Hi Brittany,
My opinion only would be to include something of the process of isolating spermatozoa from the diluting urine after being redirected to the bladder? It’s not like the testes creating the semen made them in the urine instead. The delivery mechanism (a muscle lapse?) didn’t close off the bladder to urethra track, causing the semen to be directed to the bladder. So it is an unusual collection point. Maybe try system Urine.retrograde semen in your submission?
I’m not sure if Regenstrief keeps track of all rejected terms; seems like 3M did try to get them submitted back in 2014-16 era.
