Condoms (also known as condoms, sanitary condoms, condoms, and sometimes called wishful condoms in Malaysia and Singapore) are non-drug forms of preventing pregnancy. They are mainly used to prevent the combination of human sperm and eggs during sexual intercourse. Prevent pregnancy. In addition, condoms also have the function of preventing the spread of sexually transmitted diseases such as gonorrhea and AIDS (HIV), so they are also called condoms. Today's condoms are usually made of natural rubber or polyurethane. As a contraceptive tool, compared with other contraceptive methods, condoms are easy to use and have no side effects. The contraceptive success rate is generally 97%. Specially trained users can achieve a contraceptive success rate of 98%.

Packaging: The outer packaging should at least include condom specifications (such as color, tip shape, etc.), nominal width, name of the manufacturer, wholesaler or seller, expiration date, and reference mark of the manufacturer (such as batch number, etc.) , storage guide, condom models, etc.

Time: Some people think that, like food, the fresher the condoms, the better. actually not. The newly produced condoms are stored in sealed packages after adding lubricants. At this time, the chemical properties of latex determine that their elasticity and texture are relatively poor. Generally, after six months to one year of storage, the latex will undergo a certain degree of physical or chemical reaction with the lubricant. At this time, the condom will reach its optimal state in terms of texture and elasticity.

Generally speaking, condoms that are 1-2 years old from the factory are the most comfortable to use, while condoms that are more than 3 years old tend to become brittle and have a slightly astringent texture. At the same time, the lubricant added inside is almost absorbed by the latex. The lubrication effect will be greatly reduced.

Things to note when using condoms

1. For couples who use condoms for contraception, it is best to prepare 1 or 2 kinds of anti-pregnancy drugs to prevent them from being helpless and overwhelmed after the condom breaks, causing mental stress.

2. It is very beneficial to use condoms and contraceptive cream together. Even if the condom breaks, the contraceptive cream can still have a contraceptive effect.

Why do condoms fall off in the vagina?

There are two reasons why a condom falls off in the vagina: one is that the condom used is too large; the other is that the man fails to pull out the penis and the condom from the vagina in time after ejaculation, causing the penis to shrink and cause the condom to fall off. The cover comes off.

What are the reasons for failure to use condoms? How to avoid it?

1. Accidental breakage during sexual intercourse: for example, excessive sexual intercourse; nails or rings accidentally scratching the ultra-thin condom, etc.

2. The condom model is inappropriate. Condoms that are too large or too small can easily fall off in the vagina or cause rupture during sexual intercourse, allowing semen to flow into the vagina.

3. The condom was not carefully checked before use, and a condom with leaky holes was used.

4. The air in the small sac at the front end of the condom is not squeezed out before wearing the condom. Therefore, the pressure in the sac increases after ejaculation, causing the condom to rupture and the semen to flow out.

5. After ejaculation and before the penis shrinks, the condom and the penis are not withdrawn from the vagina in time. After the penis shrinks, the semen overflows from between the penis and the condom into the vagina.

6. Some people are afraid that condoms will affect their sex appeal, so they do not wear a condom at the beginning of sexual intercourse. They then pull out the penis and wear a condom when they are about to ejaculate before the climax of sexual excitement. This will not have a contraceptive effect. Because before a man ejaculates, a small amount of sperm flows into the vagina along with the urethral mucus. Sometimes even if you subjectively do not want to ejaculate before the penis is withdrawn from the vagina, a small amount of semen will be ejaculated unknowingly, resulting in contraceptive failure.

7. Improper lubricant use: It has been observed that if mineral oil and vegetable oil such as Vaseline, ordinary lotion, etc. are applied to the surface of the condom, the strength of the latex condom will be weakened within 5 minutes.

8. Improper storage: Condoms will lose their strength when exposed to strong light, high heat, moisture and ozone.

Therefore, choose a condom of the appropriate model, check carefully before use, and master the correct usage method. If you find that the condom breaks or falls off in the vagina during use, you should stop sexual intercourse and remove the condom from the vagina. Then change to a smaller size condom and continue having intercourse. If the condom falls off during or after ejaculation, remove the condom from the vagina immediately to avoid contraceptive failure.
