睾丸引带的解剖及组织学研究

A Research on the Anatomy and Histology of Gubernaculum Testis

目的:了解睾丸引带的组织学特性和解剖学特征,探索睾丸引带在睾丸下降过程中的作用。方法:解剖14具不同胎龄死胎,记录睾丸位置、引带形态及末端附着部位并切取引带作组织学检查。结果:睾丸引带为横纹肌,末端附着于耻骨联合和腹股沟韧带并且随睾丸下降逐渐缩短变细。结沦:人类睾丸引带在睾丸下降过程中可能起引导和牵引睾丸通过腹股沟管的作用,但不能牵入阴囊,睾丸引带缺如或提前退化可能是隐睾的重要因素。

Objcetive:To understand the histological and anatomic characteristics of the gu- bernaculum testis,and to research the role of the gubernaculum in the process of testicular de- scent.Methods:The testicular position,morphology,histology and location of gubernaculum testis of 14 dead fetuses with different gestational age were studied.Results:Gubernaculum testis consisted of striated muscle with the lower extremity attaching to the symphysis pubis and inguinal ligament.It shortens and attenuated gradually as the testicle descends.Conclusions:The human gubernaculum testis may play the role of leading and drawing testicle down through the inguinal canal in the process of testicular descending,but it can't draw the testicle into the scrotum.The absence and the premature regression of gubernaculum testes may be important factors causing un- desended testicles.
