Hormonal bases of the correspondence between microscopic and ultramicroscopic features of human cervical mucus.
By studying the changes of microscopic and ultramicroscopic structure of cervical mucus and the corresponding changes of ovarian hormone levels throughout the cycle, a close correspondence was found between micro and ultramicrostructures. The optical structure of non canalized mucus and the electronic features of membranous mucus maintained a similarly unvaried morphology in spite of the striking changes in hormonal levels during the cycle. On the contrary, a varied morphology corresponding to the changes of cyclic levels of ovarian hormones was observed in the optical structure of canalized mucus and in the electronic features of filamentous mucus. Therefore, whatever its micro or ultramicroscopic features, the dehydrated mucus showed two components, one dependent and the other independent of ovarian hormones. A similar conclusion has also been reached for fresh mucus components.
