Abstract

Vasectomy is the most popular method of birth control in Korea. Because of changing views about family life, increasing prevalence of divorce and remarriage, desire for more children, and fear of child death. a large number of men now. are requesting reversal or vasectomy. Between March 1987 and September 1991 we performed vasovasostomy using modified one-layer technique with optical loupe magnification in 58 patients who had underwent vasectomy for family planning. Of these 58 patients, 46 patients could be followed up. Rates of patency and pregnancy varied depending on the interval from vasectomy until its reversal. Patients whose vasectomies had been performed less than 5 years had a 95.0% patency rate and a pregnancy rate of 72.0%. Patients who had an obstructive interval of 5 to 10 years had a 85.7% patency rate and a pregnancy rate of 50.0%. Beyond 10 years, there was a 33.3% patency rate and a pregnancy rate of 0.0%. The overall success rate was 86.5% for patency and 58.7% for pregnancy. Since the modified one-layer vasovasostomy is easier, faster, and less expensive, this technique deserves further clinical experience and evaluation.
