隐睾症有着变成睾丸瘤的较高发病率,如同包茎发生阴茎癌一样;因此在预防方面,睾丸固定术亦好像包皮环切术一样重要,并且还能防止其它并发症。隐睾症是指:凡睾丸不在阴囊内正常部位的总称。在胚胎期睾丸形成时在腹膜后腔位置极高,以后随着发育逐渐下降,穿过体壁诸层,经腹股沟管而移向阴囊。胚胎期睾丸下降的因素:(1)胚胎发育期躯干伸长迅速,因此生殖腺的位置相形后移。(2)当胚胎第七个月时,睾丸之引索(Guber Na-culum of Tesitis)缩短,睾丸受引索的牵引拉向阴囊。
Cryptorchidism has the high incidence of becoming testicular tumors, just as penile cancer occurs in phimosis; therefore, testicular fixation is as important as circumcision in prevention and can prevent other complications. Cryptorchidism refers to: Where the testicles are not normal parts of the scrotum in general. In the formation of embryonic testes in the retroperitoneal position is extremely high, then gradually decline with the development, through the body wall layers, the inguinal canal and the scrotum. Fetal decidual testicular factors: (1) rapid extension of the embryo during embryonic development, so the gonadal position of the relative shift. (2) Guber Na-culum of Tesitis was shortened at the seventh month of embryo, and the testis was pulled by traction on the scrotum.
