Hypospadias prevalence in the Emilia Romagna Region registry: Increasing or methodology?

Introduction: Hypospadias is one of the most common congenital anomalies in male infants, defined as incomplete development of the urethra. Despite the wealth of literature, there are conflicting data on the values and trends of prevalence, due to multifactorial origin but often also to methodological differences between studies. The aim of this study was to analyse prevalence, trends and risk factors of hypospadias in the Emilia Romagna Region, Italy.
