Pregnancy is also possible without a condom and with ejaculation, but the probability of pregnancy is relatively small, and if it is during a safe period, the probability of pregnancy may be less than 15%. However, if it is during ovulation, the probability may also increase accordingly, around 30%. If you don’t have the requirement to have children, it is better to take strict contraceptive measures, because there is a possibility that the sperm may be missed in advance by in vitro ejaculation. If the sperm missed in advance enters the vagina, enters the uterine cavity and unites with the egg there will be the possibility of pregnancy, both of which are possible if no good contraception is in place. If you are not planning to have children, you should use condoms to prevent pregnancy, or take short-acting oral contraceptives before the age of 40, or place an intrauterine device if you do not want to have children.
