What is the chance of pregnancy when wearing a condom?

Wearing condoms is a common method of contraception. Compared with taking pills or wearing rings, wearing condoms is simpler and does not bring any adverse effects to the human body. Therefore, it is still quite popular. However, sometimes people put on condoms halfway through sexual intercourse. So what is the chance of pregnancy when putting on condoms halfway through? Let's introduce it in detail below.

What is the chance of pregnancy during intercourse?

Generally speaking, if condoms are not used throughout sexual intercourse, there is still a small chance of pregnancy. Because during intercourse, a small amount of sperm may enter the female vagina in the secretions caused by sexual excitement and cause pregnancy. It is recommended that you use an early pregnancy test two weeks after having sex to rule out the possibility of pregnancy.

Although condoms are easy to use and have few side effects unless you are allergic to them, their success rate in preventing pregnancy is generally 85%. That is to say, the chance of getting pregnant with condoms is as high as 15%. However, data shows that if condoms are used correctly, the chance of pregnancy can be reduced to 3%.

The reason why the chance of pregnancy is high when wearing a condom is due to the following reasons: wearing the condom too late; taking off the condom too early; fully unfolding the rolled condom before putting it on; not leaving a certain amount of space for semen; not emptying the air at the front of the condom, etc.

If the condoms are of reliable quality and used correctly, their contraceptive rate can reach over 95%. A few condoms may have extremely tiny holes on the front end that are difficult to see with the naked eye. The diameter of the sperm tip is 3 microns, which can easily allow sperm to penetrate. In addition, condoms should be put on after the penis is erect before sexual intercourse. After ejaculation, pinch the edge of the condom with your hand before the penis softens, so that it and the condom can be removed from the vagina to prevent semen from overflowing from the base of the penis. According to surveys, a small amount of semen will overflow from the base of the penis in about 65-75 out of 100 times of sexual intercourse using condoms. Even if the amount of leaked semen is small, it may still make a woman pregnant.

There is a chance of getting pregnant while wearing a condom during intercourse, but it is not high. Sometimes semen has already overflowed before ejaculation. If this happens, the chance of pregnancy is relatively high. Depending on individual circumstances, there is definitely a certain chance of getting pregnant while wearing a condom.

The standardized use of condoms can indeed increase the contraceptive success rate to 98%, but we cannot guarantee that we can put on the condom correctly every time. If operational errors or improper use occur, the success rate of contraception will be greatly reduced.
