What is the possibility of getting pregnant with unprotected sex?

What is the possibility of a woman becoming pregnant after unprotected sexual intercourse where the man has been taken and after a certain time has been pulled back without a condom. The doubt is: are the sperms still inside the body of the penis even after a certain time?
Expert answer:

There is always the possibility of a woman getting pregnant when there is unprotected sexual intercourse. If urinating sperm will be eliminated together, very few become viable inside the body of the penis, however each relationship is a new relationship and there are always chances of getting pregnant in an unprotected relationship.
