Abortion
Abortion is the early termination of a pregnancy by removal or expulsion of an embryo or fetus. Abortions that occur without intervention are known as miscarriages or "spontaneous abortions", and occur in roughly 30–40% of all pregnancies. Deliberate actions to end a pregnancy are called induced abortion, or less frequently "induced miscarriage". The unmodified word ''abortion'' generally refers to induced abortion. Common reasons for having an abortion are birth-timing and limiting family size. Other reasons include maternal health, an inability to afford a child, domestic violence, lack of support, feelings of being too young, wishing to complete an education or advance a career, or not being able or willing to raise a child conceived as a result of rape or incest. When done legally in industrialized societies, induced abortion is one of the safest procedures in medicine. Modern methods use medication or surgery for abortions.

Medical Abortion
A medical abortion, also known as medication abortion or non-surgical abortion, occurs when drugs (medication) are used to bring about an abortion. Medical abortions are an alternative to surgical (also called procedural or instrumentation) abortions such as vacuum aspiration or dilation and curettage. Medical abortions are more common than surgical abortions in most places around the world. Medical abortions are most commonly performed by administering a two-drug combination: mifepristone followed by misoprostol. This two-drug combination is more effective than other drug combinations. When mifepristone is not available, misoprostol alone may be used in some situations. Medical abortion is both safe and effective throughout a range of Gestational age, gestational ages, including the second and third trimester. It gets progressively riskier and less effective as the pregnancy advances, especially in third trimester. In the United States, the mortality rate for medical abortio ...

Mifepristone
Mifepristone, and also known by its developmental code name RU-486, is a drug typically used in combination with misoprostol to bring about a medical abortion during pregnancy. This combination is 97% effective during the first 63 days (9 weeks) of pregnancy, yet effective in the second trimester as well. It is also used on its own to treat Cushing's syndrome or for use as a low-dose Emergency contraception, emergency contraceptive. The most common adverse effects include abdominal pain, feeling tired, and vaginal bleeding. Serious side effects may include heavy vaginal bleeding, bacterial infection, and, if pregnant, birth defects. When used, appropriate follow-up care needs to be available. Mifepristone is primarily an antiprogestogen. It works by blocking the effects of progesterone, making both the cervix and uterine vessels dilate and causing uterine contraction. Mifepristone also works, to a less extent, as an antiglucocorticoid and diminishes the effects of hypercortis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-managed Abortion
A self-induced abortion (also called a self-managed abortion, or sometimes a self-induced miscarriage) is an abortion performed by the pregnant woman herself, or with the help of other, non-medical assistance. Although the term includes abortions induced outside of a clinical setting with legal, sometimes over-the-counter medication, it also refers to efforts to terminate a pregnancy through alternative, potentially more dangerous methods. Such practices may present a threat to the health of women in the case that they are incorrectly used. Self-induced (or self-managed) abortion is often attempted during the beginning of pregnancy (the first eight weeks from the last menstrual period). In recent years, significant reductions in maternal death and injury resulting from self-induced abortions have been attributed to the increasing availability of misoprostol (known commercially as "Cytotec"). This medication is a synthetic prostaglandin E1 that is inexpensive, widely available, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dilation And Evacuation
Dilation and evacuation (D&E) or dilatation and evacuation (British English) is the dilation of the cervix and surgical evacuation of the uterus (potentially including the fetus, placenta and other tissue) after the first trimester of pregnancy. It is the most common method and procedure for abortions in the second trimester of pregnancy. The procedure can also be used to remove a miscarried fetus from the womb. In various health care centers it may be called by different names: * D&E (dilation and evacuation) * ERPOC (evacuation of retained products of conception) * TOP or STOP ((surgical) termination of pregnancy) D&E normally refers to a specific second trimester procedure. However, some sources use the term D&E to refer more generally to any procedure that involves the processes of dilation and evacuation, which includes the first trimester procedures of manual and electric vacuum aspiration. Intact dilation and extraction (D&X) is a different procedural variation on D&E. D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Definitions Of Abortion
Definitions of abortion vary from one source to another. Abortion has many definitions that can differ from each other in significant ways. Given the contentious nature of abortion, lawmakers and other stakeholders often face controversy in defining abortion. Language referring to abortion often reflects societal and political opinions (not only scientific knowledge). Influential non-state actors like the United Nations and the Roman Catholic Church have also engendered controversy over efforts to define abortion. Late termination of pregnancy is the term usually used for later uterine evacuation. Concerns in the medical community Ambiguous definitions can create concerns in the medical community. Physicians in several countries, including Ireland and Canada, have expressed concern over ambiguous definitions of abortion. Even in situations where there is a clear definition of abortion, it does not always match definitions of related terms in effect in the same jurisdiction. Exam ...

Miscarriage
Miscarriage, also known in medical terms as a spontaneous abortion, is an end to pregnancy resulting in the loss and expulsion of an embryo or fetus from the womb before it can fetal viability, survive independently. Miscarriage before 6 weeks of gestation is defined as biochemical loss by European Society of Human Reproduction and Embryology, ESHRE. Once ultrasound or histological evidence shows that a pregnancy has existed, the term used is clinical miscarriage, which can be "early" (before 12 weeks) or "late" (between 12 and 21 weeks). Spontaneous fetal termination after 20 weeks of gestation is known as a stillbirth. The term ''miscarriage'' is sometimes used to refer to all forms of pregnancy loss and pregnancy with abortive outcomes before 20 weeks of gestation. The most common symptom of a miscarriage is vaginal bleeding, with or without pain. Tissue (biology), Tissue and clot-like material may leave the uterus and pass through and out of the vagina.

Vacuum Aspiration
Vacuum or suction aspiration is a procedure that uses a vacuum source to remove an embryo or fetus through the cervix. The procedure is performed to induce abortion, as a treatment for incomplete spontaneous abortion (otherwise commonly known as miscarriage) or retained fetal and placental tissue, or to obtain a sample of uterine lining ( endometrial biopsy). It is generally safe, and serious complications rarely occur. Some sources may use the terms '' dilation and evacuation'' or "suction" ''dilation and curettage'' to refer to vacuum aspiration, although those terms are normally used to refer to distinctly different procedures. History Vacuuming as a means of removing the uterine contents, rather than the previous use of a hard metal curette, was pioneered in 1958 by Drs Wu Yuantai and Wu Xianzhen in China, but their paper was only translated into English on the fiftieth anniversary of the study which would ultimately pave the way for this procedure becoming exceedingly common ...

Birth Control
Birth control, also known as contraception, anticonception, and fertility control, is the use of methods or devices to prevent pregnancy. Birth control has been used since ancient times, but effective and safe methods of birth control only became available in the 20th century. Planning, making available, and using human birth control is called family planning. Some cultures limit or discourage access to birth control because they consider it to be morally, religiously, or politically undesirable. The World Health Organization and United States Centers for Disease Control and Prevention provide guidance on the safety of birth control methods among women with specific medical conditions. The most effective methods of birth control are sterilization by means of vasectomy in males and tubal ligation in females, intrauterine devices (IUDs), and implantable birth control. This is followed by a number of hormone-based methods including contraceptive pills, patches, vaginal r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trimester (pregnancy)
Pregnancy is the time during which one or more offspring gestates inside a woman's uterus. A multiple pregnancy involves more than one offspring, such as with twins. Conception usually occurs following vaginal intercourse, but can also occur through assisted reproductive technology procedures. A pregnancy may end in a live birth, a miscarriage, an induced abortion, or a stillbirth. Childbirth typically occurs around 40 weeks from the start of the last menstrual period (LMP), a span known as the ''gestational age''; this is just over nine months. Counting by ''fertilization age'', the length is about 38 weeks. Implantation occurs on average 8–9 days after fertilization. An ''embryo'' is the term for the developing offspring during the first seven weeks following implantation (i.e. ten weeks' gestational age), after which the term ''fetus'' is used until the birth of a ''baby''. Signs and symptoms of early pregnancy may include missed periods, ten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
