I work in a health science library and was shown the original article yesterday prompting me to look up an online version I could send people (thus here I am).

To answer some questions: There was a hole for the penis to go through so they could still try to get it on. ditto for a crap hole. When the underpants were too soiled they were changed for a fresh pair.

Really really really weird. I wonder if anyone working on it thought to themselves "Hey, I'm up to my ass in debt so I could have a PHd... and this is what I'm doing??"
