Cervical tissue biopsies from fifteen pregnant women who were seeking a second trimester elective abortion were examined before and after sulprostone systemic administration, to evaluate the hystological and ultrastructural modifications. While light microscopy showed an increase in vascularity and a submucosal edema with an infiltration of inflammatory cells, electron microscopy pointed out a complete dissociation of collagen fibers with a large increase of basic substance constituents. These features are similar to modifications found in the ripening process at term, demonstrating that sulprostone can be useful to prime uterine cervix.
