Not all trans people seeking vaginoplasty are suitable for penile inversion. To be able to perform a penile inversion surgery, you must have a penis with minimum dimensions (it must measure more than 12 centimeters stretching the skin of the penis and counting from the peno-pubic angle to the tip of the foreskin) and a good quality of the penile skin. In any case, it will always be the surgeon who will assess all the circumstances, as well as the person’s medical history and the suitability of the technique to be used in their case.
