Abstract
Between 1979 and 1985, 25 consecutive, unselected women (age 28–40 years, median 34) underwent microsurgical tubo-tuba1 anastomosis for reversal of sterilization. The overall pregnancy rate was 44%. The incidence of pregnancy was correlated to the tubal length after reversal. Of 12 women with tubal lengths exceeding 5.5 cm, 8 (67%) became pregnant. Of the 13 women with tubal lengths under 5.5 cm only 3 (23%) conceived (p >0.04). There was no significant correlation between pregnancy rate and age, interval since sterilization, or the sterilization procedure itself.
