Hasini I dont have any source , I just happened to know 2 girls in India who got this surgery , there were the only 2 trans girls to get this surgery in india , it was an experimental surgery, they got the surgery free , they were the guinea Pigs for the surgery. But both of them are unsatisfied, Their recovery has been difficult & long , & the Virginal girth is really small.
I have also Physically seen the results of the surgery of these girls, the Vagina looks much more natural & lubricated , But girth is really small hardly 2 fingers width.
