Long Term Fate of Testis Prosthesis after Metoidioplasty and Phalloplasty.

Abstract

To identify specific complications associated with testicle prosthesis at our dedicated transgender surgery center, over a long follow up period exceeding 5 years. We conducted a retrospective chart review of all transmasculine patients undergoing testicular implants after metoidioplasty or phalloplasty between January 2016 to November 2019, stopping the series in 2019 to allow at least 3 year follow up. 23 patients were identified, 16 (70%) of whom had a prior metoidioplasty and 7 (30%) with prior phalloplasty receiving only testicular implants (no penile implant). The average follow up period was 5.25 years (range 3.11-7.06 years). Four (17%) patients experienced a scrotal wound, either minor epidermal loss or a small eschar, on the scrotum that required no intervention. Zero patients experienced scrotal wounds requiring surgical or bedside debridement. Zero patients experienced prosthesis infection, extrusion, or implant leakage. One patient (0.04%) had their implant replaced due to malpositioning and went on to have a second implant placed without complications. The outcomes of testicle implants in our cohort compare very favorably to published reports over an extensive follow up period.
