ABORT stands for interrupt or suppress as denoted by AB for NOT or AWAY and ORIRI for arise. In his sense, nature and people can "abort" or put "away" plans as well as pregnancies.

Urine tests can detect unplanned - unwanted pregnancy.

Undoubtedly, public debates about abortion related issues are injecting new overtones to the terms "abortion" and "miscarriage". In the USA, popular use of "abort" places stress on "induced" abortion and "miscarriage" implies "spontaneous" abortion. However, "miscarriage" can also mean "induced" as in "miscarriage" of justice.

Abortion implies a RUPTure or "interRUPTion" of a process. In fact, many aborted gestations are associated with the rupture of fetal membranes.

Ruptured fetal membranes cause abortions.

Nearly 20% of pregnancies end in spontaneous abortions. An even greater proportion of pregnancies are "interrupted" by humans, mainly because most pregnancies are unplanned and undesired. In Ukraine, during 1999, nearly as many pregnancies were interrupted as there were births. Similar figures apply to the rest of the former USSR empire, the USA and other "developed" societies.

Alcohol inhibits inhibitions.
Mothers may be drunk for a day - the unborn may become "drunk" for a lifetime.

Nearly 50% of spontaneous abortions are due to fatal fetal chromosomal defects and the frequency of fatal structural fetal defects is nearly as high. In addition, many environmental drugs and infectious agents can "disrupt" fetal development and if so, such agents are TERATOGENIC. The high level of spontaneous elimination of flawed embryos is, according to some, a form of  natural EUTHANASIA or a process to diminish the proportion of unviable offspring.

EUTHANASIA denotes a rather strange idea combining EU for happy and THANASIA for death. The view that biologic death can be happy is rather ABerrant. Since euthanasia is not suicide but an act of one party causing the death of another, In the case of induced abortions the "happy" party, "presumably", is the prospective mother or perpetrator.

Thanatos has to do with Teratothanasia.

An alternative to "therapeutic" or induced abortions are spontaneous (normal) abortions resulting from TERATOTHANASIA from TERATOS and THANATOS (deadly embryonic-fetal flaws). This idea has roots in Mythology. THANATOS personifies death and his twin brother HYPNOS, personifies sleep (a reversible oblivion). Poets assert that Thanatos eases the pain of mortals who have to leave this world toward Hades by granting the dying permanent sleep to ease their longings for worldly matters.

Some scientists have proposed that teratothanasia could be scientifically enhanced which would diminish the demand for induced abortions. For example, it is known that as women age, their chances rise rapidly to have a child with a chromosomal trisomy associated with such disorders as DOWN syndrome. Perhaps, an aging  organism is less able to detect and eliminate flawed fetuses. Notably, while the number of women delivering infants after the age of 35 years is relatively small, they contribute over half of infants with chromosomal trisomies, mainly Down Syndrome. A Discovery of agents that selectively enhance teratothanasia without harm to normal embryos could "eliminate" those who are flawed. (abnormal embryos may be more sensitive to some environmental agents).

Reproductive imperative is a powerful force relying on seduction.
Inbreeding and incest increase teratothanasia.
