Transgender Reassignment Surgery

There are 4 types of SRS that are currently being done today
SRS with skin graft technique
The skin graft is used for the lining of the vagina instead of inverted penile skin. In most cases of this type of transgender surgery, the skin of the scrotum is the main source for the skin graft.
SRS with colon graft tecnhique (colon vaginoplasty) 
This is a procedure in which a section of the rectosigmoid colon is used and transplanted into the vaginal canal and can provide an adequate depth (between 7 and 8 inches ). Because the colon segment is highly vascular which allows for efficient blood supply and allows better healing towards scar tissue. This transgender surgery procedure is usually not considered for the first option for SRS as it is a more invasive procedure than other options.
Non-penile inversion technique
Non-penile inversion is a transgender surgery procedure of using inverted scrotal tissue instead of the penis ( penile -inversion technique ) The main difference between the non-penile inversion and penile inversion is that when using the scrotal tissue you usually have better depth because the scrotal tissue can be stretched easier than the penis tissue. ALthough, if you had procedures in the past that have affected the scrotal tissue such as removal of testicles than this can affect the procedure and depth.
Penile inversion technique
The penile inversion technique has been a transgender surgery procedure that has been around since the early 50’s and is the technique being used in the Western World. This technique is just what it sounds like; The penis is basically inverted and pushed inside the body. The skin of the penis is now the interior wall of the vagina. A labiaplasty is sometimes done to create a more feminized area of the outer vagina.
