 A condom is a sheath @-@ shaped barrier device that may be used during sexual intercourse to reduce the probability of pregnancy and decrease the risk of sexually transmitted infections ( STIs ) such as HIV / AIDS . It is rolled onto an erect penis before intercourse and blocks <unk> semen from entering the body of a sexual partner . Condoms are also used during <unk> and for collection of semen for use in infertility treatment . In the modern age , condoms are most often made from latex , but some are made from other materials such as polyurethane , polyisoprene , or lamb intestine . A female condom is also available , often made of <unk> rubber . 
 As a method of birth control , male condoms have the advantages of being inexpensive , easy to use , having few side effects , and offering protection against sexually transmitted infections . With proper use — and use at every act of intercourse — women whose partners use male condoms experience a 2 % per @-@ year pregnancy rate . With typical use the rate of pregnancy is 18 % per @-@ year . Condoms have been used for at least 400 years . Since the 19th century , they have been one of the most popular methods of contraception in the world . While widely accepted in modern times , condoms have generated some controversy , primarily over what role they should play in sex education classes .

 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 . <unk> 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 . <unk> are generally presented for the first year of use . Most commonly the Pearl Index is used to calculate effectiveness rates , but some studies use <unk> tables . 
 The typical use pregnancy rate among condom users varies depending on the population being studied , ranging from 10 to 18 % per year . The perfect use pregnancy rate of condoms is 2 % per year . Condoms may be combined with other forms of contraception ( such as spermicide ) for greater protection .

 Condoms are widely recommended for the prevention of sexually transmitted infections ( STIs ) . They have been shown to be effective in reducing infection rates in both men and women , but not eliminating it . While not perfect , the condom is effective at reducing the transmission of organisms that cause AIDS , genital herpes , cervical cancer , genital warts , syphilis , <unk> , <unk> , and other diseases . Condoms are often recommended as an <unk> to more effective birth control methods ( such as <unk> ) in situations where STD protection is also desired . 
 According to a 2000 report by the National Institutes of Health ( <unk> ) , consistent use of latex condoms reduces the risk of HIV / AIDS transmission by approximately 85 % relative to risk when unprotected , putting the <unk> rate ( infection rate ) at 0 @.@ 9 per 100 person @-@ years with condom , down from 6 @.@ 7 per 100 person @-@ years . Analysis published in 2007 from the University of Texas Medical Branch and the World Health Organization found similar risk reductions of 80 – 95 % . 
 The 2000 <unk> review concluded that condom use significantly reduces the risk of <unk> for men . A 2006 study reports that proper condom use decreases the risk of transmission of human <unk> ( <unk> ) to women by approximately 70 % . Another study in the same year found consistent condom use was effective at reducing transmission of herpes <unk> virus @-@ 2 also known as genital herpes , in both men and women . 
 Although a condom is effective in limiting exposure , some disease transmission may occur even with a condom . <unk> areas of the <unk> , especially when symptoms are present , may not be covered by a condom , and as a result , some diseases like <unk> and herpes may be transmitted by direct contact . The primary effectiveness issue with using condoms to prevent STDs , however , is inconsistent use . 
 Condoms may also be useful in treating potentially <unk> cervical changes . Exposure to human <unk> , even in individuals already infected with the virus , appears to increase the risk of <unk> changes . The use of condoms helps promote regression of these changes . In addition , researchers in the UK suggest that a hormone in semen can <unk> existing cervical cancer , condom use during sex can prevent exposure to the hormone . 
 
 = = = Causes of failure = = = 
 
 Condoms may slip off the penis after ejaculation , 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 % . Even if no breakage or slippage is observed , 1 – 3 % of women will test positive for semen residue after intercourse with a condom . 
 " Double <unk> " , using two condoms at once , is often believed to cause a higher rate of failure due to the friction of rubber on rubber . This claim is not supported by research . The limited studies that have been done on the subject support that double <unk> is likely not harmful and possibly beneficial . 
 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 . 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 . 
 Standard condoms will fit almost any penis , with varying degrees of comfort or risk of slippage . Many condom manufacturers offer " <unk> " or " magnum " sizes . Some manufacturers also offer custom sized @-@ to @-@ fit condoms , with claims that they are more reliable and offer improved sensation / comfort . Some studies have associated larger <unk> and smaller condoms with increased breakage and decreased slippage rates ( and vice versa ) , but other studies have been inconclusive . 
 It is recommended for condoms manufacturers to avoid very thick or very thin condoms , because they are both considered less effective . Some authors encourage users to choose thinner condoms " for greater <unk> , sensation , and comfort " , but others warn that " the thinner the condom , the smaller the force required to break it " . 
 <unk> 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 . An article in Population Reports suggests that education on condom use reduces behaviors that increase the risk of breakage and slippage . 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 . 
 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 ) . 
 Another possible cause of condom failure is sabotage . One motive is to have a child against a partner 's wishes or consent . Some commercial sex workers from Nigeria reported clients <unk> condoms in retaliation for being coerced into condom use . Using a fine needle to make several <unk> at the tip of the condom is believed to significantly impact their effectiveness . Cases of such condom sabotage have occurred .

 The use of latex condoms by people with an allergy to latex can cause allergic symptoms , such as skin irritation .

 Male condoms are usually packaged inside a foil or plastic <unk> , in a rolled @-@ up form , and are designed to be applied to the tip of the penis and then <unk> 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 . Condoms are used to reduce the likelihood of pregnancy during intercourse and to reduce the likelihood of contracting sexually @-@ transmitted infections ( STIs ) . Condoms are also used during <unk> to reduce the likelihood of contracting STIs . 
 Some couples find that putting on a condom interrupts sex , although others incorporate condom application as part of their <unk> . Some men and women find the physical barrier of a condom <unk> sensation . <unk> of <unk> sensation can include prolonged erection and delayed ejaculation ; disadvantages might include a loss of some sexual excitement . <unk> of condom use also cite their advantages of being inexpensive , easy to use , and having few side effects .

 In 2012 proponents gathered 372 @,@ 000 <unk> signatures through a citizens ' initiative in Los Angeles County to put Measure B on the 2012 ballot .

 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 <unk> Association ( <unk> ) 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 . " 
 In the United States , teaching about condoms in public schools is opposed by some religious organizations . Planned <unk> , 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 76 % of American parents want their children to receive comprehensive sexuality education including condom use .

 Common procedures in infertility treatment such as semen analysis and <unk> insemination ( <unk> ) 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 <unk> 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 <unk> , 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 <unk> or <unk> insemination . <unk> of religions that prohibit contraception , such as Catholicism , may use collection condoms with holes <unk> in them . 
 For fertility treatments , a collection condom may be used to collect semen during sexual intercourse where the semen is provided by the woman 's partner . Private sperm donors may also use a collection condom to obtain samples through masturbation or by sexual intercourse with a partner and will transfer the <unk> from the collection condom to a specially designed container . The sperm is transported in such containers , in the case of a donor , to a recipient woman to be used for insemination , and in the case of a woman 's partner , to a fertility clinic for processing and use . However , transportation may reduce the <unk> of the sperm . Collection condoms may also be used where semen is produced at a sperm bank or fertility clinic . 
 Condom therapy is sometimes prescribed to infertile couples when the female has high levels of <unk> antibodies . The theory is that preventing exposure to her partner 's semen will lower her level of <unk> 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 .

 Condoms <unk> as multipurpose containers and barriers because they are <unk> , elastic , durable , and ( for military and espionage uses ) will not <unk> suspicion if found . 
 <unk> military <unk> began during World War II , and includes covering the <unk> of rifle barrels to prevent <unk> , the waterproofing of firing assemblies in underwater <unk> , and storage of corrosive materials and <unk> by paramilitary agencies . 
 Condoms have also been used to smuggle alcohol , 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 <unk> . These methods are very dangerous and potentially lethal ; if the condom breaks , the drugs inside become absorbed into the bloodstream and can cause an <unk> . 
 <unk> , condoms can be used to cover <unk> <unk> probes , or in field chest needle <unk> they can be used to make a one @-@ way valve . 
 Condoms have also been used to protect scientific samples from the environment , and to <unk> microphones for underwater recording .

 Most condoms have a reservoir tip or <unk> end , making it easier to accommodate the man 's <unk> . Condoms come in different sizes , from oversized to <unk> and they also come in a variety of surfaces intended to stimulate the user 's partner . Condoms are usually supplied with a <unk> 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 also exist .

 Latex has outstanding elastic properties : Its tensile strength exceeds 30 MPa , and latex condoms may be stretched in excess of 800 % before breaking . In 1990 the <unk> set standards for condom production ( <unk> <unk> , Natural latex rubber condoms ) , and the EU followed suit with its <unk> standard ( Directive 93 / 42 / EEC concerning medical devices ) . Every latex condom is tested for holes with an electric 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 . 
 While the advantages of latex have made it the most popular condom material , it does have some drawbacks . Latex condoms are damaged when used with oil @-@ based substances as lubricants , such as petroleum <unk> , cooking oil , baby oil , mineral oil , skin <unk> , <unk> <unk> , cold <unk> , butter or <unk> . Contact with oil makes latex condoms more likely to break or slip off due to loss of elasticity caused by the oils . Additionally , latex allergy <unk> 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 <unk> Administration granted approval for the production of condoms composed of <unk> , latex that has been treated to remove 90 % of the proteins responsible for allergic reactions . An <unk> @-@ free condom made of synthetic latex ( polyisoprene ) is also available .

 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 . 
 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 . 
 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 <unk> than latex , and does not have an odor . 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 . 
 However , polyurethane condoms are less elastic than latex ones , and may be more likely to slip or break than latex , lose their shape or bunch up more than latex , and are more expensive . 
 <unk> is a synthetic version of natural rubber latex . While significantly more expensive , it has the advantages of latex ( such as being softer and more elastic than polyurethane condoms ) without the protein which is responsible for latex <unk> . Like polyurethane condoms , polyisoprene condoms are said to do a better job of transmitting body heat . Unlike polyurethane condoms , they cannot be used with an oil @-@ based <unk> .

 Condoms made from sheep intestines , labeled " lambskin " , are also available . Although they are generally effective as a contraceptive by blocking sperm , it is presumed that they are likely less effective than latex in preventing the transmission of agents that cause STDs , because of pores in the material . This is based on the idea that intestines , by their nature , are porous , <unk> membranes , and while sperm are too large to pass through the pores , viruses — such as HIV , herpes , and genital warts — are small enough to pass through . However , there are to date no clinical data confirming or denying this theory . Some believe that lambskin condoms provide a more " natural " sensation , and they lack the <unk> that are inherent to latex , but because of their lesser protection against infection , other <unk> materials such as polyurethane are recommended for latex @-@ allergic users and / or partners . <unk> condoms are also significantly more expensive than other types and as slaughter by @-@ products they are also not vegetarian .

 Some latex condoms are lubricated at the manufacturer with a small amount of a nonoxynol @-@ 9 , a <unk> 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 . In contrast , application of separately packaged spermicide is believed to increase the contraceptive <unk> of condoms . 
 <unk> @-@ 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 . The World Health Organization says that <unk> lubricated condoms should no longer be promoted . However , it recommends using a nonoxynol @-@ 9 lubricated condom over no condom at all . As of 2005 , nine condom manufacturers have stopped manufacturing condoms with nonoxynol @-@ 9 and Planned <unk> has discontinued the distribution of condoms so lubricated .

 In March 2010 , the Swiss government announced that it was planning to promote smaller condoms intended for boys and youths of 12 – 14 years old following concern about the pregnancy rate among adolescent girls , and also about the potential spread of AIDS among this age group . This was due to the fact that standard condoms were too wide and consequently failed to afford protection to adolescent boys during vaginal and anal intercourse . Family planning groups and the Swiss AIDS Federation had campaigned to have a narrower condom produced for youths after a number of studies , including a government study researched at the Centre for Development and Personality Psychology at Basel University , found that standard condoms were unsuitable for boys in this age range , and that the condoms either failed during use or that the boys rejected them altogether because they were too wide , and consequently they used no protection at all . 
 As a result of these studies , a condom aimed at <unk> to 14 @-@ year @-@ old boys is now produced and is available in Switzerland and in certain other countries . Manufactured by <unk> , the " <unk> " is a lubricated , <unk> @-@ ended latex condom which is narrower than a standard condom and has a tight band at the opening to ensure that it remains on the youth 's penis during intercourse . A standard condom has a diameter of 2 inches ( 5 @.@ 2 cm ) whereas the <unk> has a diameter of 1 @.@ 7 inches ( 4 @.@ 5 cm ) . Both are the same length – 7 @.@ 4 inches ( 19 cm ) . In 2014 , in response to demand for condoms from a younger age @-@ group , German condom manufacturer Amor started producing another condom aimed at young people .

 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 .

 Whether condoms were used in ancient civilizations is debated by archaeologists and historians . In ancient Egypt , Greece , and Rome , pregnancy prevention was generally seen as a woman 's responsibility , and the only well documented contraception methods were female @-@ controlled devices . In Asia before the 15th century , some use of glans condoms ( devices covering only the head of the penis ) is recorded . Condoms seem to have been used for contraception , and to have been known only by members of the upper classes . In China , glans condoms may have been made of <unk> silk paper , or of lamb intestines . In Japan , they were made of tortoise shell or animal horn . 
 In 16th century Italy , <unk> Falloppio wrote a treatise on syphilis . The earliest documented strain of syphilis , first appearing in Europe in a <unk> outbreak , caused severe symptoms and often death within a few months of contracting the disease . Falloppio 's treatise is the earliest uncontested description of condom use : it describes linen <unk> soaked in a chemical solution and allowed to dry before use . The <unk> he described were sized to cover the glans of the penis , and were held on with a ribbon . Falloppio claimed that an experimental trial of the linen sheath demonstrated protection against syphilis . 
 After this , the use of penis <unk> to protect from disease is described in a wide variety of literature throughout Europe . The first indication that these devices were used for birth control , rather than disease prevention , is the 1605 theological publication De <unk> et <unk> ( On justice and law ) by Catholic theologian <unk> <unk> , who condemned them as immoral . In 1666 , the English Birth <unk> Commission attributed a recent downward fertility rate to use of " <unk> " , the first documented use of that word ( or any similar spelling ) . 
 In addition to linen , condoms during the Renaissance were made out of intestines and <unk> . In the late 16th century , Dutch traders introduced condoms made from " fine leather " to Japan . Unlike the horn condoms used previously , these leather condoms covered the entire penis . 
 <unk> in the 18th century was one of the first reported using " assurance caps " to prevent <unk> his <unk> . 
 From at least the 18th century , condom use was opposed in some legal , religious , and medical circles for essentially the same reasons that are given today : condoms reduce the likelihood of pregnancy , which some thought immoral or undesirable for the nation ; they do not provide full protection against sexually transmitted infections , while belief in their protective powers was thought to encourage sexual promiscuity ; and , they are not used consistently due to <unk> , expense , or loss of sensation . 
 Despite some opposition , the condom market grew rapidly . In the 18th century , condoms were available in a variety of qualities and sizes , made from either linen treated with chemicals , or " skin " ( <unk> or intestine softened by treatment with sulfur and <unk> ) . They were sold at <unk> , <unk> , chemist shops , open @-@ air markets , and at the theater throughout Europe and Russia . They later spread to America , although in every place there were generally used only by the middle and upper classes , due to both expense and lack of sex education .

 The early 19th century saw contraceptives promoted to the poorer classes for the first time . Writers on contraception tended to prefer other methods of birth control to the condom . By the late 19th century many <unk> expressed distrust of the condom as a contraceptive , as its use was controlled and decided upon by men alone . They advocated instead for methods which were controlled by women , such as <unk> and <unk> <unk> . Other writers cited both the expense of condoms and their <unk> ( they were often riddled with holes , and often fell off or broke ) , but they discussed condoms as a good option for some , and as the only contraceptive that also protected from disease . 
 Many countries passed laws <unk> the manufacture and promotion of contraceptives . In spite of these restrictions , condoms were promoted by traveling <unk> and in newspaper advertisements , using <unk> in places where such <unk> were illegal . <unk> on how to make condoms at home were distributed in the United States and Europe . Despite social and legal opposition , at the end of the 19th century the condom was the Western world 's most popular birth control method . 
 Beginning in the second half of the 19th century , American rates of sexually transmitted diseases <unk> . Causes cited by historians include effects of the American Civil War , and the ignorance of prevention methods promoted by the <unk> laws . To fight the growing epidemic , sex education classes were introduced to public schools for the first time , teaching about <unk> diseases and how they were transmitted . They generally taught that abstinence was the only way to avoid sexually transmitted diseases . Condoms were not promoted for disease prevention because the medical community and moral <unk> considered STDs to be punishment for sexual <unk> . The stigma against victims of these diseases was so great that many hospitals refused to treat people who had syphilis . 
 The German military was the first to promote condom use among its soldiers , beginning in the later 19th century . Early 20th century experiments by the American military concluded that providing condoms to soldiers significantly lowered rates of sexually transmitted diseases . During World War I , the United States and ( at the beginning of the war only ) Britain were the only countries with soldiers in Europe who did not provide condoms and promote their use . 
 In the decades after World War I , there remained social and legal obstacles to condom use throughout the U.S. and Europe . <unk> of <unk> Sigmund Freud opposed all methods of birth control on the grounds that their failure rates were too high . Freud was especially opposed to the condom because he thought it cut down on sexual pleasure . Some <unk> continued to oppose male @-@ controlled contraceptives such as condoms . In 1920 the Church of England 's Lambeth Conference condemned all " unnatural means of conception avoidance " . London 's Bishop Arthur <unk> @-@ Ingram complained of the huge number of condoms discarded in alleyways and parks , especially after weekends and holidays . 
 However , European militaries continued to provide condoms to their members for disease protection , even in countries where they were illegal for the general population . Through the 1920s , catchy names and slick packaging became an increasingly important marketing technique for many consumer items , including condoms and cigarettes . Quality testing became more common , involving filling each condom with air followed by one of several methods intended to detect loss of pressure . Worldwide , condom sales doubled in the 1920s .

 In 1839 , Charles <unk> discovered a way of processing natural rubber , which is too stiff when cold and too soft when warm , in such a way as to make it elastic . This proved to have advantages for the manufacture of condoms ; unlike the sheep 's gut condoms , they could stretch and did not tear quickly when used . The rubber <unk> process was patented by <unk> in 1844 . The first rubber condom was produced in 1855 . The earliest rubber condoms had a seam and were as thick as a bicycle inner tube . Besides this type , small rubber condoms covering only the glans were often used in England and the United States . There was more risk of losing them and if the rubber ring was too tight , it would <unk> the penis . This type of condom was the original " <unk> " ( French for condom ) , perhaps because of its resemblance to a woman 's bonnet worn at that time , also called a <unk> . 
 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 . In 1912 , Polish inventor Julius <unk> developed a new , improved manufacturing technique for condoms : dipping glass molds into a raw rubber solution . Called cement dipping , this method required adding gasoline or benzene to the rubber to make it liquid . 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 <unk> by rubbing and <unk> . 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 ) . 
 Until the twenties , all condoms were individually hand @-@ dipped by semi @-@ skilled workers . Throughout the decade of the 1920s , advances in the <unk> of the condom assembly line were made . The first fully automated line was patented in 1930 . Major condom manufacturers bought or leased <unk> systems , and small manufacturers were driven out of business . The skin condom , now significantly more expensive than the latex variety , became restricted to a niche high @-@ end market .

 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 . The Roman Catholic Church responded by issuing the encyclical <unk> <unk> <unk> its opposition to all contraceptives , a stance it has never reversed . 
 In the 1930s , legal restrictions on condoms began to be relaxed . But during this period <unk> Italy and Nazi Germany increased restrictions on condoms ( limited sales as disease <unk> were still allowed ) . During the Depression , condom lines by <unk> gained in popularity . <unk> 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 . <unk> , while less comfortable , these older @-@ style rubber condoms could be reused and so were more economical , a valued feature in hard times . More attention was brought to quality issues in the 1930s , and the U.S. Food and <unk> Administration began to regulate the quality of condoms sold in the United States . 
 Throughout World War II , condoms were not only distributed to male U.S. military members , but also heavily promoted with films , posters , and lectures . 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 . 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 <unk> , 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 <unk> " : by 1970 hundreds of millions of condoms were being used each year in India alone . ( This number has grown in recent decades : in 2004 , the government of India purchased 1 @.@ 9 billion condoms for distribution at family planning clinics . ) 
 In the 1960s and 1970s quality regulations <unk> , and more legal barriers to condom use were removed . In Ireland , legal condom sales were allowed for the first time in 1978 . Advertising , however was one area that continued to have legal restrictions . In the late 1950s , the American National Association of <unk> banned condom advertisements from national television : this policy remained in place until 1979 . 
 After learning in the early 1980s that AIDS can be a sexually transmitted infection , 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 . These campaigns increased condom use significantly . 
 Due to increased demand and greater social acceptance , condoms began to be sold in a wider variety of retail outlets , including in <unk> and in discount department stores such as Wal @-@ Mart . Condom sales increased every year until 1994 , when media attention to the AIDS pandemic began to decline . The phenomenon of decreasing use of condoms as disease <unk> has been called prevention fatigue or condom fatigue . Observers have cited condom fatigue in both Europe and North America . As one response , manufacturers have changed the tone of their advertisements from scary to humorous . 
 New developments continued to occur in the condom market , with the first polyurethane condom — branded <unk> and produced by the manufacturer of <unk> — introduced in the 1990s , and the first custom sized @-@ to @-@ fit condom , called <unk> , introduced in the early 2000s . 
 Worldwide condom use is expected to continue to grow : one study predicted that developing nations would need 18 @.@ 6 billion condoms by 2015 . As of September 2013 , condoms are available inside prisons in Canada , most of the European Union , Australia , Brazil , Indonesia , South Africa , and the US states of Vermont ( on September 17 , 2013 , the Californian Senate approved a bill for condom distribution inside the state 's prisons , but the bill was not yet law at the time of approval ) .

 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 . 
 A variety of unproven Latin etymologies have been proposed , including <unk> ( receptacle ) , <unk> ( house ) , and <unk> ( <unk> or case ) . It has also been speculated to be from the Italian word <unk> , derived from <unk> , meaning <unk> . William E. <unk> 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 . " Modern dictionaries may also list the etymology as " unknown " . 
 Other terms are also commonly used to describe condoms . In North America condoms are also commonly known as <unk> , or rubbers . In Britain they may be called French letters . Additionally , condoms may be referred to using the manufacturer 's name .

 Some moral and scientific criticism of condoms exists despite the many benefits of condoms agreed on by scientific consensus and sexual health experts . 
 Condom usage is typically recommended for new couples who have yet to develop full trust in their partner with regard to STDs . Established couples on the other hand have few concerns about STDs , and can use other methods of birth control such as the pill , which does not act as a barrier to intimate sexual contact . Note that the polar debate with regard to condom usage is <unk> by the target group the argument is directed . Notably the age category and stable partner question are factors , as well as the distinction between heterosexual and homosexuals , who have different kinds of sex and have different risk consequences and factors . 
 Among the prime objections to condom usage is the blocking of erotic sensation , and / or the intimacy that barrier @-@ free sex provides . As the condom is held tightly to the skin of the penis , it <unk> the delivery of stimulation through rubbing and friction . Condom proponents claim this has the benefit of making sex last longer , by diminishing sensation and delaying male ejaculation . Those who promote condom @-@ free heterosexual sex ( slang : " <unk> " ) claim that the condom puts a <unk> barrier between partners , diminishing what is normally a highly sensual , intimate , and spiritual connection between partners .

 Roman Catholic Church opposes all kinds of sexual acts outside of marriage , as well as any sexual act in which the chance of successful conception has been reduced by direct and intentional acts ( for example , surgery to prevent conception ) or foreign objects ( for example , condoms ) . 
 The use of condoms to prevent STD transmission 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 <unk> <unk> , believe the Catholic Church should actively support condoms used to prevent disease , especially serious diseases such as AIDS . However , the majority view — including all statements from the Vatican — is that condom @-@ promotion programs encourage promiscuity , thereby actually increasing STD transmission . This view was most recently reiterated in 2009 by Pope Benedict XVI . 
 The Roman Catholic Church is the largest organized body of any world religion . The church has hundreds of programs dedicated to fighting the AIDS epidemic in Africa , but its opposition to condom use in these programs has been highly controversial . 
 In a November 2011 interview , the Pope discussed for the first time the use of condoms to prevent STD transmission . He said that the use of a condom can be justified in a few individual cases if the purpose is to reduce the risk of an HIV infection . He gave as an example male prostitutes . There was some confusion at first whether the statement applied only to homosexual prostitutes and thus not to heterosexual intercourse at all . However , Federico Lombardi , spokesman for the Vatican , clarified that it applied to heterosexual and <unk> prostitutes , whether male or female , as well . He did , however , also clarify that the Vatican 's principles on sexuality and contraception had not been changed .

 More generally , some scientific researchers have expressed objective concern over certain ingredients sometimes added to condoms , notably <unk> and <unk> . Dry <unk> <unk> are applied to latex condoms before packaging to prevent the condom from sticking to itself when rolled up . Previously , <unk> was used by most manufacturers , but <unk> is currently the most popular <unk> powder . <unk> is known to be toxic if it enters the abdominal cavity ( i.e. , via the <unk> ) . <unk> is generally believed to be safe ; however , some researchers have raised concerns over its use as well . 
 <unk> , which are potentially carcinogenic in humans , are believed to be present in a substance used to improve elasticity in latex condoms . A 2001 review stated that humans regularly receive 1 @,@ 000 to 10 @,@ 000 times greater <unk> exposure from food and tobacco than from condom use and concluded that the risk of cancer from condom use is very low . However , a 2004 study in Germany detected <unk> in 29 out of 32 condom brands tested , and concluded that exposure from condoms might exceed the exposure from food by <unk> to 3 @-@ fold . 
 In addition , the large @-@ scale use of <unk> condoms has resulted in concerns over their environmental impact via <unk> and in <unk> , where they can eventually wind up in wildlife environments if not <unk> or otherwise permanently disposed of first . Polyurethane condoms in particular , given they are a form of plastic , are not biodegradable , and latex condoms take a very long time to break down . Experts , such as <unk> , recommend condoms be disposed of in a garbage receptacle , as <unk> them down the toilet ( which some people do ) may cause <unk> <unk> and other problems . Furthermore , the plastic and foil <unk> condoms are packaged in are also not biodegradable . However , the benefits condoms offer are widely considered to offset their small landfill mass . Frequent condom or <unk> disposal in public areas such as a parks have been seen as a persistent litter problem . 
 While biodegradable , 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 <unk> 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 .

 In much of the Western world , the introduction of the pill in the 1960s was associated with a decline in condom use . In Japan , oral contraceptives were not approved for use until September 1999 , and even then access was more restricted than in other <unk> nations . Perhaps because of this restricted access to <unk> contraception , Japan has the highest rate of condom usage in the world : in 2008 , 80 % of contraceptive users relied on condoms . 
 Cultural attitudes toward gender roles , contraception , and sexual activity vary greatly around the world , and range from extremely conservative to extremely liberal . But in places where condoms are misunderstood , <unk> , <unk> , or looked upon with overall cultural disapproval , the prevalence of condom use is directly affected . In less @-@ developed countries and among less @-@ educated populations , <unk> about how disease transmission and conception work negatively affect the use of condoms ; additionally , in cultures with more traditional gender roles , women may feel uncomfortable demanding that their partners use condoms . 
 As an example , Latino immigrants in the United States often face cultural 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 because of the general machismo subtly encouraged in Latino culture , their male partners would be angry or possibly violent at the woman 's suggestion that they use condoms . A similar phenomenon has been noted in a survey of low @-@ income American black women ; the women in this study also reported a fear of violence at the suggestion to their male partners that condoms be used . 
 A telephone survey conducted by Rand Corporation and Oregon State University , and published in the Journal of <unk> <unk> <unk> <unk> showed that belief in AIDS conspiracy theories among United States black men is linked to rates of condom use . As conspiracy beliefs about AIDS grow in a given sector of these black men , consistent condom use drops in that same sector . Female use of condoms was not similarly affected . 
 In the African continent , condom promotion in some areas has been impeded by anti @-@ condom campaigns by some Muslim and Catholic clerics . Among the Maasai in Tanzania , condom use is hampered by an aversion to " wasting " sperm , which is given <unk> importance beyond reproduction . <unk> is believed to be an " elixir " to women and to have beneficial health effects . Maasai women believe that , after <unk> 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 Maasai to cause impotence . Some women in Africa believe that condoms are " for prostitutes " and that respectable women should not use them . A few clerics even promote the idea that condoms are deliberately laced with HIV . In the United States , possession of many condoms has been used by police to accuse women of engaging in prostitution . The Presidential Advisory Council on HIV / AIDS has condemned this practice and there are efforts to end it . 
 In March 2013 , technology <unk> Bill Gates offered a US $ 100 @,@ 000 grant through his foundation for a condom design that " significantly preserves or enhances pleasure " to encourage more males to adopt the use of condoms for safer sex . The grant information states : “ The primary drawback from the male perspective is that condoms decrease pleasure as compared to no condom , creating a trade @-@ off that many men find unacceptable , particularly given that the decisions about use must be made just prior to intercourse . Is it possible to develop a product without this stigma , or better , one that is felt to enhance pleasure ? ” The project has been named the " Next Generation Condom " and anyone who can provide a " <unk> hypothesis " is eligible to apply . 
 Middle @-@ Eastern couples who have not had children , because of the strong desire and social pressure to establish fertility as soon as possible within marriage , rarely use condoms .

 One analyst described the size of the condom market as something that " <unk> the mind " . Numerous small manufacturers , <unk> groups , and government @-@ run manufacturing plants exist around the world . 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 .

 A <unk> @-@ 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 <unk> @-@ on condom was not going to market because the drying time could not be reduced below two to three minutes . 
 The Invisible Condom , developed at <unk> <unk> in <unk> , Canada , is a gel that <unk> upon increased temperature after insertion into the <unk> or <unk> . In the lab , it has been shown to effectively block HIV and herpes <unk> virus . The barrier breaks down and <unk> after several hours . As of 2005 , the invisible condom is in the clinical trial phase , and has not yet been approved for use . 
 Also developed in 2005 is a condom treated with an <unk> 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 <unk> brand . As of 2007 , it was still in clinical trials . In 2009 , <unk> Healthcare , the makers of <unk> condoms , introduced the <unk> condom lubricated with " <unk> <unk> " which contains the amino acid l @-@ <unk> and is intended to improve the strength of the <unk> response .
