Precum and pregnancy

01/08/2007

Question:

I was wondering what are the chances of a woman becoming pregnant from precum? I`ve heard so many different things from the chances are very high to that they are very low. Like what percentage is it possible to become Pregnant from precum alone?

Answer:

So called, "precum" can and often will contain sperm. It only takes one to cause a pregnancy. I can't give you the rates, but failure to prevent pregnancy with the withdrawal method is 20%. Some of these could be related to the sperm in the "precum" that escapes before ejaculation, before withdrawal.
