PURPOSE OF REVIEW: The present study reviews contemporary literature focused on transplantation and tissue substitutes for the purposes of masculinizing genital gender affirming surgery. Additional background is provided for both topics to provide a more comprehensive understanding of the modern applications.
RECENT FINDINGS: Genitourinary vascularized composite allotransplantation has become a reality in recent years with several cases reported worldwide in cisgender men with promising reports of urinary and sexual function. A natural extension might be to apply these techniques to gender affirming surgery (GAS). Technical barriers include anatomic differences between vasculature supporting penoscrotal and vulvovaginal anatomy as well as size discrepancies between the corporal bodies which complicate the required anastomoses. Whether the smaller caliber of biologic female pelvic vasculature can support erection of a neophallus is another obstacle. Ethically, resource allocation, elective immunosuppression, society response to organ donation and gender identity, as well as the psychosocial safety of the patient given charged public opinion must all be considered.Tissue substitutes have long been used in urologic reconstruction but more recently applied to masculinizing gender affirmation surgery which has traditionally relied on autografting. The focus has been on restoring form and function to the donor site as well as facilitating treatment of urethral stricture and wound complications after phalloplasty. Furthermore, aesthetic applications have also been described, most recently for glans atrophy.
SUMMARY: The field of masculinizing gender affirmation surgery represents an exciting frontier for surgeons and patients alike. Given the relative nascency of the specialty and its propensity to draw techniques from various surgical disciplines there exists a unique opportunity for rapid innovation to overcome challenging problems posed by these complex procedures as evidenced by discussions around applying penile transplantation and the use of novel tissue grafting techniques.
