Condoms, also known as condoms, are thin film condoms made of high-quality natural latex. Condoms are used for contraception because they can effectively collect semen ejaculated during sexual intercourse, prevent sperm from meeting eggs and achieve contraceptive effects. Therefore, condoms belong to barrier contraception methods. Condoms have been used for contraception for at least 250 years and are the most widely used traditional male contraceptive method.
Condoms have a longer history of preventing sexually transmitted diseases, at least more than 400 years. Because the rubber film of condoms can effectively shield AIDS virus, it is currently recognized as an effective means of preventing sexually transmitted diseases and AIDS, and has been widely promoted and used by governments around the world. Although condom products are small, they play a dual role in controlling the population through contraception and preventing sexually transmitted diseases to protect the physical and mental health of people of childbearing age.
The mechanized production of condoms in China began in the mid-1960s. After more than 30 years of development, it has not only formed today's large-scale production - seven nationally designated condom production factories with an annual production capacity of 3 billion to 3.2 billion units, but also greatly improved product quality, producing high-quality condoms of different sizes, thicknesses, shapes, textures, and colors, At the same time, a certain number of products are exported to foreign countries every year. Types and purchase of condoms
1. There is no clear regulation on the product classification of condoms. Generally speaking, according to the nominal width of condoms, they can be divided into three types: large, medium, and small. A condom with a nominal width of 55 millimeters is equivalent to the previous specifications used Φ 35 or larger condoms; A condom with a nominal width of 52 millimeters is equivalent to Φ 33 is a medium size condom; A condom with a nominal width of 49 millimeters is equivalent to Φ 31 is a small condom. If a larger condom is used, it can easily slip into the vagina, causing semen leakage and leading to contraceptive failure; When a condom is too small, it not only limits the maintenance of an erection, but also easily leads to condom rupture and accidental pregnancy. Therefore, when choosing condoms, one should choose a product with a nominal width that is suitable for oneself.
2. According to the thickness of the condom, it can be divided into regular, thin, and ultra-thin types. The so-called thickness refers to the single-layer wall thickness of a condom, generally ranging from 0.04 to 0.07 millimeters, with the thinnest being 0.03 millimeters.
The Japanese are pioneers in producing ultra-thin condoms, and they also enjoy using thin condoms. Americans often use thick walled (0.05-0.07) condoms. Some commercially available condoms have a nominal ultra-thin thickness of 0.02 millimeters, but in reality, they cannot reach this thickness after testing. Ultra thin condoms can reduce the sensation of foreign objects during sexual intercourse, while thicker condoms can increase the anti rupture safety factor during use. If using ultra-thin condoms, you should choose high-quality brand products.
3. The shape of the condom is cylindrical, which can be divided into - A. Ordinary type (smooth or flat): there is a seminal vesicle at the top, and the body is smooth; B. Tip swelling; C. Tight type: 1 to 4 twisted sections are made on the body of the condom.
From the surface processing of the condom body adhesive film, there are two types: granular and threaded. Granular type can be divided into large and small particles. Rib pattern is also known as ring pattern. This processed condom can more or less increase irritation to the vaginal wall and improve the quality of sexual life. The above two types of condoms are often referred to as allotype condoms.
5. Lubricating condoms can be divided into silicone oil condoms and water-soluble condoms depending on the lubricant used. The initial production of rubber condoms did not have lubricants, and excessive dryness often caused rupture of the condom membrane or damage to the vaginal mucosa. Americans first applied lubricants such as glycerol and ethylene glycol on condoms, and began using silicone oil in 1960. The condoms produced in China in the early years used talcum powder as a lubricating and isolating agent, but were eliminated due to the frequent occurrence of chronic cervicitis and skin allergies caused by talcum powder. Since the 1980s, China has been using methyl silicone oil lubricants, which not only have lubricating effects but also have no irritating effects, are both hygienic and applicable. In recent years, water-soluble lubricant condoms have emerged in the Chinese market.
6. Colorful condoms. Condoms impregnated with latex should be transparent, colorless or light milky white. Since the Japanese first added color to condoms in 1949, various countries around the world have successively introduced various colored condoms such as black, red, blue, green, and yellow. At present, there are also colored condoms sold in the Chinese market. The introduction of colored condoms is not only to improve some people's aversion to condoms, but also to increase their attractiveness. People can choose to use condoms of different colors based on their preference for color or their mood at the time.
7. Fragrant condoms. In China, this is a type of condom that has been introduced since the early 1990s with various spices added. The types of spices added include rose fragrance, osmanthus fragrance, etc.
8. Medicated condoms. This is because non phenylether spermicide, anti-inflammatory drugs, sexual stimulation retardants, erectile aids, etc. are added to the condom, which is called a dual safe, drug type, and delayed type condom, and is collectively referred to as a drug type condom.
9. According to the different sealing packaging materials, condoms can be divided into plain and hardcover. Simple condoms are packaged with plastic film, which has poor sealing and light resistance; The hardcover condom is packaged with double-sided or single-sided aluminum foil, which has ideal light resistance and sealing performance. Faced with a variety of condoms in the market, what kind of products are good to choose?
Firstly, well-known brands produced by qualified enterprises should be selected; Secondly, it is necessary to carefully check the product information marked on the product packaging, such as the manufacturer, production date, production batch number, product type, and nominal width. Thirdly, it is important to pay attention to purchasing condoms that are within their intended use period, with a nominal width suitable for oneself, at a moderate price, and of a type that individuals prefer. In short, your choice largely determines your health. Choosing the most suitable one for oneself is the best.
