There have been no previous studies evaluating whether previous genital surgeries, specifically orchiectomy and circumcision, affect skin availability during gender-affirming surgeries. METHODS: Intraoperative measurements were taken from 268 patients who underwent vaginoplasty at our institution from May 2016 to January 2021. These included measurements of penile skin, scrotal skin graft surface area available, and perineal length. We also collected demographic variables of age and BMI, and completion of orchiectomy prior to vaginoplasty. Mean skin measurements were compared between orchiectomy status using a two-sample t-test. A multivariate linear regression model was completed with scrotal skin availability as the outcome and prior orchiectomy as the predictor while controlling for age and BMI. RESULTS: Patients ranged in age from 15 to 73 years. Fifty-six (23%) patients had prior orchiectomy. Those who had prior orchiectomy had less total scrotal skin available for grafting (114 cm2 versus 140 cm2; p=0.001). When considering factors such as body mass index (BMI) and age, higher BMI was statistically associated with more total scrotal skin availability (p=0.02), but age was not (p = 0.2). In the multivariate model controlling for age and BMI, patients who had undergone prior orchiectomy were still estimated to have less scrotal skin availability than those without prior orchiectomy (p<0.001). CONCLUSIONS: Prior orchiectomy, regardless of potential confounders such as age and BMI, was associated with less scrotal skin available for graft use. This information may guide surgical counseling and operative planning for gender-affirming vaginoplasty.
