隐睾发生的危险因素研究现状

The current study status of risk factors for cryptorchidism

睾丸是雄性生殖系统的核心器官，睾丸下降不全（隐睾）不仅影响出生后睾丸的发育与功能，还间接影响其他泌尿生殖系统的结构和功能可至成年。大量流行病学研究发现隐睾发生率呈明显增高趋势，其病因及相关危险因素虽一直备受关注和研究，但尚无定论。研究隐睾发生的危险因素，对其有效防治具有重要意义。现就遗传和环境因素两方面对隐睾发生的可能危险因素进行概述。

Testis is the core organ of the male urogenital system. The undeseended testes （eryptorchidism） not only affect on the development and function of testis after birth, but also affect the other organs in male urogenital system until adult. More and more epidemiologic studies reveal that the incident of eryptorehidism has increased. Although the etiology and related risk factors have been focused, the mechanism of eryptorehidism is still unclear. To learn more about the risk factors is significant to prevent this congenital disease. The current research data about the genetics and envi- ronmental factors of eryptorchidism is reviewed in this paper.
