The chances of getting pregnant without internal ejaculation are not very high, ranging from 3% to 5%. If you don’t want to get pregnant, not ejaculating internally is not a safe contraceptive because there is a possibility of pregnancy after all. A small amount of prostate fluid is produced before ejaculation. Prostate fluid has the effect of lubricating the vagina, but it will contain a small amount of sperm. A small amount of sperm will enter the uterine cavity through the endocervix and then travel through the fallopian tubes to combine with the egg discharged from the ovaries to form a fertilized egg which can cause an unwanted pregnancy. For women who have had children, it is better to use IUD to prevent pregnancy, which is safer. If a woman who has not had children wants to get pregnant after the IUD, she will need to remove the IUD, which will cause some damage to the uterus, and the male partner can use condoms to prevent pregnancy.
