Had it done a few years back.
In short, it went like this;
After taping my nob to my belly Dr then sent my ball bag to sleep with some drugs, I think it must have been a needle but can't remember. He did warn I might feel some things going on.
He then spent about 10 mins chopping away at my ball bag and the contents. I did feel some things going on but no pain. He quarterised some bits, explaining as he did it the tubes have a knack of growing back.
He then told me that he wouldn't be stitching my sack up. Said modern technique is to just let it heel and there is less chance of infection. But to be very careful re keeping it clean and clean undercrackers etc. I think he said a few days and it should be good.
This I found alarming and when I did eventually remove the bandage there was indeed a 1 inch hole front and central in my nut sack! But as he said it did just heel up no bother.
Afterwards you have to go back with some jizz to confirm it worked.
Everyone always asks if it's made any difference and the answer is no. Same stinky jizz as before.
