I can not stress enough to you to find a Genreal Surgeon to do it.
You go in for surgery and they put you to sleep and take care of everything then. No watching, smelling, or conversation with Dr.
You only have to wait a couple weeks to sample because it doesn't require the number of releases.
The incisions are in a different location and you don't have to sit on ice the next day.
Everyone who I have discussed mine with that had a Urologist do it wishes they would've known to go to Gen Surgeon.
