At the beginning of the 20th century, with the development of latex technology, the production technology of condoms also improved, but its thickness was 0.06 millimeters, which often made couples unable to fully enjoy themselves. In 1949, the Japanese were the first to develop a "ultra-thin" high-quality condom with a thickness of only 0.02 millimeters. Not long after, Russian manufacturers were ingenious and produced condoms with many tiny latex particles or ridges in a threaded shape on the surface.
Condoms come in a variety of colors, including red, pink, light blue, light purple, goose yellow, black, or transparent latex primary colors. According to reports, Japanese people prefer black, Haitians prefer transparent color, Kenyans prefer red, while Chinese people mostly use latex as the primary color, and "colored" is still rare.
In recent years, various types of abnormal condoms developed by manufacturers have brought new feelings to couples' lives. For example, a new type of condom produced in the United States has a much smaller rubber ring diameter at the opening than the condom body, aimed at effectively preventing the penis from contracting due to blood reflux. There are also variant condoms with thorns and larger particles placed in different parts, which are inherently soft and generally do not damage the vagina. Some condoms are covered with about 1-inch long "needles", which are suitable for middle-aged and elderly women with excessively loose vagina after childbirth, as well as those suffering from frigidity.
Recently, there has been a type of artificially elongated condom on the market, with a head made of soft rubber and a body length of about 15 centimeters. This type of condom can meet certain sexual and psychological needs of some men and women.
Today, condoms have added many new functions to contraception and prevention of sexually transmitted diseases.
Some women produce antibodies against sperm, leading to rejection of the sperm and eggs and infertility. If the man uses a condom for a period of time and the antibodies in the woman's body gradually disappear, and then takes off the "coat", it is possible to conceive and have offspring. Therefore, condoms have become "pregnancy promoting condoms" among these people.
According to reports, couples who use condoms have a significantly reduced incidence of cervical cancer in their female partner, and their cancer prevention effect has been recognized in the medical community. At this point, the condom became a "cancer prevention condom" again. In order to fulfill the "multifunctional" function of condoms, drug-containing varieties have emerged. In 1975, the British first introduced condoms using spermicides as lubricants. Then, some American manufacturers successively launched condoms containing sulfadiazine silver or iodine, as well as other antibiotics, to suppress HIV, Treponema pallidum, Neisseria gonorrhoeae and herpes virus. Some manufacturers have also developed condoms containing local anesthetics to help men treat premature ejaculation.
