The morphological aspects of the cervix uteri of twelve albino rats, six in estrus and six in diestrus were studied. Micrometry of the epithelium thickness was performed and it was observed that the epithelium is significantly thicker during the estrus phase of the cycle than in diestrus. The major causes for this are discussed and the findings are correlated with the estrogen and progesterone levels present in each of the mentioned phases.
