Whilst the PhalloBoards is a
No-Silicone-Zone, the status largely applies to the use of a rigid silicone implant for enlargement (and not erectile dysfunction), as well as silicone filler injected in high volumes. Given the lack of anecdotal data from the forum as well as its experimental nature, I'm willing to permit this discussion. Besides, the few instances of silicone testicular enhancement I've seen have been decent (including work from different physicians).
I should note* however that I personally haven't endorsed or recommend any testicular or glans enhancement procedures (only girth and length), but that isn't to say they do (or don't) work.
@GrantJohnson
I appreciate you willing to post photos for validation, would you mind if I asked if you had "Befores" to compare them to as well?
Also, please understand that your performing physician isn't terribly popular around here, largely due to credible reviews spanning a decade on these forums (credible as in, actual before & after photos backing up their claims and other pertinent information that only real patients would have). I'm letting you know this (if you didn't already know) so as to prepare you for what could be skeptical or less-than-optimistic replies in the future. If you can handle that, you'll be fine here (Note* I will not tolerate any mean-spirited criticisms given the climate here re: said-physician).
Good luck and keep us posted.
[Edit: Well it turns out after my insisting that I'll ensure a welcoming environment (here and through private message), it appears he (GrantJohnson) has had a change of mind. I hope he reconsiders in the future, otherwise, this thread is now locked.
