A member asked:

Anytime you have unprotected sex can you get pregnant if the sperm fertilizes an egg? can any sperm fertilize a mature egg?

A doctor has provided 1 answer

Yes: Usually an egg can be fertilized by sperm in 60 to 80% of the cycles, but only 15 to 20% of the time will implantation occur and subsequently yield a positive pregnancy test. Also not every sperm can fertilize the mature egg.
