In the case of external ejaculation, the chances of pregnancy are clinically low, but there is a possibility of pregnancy because even in the case of external ejaculation, a large amount of prostatic fluid is secreted before ejaculation, and there will be a small amount of sperm in the prostatic fluid. Once the sperm is left in the vagina, it enters the cervix, then the uterine cavity and then the fallopian tubes, where it unites with the egg to form a fertilized egg, which will clinically result in pregnancy, so this method of contraception is a risky method. It is recommended that if you are not planning to get pregnant, it is better to use condoms for contraception during the whole process of sexual life, so that it will be safer. In addition, condoms must be inspected well before use to know whether they are broken or not before using them.
