There is no chance of getting pregnant without internal fertilization. Some men think that if they take the method of extracorporeal ejaculation for contraception, as long as they don’t ejaculate inside the vagina, they won’t make women pregnant, but this is not correct. If it is in the ovulation period, although not ejaculated in the vagina, still may let the woman pregnant, because although there is no subjective ejaculation feeling, but in the precursor force of semen prostate fluid, there are still a small amount of semen will enter the vagina of the woman. If it is ovulation, sperm and egg may meet in the fallopian tube to form a fertilized egg to make a woman pregnant, so extracorporeal ejaculation or no ejaculation, is not a safe method of contraception, you should take condoms or oral contraceptive pills to minimize the probability of pregnancy, to avoid unwanted pregnancy.
