A bunch of semi-formal studies have been done and they seem to show deer not associating human urine with humans or danger. One of the ones I read was by a biologist from the University of Georgia, Dr. Karl Miller., but I can't find a good link on it anymore. He said there is nothing in human piss that neccesarily says "a human pissed here" to a deer.
This is often a thread on bowhunting forums and some pretty successful (on mature bucks) veteran hunters are pro-pee. Lots of them piss in scrapes.
I've had deer spook at residual scent trails my boots left, I had a deer spook 2 weeks ago at spot I had tripped and landed flat out on my face walking in that morning in the dark (ouch)....but I've never had a deer spook where I've peed.
I'm firmly in the "they don't associate it with danger" camp. They sniff it, say "something pissed here" and get on with life.
