I have been trying to research the periotoneal vaginoplasty. It seems a small number of surgeries are being done as a sort of proof for use on transwomen in India. The gynocologist who developed the "laproscopically pull through periotoneal vaginoplasty" for women with Mullerian agenesis and those with CAIS seems was involved.
His studies showed normal vaginal like tissues forming from the periotoneal tissues by what he termed "progenator cells". For those women who received the surgery the big plus is no need for life long dialation to prevent tissues fusing or shrinkage as well as natal like secretions. He performed this on girls from 2003 to 2013 and followed up recently with them.
This gynocologist also originated transplant of ovarian tissues. For instance he developed removal of the outer egg carrying region before chemotherapy. Later the frozen tissue can be reimplanted. Patients have been able to ovulate and get pregnant after chemo.
So a place in India was supposed to have organized GCS for transgirls using him and other plastic surgeons. I am still trying to find out more about this. However the information I have gleaned so far is that no penile inversion was needed. They used penile and scrotal skin for the inner and outer labia. I can see this as a positive.
In normal penile inversion the skin must be streched in order to get the inverted penile skin down to the correct position. Then new openings have to be made for the ureathra and neoclitoris. With this other method the neoclitoris can be positioned under the natural hood like skin structure. Seems like less chance of pulling stitches with the skin not stretched so much.
I really hope this ends up being a viable option
