[Reversal operation after female sterilization by mucilago phenol]

A reversal operation after occlusion of fallopian tubes by mucilago phenol was carried out in 30 women. A revised method of tubocornual implantation was the operation of choice. The resected portions of the tubes were examined by both light microscope and electron-microscope and no abnormalities were observed in the portion of the tube adjacent to the occluded segment. After reversal, the tubal patency rate was 97%. During a follow-up period of 18-26 months, the pregnancy rate and term-pregnancy rate was 76% and 72% respectively. The results indicate that occlusion by mucilago phenol is a reversible method of tubal sterilization.
