I'd have to see a more scientific study of the actual chemical makeup of doe hormones vs human hormones. I doubt the two are the same and I'm sure a buck wouldn't be confused by the two. Anecdotal evidence isn't conclusive as there could be any number of factors involved. Like huntinma's experiment: how does she know this wasn't a mock scrape, or that she didn't leave her HUMAN scent in addition to her female scent? I have heard people say that urinating, in general, in a scrape has positive/negative/no effect so which is true? Maybe it's just the urine itself that made the buck leave the scrape cold? Who knows?
