It is normal to get pregnant after intercourse, but ejaculation outside the body can also lead to pregnancy, although the chances of conception are low. The reason is that when ejaculation outside the body reaches the vaginal opening, the sperm will wander and can travel to the vagina, through the uterine cavity to the fallopian tube abdomen to meet the egg, and then return to the uterine cavity after fertilization and implantation and conception, and in some cases, ectopic pregnancy. It is recommended that women of childbearing age who do not want to get pregnant should use condoms for the following reasons: 1. the highest success rate of contraception; 2. to prevent the occurrence of sexually transmitted diseases such as gonorrhea, trichomoniasis, mycotic vaginitis, condyloma acuminata, AIDS, syphilis, etc.
