Scanner electron microscopy of the cervical mucus

Abstract

The cyclical changes that appear in the fibrillar structure of the cervical mucus are described using scanner electron microscopy (SEM). During ovulation the fibrillar mesh is formed of microfibers of 500 to 5000 A that form a large open network, that is not very dense noted by ample spaces (up to 40 mu) between the fibers. During the rest of the cycle the mesh is very dense and the fibers are very thick and less elastic.
