Condom

Un article de Vev.

Modèle:Dablink Modèle:BirthControl infobox A condom is a device that is most commonly used during sexual intercourse. It is put on a man's erect penis and physically blocks ejaculated semen from entering the body of a sexual partner. Condoms are used to prevent pregnancy and transmission of sexually transmitted diseases (STDs—such as gonorrhea, syphilis, and HIV). Because condoms are waterproof, elastic, and durable, they are also used in a variety of secondary applications. These range from creating waterproof microphones to protecting rifle barrels from clogging.

Condoms are most commonly made from latex, but some are made from other materials. A female condom is also available. As a method of contraception, male condoms have the advantage of being inexpensive, easy to use, having few side-effects, and of offering protection against sexually transmitted diseases.<ref name="fwhc"> Male Condom

Condoms have been used for over 500 years.<ref name=pp /><ref name=pai /> In the early twentieth century, with the invention of disposible latex condoms, they became one of the most popular methods of contraception. While widely accepted in modern times, condoms have generated some controversy. Improper disposal of condoms contributes to litter problems, and the Roman Catholic Church generally opposes condom use.

History

Antiquity

An Egyptian drawing of a condom being worn has been found to be 3,000 years old. It is unknown, however, if the Egyptian pictured wearing the device intended to use it for contraception, or for ritual purposes.<ref name=pp /> The Greek legend of Minos as related by Antoninus Liberalis in 150 AD described the use of a goat's bladder as a protective measure during intercourse, although purpose or intent of the practice is not fully known.<ref name="youssef">Modèle:Cite journal</ref>

In 16th century Italy, Gabriele Falloppio authored the first-known published description of condom use for disease prevention. He recommended soaking cloth sheaths in a chemical solution and allowing them to dry prior to use.<ref name=pai> Special Topic: History of Condom Use

The oldest condoms found (rather than just pictures or descriptions) are from 1640, discovered in Dudley Castle in England. They were made of animal intestine, and it is believed they were used for STD prevention.<ref name=pp /> In 19th century Japan, both leather condoms and condoms made of tortoise shells or horns were available.<ref name=pai /> Similar devices made from oiled silk paper have also been described in China.<ref name="youssef"/>

The often-reported invention of the condom by "Dr. Condom" or the "Earl of Condom" is believed to be fallacious (see etymology section below). However in the 18th Century, there are numerous literary references to condom use and sales, including in the memoirs of Giacomo Casanova.<ref name="youssef"/>

19th century to present

The rubber vulcanization process was patented by Charles Goodyear in 1844, and the first rubber condom was produced in 1855.<ref name=billy> Rubbers haven't always been made of rubber

Distribution of condoms in the United States was limited by passage of the Comstock Act in 1873. This law prohibited transport through the postal service of any instructional material or devices intended to prevent pregnancy. Condoms were available by prescription, although legally they were only supposed to be prescribed to prevent disease rather than pregnancy.<ref name=pp /> The Comstock Act remained in force until it was largely overturned by the U.S. Supreme Court in 1936.

In 1912, a German named Julius Fromm developed a new manufacturing technique for condoms: dipping glass molds into the raw rubber solution. This enabled the production of thinner condoms with no seams. Fromm's Act was the first branded line of condoms, and Fromms is still a popular line of condoms in Germany today.<ref name=billy /> By the 1930s, the manufacturing process had improved to produce single-use condoms almost as thin and inexpensive as those currently available.<ref name=pai />

Condoms were not made available to U.S. soldiers in World War I, and a significant number of returning soldiers carried sexually transmitted infections. During World War II, however, condoms were heavily promoted to soldiers, with one film exhorting "Don't forget — put it on before you put it in."<ref name=pp /> In part because condoms were readily available, soldiers found a number of non-sexual uses for the devices, many of which continue to be utilized to this day.

Varieties

Most condoms have a reservoir tip, making it easier to leave space for the man's ejaculate. Condoms also come in different sizes, from oversized to snug. As mentioned above, most condoms are made of latex, but polyurethane and lambskin condoms are also widely available.

Latex

Latex has outstanding elastic properties: Its tensile strength exceeds 30 MPa, and latex condoms may be stretched in excess of 800% before breaking.<ref>Modèle:Cite journal</ref> 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.<ref name="badnews">Modèle:Cite journal</ref>

Latex condoms used with oil-based lubricants (e.g. vaseline) are likely to slip off due to loss of elasticity caused by the oils.<ref name="fhi3">Modèle:Cite journal</ref>

Some latex condoms are lubricated at the manufacturer with a small amount of a nonoxynol-9, a spermicidal chemical. According to Consumer Reports, spermicidally lubricated condoms have no additional benefit in preventing pregnancy, have a shorter shelf life, and may cause urinary-tract infections in women.<ref> Condoms: Extra protection

Lambskin

Condoms made from one of the oldest condom materials, labeled "lambskin" (made from lamb intestines) are still available. They have a greater ability to transmit body warmth and tactile sensation, when compared to synthetic condoms, 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.<ref>Modèle:Cite book</ref>

Effectiveness

In preventing pregnancy

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 improperly, inconsistently, or both. Rates are generally presented for the first year of use.<ref name="hatcher" /> Most commonly the Pearl Index is used to calculate effectiveness rates, but some studies use decrement tables.<ref>Modèle:Cite book</ref>

The typical use pregnancy rate among condom users varies depending on the population being studied, ranging from 10–18% per year.<ref>Kippley (1996), p.146, which cites:

Modèle:Cite journal</ref> The perfect use pregnancy rate of condoms is 2% per year.<ref name="hatcher" /> Condoms may be combined with other forms of contraception (such as spermicide) for greater protection.<ref name="simultaneous">Modèle:Cite journal</ref>

Several factors account for typical use effectiveness being lower than perfect use effectiveness:

• mistakes on the part of those providing instructions on how to use the method
• mistakes on the part of the user
• conscious user non-compliance with instructions.

For instance, someone using condoms might be given incorrect information on what lubricants are safe to use with condoms, or by mistake put the condom on improperly, or simply not bother to use a condom.

In preventing STDs

Modèle:Seealso 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 HIV, genital herpes, genital warts, syphilis, chlamydia, gonorrhea, and other diseases.<ref> The Condom

. Planned Parenthood 
 
 (2004-01-04)
   

. Retrieved on 2007-06-07. </ref>

According to a 2000 report by the National Institutes of Health, correct and consistent use of latex condoms reduces the risk of HIV/AIDS transmission by approximately 85% relative to risk when unprotected. The same review also found condom use significantly reduces the risk of gonorrhea for men.<ref>Modèle:Cite conference</ref>

A 2006 study reports that proper condom use decreases the risk of transmission for human papilloma virus by approximately 70%.<ref>Modèle:Cite journal</ref> 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.<ref>Modèle:Cite journal</ref>

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.<ref> Villhauer , Tanya

Causes of failure

Modèle:Wikibookspar Condom users may experience slipping off the penis after ejaculation,<ref>Modèle:Cite journal</ref> breakage due to faulty methods of application or physical damage (such as tears caused when opening the package), or breakage or slippage due to latex degradation (typically from being past the expiration date or being stored improperly). Even if no breakage or slippage is observed, 1–2% of women will test positive for semen residue after intercourse with a condom.<ref>Modèle:Cite journal</ref><ref name="pinhole">Modèle:Cite journal</ref>

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.<ref>Modèle:Cite journal</ref> 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.<ref>Modèle:Cite journal</ref>

Standard condoms will fit almost any penis, although many condom manufacturers offer "snug" or "magnum" sizes. 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.<ref name="fhi3" />

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 at increased risk of a second such failure.<ref>Modèle:Cite journal
Modèle:Cite journal</ref> An article in Population Reports suggests that education on condom use reduces behaviors that increase the risk of breakage and slippage.<ref>Modèle:Cite journal</ref> 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.<ref name="fhi3" />

Among couples that intend condoms to be their form of birth control, pregnancy may occur when the couple does not use a condom. The couple 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).<ref>Modèle:Cite journal</ref>

Another possible cause of condom failure is sabotage. One motive is to have a child against a partner's wishes or consent.<ref> Childfree And The Media

Female condoms

Main article: Female condom

"Female condoms" or "femidoms" are also available. They are larger and wider than male condoms but equivalent in length. They have a flexible ring-shaped opening, and are designed to be inserted into the vagina. They also contain an inner ring which aids insertion and helps keep the condom from sliding out of the vagina during coitus. One line of female condoms is made from polyurethane or nitrile polymer. A competing manufacturer makes a line of female condoms out of latex. The latex female condom has been available for several years in Africa, Asia, and South America, although one more clinical trial is required before it can be submitted for FDA approval in the United States.

Use

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 rolled over the erect penis. After use, it is recommended the condom be wrapped in tissue or tied in a knot, then disposed of in a trash receptacle.<ref name="AliceDisposal" />

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.<ref name="planned parenthood" />

Prevalence

The prevalence of condom use varies greatly between countries. Japan has the highest rate of condom usage in the world, with condoms accounting for almost 80% of contraceptive use. In the average developed country, 22% of contraceptive users rely on condoms as their primary method of birth control. In the average less-developed country, only 5-6% of contraceptive users choose condoms.<ref>Modèle:Cite paper Data from surveys in the late 1990s.</ref> In a few countries, such as Somalia, condoms are illegal.<ref name="cbs">"

Role in sex education

Condoms are often used in sexual 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."<ref>Modèle:Cite press release</ref>

In the United States, teaching about condoms in public schools is opposed by some religious organizations.<ref>Modèle:Cite paper</ref> Planned Parenthood, which advocates family planning and sexual 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.<ref> Sex & Censorship Committee, National Coalition Against Censorship

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 to 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 IUI.<ref>Modèle:Cite paper</ref> Adherents of religions that prohibit contraception, such as Catholicism, may use collection condoms with holes pricked in them.<ref name="kippley" />

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.<ref>Modèle:Cite journal

• Condoms have also been used in many cases to smuggle cocaine 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; if the condom breaks, the drugs inside can cause an overdose.<ref>"A 41-year-old man has been remanded in custody after being stopped on Saturday by customs officials at the Norwegian border at Svinesund. He had a kilo of cocaine in his stomach." Smuggler hospitalised as cocaine condom bursts</ref>
• 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 litres 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. Alexander Solzhenitsyn records that the three litres of raw fluid would be diluted to make seven litres 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.<ref>Modèle:Cite book</ref>
