Phalloplasty is often the final stage of gender-affirmation surgery for transgender men. Obtaining penile rigidity is important for sexual function, but may also bring complications, including supersonic transporter deformity, in which the glans becomes ventrally displaced and flaccid. Two cases of supersonic transporter deformity are presented here, one with a hydraulic penile implant and one with an autologous bone transplant. Attempt at surgical correction was performed in both. Careful attention must be paid to the unique anatomy of the neophallus and type of penile prosthesis to prevent or correct supersonic transporter deformity in transgender men.
