Vivisection (from Latin vivus 'alive'and sectio 'cutting') is surgery conducted for experimental purposes on a living organism, typically animals with a central nervous system, to view living internal structure. The word is, more broadly, used as a pejorative [1] catch-all term for experimentation on live animals [2] [3] [4] by organizations opposed to animal experimentation, [5] but the term is rarely used by practicing scientists. [3] [6] Human vivisection, such as live organ harvesting, has been perpetrated as a form of torture. [7] [8]

Research requiring vivisection techniques that cannot be met through other means is often subject to an external ethics review in conception and implementation, and in many jurisdictions use of anesthesia is legally mandated for any surgery likely to cause pain to any vertebrate. [9]
In the United States, the Animal Welfare Act explicitly requires that any procedure that may cause pain use "tranquilizers, analgesics, and anesthetics" with exceptions when "scientifically necessary". [10] The act does not define "scientific necessity" or regulate specific scientific procedures, [11] but approval or rejection of individual techniques in each federally funded lab is determined on a case-by-case basis by the Institutional Animal Care and Use Committee, which contains at least one veterinarian, one scientist, one non-scientist, and one other individual from outside the university. [12]
In the United Kingdom, any experiment involving vivisection must be licensed by the Home Secretary. The Animals (Scientific Procedures) Act 1986 "expressly directs that, in determining whether to grant a licence for an experimental project, 'the Secretary of State shall weigh the likely adverse effects on the animals concerned against the benefit likely to accrue.'" [13]
In Australia, the Code of Practice "requires that all experiments must be approved by an Animal Experimentation Ethics Committee" that includes a "person with an interest in animal welfare who is not employed by the institution conducting the experiment, and an additional independent person not involved in animal experimentation." [14]
Anti-vivisectionists have played roles in the emergence of the animal welfare and animal rights movements, arguing that animals and humans have the same natural rights as living creatures, and that it is inherently immoral to inflict pain or injury on another living creature, regardless of the purpose or potential benefit to mankind. [5] [15]
At the turn of the 19th century, medicine was undergoing a transformation. The emergence of hospitals and the development of more advanced medical tools such as the stethoscope are but a few of the changes in the medical field. [16] There was also an increased recognition that medical practices needed to be improved, as many of the current therapeutics were based on unproven, traditional theories that may or may not have helped the patient recover. The demand for more effective treatment shifted emphasis to research with the goal of understanding disease mechanisms and anatomy. [16] This shift had a few effects, one of which was the rise in patient experimentation, leading to some moral questions about what was acceptable in clinical trials and what was not. An easy solution to the moral problem was to use animals in vivisection experiments, so as not to endanger human patients. This, however, had its own set of moral obstacles, leading to the anti-vivisection movement. [16]
One polarizing figure in the anti-vivisection movement was François Magendie. Magendie was a physiologist at the Académie Royale de Médecine in France, established in the first half of the 19th century. [16] Magendie made several groundbreaking medical discoveries, but was far more aggressive than some of his contemporaries in the use of animal experimentation. For example, the discovery of the different functionalities of dorsal and ventral spinal nerve roots was achieved by both Magendie, as well as a Scottish anatomist named Charles Bell. Bell used an unconscious rabbit because of "the protracted cruelty of the dissection", which caused him to miss that the dorsal roots were also responsible for sensory information. Magendie, on the other hand, used conscious, six-week-old puppies for his own experiments. [16] [17] While Magendie's approach would today be considered an abuse of animal rights, both Bell and Magendie used the same rationalization for vivisection: the cost of animal experimentation being worth it for the benefit of humanity. [17]
Many[ who? ] viewed Magendie's work as cruel and unnecessarily torturous. One note is that Magendie carried out many of his experiments before the advent of anesthesia, but even after ether was discovered it was not used in any of his experiments or classes. [16] Even during the period before anesthesia, other physiologists[ who? ] expressed their disgust with how he conducted his work. One such visiting American physiologist describes the animals as "victims" and the apparent sadism that Magendie displayed when teaching his classes.[ verify ] Magendie's experiments were cited in the drafting of the British Cruelty to Animals Act 1876 and Cruel Treatment of Cattle Act 1822, otherwise known as Martin's Act. [16] The latter bill's namesake, Irish MP and well known anti-cruelty campaigner Richard Martin, called Magendie a "disgrace to Society" and his public vivisections "anatomical theatres" following a prolonged dissection of a greyhound which attracted wide public comment. [18] Magendie faced widespread opposition in British society, among the general public but also his contemporaries, including William Sharpey who described his experiments aside from cruel as "purposeless" and "without sufficient object", a feeling he claimed was shared among other physiologists. [19]
The Cruelty to Animals Act, 1876 in Britain determined that one could only conduct vivisection on animals with the appropriate license from the state, and that the work the physiologist was doing had to be original and absolutely necessary. [20] The stage was set for such legislation by physiologist David Ferrier. Ferrier was a pioneer in understanding the brain and used animals to show that certain locales of the brain corresponded to bodily movement elsewhere in the body in 1873. He put these animals to sleep, and caused them to move unconsciously with a probe. Ferrier was successful, but many decried his use of animals in his experiments. Some of these arguments came from a religious standpoint. Some were concerned that Ferrier's experiments would separate God from the mind of man in the name of science. [20] Some of the anti-vivisection movement in England had its roots in Evangelicalism and Quakerism. These religions already had a distrust for science, only intensified by the recent publishing of Darwin's Theory of Evolution in 1859. [17]
Neither side was pleased with how the Cruelty to Animals Act 1876 was passed. The scientific community felt as though the government was restricting their ability to compete with the quickly advancing France and Germany with new regulations. The anti-vivisection movement was also unhappy, but because they believed that it was a concession to scientists for allowing vivisection to continue at all. [20] Ferrier would continue to vex the anti-vivisection movement in Britain with his experiments when he had a debate with his German opponent, Friedrich Goltz. They would effectively enter the vivisection arena, with Ferrier presenting a monkey, and Goltz presenting a dog, both of which had already been operated on. Ferrier won the debate, but did not have a license, leading the anti-vivisection movement to sue him in 1881. Ferrier was not found guilty, as his assistant was the one operating, and his assistant did have a license. [20] Ferrier and his practices gained public support, leaving the anti-vivisection movement scrambling. They made the moral argument that given recent developments, scientists would venture into more extreme practices to operating on "the cripple, the mute, the idiot, the convict, the pauper, to enhance the 'interest' of [the physiologist's] experiments". [20]
In the early 20th-century the anti-vivisection movement attracted many female supporters associated with women's suffrage. [21] The American Anti-Vivisection Society advocated total abolition of vivisection whilst others such as the American Society for the Regulation of Vivisection wanted better regulation subjected to surveillance, not full prohibition. [21] [22] The Research Defence Society made up of an all-male group of physiologists was founded in 1908 to defend vivisection. [23] In the 1920s, anti-vivisectionists exerted significant influence over the editorial decisions of medical journals. [21]
It is possible that human vivisection was practised by some Greek anatomists in Alexandria in the 3rd century BCE. Celsus in De Medicina states that Herophilos of Alexandria vivisected some criminals sent by the king. The early Christian writer Tertullian states that Herophilos vivisected at least 600 live prisoners, although the accuracy of this claim is disputed by many historians. [24]
In the 12th century CE, Andalusian Arab Ibn Tufail elaborated on human vivisection in his treatise called Hayy ibn Yaqzan. In an extensive article on the subject, Iranian academic Nadia Maftouni believes him to be among the early supporters of autopsy and vivisection. [25]
Unit 731, a biological and chemical warfare research and development unit of the Imperial Japanese Army, undertook lethal human experimentation during the period that comprised both the Second Sino-Japanese War and the Second World War (1937–1945). In the Filipino island of Mindanao, Moro Muslim prisoners of war were subjected to various forms of vivisection by the Japanese, in many cases without anesthesia. [8] [26]
Nazi human experimentation involved many medical experiments on live subjects, such as vivisections by Josef Mengele, [27] usually without anesthesia. [28]
Animal testing, also known as animal experimentation, animal research, and in vivo testing, is the use of non-human animals, such as model organisms, in experiments that seek to control the variables that affect the behavior or biological system under study. This approach can be contrasted with field studies in which animals are observed in their natural environments or habitats. Experimental research with animals is usually conducted in universities, medical schools, pharmaceutical companies, defense establishments, and commercial facilities that provide animal-testing services to the industry. The focus of animal testing varies on a continuum from pure research, focusing on developing fundamental knowledge of an organism, to applied research, which may focus on answering some questions of great practical importance, such as finding a cure for a disease. Examples of applied research include testing disease treatments, breeding, defense research, and toxicology, including cosmetics testing. In education, animal testing is sometimes a component of biology or psychology courses.
In the animal rights movement, cruelty-free is a label for products or activities that do not harm or kill animals anywhere in the world. Products tested on animals or made from animals are not considered cruelty-free, since these tests are often painful and cause the suffering and death of millions of animals every year.
Cruelty Free International is a British animal rights and advocacy group that campaigns for the abolition of all animal testing. It organises certification of cruelty-free products which are marked with the symbol of a leaping bunny.
François Magendie was a French physiologist, considered a pioneer of experimental physiology. He is known for describing the foramen of Magendie. There is also a Magendie sign, a downward and inward rotation of the eye due to a lesion in the cerebellum. Magendie was a faculty at the College of France, holding the Chair of Medicine from 1830 to 1855.
Sir David Ferrier FRS was a pioneering Scottish neurologist and psychologist. Ferrier conducted experiments on the brains of animals such as monkeys and in 1881 became the first scientist to be prosecuted under the Cruelty to Animals Act, 1876 which had been enacted following a major public debate over vivisection.
The People's Petition was an online campaign to express support for medical experimentation using animals in the United Kingdom. Within a year of launch the number of signatures exceeded 21,850 and included Tony Blair, the then-serving Prime Minister.
Gillian Rose Langley is a British scientist and writer who specialises in alternatives to animal testing and animal rights. She was, from 1981 until 2009, the science director of the Dr Hadwen Trust for Humane Research, a medical research charity developing non-animal research techniques. She was an anti-vivisection member of the British government's Animal Procedures Committee for eight years, and has worked as a consultant on non-animal techniques for the European Commission, and for animal protection organizations in Europe and the United States. Between 2010 and 2016 she was a consultant for Humane Society International.
The National Anti-Vivisection Society (NAVS) is an international non-profit animal protection group, based in London, working to end animal testing, and focused on the replacement of animals in research with advanced, scientific techniques. Since 2006, the NAVS has operated its international campaigns under the working name Animal Defenders International (ADI), and the two groups now work together under the ADI name.
The history of animal testing goes back to the writings of the Ancient Greeks in the 4th and 3rd centuries BCE, with Aristotle and Erasistratus one of the first documented to perform experiments on nonhuman animals. Galen, a physician in 2nd-century Rome, dissected pigs and goats, and is known as the "Father of Vivisection." Avenzoar, an Arabic physician in 12th-century Moorish Spain who also practiced dissection, introduced animal testing as an experimental method of testing surgical procedures before applying them to human patients. Although the exact purpose of the procedure was unclear, a Neolithic surgeon performed trepanation on a cow in 3400-3000 BCE. This is the earliest known surgery to have been performed on an animal, and it is possible that the procedure was done on a dead cow in order for the surgeon to practice their skills.
The Boyd Group is a Britain-based, independent think tank considering issues relating to animal testing.
The Brown Dog affair was a political controversy about vivisection that raged in Britain from 1903 until 1910. It involved the infiltration of University of London medical lectures by Swedish feminists, battles between medical students and the police, police protection for the statue of a dog, a libel trial at the Royal Courts of Justice, and the establishment of a Royal Commission to investigate the use of animals in experiments. The affair became a cause célèbre that divided the country.
The Cruelty to Animals Act 1876 was an Act of the Parliament of the United Kingdom which set limits on the practice of, and instituted a licensing system for animal experimentation, amending the Cruelty to Animals Act 1849. It was a public general Act. The Act was replaced 110 years later by the Animals Act 1986.
Animal ethics is a branch of ethics which examines human-animal relationships, the moral consideration of animals and how nonhuman animals ought to be treated. The subject matter includes animal rights, animal welfare, animal law, speciesism, animal cognition, wildlife conservation, wild animal suffering, the moral status of nonhuman animals, the concept of nonhuman personhood, human exceptionalism, the history of animal use, and theories of justice. Several different theoretical approaches have been proposed to examine this field, in accordance with the different theories currently defended in moral and political philosophy. There is no theory which is completely accepted due to the differing understandings of what is meant by the term ethics; however, there are theories that are more widely accepted by society such as animal rights and utilitarianism.
Women have played a central role in animal advocacy since the 19th century. The animal advocacy movement – embracing animal rights, animal welfare, and anti-vivisectionism – has been disproportionately initiated and led by women, particularly in the United Kingdom. Women are more likely to support animal rights than men. A 1996 study of adolescents by Linda Pifer suggested that factors that may partially explain this discrepancy include attitudes towards feminism and science, scientific literacy, and the presence of a greater emphasis on "nurturance or compassion" amongst women. Although vegetarianism does not necessarily imply animal advocacy, a 1992 market research study conducted by the Yankelovich research organization concluded that "of the 12.4 million people [in the US] who call themselves vegetarian, 68% are female, while only 32% are male".
The concept of moral rights for animals is believed to date as far back as Ancient India, particularly early Jainist and Hindu history. What follows is mainly the history of animal rights in the Western world. There is a rich history of animal protection in the ancient texts, lives, and stories of Eastern, African, and Indigenous peoples.
The American Anti-Vivisection Society (AAVS) is a Jenkintown, Pennsylvania-based animal protectionism organization created with the goal of eliminating a number of different procedures done by medical and cosmetic groups in relation to animal cruelty in the United States. It seeks to help the betterment of animal life and human-animal interaction through legislation reform. It was the first anti-vivisection organization founded in the United States.
In anatomy and neurophysiology, this is the finding that the anterior spinal nerve roots contain only motor fibers and posterior roots only sensory fibers and that nerve impulses are conducted in only one direction in each case. The nature and the physiology of the phenomena were described independently by the British anatomical scientist Sir Charles Bell and the French physiologist François Magendie, later confirmed by the German physiologist Johannes Peter Müller.
Marie Françoise "Fanny" Bernard was a French anti-vivisection campaigner and creator of an anti-vivisection society. She was the wife of the pioneer in experimental research in physiology, Claude Bernard.
Rise for Animals is a national, registered 501(c)(3) nonprofit animal rights organization which aims to end nonhuman animal experimentation. It has been described as "one of the oldest and wealthiest anti-vivisection organizations in the United States".
Animal welfare and rights in India regards the treatment of and laws concerning non-human animals in India. It is distinct from animal conservation in India.
Operation on a living animal for experimental rather than healing purposes; more broadly, all experimentation on live animals.
practices, equally cruel, with which he thought the legislature ought to interfere. There was a Frenchman by the name of Magendie, whom he considered a disgrace to Society. In the course of the last year this man, at one of his anatomical theatres, exhibited a series of experiments so atrocious as almost to shock belief. This M. Magendie got a lady's greyhound. First of all he nailed its front, and then its hind, paws with the bluntest spikes that he could find, giving as reason that the poor beast, in its agony, might tear away from the spikes if they were at all sharp or cutting. He then doubled up its long ears, and nailed them down with similar spikes. (Cries of `Shame!') He then made a gash down the middle of the face, and proceeded to dissect all the nerves on one side of it.... After he had finished these operations, this surgical butcher then turned to the spectators, and said: `I have now finished my operations on one side of this dog's head, and I shall reserve the other side till to-morrow. If the servant takes care of him for the night, I am of the opinion that I shall be able to continue my operations upon him to-morrow with as much satisfaction to us all as I have done to-day; but if not, ALTHOUGH HE MAY HAVE LOST THE VIVACITY HE HAS SHOWN TO-DAY, I shall have the opportunity of cutting him up alive, and showing you the motion of the heart.' Mr. Martin added that he held in his hands the written declarations of Mr. Abernethy, of Sir Everard Home (and of other distinguished medical men), all uniting in condemnation of such excessive and protracted cruelty as had been practised by this Frenchman." {1} Hansard's Parliamentary Reports, February 24, 1825.
Another witness of Magendie's cruelty was Dr. William Sharpey, LL.D., Fellow of the Royal Society, and for more than thirty years the professor of physiology in University College, London. ... Before the Royal Commission on Vivisection, in 1876, he gave the following account of his personal experience: "When I was a very young man, studying in Paris, I went to the first of a series of lectures which Magendie gave upon experimental physiology; and I was so utterly repelled by what I witnessed that I never went again. In the first place, they were painful (in those days there were no anaesthetics), and sometimes they were severe; and then THEY WERE WITHOUT SUFFICIENT OBJECT. For example, Magendie made incisions into the skin of rabbits and other creatures TO SHOW THAT THE SKIN IS SENSITIVE! Surely all the world knows the skin is sensitive; no experiment is wanted to prove that. Several experiments he made were of a similar character, AND HE PUT THE ANIMALS TO DEATH, FINALLY, IN A VERY PAINFUL WAY.... Some of his experiments excited a strong feeling of abhorrence, not in the public merely, but among physiologists. There was his--I was going to say `famous' experiment; it might rather have been called `INFAMOUS' experiment upon vomiting .... Besides its atrocity, it was really purposeless."
