Reasons for<unk> <unk>  bodies vary wildly, but in most cases they are of sexual or criminal motivation. The<unk> <unk>  was inserted voluntarily in the vast majority of cases. This especially includes sexually motivated behaviour, encompassing the majority of cases.<unk> packing, i.e. illegal transport of drugs within a<unk>  orifice (here: inside the rectum), is another – potentially – voluntary reason for insertion of<unk> <unk>  bodies. This includes attempts to transport objects like weapons, including knives, or ammunition. According to one study, sexual stimulation was responsible for 80% of clinically relevant<unk> <unk>  bodies. About 10% of the cases were due to sexual assault. In rare cases, the patient inserted the object into the rectum without a way to remove it intending to receive attention and pity from doctors and nurses. This behaviour is categorized as Munchausen's syndrome. Another cause may be attempted self-treatment of diseases. One patient attempted to treat his chronic diarrhea by inserting an ear of maize into his rectum. Another patient tried to soothe the itching due to his hemorrhoids (Pruritus ani) with a toothbrush. The toothbrush went out of control and disappeared inside his anus. Accidents or torture may cause an involuntary insertion of a<unk> <unk> . A mercury medical thermometer inserted into the anus in order to measure the temperature, but broke off while inside, is an example of a<unk> <unk> <unk>  due to an accident. Ancient Greece knew the Rhaphanidosis as a punishment for male adulterers. It involved the insertion of a radish into the anus. Many self-inserted<unk>  bodies are stated as accidentally by the patients due to feelings of shame. There are several reasons that contribute to the jamming of<unk>  bodies inside the rectum. Many of the objects used for sexual stimulation have a conical tip in order to facilitate penetration, while the base is flat. Extraction by the user may be impossible if the base of the object passed the anus towards the rectum. In order to receive a stronger stimulation, the object may be inserted deeper than intended. In this case, the sphincter prevents, by mechanical means, the extraction of the<unk> <unk> . By mouth The other way for a<unk> <unk>  to travel through the digestive system (after oral intake and passage through the entire intestines) happens very often, but is only rarely medically relevant. Other constrictions, such as the esophagus, cardia, pylorus or ileocecal valve tend to cause issues with other organs, provided a<unk> <unk>  is large enough to be an issue. Some<unk>  bodies may still pass those narrows and may cause medically relevant issues, i.e. toothpicks and bones. Bones especially, i.e. from chickens, cause about two thirds of all intestinal perforations. Plant-based food, especially seeds like popcorn, watermelon, sunflower and pumpkin seed, may clump together inside the lower intestines to form bezoars. Those may grow too big for normal anal passage, thus becoming clinically relevant. This kind of<unk>  happens chiefly in children, especially in Northern Africa and the Middle East, where those seeds form an elemental part of the diet. In very rare cases, seeds inside a bezoar may germinate inside the lower intestines or the rectum, causing a blockade. Objects Type and size of the<unk> <unk>  bodies are diverse and may exceed the anatomical-physiological imagination. Objects documented in literature include: * Razor, screw, screwdriver, small rolled tool bag (15×12 cm, including tools 620 g), hairpin, milk can opener, drill bit * Short staffs, such as a 27 cm long chair leg, a 19 cm long spade handle and a broken off broom handle, extension parts for a vacuum cleaner * Containers, sometimes exceeding 0.5 L in volume, e.g. sparkling wine bottles, bottles of Coca Cola, jam pots, small beer glasses, cups * Spray can, light bulb, vacuum tube, candle * WWII artillery shell requiring attention from a bomb squad * Table tennis ball, Boccia ball * Ammunition, firecracker * Vibrator, rubber rod, dildo * a toy car * spectacles, a suitcase key, a tobacco pouch and a magazine at the same time * plastic tooth brush case Not all objects are solid. In 1987, a case was documented of a patient who administered a cement enema. After it solidified and impacted, the resulting block had to be surgically extracted. Another extreme case occurred in November 1953. A depressed man inserted a 15 cm long cardboard tube into his rectum and tossed a lighted firecracker into the tube's opening, resulting in a large hole in his rectum.
