This reminds me of the time I went to give my sample. I checked into the office, and the nurse looked at me, looked at my (Asian) wife, and then reached into her bottom drawer and pulled out a DVD of porn starting some Asian girls (I was not offered a choice or selection).
I was then given a cup and shown to my room. In the middle of the room was a very uncomfortable hospital chair covered in one of those pads that they put down that absorbs liquids to keep it sanitary. In the front of the room was a 20 inch tube TV/DVD combo (this was in 2013, long after the advent of flat screen TVs, so this TV was at least 10 years old). Hanging off the TV was a crappy pair of headphones.
To the left, a rack of about 25 porno mags of every kind of kink.
I was told to lock the door and then knock when I was done so the sample could be collected.
Not exactly the most conducive environment for producing that sample.
I believe the colloquial term is "pee pad."
