Condoms are non-drug forms of preventing pregnancy. They are mainly used to prevent human sperm and eggs from combining during sexual intercourse to prevent pregnancy. Today's condoms are usually made of natural rubber or polyurethane. Many people think that wearing a condom will keep them away from the term mom and dad! But, do you know? You can get pregnant even if you wear a condom! Let’s see why! The contraceptive mechanism of condoms is to prevent sperm and eggs from combining. But in fact, a small number of people's wives still become pregnant after using condoms. What are the reasons for condom use failure? How to avoid it? Common ones include the following:

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 After ejaculation and before the penis shrinks, the condom and the penis are not withdrawn from the vagina in time.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 Sometimes even if you subjectively do not want to ejaculate before the penis is withdrawn from the vagina, a small amount of semen will be ejaculated unknowingly, resulting in contraceptive failure.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. Use of improper lubricant: 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.

Before use, fill the cover with air and pinch the opening to check for air leakage. When using it, the gas should be exhausted, especially the gas in the small sac, so as to prevent the top from rupturing during sexual intercourse and ejaculation, resulting in contraceptive failure. After pulling it out, check again whether the condom is broken. If it is broken, remedial measures must be taken.
