Sperm eaten into the stomach will not cause pregnancy. Sperm can only get pregnant if it enters the vagina and combines with the woman’s egg to form a fertilized egg, which is the case. First of all, the prerequisite for pregnancy is that the woman has to have a mature egg, and during sex, the male sperm enters the woman’s vagina and combines with the mature egg to form a fertilized egg, and then there is a possibility of pregnancy. Sperm eaten inside the stomach will reach the stomach and will not combine with the egg, so there is no possibility of pregnancy. It is recommended to relax and pay attention to the hygiene of sexual life to avoid the occurrence of infection. If you don’t want to have a baby, you need to take contraceptive measures to avoid unwanted pregnancy.
