Whether or not condom side leakage will lead to pregnancy should be discussed in the following situations: 1. To get pregnant, there must be enough sperms and normal eggs, even if the condom leaks sideways and more sperms flow into the woman’s vagina, the number of sperms or sperm content of these semen is too low, which may lead to the woman not getting pregnant. 2. If the condom leaks sideways and a certain amount of sperms and sperm motility are relatively good, it may lead to pregnancy. If the condom leaks sideways and the sperm count and motility of the sperm in the semen flow is relatively good, it is very likely that the woman will get pregnant when she encounters a normal egg. 3. Although the condom leaks sideways and a certain amount of semen flows out, it will not lead to pregnancy due to the lack of a mature egg.
