Can pre-ejaculation before the white semen cause pregnancy?

Yes, pre-ejaculation fluid, often referred to as "pre-cum," can potentially lead to pregnancy. While this fluid itself does not contain sperm, it can pick up sperm left in the urethra from a previous ejaculation. If this happens, the sperm can be transported into the vagina during intercourse, which could lead to pregnancy.

It's important to note that the likelihood of pregnancy from pre-ejaculation is generally lower compared to ejaculation, but the risk is still present. To effectively prevent pregnancy, it's advisable to use contraception consistently and correctly.
