I was born with one testicle undescended (i.e., still in my abdomen). Until I was 9-10, I never even knew that I should have two testicles in my scrotum. The urologist my parents finally sent me decided that the undescended testicle would not drop down (as everyone hoped it would) from the normal activity of a 10 year old boy ). For about four months, I had periodic visits to the doctor who would try to milk the testicle down. He would have me stand naked on a chair and then insert a finger through my scrotum into the hole (the same way they check for hernia).
After three such attempts across several weeks, there was no success. Since puberty was approaching, my doctor said it was time to do surgery to correct the situation. That summer, I was admitted to a hospital for surgery. That night, they gave me two enemas. I had never been given an enema by anyone except my mother, and I was embarrassed to have a nurse strip me down and put the nozzle in my ass. The next morning I was operated on. After waking up, I found that the testicle was in my scrotum. However, to make certain that it didn't get loose and rise into my abdomen, they had tied a string around it. Then they ran the string through my scrotum, and attached the end of string to a piece of adhesive tape just above my knee.
The hospital that I went to was also part of a medical school. So now I was visited every day or so by doctors, interns, and nurses to see how this was done. 4-6 hospital staff would walk in, and their leader would take the top bed sheet and pull it down to my feet. If I had on a hospital gown, they would pull that up so everybody could see the bandage over the cut through my abdominal wall to get to the testicle. In a sense, I felt that my penis and testicles were constantly on view - just as if I were an exhibit in a museum. While I sort of got used to it, I was always embarrassed and probably turned red the first few times if happened. To boot, there was one nurse in that ward who just couldn't get enough time looking at me. When ever she came in the room, I knew she was coming to pull down the sheet and look at me.
