Hello Anon and thanks for your question.   Pre-ejaculate itself does not contain any sperm.  If he urinated since he last ejaculated, there is no sperm at all. Pregnancy is very uncommon from pre-ejaculate and the urethra would have to contain sperm at the same time. A woman would also have to be ovulating and engage in unprotected intercourse with ejaculation.

  The risk of pregnancy appears to be  little to none.

Best,
