From 60 male corpse in the age of 13 to 77 both venae spermaticae internae were completely removed. On the basis of these specimens we investigated the incidence, localization, form and scale of the venous valves in the vena spermatica interna. All venous valves were remodeled and examined for their sufficiency on the basis of these date. In the left vena spermatica interna we found in 83% and in the right vena spermatica in 97% of the cases one or more valves. On the average the left vena spermatica contains 3.5 and the right 3.8 valves. From each vein a drawing was made, showing the remification, the localization of the valves and the valvular function. On the basis of this drawing and reconstructions of valves in the left vena spermatica interna for 90% of the cases and in the right vena spermatica for 75% of the cases a retrograde flow of the blood is possible. The absence of a varicocele can be explained by the presence of a sufficient venous valve on the left side in only 10% and on the right side in 25% of our cases. For the development of a varicocele therefore further facts are of importance.
从60具年龄在13岁至77岁之间的男性尸体上完整摘除双侧精索内静脉。基于这些标本，我们研究了精索内静脉中静脉瓣膜的发生率、位置、形态和大小。所有静脉瓣膜均进行重塑，并根据这些数据检查其功能是否正常。在左侧精索内静脉中，83%的病例发现有一个或多个瓣膜，右侧精索内静脉中这一比例为97%。左侧精索内静脉平均有3.5个瓣膜，右侧平均有3.8个瓣膜。从每条静脉绘制一幅图，显示其分支情况、瓣膜位置及瓣膜功能。根据这幅图以及对左侧精索内静脉90%的病例和右侧精索内静脉75%的病例进行的瓣膜重建，发现有血液逆流的可能。在我们的病例中，仅10%的左侧和25%的右侧存在足够的静脉瓣膜，这可以解释为何没有精索静脉曲张。因此，对于精索静脉曲张的形成，其他因素也很重要。
