Serial sections of vaginal plugs of mice, rats, guinea pigs and hamsters (Cricetulus griseus) were studied by light microscopy as well as whole plugs and freeze-fractures by scanning electron microscopy. The vaginal plugs are encircled by a layer of superficial cells of the vaginal epithelium and consist of coagulated seminal fluid, containing irregular holes. The spermatoza are mainly localized inside bigger cavities. Scanning electron microscopic study of freeze-fractured plugs reveals, that this method gives useful information about the inner structure of spermatozoa tails.
对小鼠、大鼠、豚鼠和仓鼠（黑线仓鼠）阴道栓的连续切片进行了光学显微镜研究，同时对整个阴道栓和冷冻断裂样本进行了扫描电子显微镜研究。阴道栓被一层阴道上皮的表层细胞包围，由含有不规则孔洞的凝固精液组成。精子主要位于较大的腔隙内。对冷冻断裂阴道栓的扫描电子显微镜研究表明，该方法能提供有关精子尾部内部结构的有用信息。
