Can a little bit of my husband's sperm leakage at the vaginal opening cause pregnancy?

Patient's question:

No

Doctor's answer:

Generally speaking, to get pregnant, the male's sperm must be inserted into the female's vagina. During sexual intercourse, it is inevitable for a man to have some secretions when he is excited. These secretions will carry a very small amount of sperm into the vagina, which can also lead to pregnancy, but the chance of such pregnancy is relatively low.
