p<0.001) [Table 1]. The median change in GW preoperatively to surgery was 4mm for those receiving T vs -1mm for those not receiving T (p<0.001). We observed a trend toward significance of increased administration of T for firstand second-stage repairs (p[0.062) and concordantly a higher proportion of proximal hypospadias patients received T (p[0.003). We identified a greater change in GW from preoperative to intraoperative measurements in patients who received two doses of T vs one dose (4mm vs 2mm, p<0.001) [Table 2]. A histogram plot revealed the distribution of GW change at surgery (Figure 1). CONCLUSIONS: In our large, prospectively collected cohort of patients undergoing hypospadias surgery, we were able to quantitate the change in GW from preoperative testosterone. Two doses of testosterone resulted in a significant increase in glans width vs one dose.
