Leirás Besorolás: Óvszer Felhasználási év: Gumi: 1855Latex: 1920Polyurethane: 1994 Terhességi arány (az első évben, latex) Megfelelő használat esetén: 2% Általános használat esetén: 10–18% A termék Emlékeztető Latex alapú kondom, olaj alapú lubricants Előnyök és hátrányok STD védelem Igen Egyéb Orvosi vagy klinikai vizsgálat nem szükséges A condom (kiejtve /ˈkɒndəm/ (US) vagy /ˈkɒndɒm/ (UK)) egy olyan fogamzásgátló eszköz, amely csökkenti a terhesség veszélyét,, valamint olyan nemi betegségek veszélyének előfordulását, mint pl a nemi úton terjedő betegségek (STDs—mint a gonorrhea, syphilis, és a HIV). Ezt az óvszert a férfi merev hímvesszőjére húzva megakadályozható, hogy az ondó a partner testébe hatoljon. Mivel a kondomok vízhatlanok, rugalmas és tartós anyagból készülnek, emiatt széles körben terjedt el másodlagos használatuk. Többek között nem-sexuális felhasználási területeken is alkalmazzák, mint pl vízhatlan mikrofonoknál, vagy hogy megóvják a puskacsövet az eltömődésektől. Napjainkban a kondomok már latexből készülnek, de voltak idők amikor poliuretánból, polyisoprene-ből, orvagy báránybélből. A női kondomok anyaga leggyakrabban poliuretán. A születésszabályozást szem előtt tartva a férfi óvszerek ma már olcsó terméknek minősülnek, könnyen használhatóak, és e mellett mellékhatásuk alig van, miközben nagyon jó védelmet biztosítanak a nemi betegségek ellen. Megfelelő alkalmazás esetén azon pároknál, akinél a férfi óvszert használt, évi 2% volt a terhességi arány.

A De Morbo Gallico(A Francia-szindróma) egy oldala Gabriele Falloppio tollából, ahol a vérbajról tesz említést. A művet 1564-ben adták ki, ebben szerepel elősször a kondomok használata. Fő műve: Az óvszerek története

A 19 század előtt

Az ősi Egyiptomban, Görögországban és Rómában a nö felelőssége volt a terhesség elleni védelem, és emiatt csak a női megoldások voltak igazán megfelelőek, a leírások alapján. [1]:17,23 A tizenötödik század előtti Ázsiában csak a glans˙(olyan eszköz, mely csak a pénisz fejét fedi) kondomokról van feljegyzés. A leírások alapján fogamzásgátlásra használhatták őket, és csak a felső társadalmi osztály számára volt elérhető. Kinában a glans kondomok olajozott selyempapírból vagy báránybélből készülhettek. Japánban teknősbékahéjból, vagy állatszarvból. [1]:60-1

Gabriele Falloppio a 16. században a értekezést írt a szifiliszről. Az első dokumnetált eset 1490-ben történt, egy olyan járvány, ami sok mellékhatással együtt járva hónapok alatt elvitte a szerencsétlen pácienst.[2][3] Idekívánkozik Falloppio értekezése a legkorábbi vitathatatlan kondomhasználatról: a leírás vegyi folyadékba áztatott vászonkondomról tesz említtést, melyet kiszáradás után lehetett használni. Ezt a vászondarabot a pénisz fejére tették, és szalaggal rögzítették. [1]:51,54-5[4] Falloppio állítása szerint, ez egy kísérleti védelem volt a szifilisz ellen. [5]


Egy állati bőrből készült kondom A 18. századra a kondompiac gyor fejlődésnek indult, többféle méretben és minőségben lettek elérhetőek, készültek bőrből és vászonból árulták kocsmáknál, boltokban és piacokon egész Európában és Oroszországban. .[1]:90-2,97,104

Az 1800-as évektől 1920-ig A kora 19. századi fogamzásgátlás először a szegényebb osztályokban volt megfigyelhető. Az írások a fogamzásgátlás alternatív módjáról szóltak. Ezen korszak feministái a saját kezükbe szerették volna tudni a születésszabályozás megoldását, és helytelenítették, hogy a hímek a kondomot használják. [1]:129,152- Más források a kondomok árát sokallták, és megbízhatatlannak ítélték, de végül is egyetértettek abban, hogy ez az egyedüli jó megoldás a nem kívánt terhesség, és a betegségek ellen. [1]:88,90,125,129-30 Sok ország törvénnyel tiltotta az óvszerek gyártását, ezzel szemben hirdette a női fogazásgátló tablettákat. [1]:144,163-4,168-71, Leirások szóltak arról, hogyan készítsenek saját otthonukban óvszereket, amit Európában és az Államokban osztogattak.[1]:126,136 A társadalmi és törvényes ellenzék ellenére a tizenkilencedik század végén a kondom vált a világ legnépszerűbb születésszabályozás módszerévé a nyugati világban. [1]:173-4


Egy absztinenciát támogató plakát

A tizenkilencedik század második felére a nemi úton terjedő betegségek arányai az egekbe szöktek Amerikában. Okai a történészek szerint elsődlegesen az Amerikai Polgárháborúra vezethetőek vissza, illetve a megelőző módszerek ismereteinek hiánya, melyet a Comstocki törvények jelentettek.[1]:137-8,159 Hogy felvegyék a harcot a járvánnyal szemben, sexuális felvilágosítást vezettek be egyes magániskolákban, a betegségekről és azok terjedéséről. A kondomokat nem javasolták, mert az orvosi közösség és az erkölcscsőszök szerint az STD a büntetése az erkölcstelen sexuális viselkedésnek. A megbélyegzés ezekkel az áldozatokkal szemben olyan nagy volt, hogy sok kórház megtagadta azon páciensek kezelését, akinél vérbajt állapítottak meg. [1]:176 Sigmund Freud, a pszichoanalízis alapítója mereven ellenzett minden születésszabályozási módszert, mert a hibaszázalékokat túl magasnak ítélte. 1920-ban az Angol egyház Lambeth Konferenciája elítélte a ’születésszabályozás mindenemű eszközét. Mindettől függetlenül 1920-ra világszerte az óvszerek eladása megduplázódott.


Rubber and manufacturing advances The rubber vulcanization process was patented by Charles Goodyear in 1844.[6] The first rubber condom was produced in 1855.[7] For many decades, rubber condoms were manufactured by wrapping strips of raw rubber around penis-shaped molds, then dipping the wrapped molds in a chemical solution to cure the rubber.[1]:148 In 1912, a German named Julius Fromm developed a new, improved manufacturing technique for condoms: dipping glass molds into a raw rubber solution.[7] Called cement dipping, this method required adding gasoline or benzene to the rubber to make it liquid.[1]:200 Latex, rubber suspended in water, was invented in 1920. Latex condoms required less labor to produce than cement-dipped rubber condoms, which had to be smoothed by rubbing and trimming. The use of water to suspend the rubber instead of gasoline and benzene eliminated the fire hazard previously associated with all condom factories. Latex condoms also performed better for the consumer: they were stronger and thinner than rubber condoms, and had a shelf life of five years (compared to three months for rubber).[1]:199-200 Until the twenties, all condoms were individually hand-dipped by semiskilled workers. Throughout the decade of the 1920s, advances in the automation of the condom assembly line were made. The first fully automated line was patented in 1930. Major condom manufacturers bought or leased conveyor systems, and small manufacturers were driven out of business.[1]:201-3 The skin condom, now significantly more expensive than the latex variety, became restricted to a niche high-end market.[1]:220 1930 to present In 1930 the Anglican Church's Lambeth Conference sanctioned the use of birth control by married couples. In 1931 the Federal Council of Churches in the U.S. issued a similar statement.[1]:227 The Roman Catholic Church responded by issuing the encyclical Casti Connubii affirming its opposition to all contraceptives, a stance it has never reversed.[1]:228-9 In the 1930s, legal restrictions on condoms began to be relaxed.[1]:216,226,234[8] But during this period Fascist Italy and Nazi Germany increased restrictions on condoms (limited sales as disease preventatives were still allowed).[1]:252,254-5 During the Depression, condom lines by Schmid gained in popularity. Schmid still used the cement-dipping method of manufacture which had two advantages over the latex variety. Firstly, cement-dipped condoms could be safely used with oil-based lubricants. Secondly, while less comfortable, these older-style rubber condoms could be reused and so were more economical, a valued feature in hard times.[1]:217-9 More attention was brought to quality issues in the 1930s, and the U.S. Food and Drug Administration began to regulate the quality of condoms sold in the United States.[1]:223-5 Throughout World War II, condoms were not only distributed to male U.S. military members, but also heavily promoted with films, posters, and lectures.[1]:236-8,259 European and Asian militaries on both sides of the conflict also provided condoms to their troops throughout the war, even Germany which outlawed all civilian use of condoms in 1941.[1]:252-4,257-8 In part because condoms were readily available, soldiers found a number of non-sexual uses for the devices, many of which continue to this day. After the war, condom sales continued to grow. From 1955–1965, 42% of Americans of reproductive age relied on condoms for birth control. In Britain from 1950–1960, 60% of married couples used condoms. The birth control pill became the world's most popular method of birth control in the years after its 1960 début, but condoms remained a strong second. The U.S. Agency for International Development pushed condom use in developing countries to help solve the "world population crises": by 1970 hundreds of millions of condoms were being used each year in India alone.[1]:267-9,272-5 (This number has grown in recent decades: in 2004, the government of India purchased 1.9 billion condoms for distribution at family planning clinics.)[9] In the 1960s and 1970s quality regulations tightened,[10] and more legal barriers to condom use were removed.[1]:276-9 In Ireland, legal condom sales were allowed for the first time in 1978.[1]:329-30 Advertising, however was one area that continued to have legal restrictions. In the late 1950s, the American National Association of Broadcasters banned condom advertisements from national television: this policy remained in place until 1979.[1]:273-4,285 After learning in the early 1980s that AIDS can be a sexually transmitted infection,[11] the use of condoms was encouraged to prevent transmission of HIV. Despite opposition by some political, religious, and other figures, national condom promotion campaigns occurred in the U.S. and Europe.[1]:299,301,306-7,312-8 These campaigns increased condom use significantly.[1]:309-17 Due to increased demand and greater social acceptance, condoms began to be sold in a wider variety of retail outlets, including in supermarkets and in discount department stores such as Wal-Mart.[1]:305 Condom sales increased every year until 1994, when media attention to the AIDS pandemic began to decline.[1]:303-4 The phenomenon of decreasing use of condoms as disease preventatives has been called prevention fatigue or condom fatigue. Observers have cited condom fatigue in both Europe and North America.[12][13] As one response, manufacturers have changed the tone of their advertisements from scary to humorous.[1]:303-4 New developments continue to occur in the condom market, with the first polyurethane condom—branded Avanti and produced by the manufacturer of Durex—introduced in the 1990s,[1]:324-5 and the first custom sized-to-fit condom, called TheyFit, introduced in 2003.[14] Worldwide condom use is expected to continue to grow: one study predicted that developing nations would need 18.6 billion condoms in 2015.[1]:342 Condoms have become an integral part of modern societies. Etymology and other terms The term condom first appears in the early 18th century. Its etymology is unknown. In popular tradition, the invention and naming of the condom came to be attributed to an associate of England's King Charles II, one "Dr. Condom" or "Earl of Condom". There is however no evidence of the existence of such a person, and condoms had been used for over one hundred years before King Charles II ascended to the throne.[1]:54,68 A variety of Latin etymologies have been proposed, including condon (receptacle),[15] condamina (house),[16] and cumdum (scabbard or case).[1]:70-1 It has also been speculated to be from the Italian word guantone, derived from guanto, meaning glove.[17] William E. Kruck wrote an article in 1981 concluding that, "As for the word 'condom', I need state only that its origin remains completely unknown, and there ends this search for an etymology."[18] Modern dictionaries may also list the etymology as "unknown".[19] Other terms are also commonly used to describe condoms. In North America condoms are also commonly known as prophylactics, or rubbers. In Britain they may be called French letters.[20] Additionally, condoms may be referred to using the manufacturer's name. Varieties Most condoms have a reservoir tip or teat end, making it easier to accommodate the man's ejaculate. Condoms come in different sizes, from oversized to snug and they also come in a variety of surfaces intended to stimulate the user's partner. Condoms are usually supplied with a lubricant coating to facilitate penetration, while flavored condoms are principally used for oral sex. As mentioned above, most condoms are made of latex, but polyurethane and lambskin condoms are also widely available. Materials Natural latex


An unrolled latex condom Latex has outstanding elastic properties: Its tensile strength exceeds 30 MPa, and latex condoms may be stretched in excess of 800% before breaking.[21] In 1990 the ISO set standards for condom production (ISO 4074, Natural latex rubber condoms), and the EU followed suit with its CEN standard (Directive 93/42/EEC concerning medical devices). Every latex condom is tested for holes with an electrical current. If the condom passes, it is rolled and packaged. In addition, a portion of each batch of condoms is subject to water leak and air burst testing.[22] While the advantages of latex have made it the most popular condom material, it does have some drawbacks. Latex condoms used with oil-based lubricants such as petroleum jelly are likely to break or slip off due to loss of elasticity caused by the oils.[23] Additionally, latex allergy precludes use of latex condoms and is one of the principal reasons for the use of other materials. In May 2009 the U.S. Food and Drug Administration granted approval for the production of condoms composed of Vytex,[24] latex that has been treated to remove 90% of the proteins responsible for allergic reactions.[25] An allergen-free condom made of synthetic latex (polyisoprene) is also available.[26] Synthetic The most common non-latex condoms are made from polyurethane. Condoms may also be made from other synthetic materials, such as AT-10 resin, and most recently polyisoprene.[26] Polyurethane condoms tend to be the same width and thickness as latex condoms, with most polyurethane condoms between 0.04 mm and 0.07 mm thick.[27] Polyurethane is also the material of many female condoms. Polyurethane can be considered better than latex in several ways: it conducts heat better than latex, is not as sensitive to temperature and ultraviolet light (and so has less rigid storage requirements and a longer shelf life), can be used with oil-based lubricants, is less allergenic than latex, and does not have an odor.[28] Polyurethane condoms have gained FDA approval for sale in the United States as an effective method of contraception and HIV prevention, and under laboratory conditions have been shown to be just as effective as latex for these purposes.[29] However, polyurethane condoms are less elastic than latex ones, and may be more likely to slip or break than latex,[28][30] and are more expensive. Polyisoprene is a synthetic version of natural rubber latex. While significantly more expensive,[31] it has the advantages of latex (such as being softer and more elastic than polyurethane condoms)[26] without the protein which is responsible for latex allergies.[31] Lambskin Condoms made from sheep intestines, labeled "lambskin", are also available. They provide more sensation and are less allergenic than latex. However, there is an increased risk of transmitting STDs compared to latex because of pores in the material, which are thought to be large enough to allow infectious agents to pass through, albeit blocking the passage of sperm.[32] Lambskin condoms are also significantly more expensive than other types. Spermicidal Some latex condoms are lubricated at the manufacturer with a small amount of a nonoxynol-9, a spermicidal chemical. According to Consumer Reports, condoms lubricated with spermicide have no additional benefit in preventing pregnancy, have a shorter shelf life, and may cause urinary-tract infections in women.[33] In contrast, application of separately packaged spermicide is believed to increase the contraceptive efficacy of condoms.[34] Nonoxynol-9 was once believed to offer additional protection against STDs (including HIV) but recent studies have shown that, with frequent use, nonoxynol-9 may increase the risk of HIV transmission.[35] The World Health Organization says that spermicidally lubricated condoms should no longer be promoted. However, it recommends using a nonoxynol-9 lubricated condom over no condom at all.[36] As of 2005, nine condom manufacturers have stopped manufacturing condoms with nonoxynol-9 and Planned Parenthood has discontinued the distribution of condoms so lubricated.[37] Textured Textured condoms include studded and ribbed condoms which can provide extra sensations to both partners. The studs or ribs can be located on the inside, outside, or both; alternatively, they are located in specific sections to provide directed stimulation to either the g-spot or perineum. Many textured condoms which advertise "mutual pleasure" also are bulb-shaped at the top, to provide extra stimulation to the male.[38] Studded condoms should be avoided with anal intercourse as they can irritate and possibly tear the walls of the anus. Some women experience irritation during vaginal intercourse with studded condoms. Other


Female condom See also: Female condom A female version of the condom has been available since 1988. Female condoms were initially all made of polyurethane, but newer versions may be made of nitrile or latex.[39] The anti-rape condom is another variation designed to be worn by women. It is designed to cause pain to the attacker, hopefully allowing the victim a chance to escape.[40] A collection condom is used to collect semen for fertility treatments or sperm analysis. These condoms are designed to maximize sperm life. Some condom-like devices are intended for entertainment only, such novelty condoms may not provide protection against pregnancy and STDs.[41] Effectiveness In preventing pregnancy See also: Comparison of birth control methods#Effectiveness of various methods The effectiveness of condoms, as of most forms of contraception, can be assessed two ways. Perfect use or method effectiveness rates only include people who use condoms properly and consistently. Actual use, or typical use effectiveness rates are of all condom users, including those who use condoms incorrectly or do not use condoms at every act of intercourse. Rates are generally presented for the first year of use.[42] Most commonly the Pearl Index is used to calculate effectiveness rates, but some studies use decrement tables.[43]:141 The typical use pregnancy rate among condom users varies depending on the population being studied, ranging from 10–18% per year.[44] The perfect use pregnancy rate of condoms is 2% per year.[42] Condoms may be combined with other forms of contraception (such as spermicide) for greater protection.[34] In preventing STDs


A giant condom on the Obelisk of Buenos Aires, Argentina, part of an awareness campaign for the 2005 World AIDS Day See also: Safe sex Condoms are widely recommended for the prevention of sexually transmitted diseases (STDs). They have been shown to be effective in reducing infection rates in both men and women. While not perfect, the condom is effective at reducing the transmission of organisms that cause AIDS, genital herpes, cervical cancer, genital warts, syphilis, chlamydia, gonorrhea, and other diseases.[41] Condoms are often recommended as an adjunct to more effective birth control methods (such as IUD) in situations where STD protection is also desired.[45] According to a 2000 report by the National Institutes of Health (NIH), correct and consistent use of latex condoms reduces the risk of HIV/AIDS transmission by approximately 85% relative to risk when unprotected, putting the seroconversion rate (infection rate) at 0.9 per 100 person-years with condom, down from 6.7 per 100 person-years.[46] Analysis published in 2007 from the University of Texas Medical Branch [47] and the World Health Organization[48] found similar risk reductions of 80–95%. The 2000 NIH review concluded that condom use significantly reduces the risk of gonorrhea for men.[46] A 2006 study reports that proper condom use decreases the risk of transmission of human papillomavirus to women by approximately 70%.[49] Another study in the same year found consistent condom use was effective at reducing transmission of herpes simplex virus-2 also known as genital herpes, in both men and women.[50] Although a condom is effective in limiting exposure, some disease transmission may occur even with a condom. Infectious areas of the genitals, especially when symptoms are present, may not be covered by a condom, and as a result, some diseases can be transmitted by direct contact.[51] The primary effectiveness issue with using condoms to prevent STDs, however, is inconsistent use.[22] Condoms may also be useful in treating potentially precancerous cervical changes. Exposure to human papillomavirus, even in individuals already infected with the virus, appears to increase the risk of precancerous changes. The use of condoms helps promote regression of these changes.[52] In addition, researchers in the UK suggest that a hormone in semen can aggravate existing cervical cancer, condom use during sex can prevent exposure to the hormone.[53] Causes of failure 

	The Wikibook Sexual Health has a page on the topic of Barrier Birth Control and Spermicide

Condoms may slip off the penis after ejaculation,[54] break due to improper application or physical damage (such as tears caused when opening the package), or break or slip due to latex degradation (typically from usage past the expiration date, improper storage, or exposure to oils). The rate of breakage is between 0.4% and 2.3%, while the rate of slippage is between 0.6% and 1.3%.[46] Even if no breakage or slippage is observed, 1–2% of women will test positive for semen residue after intercourse with a condom.[55][56] "Double bagging," using two condoms at once, also increases the risk of condom failure.[57][58] Different modes of condom failure result in different levels of semen exposure. If a failure occurs during application, the damaged condom may be disposed of and a new condom applied before intercourse begins — such failures generally pose no risk to the user.[59] One study found that semen exposure from a broken condom was about half that of unprotected intercourse; semen exposure from a slipped condom was about one-fifth that of unprotected intercourse.[60] Standard condoms will fit almost any penis, although many condom manufacturers offer "snug" or "magnum" sizes. Some manufacturers also offer custom sized-to-fit condoms, with claims that they are more reliable and offer improved sensation/comfort.[14][61][62] Some studies have associated larger penises and smaller condoms with increased breakage and decreased slippage rates (and vice versa), but other studies have been inconclusive.[23] Condom thickness is not associated with condom breakage, thinner condoms are as effective as thicker ones.[63] Nevertheless, it is recommended for condoms manufactures to avoid very thick, or very thin condoms, because they are both considered less effective.[64] Some authors even encourage users to choose thinner condoms "for greater durability, sensation, and comfort"[65], but others warn that "the thinner the condom, the smaller the force required to break it".[66] Experienced condom users are significantly less likely to have a condom slip or break compared to first-time users, although users who experience one slippage or breakage are more likely to suffer a second such failure.[67] An article in Population Reports suggests that education on condom use reduces behaviors that increase the risk of breakage and slippage.[68] A Family Health International publication also offers the view that education can reduce the risk of breakage and slippage, but emphasizes that more research needs to be done to determine all of the causes of breakage and slippage.[23] Among people who intend condoms to be their form of birth control, pregnancy may occur when the user has sex without a condom. The person may have run out of condoms, or be traveling and not have a condom with them, or simply dislike the feel of condoms and decide to "take a chance." This type of behavior is the primary cause of typical use failure (as opposed to method or perfect use failure).[69] Another possible cause of condom failure is sabotage. One motive is to have a child against a partner's wishes or consent.[70] Some commercial sex workers from Nigeria reported clients sabotaging condoms in retaliation for being coerced into condom use.[71] Using a fine needle to make several pinholes at the tip of the condom is believed to significantly impact their effectiveness.[43]:306-307[56] Prevalence The prevalence of condom use varies greatly between countries. Most surveys of contraceptive use are among married women, or women in informal unions. Japan has the highest rate of condom usage in the world: in that country, condoms account for almost 80% of contraceptive use by married women. On average, in developed countries, condoms are the most popular method of birth control: 28% of married contraceptive users rely on condoms. In the average less-developed country, condoms are less common: only 6-8% of married contraceptive users choose condoms.[72] Condom use for disease prevention also varies. Among gay men in the United States, one survey found that 35% had used two condoms at the same time, a practice called "double bagging".[73] While intended to provide extra protection, double bagging actually increases the risk of condom failure. Use


How to put on a condom Male condoms are usually packaged inside a foil wrapper, in a rolled-up form, and are designed to be applied to the tip of the penis and then unrolled over the erect penis. It is important that some space be left in the tip of the condom so that semen has a place to collect; otherwise it may be forced out of the base of the device. After use, it is recommended the condom be wrapped in tissue or tied in a knot, then disposed of in a trash receptacle.[74] Some couples find that putting on a condom interrupts sex, although others incorporate condom application as part of their foreplay. Some men and women find the physical barrier of a condom dulls sensation. Advantages of dulled sensation can include prolonged erection and delayed ejaculation; disadvantages might include a loss of some sexual excitement.[41] Advocates of condom use also cite their advantages of being inexpensive, easy to use, and having few side effects.[41][75] Role in sex education Condoms are often used in sex education programs, because they have the capability to reduce the chances of pregnancy and the spread of some sexually transmitted diseases when used correctly. A recent American Psychological Association (APA) press release supported the inclusion of information about condoms in sex education, saying "comprehensive sexuality education programs... discuss the appropriate use of condoms", and "promote condom use for those who are sexually active."[76] In the United States, teaching about condoms in public schools is opposed by some religious organizations.[77] Planned Parenthood, which advocates family planning and sex education, argues that no studies have shown abstinence-only programs to result in delayed intercourse, and cites surveys showing that 75% of American parents want their children to receive comprehensive sexuality education including condom use.[78] Infertility treatment Common procedures in infertility treatment such as semen analysis and intrauterine insemination (IUI) require collection of semen samples. These are most commonly obtained through masturbation, but an alternative to masturbation is use of a special collection condom to collect semen during sexual intercourse. Collection condoms are made from silicone or polyurethane, as latex is somewhat harmful to sperm. Many men prefer collection condoms to masturbation, and some religions prohibit masturbation entirely. Also, compared with samples obtained from masturbation, semen samples from collection condoms have higher total sperm counts, sperm motility, and percentage of sperm with normal morphology. For this reason, they are believed to give more accurate results when used for semen analysis, and to improve the chances of pregnancy when used in procedures such as intracervical or intrauterine insemination.[79] Adherents of religions that prohibit contraception, such as Catholicism, may use collection condoms with holes pricked in them.[43]:306-307 Condom therapy is sometimes prescribed to infertile couples when the female has high levels of antisperm antibodies. The theory is that preventing exposure to her partner's semen will lower her level of antisperm antibodies, and thus increase her chances of pregnancy when condom therapy is discontinued. However, condom therapy has not been shown to increase subsequent pregnancy rates.[80] Other uses Condoms excel as multipurpose containers because they are waterproof, elastic, durable, and will not arouse suspicion if found. Ongoing military utilization begun during World War II includes: · Tying a non-lubricated condom over the muzzle of the rifle barrel in order to prevent barrel fouling by keeping out detritus.[81] · The OSS used condoms for a plethora of applications, from storing corrosive fuel additives and wire garrotes (with the T-handles removed) to holding the acid component of a self-destructing film canister, to finding use in improvised explosives.[82] · Navy SEALs have used doubled condoms, sealed with neoprene cement, to protect non-electric firing assemblies for underwater demolitions—leading to the term "Dual Waterproof Firing Assemblies."[83] Other uses of condoms include: · Covers for endovaginal ultrasound probes.[84] Covering the probe with a condom reduces the amount of blood and vaginal fluids that the technician must clean off between patients. · Condoms can be used to hold water in emergency survival situations.[85] · Condoms have also been used to smuggle cocaine, heroin, and other drugs across borders and into prisons by filling the condom with drugs, tying it in a knot and then either swallowing it or inserting it into the rectum. These methods are very dangerous and potentially lethal; if the condom breaks, the drugs inside become absorbed into the bloodstream and can cause an overdose.[86] · In Soviet gulags, condoms were used to smuggle alcohol into the camps by prisoners who worked outside during daylight. While outside, the prisoner would ingest an empty condom attached to a thin piece of rubber tubing, the end of which was wedged between his teeth. The smuggler would then use a syringe to fill the tubing and condom with up to three liters of raw alcohol, which the prisoner would then smuggle back into the camp. When back in the barracks, the other prisoners would suspend him upside down until all the spirit had been drained out. Aleksandr Solzhenitsyn records that the three liters of raw fluid would be diluted to make seven liters of crude vodka, and that although such prisoners risked an extremely painful and unpleasant death if the condom burst inside them, the rewards granted them by other prisoners encouraged them to run the risk.[87] · In his book entitled Last Chance to See, Douglas Adams reported having used a condom to protect a microphone he used to make an underwater recording. According to one of his traveling companions, this is standard BBC practice when a waterproof microphone is needed but cannot be procured.[88] · Condoms are used by engineers to keep soil samples dry during soil tests.[89] · Condoms are used in the field by engineers to initially protect sensors embedded in the steel or aluminum nose-cones of Cone Penetration Test (CPT) probes when entering the surface to conduct soil resistance tests to determine the bearing strength of soil.[90] · Condoms are used as a one-way valve by paramedics when performing a chest decompression in the field. The decompression needle is inserted through the condom, and inserted into the chest. The condom folds over the hub allowing air to exit the chest, but preventing it from entering.[91] Debate and criticism While condom use has many proven benefits, a few detractors—notably the Roman Catholic Church—believe condoms cause negative social effects that outweigh the protection they provide to individuals who use them. Some researchers have expressed concern over certain ingredients sometimes added to condoms, notably talc and nitrosamines. In addition, the large-scale use of disposable condoms has resulted in concerns over their environmental impact. Disposal and environmental impact


Used condom thrown on the street Experts, such as AVERT, recommend condoms be disposed of in a garbage receptacle, as flushing them down the toilet may cause plumbing blockages and other problems.[74][92] While biodegradable,[74] latex condoms damage the environment when disposed of improperly. According to the Ocean Conservancy, condoms, along with certain other types of trash, cover the coral reefs and smother sea grass and other bottom dwellers. The United States Environmental Protection Agency also has expressed concerns that many animals might mistake the litter for food.[93] Condoms made of polyurethane, a plastic material, do not break down at all. The plastic and foil wrappers condoms are packaged in are also not biodegradable. However, the benefits condoms offer are widely considered to offset their small landfill mass.[74] Frequent condom or wrapper disposal in public areas such as a parks have been seen as a persistent litter problem.[94] Position of the Roman Catholic Church See also: Catholic teachings on sexual morality#Use of condoms The Roman Catholic Church directly condemns any artificial birth control or sexual acts, aside from intercourse between married heterosexuals.[95] The use of condoms to combat STDs is not specifically addressed by Catholic doctrine, and is currently a topic of debate among theologians and high-ranking Catholic authorities. A few, such as Belgian Cardinal Godfried Danneels, believe the Catholic Church should actively support condoms used to prevent disease, especially serious diseases such as AIDS.[96] However, the majority view—including all statements from the Vatican—is that condom-promotion programs encourage promiscuity, thereby actually increasing STD transmission.[97][98] This view was most recently reiterated in 2009 by Pope Benedict XVI.[99] The Roman Catholic Church is the largest organized body of any world religion.[100] This church has hundreds of programs dedicated to fighting the AIDS epidemic in Africa,[101] but its opposition to condom use in these programs has been highly controversial.[102] Health issues Dry dusting powders are applied to latex condoms before packaging to prevent the condom from sticking to itself when rolled up. Previously, talc was used by most manufacturers, but cornstarch is currently the most popular dusting powder.[103] Talc is known to be toxic if it enters the abdominal cavity (i.e. via the vagina). Cornstarch is generally believed to be safe, however some researchers have raised concerns over its use.[103][104] Nitrosamines, which are potentially carcinogenic in humans,[105] are believed to be present in a substance used to improve elasticity in latex condoms.[106] A 2001 review stated that humans regularly receive 1,000 to 10,000 times greater nitrosamine exposure from food and tobacco than from condom use and concluded that the risk of cancer from condom use is very low.[107] However, a 2004 study in Germany detected nitrosamines in 29 out of 32 condom brands tested, and concluded that exposure from condoms might exceed the exposure from food by 1.5- to 3-fold.[106][108] Cultural factors Cultural attitudes toward gender, contraception, and sex affect condom use and perceptions about condoms around the world. In less-developed countries and among less-educated populations, misperceptions about how disease transmission and conception work may negatively affect the use of condoms. In cultures with more traditional gender roles, women may feel uncomfortable demanding that their partners use condoms. Latino immigrants in the United States often face barriers to condom use. A study on female HIV prevention published in the Journal of Sex Health Research asserts that Latino women often lack the attitudes needed to negotiate safe sex due to traditional gender-role norms in the Latino community, and may be afraid to bring up the subject of condom use with their partners. Women who participated in the study often reported that their male partners would be angry or possibly violent at the suggestion that they use condoms.[109] A similar phenomenon has been noted in a survey of low-income African-American women; the women in this study also reported a fear of violence at the suggestion that condoms be used.[110] A telephone survey conducted by Rand Corporation and Oregon State University and published in the Journal of Acquired Immune Deficiency Syndromes showed that belief in AIDS conspiracy theories among black men is linked to rates of condom use; as conspiracy beliefs grew, consistent condom use dropped. Female use of condoms was not similarly affected.[111] In Africa, condom promotion in some areas has been impeded by anti-condom campaigns by some Muslim[112] and Catholic clergy.[97] Some women in Africa believe that condoms are "for prostitutes" and that respectable women should not use them.[112] A few clergy even promote the idea that condoms are deliberately laced with HIV.[113] Among the Massai in Tanzania, condom use is hampered by an aversion to "wasting" sperm, which is given sociocultural importance beyond reproduction. Sperm is believed to be an "elixir" to women and to have beneficial health effects. Massai women believe that, after conceiving a child, they must have sexual intercourse repeatedly so that the additional sperm aids the child's development. Frequent condom use is also considered by some Massai to cause impotence.[114] In much of the Western world, the introduction of the pill in the 1960s was associated with a decline in condom use.[1]:267-9,272-5 In Japan, oral contraceptives were not approved for use until September 1999, and even then access was more restricted than in other industrialized nations.[115] Perhaps because of this restricted access to hormonal contraception, Japan has the highest rate of condom usage in the world: in 2008, 80% of contraceptive users relied on condoms.[72] Major manufacturers See also: History of condoms#Major manufacturers One analyst described the size of the condom market as something that "boggles the mind". Numerous small manufacturers, nonprofit groups, and government-run manufacturing plants exist around the world.[1]:322,328 Within the condom market, there are several major contributors, among them both for-profit businesses and philanthropic organizations. Most large manufacturers have ties to the business that reach back to the end of the 19th century. · Julius Schmid, Inc. was founded in 1882 and began the Sheik and Ramses brands of condoms.[1]:154-6 The London Rubber Company began manufacturing latex condoms in 1932, under the Durex brand.[1]:199,201,218 Both companies are now part of Seton Scholl Limited.[1]:327 · Youngs Rubber Company, founded by Merle Youngs in late nineteenth century America, introduced the Trojan line of condoms[1]:191 now owned by Church and Dwight.[1]:323-4 · Dunlop Rubber began manufacturing condoms in Australia in the 1890s. In 1905, Dunlop sold its condom-making equipment to one of its employees, Eric Ansell, who founded Ansell Rubber. In 1969, Ansell was sold back to Dunlop.[1]:327 In 1987, English business magnate Richard Branson contracted with Ansell to help in a campaign against HIV and AIDS. Ansell agreed to manufacture the Mates brand of condom, to be sold at little or no profit in order to encourage condom use. Branson soon sold the Mates brand to Ansell, with royalty payments made annually to the charity Virgin Unite.[1]:309,311[116] In addition to its Mates brand, Ansell currently manufactures Lifestyles for the U.S. market.[1]:333 · In 1934 the Kokusia Rubber Company was founded in Japan. It is now known as the Okamoto Rubber Manufacturing Company.[1]:257 · In 1970 Tim Black and Philip Harvey founded Population Planning Associates (now known as Adam & Eve). Population Planning Associates was a mail-order business that marketed condoms to American college students. Black and Harvey used the profits from their company to start a non-profit organization Population Services International,[1]:286-7,337-9 and Harvey later also founded another nonprofit company, DKT International, that annually sells millions of condoms at discounted rates in developing countries around the world.[1]:286-7,337-9 Research See also: Male contraceptive A spray-on condom made of latex is intended to be easier to apply and more successful in preventing the transmission of diseases. As of 2009, the spray-on condom was not going to market because the drying time could not be reduced below two to three minutes.[117][118][119] The Invisible Condom, developed at Université Laval in Québec, Canada, is a gel that hardens upon increased temperature after insertion into the vagina or rectum. In the lab, it has been shown to effectively block HIV and herpes simplex virus. The barrier breaks down and liquefies after several hours. As of 2005, the invisible condom is in the clinical trial phase, and has not yet been approved for use.[120] Also developed in 2005 is a condom treated with an erectogenic compound. The drug-treated condom is intended to help the wearer maintain his erection, which should also help reduce slippage. If approved, the condom would be marketed under the Durex brand. As of 2007, it was still in clinical trials.[1]:345 References 1. ^ a b c d e f g h i j k l m n o p q r s t u v w x y z aa ab ac ad ae af ag ah ai aj ak al am an ao ap aq ar as at au av aw ax ay az ba bb bc bd be bf bg bh bi bj bk bl bm bn bo bp bq br Collier, Aine (2007).
