What are the key factors to consider when choosing a condom? What should be noted when using a condom

Condoms (also known as condoms, sanitary condoms and condoms, sometimes called Ruyi condoms in Ma Xin area) prevent pregnancy in the form of non drugs. They are mainly used to prevent the combination of human sperm and eggs during sexual intercourse and prevent pregnancy. In addition, condoms can also prevent the spread of gonorrhea, AIDS (HIV) and other sexually transmitted diseases, so they are also called condoms. At present, condoms are usually made of natural rubber or polypropylene ester. As a contraceptive tool, condoms are more convenient to use and have no side effects compared to other contraceptive methods. The success rate of contraception is generally 97%, and specially trained users can achieve a success rate of 98%.

Packaging: The outer packaging should include at least the set specifications (color, tip shape, etc.), nominal width, manufacturer, wholesaler or seller's name, expiration date, manufacturer's reference mark (batch number, etc.), storage guide, set model, etc.

Time: Some people believe that the fresher the condom, the better. This is not the case. Newly produced condoms are stored in sealed packaging after adding lubricant, and the chemical properties of latex determine poor elasticity and texture. Generally speaking, after six months to a year of storage, the latex and lubricant have a certain degree of physical and chemical reaction, and at this time, the texture and elasticity of the condom have reached their optimal state.

Generally speaking, condoms that have been shipped for 1-2 years are the most comfortable to use. Condoms that have been shipped for more than 3 years are prone to becoming brittle and have a slightly astringent texture. At the same time, the lubricant added inside is almost absorbed by the latex, greatly reducing the lubrication effect.

Precautions for using condoms

1. It is best for couples who use condoms for contraception to prepare one or two anti pregnancy drugs to avoid feeling helpless and overwhelmed after the condom ruptures, causing mental stress

2. The combination of condoms and contraceptive creams is beneficial, as even if the condom ruptures, the cream can still have a contraceptive effect.
