There are many couples in life who like to use in vitro ejaculation to contraception. They feel that sperm ejaculates outside the body. Not only such a female vagina, sperm eggs are not combined, so they will not get pregnant. In fact, this is not the case.
In sexual life, men usually flow out of some semen before ejaculation, and the penis cannot be pulled out in time, resulting in a part of the semen ejaculated in the vagina when ejaculation, or before reaching the climax, a small amount of secretions enter the vagina. In the endIt can lead to the possibility of accidental pregnancy.
