I have to say that I agree with atlasman to some extent on this one. I can relate several experiences in recent years where deer either paid no attention to where I urinated or were actually curious about it.

Now, I am not saying that I would use it as an attractant but I do not think it has the negative affect on them that everyone believes. However, as someone stated above, that is going to vary somewhat from individual to individual and from diet to diet.
