Femininizing gender affirmation surgery includes the creation of external female genitalia such as a new clitoris, labia, and vagina with removal of the glans and urethral remnants and full corpora cavernosa. We evaluated the possibility of using preserved cavernosal bodies with glans and urethral remnants for potential live-donor penile transplantation. Between March 2021 and February 2023, penile microvascular dissection followed by gender-affirming vaginoplasty was performed in 41 patients aged 18 to 57 years (mean 30.5 years). The mean follow-up was 15 months (ranging from 6 to 26 months). The removed penile entities were properly measured. The corpora cavernosa were completely preserved in all cases; the length of remaining anterior urethra ranged from 12.70 cm to 16.40 cm, while the mean glans remnant volume was 85.37% of the total volume. All patients reported satisfactory results after gender-affirming vaginoplasty. Microvascular penile dissection in gender-affirming vaginoplasty is simple and safe, suggesting a good possibility of using the full corpora cavernosa, glans, and anterior urethra remnants for live-donor penile transplantation.
