Accordingly, it remains imperative to better understand the factors that contribute to patient noncompliance. Prior studies on PVSA noncompliance do not explore how geographical barriers in returning samples impact completion,3 despite perceived inconvenience being cited by men as a barrier to completion.4 We performed a review of a contemporary, institutional cohort of patients that underwent vasectomy to investigate sociodemographic and clinical factors associated with failure to complete …
