pregnancy termination should be reviewed with the patients.” Because the chance of survival is variable based on interventions available and the weight and sex of the fetus, there is no consensus on viability.
The American College of Obstetricians and Gynecologists reports that 23% of abortion providers offer abortions at 20 weeks of gestation and later, most often using a method called dilation and evacuation.

Mental health

A wanted abortion in any trimester is not associated with mental health harms. Overall, abortion does not increase the risk of experiencing symptoms of depression, anxiety or stress in the short term or over five years. A previous history of mental health conditions, sexual assault, and intimate partner violence were strongly associated with experiencing negative mental health outcomes after the abortion.

Incidence

United States

Reasons for late terminations of pregnancy include when a pregnant woman's health is at risk or when lethal fetal abnormalities have been detected.
A study from 2013 found after excluding abortion "on grounds of fetal anomaly or life endangerment", that women seeking late abortions "fit at least one of five profiles: They were raising children alone, were depressed or using illicit substances, were in conflict with a male partner or experiencing domestic violence, had trouble deciding and then had access problems, or were young and nulliparous". They concluded that "bans on abortion after 20 weeks will disproportionately affect young women and women with limited financial resources".

England and Wales

The NHS records the reasons given for abortions at all stages of development. In 2015, 2,877 abortions were performed at 20 weeks or above, and only 230 of these at or beyond 24 weeks gestation. Of all abortions at 20 weeks or above, 23 were performed to save the life of the pregnant woman, 1,801 were performed for mental or physical health reasons, and 1046 were performed because of foetal abnormalities.

Legal restrictions

As of 1998, among the 152 most populous countries, 54 either banned abortion entirely or permitted it only to save the life of the pregnant woman.
On the other hand, as of 1998, 49 of the 152 most populous countries allowed abortion without restriction as to reason, but 44 of these required specific justification after a particular gestational age:
Dutch Criminal Code defines the "viability" of a fœtus to 24 weeks, but doctors de facto limit on-request abortions to 22 weeks as a margin of error.
As of 2011 among those countries that allowed abortion without restriction as to reason, the gestational limits for such abortions on request were: 37 countries set a gestational limit of 12 weeks, 7 countries of 14 weeks, 4 did not set limits, 3 at viability, 3 at 10 weeks, one at 90 days, one at 8 weeks, one at 18 weeks, and one at 24 weeks. In addition, Abortion in Australia, and, to a certain extent, Abortion in the United States, is regulated at state/territory level, and laws vary by region.
In these countries, abortions after the general gestational age limit are allowed only under restricted circumstances, which include, depending on country, risk to the woman's life, physical or mental health, fetal malformation, cases where the pregnancy was the result of rape, or poor socio-economic conditions. For instance, in Italy, abortion is allowed on request up until 90 days, after which it is allowed only if the pregnancy or childbirth pose a threat to the woman's life, a risk to physical health of the woman, a risk to mental health of the woman; if there is a risk of fetal malformation; or if the pregnancy is the result of rape or other sexual crime. Denmark provides a wider range of reasons, including social and economic ones, which can be invoked by a woman who seeks an abortion after 12 weeks.
Abortions at such stages must in general be approved by a doctor or a special committee, unlike early abortions which are performed on demand. The ease with which the doctor or the committee allows a late term abortion varies significantly by country, and is often influenced by the social and religious views prevalent in that region.
Some countries, like Canada, China and Vietnam have no legal limit on when an abortion can be performed.

United States

The United States Supreme Court decisions on abortion, including Roe v. Wade, allow states to impose more restrictions on post-viability abortions than during the earlier stages of pregnancy.
As of December 2014, forty-two states had bans on late-term abortions that were not facially unconstitutional under Roe v. Wade or enjoined by court order. In addition, the Supreme Court in the case of Gonzales v. Carhart ruled that Congress may ban certain late-term abortion techniques, "both previability and postviability", as it had done in banning intact dilation and extraction with the Partial-Birth Abortion Ban Act of 2003.
The Supreme Court has held that bans must include exceptions for threats to the woman's life, physical health, and mental health, but four states allow late-term abortions only when the woman's life is at risk; four allow them when the woman's life or physical health is at risk, but use a definition of health that pro-choice organizations believe is impermissibly narrow. Note that just because a portion of a state's law is found to be unconstitutional does not mean that the entire law will be deemed unconstitutional: "nvalidating the statute entirely is not always necessary or justified, for lower courts may be able to render narrower declaratory and injunctive relief," meaning the court could declare that only those parts of the law that are violative of the Constitution are invalid, or that the court can prohibit the state from enforcing those portions of the law.
Eighteen states prohibit abortion after a certain number of weeks' gestation. The U.S. Supreme Court held in Webster v. Reproductive Health Services that a statute may create "a presumption of viability" after a certain number of weeks, in which case the physician must be given an opportunity to rebut the presumption by performing tests. Because this provision is not explicitly written into these state laws, as it was in the Missouri law examined in Webster, pro-choice organizations believe that such a state law is unconstitutional, but only "to the extent that it prohibits pre-viability abortions".
Ten states require a second physician's approval before a late-term abortion can be performed. The U.S. Supreme Court struck down a requirement of "confirmation by two other physicians" because "acquiescence by co-practitioners has no rational connection with a patient's needs and unduly infringes on the physician's right to practice". Pro-choice organizations, such as the Guttmacher Institute, posit that some of these state laws are unconstitutional, based on these and other Supreme Court rulings, at least to the extent that these state laws require approval of a second or third physician.
Thirteen states have laws that require a second physician to be present during late-term abortion procedures in order to treat a fetus if born alive. The Court has held that a doctor's right to practice is not infringed by requiring a second physician to be present at abortions performed after viability in order to assist in the case of a living fetus. It is not common for live infants to be born after an abortion at any stage in pregnancy.

Live birth

In 2019, a US Senate Bill entitled the "Born-Alive Abortion Survivors Protection Act" raised the issue of live birth after abortion. The bill would mandate that medical providers resuscitate neonates delivered showing signs of life during an abortion process. During the debate around this issue, US Republicans falsely alleged that medical providers "execute" live-born babies. Existing US laws would punish execution as homicide. Furthermore, US abortion experts refute the claim that a "born-alive" fetus is a common event and reject laws that would mandate resuscitation against the wishes of the parents.
Only 1.3% of abortions occur after 21 weeks of pregnancy in the US. Although it is very uncommon, women undergoing surgical abortion after this gestational age sometimes give birth to a fetus that may survive briefly. The periviable period is considered to be between 20 and 25 weeks gestation. Long-term survival is possible after 22 weeks. However, odds of long-term survival between 22 and 23 weeks are 2–3 percent and odds of survival between 23 and 24 weeks are 20 percent. "Intact survival", which means survival of a neonate without subsequent damage to organs such as the brain or bowel is 1% at 22 weeks and 13% at 23 weeks. Survival odds increase with increasing gestational age.
If medical staff observe signs of life, they may be required to provide care: emergency medical care if the child has a good chance of survival and palliative care if not. Induced fetal demise before termination of pregnancy after 20–21 weeks gestation is recommended by some sources to avoid this and to comply with the US Partial Birth Abortion Ban. Induced fetal demise does not improve the safety of an abortion procedure and may incur risks to the health of the woman having the abortion.

There are at least four medical procedures associated with late-term abortions:
