I can recall only one time that a measuring device was used in my testicles. It's kinda of a funny story.
I had some pain that resembled my hernia from about ten years earlier. I was afraid it was back. My doctor didn't want anything to do with checking me for a repeat hernia and sent me to a 'specialists'.
I walk into that specialist office, that was in the same building, but had been completely redone on the other side of the door. Every other office had the generic cookie cutter layout, design, color pattern than the next office. But not this 'specialist's' office! This one was easy better looking, better furniture and light fixtures. Better wall coverings. The works!
I check in and wait for about 20 minutes. No one else came in or left that office while I was there.
The nurse comes out and calls my name, I follow her back through the doors and that's her office. No hallway, no other doors leading to other parts of the wing. Weird set up.
She goes through my record and tells me to stand up and lower my pants and underwear. She watches me while sitting at her desk. She cleans her hands with a squirt of lotion/gel and puts on blue gloves. She had me standing there in front of the chair next to her desk, with my pants around my ankles and my shirt pulled up. She opens the drawer next to my thigh and did through and finds a measuring tape. She grabs a Lysol wipe from a bag of them and proceeds to clean the tape measure. I'm just standing there naked from my belly button to my ankles.
She grabs a very used notebook and opens to a clean page and begins to write in it. She then finds the lower numbers of the tape and wheels herself closer to me and measures my right testicle. She writes in the notebook, them measures my left testicle and then writes in the notebook.
She cleans the tape measure and puts it back in the drawer, then tells me to get dressed and leave the room.
She thought my testicles were the hernia!
