I was reading up on some things and I heard this-> There is a very small chance that "pre-ejaculate" can cause a pregnancy because sperm is not formed in this fluid. The only way sperm gets into this fluid is if there is sperm in the shaft... then this "left over" becomes very high in contrast to the small amount of fluid. This happens only if the man has had sex (or masturbated) earlier that day. Urine would clean this out.

Now, that's what I read from some website I found while googling. I was just wondering if anyone else had heard of this. Is there any trueth in this?

Yes, pre-ejaculate can cause pregnancy from what I have been told.

Yes, pre-ejaculate can and will cause pregnancy. The fluid comes from a glad called the bulbourethral gland which produces sperm.

All the pre-ejaculate does is lubricate the penis prior to ejaculation. It does contain sperm.
