INTRODUCTION AND OBJECTIVE: Testosterone (T) use prior to hypospadias surgery remains controversial. Understanding its effects on glans size is essential to understanding its efficacy. Our hypothesis was that T preoperatively increases GW measured at surgery. Our goal was to quantify the change with and without T prior to surgery. METHODS: Our database was queried to identify patients who underwent hypospadias surgery from 2015-2019, in which data for T administration and glans measurements were available. Descriptive, nonparametric and categorical statistics were performed as indicated.RESULTS: 648 patients were eligible for analysis. Median age at surgery was 0.9 years (IQR 0.6-1.7). 200/648 (31.3%) patients received T. The median GW at surgery was 15mm (IQR 13-17). When comparing patients who had T administered to those that did not, we e972
