Scrotal skin does shrink to some extent over the years... but suporn uses some sort of device/machine, I don't know what it's called, to stretch the scrotal graft and increase the surface area. This is why he is able to achieve the extra depth, and this is also the reason why the recovery takes twice as long, and why you need to follow different dilation regimen compared to with other surgeons. In case he will think scrotal skin graft won't be enough, he will take a skin graft for groin area.. Don't worry, you will have adequate depth. You definitely choosed the right surgeon.
