The condom is Condom in English, named after its inventor, Joseph Condom, an English physician in the late 17th century. Condom, the royal physician to King Charles II of England, invented the condom, made from the appendix of a lamb, which was first cut to the proper length, dried, and then made soft with grease and bran until it became thin and rubbery. As a result of his invention, Condom was knighted by King Charles II and his invention was hailed as a “delightful invention”. However, historical sources show that Condom was not the originator of the condom, as similar contraceptive devices were depicted on artwork from ancient Egyptian and Roman times. These earliest condoms were made from animal bladders or fish bladders. For the origin of condoms, condoms are also called condoms, it has been used for hundreds of years, the early invention of condoms is not for contraception, but for preventing the spread of sexually transmitted diseases, so it is called penis condoms, condoms and so on. In modern times, due to the dramatic growth of the world’s population, the penis condom was used as a contraceptive tool for men, and was officially named “condom”. The condom is now the most commonly used male contraceptive. In 1492, Columbus’ sailors brought syphilis back to Spain from Haiti in the Americas, and a year later it spread to France, Germany and Switzerland. On the wings of love, syphilis swept across Europe, and 10 years later, the virus conquered the entire world. People reacted quickly to this. Gabriva Falubay (1523-1562), a professor of anatomy at the University of Padua in Italy, invented a condom made of a linen cover. Falubai claimed that the purpose of this invention, is to prevent sexually transmitted diseases, and secondly, is used for contraception. 1551 ~ 1562 years, he had a survey of 1,100 people of various types of use of such condoms, the results were satisfactory. Therefore, some scholars believe that the right to invent the condom should be attributed to Falubai. Early condoms, mostly made of linen or sheep intestine, were gradually replaced by latex condoms after entering the 19th century. The first latex condom, invented by Dutch physicist Dr. Arlette Jacob in 1883. The condom has been hailed as one of the 100 inventions of the 20th century that most profoundly influenced mankind, and it is celebrated because it is so simply and conveniently constructed, so inexpensive and popular that it is effective not only in achieving population control but also in preventing sexually transmitted diseases. According to scientific studies, consistent condom use reduces the risk of HIV transmission by 80% to 90%, and the risk of contracting chlamydia from never using a condom is 10.91 times higher than that of a consistent user. More experimental evidence also confirms the effectiveness of condoms for the prevention of other sexually transmitted diseases – gonorrhea and syphilis, genital herpes, condyloma and even hepatitis B. The overall effectiveness of condom use for STI prevention was 85.82%. Of course, the most effective prevention of STDs is self-discipline, adherence to monogamy, and reducing the number of sexual partners and premarital and extramarital sex. However, with the increase of sexual openness in modern society, not everyone can practice self-discipline in sexual behavior, and these people are the susceptible group of various sexually transmitted diseases, so it is especially important to promote the role of condom among them. STDs and AIDS have incubation periods, especially syphilis and AIDS, which can last for several years or even a dozen years. Therefore, when having high-risk sex with someone you don’t know, not only is there a risk of unplanned pregnancy, but there is also a risk of STD and HIV infection, and condoms are the last barrier to eliminate this risk.
