I don't think each human and his or her individual scent of: soap, toothpaste, clothes washing detergents, individual's generated bacteria including that of the mouth, shampoo, gasoline, kitchen smell of cooked food, leather boots, individual dwellings' own smells that are absorbed by clothes, etc... is identifiable in human urine. I think the aforementioned smells are not passed on in our urine.
And, I don't think deer have the "cognizance" to smell human urine and ID it as urine from a human. I don't think the impurities in human urine alarm deer.
I do think however, that if you could perform a negative stimuli when a deer smells human urine where human association or a connection between urine and humans is negative, a response would no doubt be learned by that individual deer.
Bottom line, I let'er rip and I don't worry about my pee and noted biologists have influenced my decision.
I've often wondered if I ate loads of asparagus the night before my hunt, what kind of reaction would I get if I peed all around my stand??
