Seasonal changes of the testicular interstitial tissue were studied by electron microscopy. During the breeding season in spring, clusters of Leydig cells are surrounded by wide lymphatic sinusoids. In sexually quiescent moles, these sinusoids collapse, and the abundant Leydig cells become closely packed and occupy most of the testis. During sexual activity, the Leydig cells contain abundant smooth endoplasmic reticulum (SER), mitochondria with tubular cristae, and lipid droplets. Some areas of the cytoplasm are occupied exclusively by tubular SER, arranged in parallel. During regression the SER appears tortuous, and large lipid droplets are found in the cytoplasm, although these gradually become smaller. During the long period of sexual quiescence, the size and abundance of Leydig cells and the appearance of SER, lipid droplets and mitochondria were similar to those observed during sexual activity.
通过电子显微镜研究了睾丸间质组织的季节性变化。在春季繁殖季节，成群的睾丸间质细胞被宽阔的淋巴窦包围。在性静止期的鼹鼠中，这些窦塌陷，大量的睾丸间质细胞紧密堆积，占据了大部分睾丸。在性活动期间，睾丸间质细胞含有丰富的滑面内质网（SER）、具有管状嵴的线粒体和脂滴。细胞质的一些区域完全被平行排列的管状SER占据。在退化过程中，SER变得扭曲，细胞质中发现大的脂滴，尽管这些脂滴逐渐变小。在性静止的长期阶段，睾丸间质细胞的大小和数量以及SER、脂滴和线粒体的外观与性活动期间观察到的相似。
