Posted 12/3/2010 2:53 AM (GMT -6) I've just had a quick search through assorted sources for tips about what to avoid. 48 hours seems to be the consensus when it comes to sex/ejaculation. A couple of days would also seem about the norm for minor things like cycling, horse riding too. A DRE is a bit more of an interference so a couple more days. The big thing to avoid is the doc giving you the DRE first and then drawing the blood. It takes about 6 weeks for PSA to settle down after a biopsy. And BHP and other infections are a bigger influence still, and may take months to stop affecting the results.
