In gerneral, at least 6 months interval is requird from operation to pregnancy, so among 35 patients, 8 of them whose follow-up interval were less 1han fj months from reversal of sterilization were excluded in the results of operation. The results were as follows: (1) Among 27 patietns, 8 of them conceived (30%).
