...Annetrudi Kress; Christian Regli; Udo M. Spornitz; Gianni Morson The four stages of the estrous cycle in Monodelphis domestica , namely proestrus, estrus, postestrus and the transitional metestrus, were analyzed with the scanning electron microscope and compared with the results of the previously...

...S. van Cruchten; W. van den Broeck; F. Roels; P. Simoens The endometrial surface morphology of 38 dogs during different stages of the estrous cycle was investigated with scanning electron microscopy. The cell surface altered from convex in proestrus and estrus to very variable in early metestrus...

... the estrous cycle the vaginal epithelium undergoes a number of specified morphological changes. This paper is the first to describe these changes on an ultrastructural level in a marsupial. Investigations in Monodelphis vagina reveal that a cyclic switch exists between a keratinized and a stratified...

...Regula Wick; Annetrudi Kress Ultrastructural changes in the cervical epithelium related to the estrous cycle have been studied in the South American marsupial Monodelphis domestica . The two cervices protrude with prominent papillae into the sinus vaginalis. At times of simple columnar at others...
