title: Overall satisfaction, sexual function, and the durability of neophallus dimensions following staged female to male genital gender confirming surgery: the Institute of Urology, London U.K. experience.
abstract: OBJECTIVE
  What factors influence transgender men's decisions to undergo (and to not undergo) specific genital gender confirming surgeries (GCS) has not been described in the literature. Sexual function outcomes related to clitoral transposition and penile prosthesis placement is also not well described. Durability of neophallus dimensions after phalloplasty has not been described. A better understanding of these factors is necessary for pre-op counseling. We sought to assess patient genital-GCS related satisfaction, regret, pre/post-op sexual function, genital preferences, and genital measurements post-op.
  
  
  METHODS
  We evaluated ten female to male transgender patients who had previously undergone suprapubic pedicle-flap phalloplasty [suprapubic phalloplasty (SP); N=10] and 15 who had undergone radial artery forearm-flap phalloplasty [(RAP); N=15; 5/15 without and 10/15 with cutaneous nerve to clitoral nerve anastomosis] at our center (UK). We queried patients' surgery related preferences and concerns, satisfaction, and sexual function pre/post-surgery, and accounted for whether patients had undergone clitoral transposition and/or cutaneous-to-clitoral nerve anastomosis. We measured flaccid and (where applicable) erect length and girth using a smart-phone app we designed.
  
  
  RESULTS
  Mean age at surgery and follow-up for those that underwent SP was 35.1 and 2.23 years, and 34 and 6.8 for those that underwent RAP. Mean satisfaction scores were 9.1/10 and 9/10 for those that underwent SP and RAP, respectively. No patient (0%) regretted starting genital-GCS surgery. All (100%) patients that could achieve orgasm before GCS with clitoral transposition could achieve orgasm after surgery, and the vast majority reported preserved quality of erogenous sensation by our transposition technique. All (100%) RAP and 9/10 SP patients reported masturbation with their phallus. Inflatable penile prosthesis placement was not associated with decreased erogenous sensation/orgasm. Penile dimensions were relatively stable through follow-up for both groups. Our App length measurements correlated with a ruler within ±<4.5%.
  
  
  CONCLUSIONS
  Female-to-male genital-GCS offered in 3-stages was associated with high overall satisfaction and no regret among our sample. Sexual function appears to be preserved after both clitoral transposition and inflatable prosthesis placement, and consolidation of erogenous sensation to the phallus was described as important to all subjects. Discussion of patient's pre-op sexual function, as well as specific concerns and preferences related to specific genital-GCS surgeries is important.
