Can you get pregnant from pre-sprem?

No such thing as pre-sperm, I think you mean precum in which case - YES, YOU CAN!

Yes! You can get pregnant from precum. (The sticky, clear substance that comes out of a penis when a guy is excited and before he cums. Looks a bit like raw egg white)

Precum is a fluid coming from the penis and is produced by the prostate and a few smaller glands that are situated in the body of the penis.

They produce clear slimy liquid called precum whose main purpose is cleaning the urethra (the tube running through the penis that urine comes out of) from any bacteria or the leftovers of urine.

Precum is also a lubricant that is used for lubrication of the glans and foreskin during the intercourse.

Depending on the person precum may or may not contain small amounts of sperm and the chances of pregnancy are small but, since in theory, only one sperm is enough to get a woman pregnant there’s still a chance that the pregnancy will happen.

It would be the safest to use condoms during the entire duration of sexual intercourse and ensure that no precum or sperm gets near your vagina either directly or from your fingers.

PS If the guy was really excited, it is almost certain that some precum would have leaked from the tip of his penis even if it was just a very small drop.

Be safe
