Condoms have a success rate of over 98% when used correctly and only 85% when used incorrectly.
The use of condoms can directly prevent sperm from entering the female vagina, thus preventing the combination of sperm and egg, and the success rate of contraception is very high, generally up to 95%.
A few women take the chance of combining condoms with safe periods, believing that safe periods should not be used, which will increase the chances of pregnancy. There are also women who think that they will not get pregnant without ejaculation, so they only bring it when they ejaculate, and before ejaculation there is already a small amount of sperm that enters the female vagina along with the prostate fluid, which will lead to a decrease in the rate of condom contraception.
The use of condoms must be used correctly in order to make contraception successful and prevent unwanted pregnancies from occurring.
