Procedures for testicular prosthesis implantation in transgender men have changed over time, scientists report in the Journal of Sexual Medicine.
During gender affirmation surgery, transgender men generally undergo phalloplasty (surgical creation of a penis using tissue from elsewhere in the body) or metoidioplasty (creation of a penis from the clitoris, which enlarges during previous testosterone therapy).
A neoscrotum can be developed with fat tissue, but testicular prostheses are a closer match in shape and size to natural testicles. However, the long-term outcomes of testicular prosthesis surgery are not thoroughly addressed in the medical literature.
