Genes associated with hypospadias: an update / 中华男科学杂志

ABSTRACT

Hypospadias is one of the most common congenital malformations, and its main clinical manifestation is the abnormal opening of the urethra. Etiologically, it can be attributed to many factors, mainly including genetic, hormonal, and environmental factors. Recently studies about its genetic etiologies have found a variety of hypospadias-associated genes from the aspects of epidemiology and polymorphism, mainly those involving the formation of the penis, the development of the testis, the anabolism of androgens, and so on. This review focuses on the progress in the studies on the genetic etiology of hypospadias.
