Scrotal construction by expansion of labia majora in biological female transsexuals.

Construction of male genitalia in biological female transsexual patients is problematic. We report 3 transsexuals with scrotal construction by tissue expansion of the labia majora. In each patient, tissue expanders were inserted into the labia majora several months before free flap phalloplasty. In 2 patients, the tissue expanders were removed, and testicular implants were placed into the labial pockets. In the other patient, the tissue expanders were left in place. Because of the close embryological relationship between the labia majora and the scrotum, the neoscrotum appears natural in color match, hair pattern, and skin texture. The anatomical position of the labia majora produces a scrotum properly located in relation to surrounding anatomical structures. Excellent aesthetic results can be achieved with this procedure. Based on our experience, we advocate this procedure for scrotal construction in biological female transsexual patients.
