The study I saw was this,

Video and still cameras were setup on several scrapes containing 4 scents. The 4 scents were buck urine, doe urine, human urine and new car smell...that's right, new car smell.

The scrapes that were visited the most by both bucks and does were the ones containing buck urine and the ones containing human urine and the study states they were visited equally.

The scrapes containing doe urine and the ones containing new car smell were visited equally as well but not equal to the ones with buck or human urine in them.

Conclusion, buck urine is a better attractant then doe and they can't determine that human urine is in fact from humans.

That doesn't change my mentallity on being as scent free as I can be.
