A condom (pronounced /ˈkɒndəm/ (US) or /ˈkɒndɒm/ (UK)) is a barrier device most commonly used during sexual intercourse to reduce the likelihood of pregnancy and spreading sexually transmitted diseases (STDs—such as gonorrhea, syphilis, and HIV). It is put on a man's erect penis and physically blocks ejaculated semen from entering the body of a sexual partner. Because condoms are waterproof, elastic, and durable, they are also used in a variety of secondary applications. These include collection of semen for use in infertility treatment as well as non-sexual uses such as creating waterproof microphones and protecting rifle barrels from clogging.
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, most often made of polyurethane. As a method of birth control, 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—women whose partners use 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, primarily over what role they should play in sex education classes.
History
Before the 19th century
Whether condoms were used in ancient civilizations is debated by archaeologists and historians.[1]:11 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.[1]:17,23 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.[1]:60-1
In 16th century Italy, Gabriele Falloppio wrote a treatise on syphilis.[1]:51,54-5 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.[2][3] Falloppio'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.[1]:51,54-5[4] Falloppio claimed that an experimental trial of the linen sheath demonstrated protection against syphilis.[5]
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, who condemned them as immoral.[1]:56 In 1666, the English Birth Rate Commission attributed a recent downward fertility rate to use of "condons", the first documented use of that word (or any similar spelling).
