Description:

What are the specifications of condoms? What are the sizes of large, medium and small? (diameter)

Please tell us about the familiar condoms of famous brands at home and abroad, their advantages and disadvantages, and their approximate price.

Analysis:

Condom specifications can be divided into four types according to the diameter of the opening. The opening diameter of 35mm is large (about 11MM in circumference and 55MM in width), 33mm is medium (about 14MM in circumference and 52MM in width), 31mm is small (49MM in width) and 29mm is extra small.

as for the length, there is no exact standard for both east and west to reserve a large space.

Circumference is of great importance. For example, when Chinese people travel to Europe and America, if they accidentally buy condoms of local size, they will often feel loose and uncomfortable to wear. Therefore, if they want to be considerate, it is safer to buy products of local specifications in advance, so as not to fall into the * * * on the way to work, and they have to find an obstetrician to take them out, which will not only spoil the fun, but also add trouble.

most people don't know that condoms are divided into different sizes, because according to our national standards, only medium (standard) condoms can be produced, so none of the seven major domestic manufacturers have small condoms. Because condom production has a tolerance of 2cm and has greater flexibility, standard condoms can meet the needs of most people. However, a small number of people have different needs for condom size because of individual differences in reproductive organs. If the condom is too large, it will easily overflow during sexual life, thus reducing contraceptive efficacy and increasing the possibility of infectious diseases. In addition, too large condoms will also affect the feeling of sexual life and dampen men's self-confidence. However, if condoms that are too tight and narrow are used frequently, the genitals will suffer from ischemia and poor blood circulation, and the tissues and nerves will be deprived of oxygen, which will further damage the cavernous body. In severe cases, it will cause induration and lead to impotence. At present, there are quite a lot of people who need small condoms in China. A few years ago, there were condoms without packaging and brand, which were claimed to be OEM in Southeast Asia, but they were actually three products.

At present, the only choice for the small condom produced by Zhengchang is the Bello small condom of Guilin Hengbao, a Sino-US joint venture. Guilin Hengbao also has a "romantic poem" tight condom, which is between medium and small, with a width of 51mm and a circumference of about 12mm.

large condoms are also available in the domestic market. They are made in Guilin, Australia.
