I had a vasectomy done about 13 years ago, I was somewhere around low to mid 30's. My wife and I went to the urologist for the first consultation and he did an unexpected genital exam on me at the end. Went back a few weeks later on a Thursday afternoon for the actual procedure. A nurse called my name in the waiting room and took me back to an exam room and told me the doctor would be in soon. He came in and walked me back to the procedure room. He told me to take off my pants and underwear, have a seat on the standard exam table, and gave me a cloth sheet to drape over my lap/ legs. He left the room while I undressed and he returned a few minutes later. He had me lie back with my feet still dangling off the table. He placed a folded towel underneath my scrotum, lifted my penis, and shaved my scrotum with a metal safety razor. All the hair went neatly onto the towel, which he removed when he was done. He used some solution and cleaned and dried my entire crotch. He then took one thick hand towel, folded it length wise a couple of time, and placed it over top of my penis which was lying up on my stomach. Then took another unfolded towel and placed it on top of the other towel. Then a third towel was placed over my legs and under my scrotum. I thought this was brilliant, it completely covered my penis yet my scrotum was completely visible and accessible. The towels were also thick enough that if I did get a hard on during the procedure (thankfully I didn't) it wouldn't be completely obvious and in the way any.
Once i was covered, he scrubbed my scrotum with another solution, switched gloves, and got all his tools and instruments in trays situated onto the exam table. He was standing over top of me when he suddenly said "OK" in a loud voice. Instantly his nurse walks into the room and stands over me on the opposite side of the table. I thought this was a nice touch since it minimized my exposure to her. She never saw my penis the entire procedure, only my scrotum framed in white towels.
He used a small syringe to numb me at a few spots. In the middle of my scrotum, an inch or two below my penis, where he did the incision, I could barely feel the injection, just a slight pinch. Next he said he was going to numb the right side, I actually don't think I felt that at all. The two of them worked away and I felt nothing. The worst was when they cauterized the cord (or whatever it is they cauterize) and I could suddenly smell the burning. Yuck.
A little while later he said he was going to numb the left side. That's when things went downhill. The numbing injection hurt. When he started the procedure it hurt even more and I flinched. He gave me another numbing shot and it helped. But I could continuously feel tugging, pulling, and pinch every now and then. Like the left side wasn't completely numb. Half way through the left side, I feel a poke in my scrotum and the nurse suddenly said, "Oops". Of course, I freak out. That is not something you want to hear from somebody who is simultaneously holding my balls and sharp instruments in their hands. Apparently her name tag fell off and landed on my nuts. We all had a laugh and they finished and stitched me up. The nurse left and the doctor put a device similar to a jock strap on me (I've now learned it's called a suspensory). With me still lying down, he had me lift my legs a bit and strapped it on me. The pouch had a hole in it that my penis stuck out of. It felt really weird.
I had to wear that suspensory for a couple of days, and I never got used to it. I laid around with frozen peas on my nuts all weekend and went to work the next Monday. I was to ejaculate at least 10 times, using some method of birth control if we were having sex. Then I was to bring in 3 sperm samples for them to test. The samples had to be at least 48 hours apart. I was in a hurry to get that part over with so I took matters into my own hands... ? Within a few weeks I was given the all clear.
However, my left nut hurt terribly for 4-5 months. Very tender and sensitive. A dull ache. I described it to friends that it felt like someone flipped it with their finger. A couple of my coworkers were thinking of getting a vasectomy until I relayed my experience. Even to this day I get the same feelings in my left testicle. I've never mentioned it to any of my doctors. Not sure why, I guess I'm embarrassed by it or don't think it's worth complaining about. Still, overall, I'm 100% glad I had it done.
