When referring to having transperenial biopsies, markers, Space/Oar where the needles are put in area between anus and start of testicle area what is this area called?

I know when I had transperenial biopsies I was under anesthesia. When I had my markers and Space/Oar it was done transpernial but was not put under anesthesia. They did use a pre anxiety medication, numbing, and laughing gas. I also (and this is quite graphic) them lifting my testicles up and taping them up an away.

It was the fear what was being done versus any real pain that I expereinced. I had laughing gas (you take as need on your own there) bot do not remember laughing. When I made a comment to tech about not laughing he said that is not what you said a couple of minutes ago. So don't know if laughing gas brings you to another level of consciousness or awareness.

Even when done transperineal (markers, Space/Oar) the R/O ordered a smear test for specific antibiotic I would be put on.
