The authors used a scanning electron microscope to study epithelial damage to the rabbit fallopian tube after sterilization with different methods and its subsequent capacity to regenerate after recanalization. Thirty female NZW rabbits were divided into five groups and sterilized using the following methods: (1) Madlener (2) Pommeroy, (3) clips, (4) unipolar coagulation, (5) bipolar coagulation. Each group was divided into subgroups of two and submitted at differing intervals to a second laparotomy, during which one tube was removed and the other anastomosed according to Winston's method. Four weeks after the second laparotomy all the rabbits were sacrificed, the remaining tube removed, and all tubes examined with the scanning electron microscope. The results indicate that mechanical methods of occlusion such as clips offer greater recovery possibilities than those in which the lesion is extended to the mesosalpinx. There further exists a correlation between the time that elapses after sterilization and regeneration of the epithelium.
