The microvascularization of the layers of the tunica vaginalis propria testis in juveniles and youths is different in morphological parameters which is responsible for their participation in metabolic processes. The distribution of vessel diameters is based on the regularity of random variation. The number of classes for each link of the microcirculatory bed in the tunics studied practically coincide. In any microvascular part of the parietal and visceral layers of the vaginal tunic of the testis a class (a leading functional group of vessels) may be established which has substantially greater density than that of other classes of the variation line presented. The results of morphometry show the prevalence of the venular portion over the arterial one in each of the layers under study. However, the difference between the venular and arterial portions of the microcirculatory bed is more considerable in the parietal layer which is sure to influence the degree of its outflow from the microvascular system.
青少年睾丸固有鞘膜各层的微血管化在形态学参数上存在差异，这导致它们参与代谢过程的情况有所不同。血管直径的分布基于随机变化的规律。在所研究的鞘膜中，微循环床各环节的类别数量实际上是一致的。在睾丸鞘膜壁层和脏层的任何微血管部分，都可以确定一个类别（血管的主要功能组），其密度明显高于所呈现的变异线的其他类别。形态计量学结果表明，在所研究的各层中，静脉部分比动脉部分更为普遍。然而，微循环床的静脉部分和动脉部分之间的差异在壁层更为显著，这肯定会影响其从微血管系统的流出程度。
