Histopathological effects of silicone rubber 'Ovabloc' on the human fallopian tube.

OBJECTIVE: To study the histopathological effects of silicone rubber on the human fallopian tube. METHODS: A prospective longitudinal study at Benha University Hospital and Boulak Eldakrour General Hospital, Egypt. Nine patients who were on the waiting list for hysterectomy and requested postponing of their operation for personal reasons. RESULTS: Our results suggest that silicone rubber induces histopathological changes in the form of ciliary loss and intracellular changes. CONCLUSIONS: These effects tend to increase with the increase of the duration of tubal plugging and are best seen by electron microscopy.
