In order to study the mechanism of chemical occlusion of fallopian tubes as a procedure of sterilization, Bai Dian Fen (a mixture of rhizoma bletillae iodine and phenolic compound was injected) into the fallopian tubes of rabbits. 70 rabbits were divided into 8 groups and exposed to different observation times 24 hours to 24 weeks from the time of injection. Pathological changes in the fallopian tubes were observed microscopically. First, cell inflammation and expansion of veins was observed after the injection. Three days later, excretion appeared inside the wall of the fallopian tubes. Two weeks later, the quantity of inflammatory cells reduced, and a overgrowth of granulation started to gloss the lumen of the fallopian tubes. Between 6 and 10 weeks, fibroplasia and fibrosis was formed, and the fallopian tubes were totally blocked. Occlusion of the fallopian tubes was successful in all the rabbits except one.
