Vascular composite allografts are at the forefront of medical and surgical innovation. With this new technique and the ability to transplant a face, hands, an abdominal wall, a uterus, or even a penis, patients can undergo operations that may drastically improve their quality of life. Although this process presents significant opportunities it is not always an easy road and requires significant upfront counseling and life-long immunosuppression. Often the recovery course is long, with functionality taking months to years to gain. Immunosuppression must be used to prevent rejection of the allograft although it has serious long-term side-effects. Only five patients have undergone penile allotransplantation but reported outcomes from these small numbers have nonetheless offered significant lessons with each patient. While the operation is still in its infancy, it is certain that shared experiences by surgical teams will yield improved outcomes in the future.
