Two types of fibrous structures can be demonstrated in midcycle cervical mucus: (1) long, thick fibers that vary in diameter from 0.5 to 5 mum and run parallel to each other, and (2) microfibrils that vary in diameter from 500 to 1,500 A and form bundles or networks. The spaces in such networks usually measure from 800 to 4,0000 A. The fibers are made up of the microfibrils and most likely represent the micelles that give spermatozoa their directional transport through the cervix.
（1）长而粗的纤维，直径在0.5至5微米之间，相互平行排列；（2）微纤维，直径在500至1500埃之间，形成束状或网状。这种网络中的间隙通常为800至40000埃。纤维由微纤维组成，很可能代表了使精子通过宫颈进行定向运输的微胶粒。
