How does a silicone injection for the scrotum and penis work?

I’m very green, low T since I was 15, kleinfelters syndrome, wondering about making my pre-puberty junk bigger but not ridiculous. Price, type of certified doctor to look for, questions I should be asking. Right now my scrotum looks like a golf ball was sliced in half and stuck to my shaft. I pump regularly and would like to know if it’s possible to get my scrotum to look pumped permanently and to have a penis that looks like it belongs with the size scrotum I’d get if it’s possible for me to do so.
