Hi Harukahime
I hope your day is going well

I haven't had my SRS yet, but I will be next week at PAI. So, I can't comment about the experience of having the procedure yet, but I can say that the service and consulting from them has been amazing. There are a couple of threads out there about PAI, you might have to do a search or go back a little in the forum, but from what I remember I think they were all positive experiences. I haven't really found any negative reviews about them, and all of the ones I've seen have good things to say about them. They seem to be pretty consistent with their work and their facilities for recovery at the hospital are two reasons I chose PAI, among other factors. In terms of depth, I believe it ultimately depends on how much material you have to begin with. For most, they use the penile skin inversion/ and or scrotal graft, and obtain the standard 5-6 inches of depth. They also offer the sigmoid colon, but from my understanding they usually perform it in cases where someone is unsatisfied with the depth they received from a previous procedure or there wasn't enough material to perform the penile inversion. I think on their website they state that if you want more depth like over 8inches or so, you would have to get the sigmoid colon. Which is something to think about too. Anyways, I hope this was some help

I hope to start a thread about my experience at PAI soon, so once I start it I'll try to keep it updated.
Much Love,
Alessia
