Tubal biopsy specimens were obtained at the time of tubal reversal in 10 women who had had occlusive sterilization by phenol-mucilage; the interval between sterilization to reversal operation ranged from 1-7 years. Transmission electron microscopy revealed that at the site of the tubal occlusion there were abundant collagen fibrils, a few fibrocytes, and scattered lymphocytes. The mucosal epithelium adjacent to the tubal occlusion showed simple columnar ciliated cells and secretory cells. No pathological changes in these cells were seen. 5 of the 10 patients had become pregnant after 1 year following the reversal procedure. Author evidence suggests that the occlusive sterilization with phenol-mucilage does not induce any malignant changes in tubal tissues even after a long time. It is indicated that this method of sterilization is safe. However, bacteria were found in 1 mucosal epithelial specimen and attention should be paid to this observation. (author's modified)
