I dont think they can determine gender, unless the female is like pregnant or something, and I doubt they would do checks on stuff like that anyways. I would at least use urine from a human cause other animals could have way different levels of certain chemicals than humans which would make it obvious that not human possibly.

Can gender be determined by urine can gender be determined by urine. the only 2 clean souls i know are my sis and my bf. of course i cant ask my sis if she'll piss for me cuz she'll rat me out. my bf said he would do it. but he said gender can be determined. is this true?
