I agree with Reman.
School medicals happen in the most formative and vulnerable years of our life when we are going through puberty and for most feel shy about our naked body, (remember how you felt when you stood naked in front of a boy/girl friend for the first time. And all the emotional and physical problems like erections, periods, masturbation and for some sex that it brings. I can only relate what happen in my own school.
In hospital I had far more invasive exams but they seemed to be handed different and more anonymous,ere the only people at school that knew what I had done were the people I told . Back at school things were handled in a less private way in fact the medicals became an almost public event - a right of passage . Because I went to a school that was built in the 60's, the medicals had become an annual event and everyone had to have on, knew what happened and scared the newbie’s shitless with horrendous tales.
Your name was put on the school bulletin broad as to when you had to turn up and they were always held at the same time of year. An hour or so before your physical, several of the girls had to go to the changing rooms, have a shower and then change into our tennis kit (incredible short skirt and polo shirt). They could wear knickers, but could not wear a bra to school (I found out later so there were no marks on the skin). When it was my groups turn we had to walk the walk of shame to the headmasters office. Wearing sports clothes looked odd as if we were playing sport we would have gone straight outside, but being barefoot nailed it for us and everyone knew that not only were we going to the place where we would have to stand naked in front of adults, but that we were braless and what made it worst was well built girls like me bounced as they walked.
When you went into the room you had to hand the attending nurse your skirt (velco so it came off easier than a traditional school skirt).
The nurse took my weight. height etc.
The doctor then asked a lot of personal very questions which I got embarrassed about. She then did the normal checks, auscultating me, probing my tummy and tapping my back, the nurse then put a chair at the back of me and the doctor checked my feet.
After I was told to stand up, the nurse then reached out and told me to take my knickers off and hand them to her. They then looked me up and down which made me feel worse and then I had to walk up and down in front of them.
After that I got dressed and walked back to the changing rooms, and what made it worse was the people that walked pasted me knew what I had been through.
That said I wish I could go back and go through it all again.
