In the case of extracorporeal ejaculation, if you have intercourse at the time of ovulation, then you need to take Yutin as well. This is because even though it is an ejaculation, the man will secrete a lot of prostate fluid before the ejaculation, and the prostate fluid will contain a small amount of sperm. Once this sperm is left in the vagina, the sperm will pass through the cervix into the uterine cavity and reach the fallopian tubes where it will unite with the waiting egg to form a fertilized egg, and then pregnancy will occur. So despite the fact that ejaculation, it is clinically recommended to take the emergency contraceptive pill Yutin within 72 hours after intercourse to achieve the purpose of contraception, otherwise there is still the possibility of pregnancy. Extracorporeal ejaculation is actually an unsafe method of contraception. If you are not planning to get pregnant, it is best to use a condom throughout your sexual life to prevent pregnancy.
