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. With proper knowledge and application technique—and use at every act of intercourse—users of male condoms experience a 2% per-year pregnancy rate.

Condoms have been used for at least 400 years. Since the nineteenth 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. Improper disposal of condoms contributes to litter problems, and the Roman Catholic Church

History


Before the 19th century

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 fifteenth 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 oiled silk paper, or of lamb intestines. In Japan, they were made of tortoise shell or animal horn.

. The earliest documented strain of syphilis, first appearing in a 1490s outbreak, caused severe symptoms and often death within a few months of contracting the disease. Fallopio's treatise is the earliest uncontested description of condom use: it describes linen sheaths soaked in a chemical solution and allowed to dry before use. The cloths he described were sized to cover the glans

 of the penis, and were held on with a ribbon. Fallopio claimed that an experimental trial of the linen sheath demonstrated protection against syphilis.

After this, the use of penis coverings 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 iustitia et iure (On justice and law) by Catholic theologian Leonardus Lessius

 were made out of intestines and bladder. In the late 15th century, Dutch traders introduced condoms made from "fine leather" to Japan. Unlike the horn condoms used previously, these leather condoms covered the entire penis.

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 inconvenience, 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" (bladder or intestine softened by treatment with sulphur and lye

). They were sold at pubs, barbershops, 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 sexual education.

1800 through 1920s

The early nineteenth century saw contraceptives promoted to the poorer classes for the first time. Writers on contraception tended to prefer other methods of birth control. Feminists of this time period wanted birth control to be exclusively in the hands of women, and disapproved of male-controlled methods such as the condom. Other writers cited both the expense of condoms and their unreliability (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.

Legal obstacles to manufacture and promotion of contraceptives were passed in many countries. Still, condoms were promoted by traveling lecturers and in newspaper advertisements, using euphemisms in places where such ads were illegal. Instructions 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 nineteenth century the condom was the Western world's most popular birth control method.

Beginning in the second half of the nineteenth century, American rates of sexually transmitted diseases skyrocketed. Causes cited by historians include effects of the American Civil War

, and the ignorance of prevention methods promoted by the Comstock laws. To fight the growing epidemic, sexual education classes were introduced to public schools for the first time, teaching about venereal 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; the medical community and moral watchdogs considered STDs to be punishment for sexual misbehavior. The stigma on 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 1800s. Early twentieth century experiments by the American military concluded that providing condoms to soldiers significantly lowered rates of sexually transmitted diseases. During World War I

 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, condoms sales doubled in the 1920s.

Rubber and manufacturing advances

, it eliminated the fire hazard previously associated with all condom manufacturers. 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 semiskilled workers. Throughout the decade of the 1920s, advances in automation of 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. The skin condom, now significantly more expensive than the latex variety, became restricted to a niche high-end market.

, 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 be utilized 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 debut, but condoms remained a strong second. The U.S. Agency for International Development

. 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 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, and the first custom sized-to-fit condom, called TheyFit, introduced in 2003. Worldwide condom use is expected to continue to grow: one study predicted that developing nations would need 18.6 billion condoms in 2015. For the boom of the condom industry, it appears there is no end in sight.

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.

A variety of Latin etymologies have been proposed, including condon (receptacle), condamina (house), and cumdum (scabbard or case). It has also been speculated to be from the Italian word guantone, derived from guanto, meaning glove. 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." 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 prophylactics, or rubbers. In Britain they may be called French letters. 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 flavoured 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.

, 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. Most commonly the Pearl Index

s.

The typical use pregnancy rate among condom users varies depending on the population being studied, ranging from 10–18% 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
Spermicide

Spermicide is a substance that kills spermatozoon, inserted vaginally prior to intercourse to prevent pregnancy. As a contraceptive, spermicide may be used alone....
) for greater protection.


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 might be given incorrect information on what lubricants are safe to use with condoms, mistakenly put the condom on improperly, or simply not bother to use a condom.

In preventing STDs

, in both men and women.

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. The primary effectiveness issue with using condoms to prevent STDs, however, is inconsistent use.

Condoms may also be useful in treating potentially precancerous cervical changes
Cervical cancer

Cervical cancer is malignant cancer of the cervix uteri or cervical area. It may present with vaginal bleeding but symptoms may be absent until the cancer is in its advanced stages....
. 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. 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.

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, 1–2% of women will test positive for semen residue after intercourse with a condom. "Double bagging," using two condoms at once, also increases the risk of condom failure.

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

Human penis size refers to the length and width of human male genitalia. Interest in largerpenis sizes has led to an industry devoted to penis enlargement, which has given rise to much e-mail spam....
, 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. 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.

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. 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

 reported clients sabotaging condoms in retaliation for being coerced into condom use. Placing pinholes in the tip of the condom is believed to significantly impact their effectiveness.

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.

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". (While intended to provide extra protection, double bagging actually increases the risk of condom failure.)

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 unrolled over the erect

 penis. It is important that about 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.

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.

Collection condoms are made from silicone or polyurethane, as latex is somewhat harmful to sperm.

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.

ism, may use collection condoms with holes pricked in them.

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.

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.

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. 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.
