PREDICTORS OF SUCCESS OF REVERSAL OF STERILIZATION

Objective: To determine the prognostic variables effecting the success ful pregnancy outcome of reversal of sterilization. Design: Demographi c and clinical history data were collected prospectively. Setting Divi sion of Infertility and Reproductive Endocrinology, Department of Obst etrics and Gynecology, University of British Columbia, Vancouver, Cana da. Patients and Intervention: Between 1981 and 1992, 217 consecutivel y referred patients underwent reversal of sterilization by a single su rgeon using microsurgical techniques. Main Outcome Measures: Prognosti c variables associated with success were examined using logistic regre ssion and expressed as odds ratios with corresponding 95% confidence i ntervals. Results: Age at reversal was a significant factor with the o dds of a successful outcome for those less than or equal to 35 years c ompared with those >35 years being 2.3 with a 95% confidence interval of 1.3 to 4.1. There was some evidence that average tubal length as ca tegorized in 2-cm intervals was a significant prognostic factor with t he odds of a successful outcome for those with an average length of >4 cm to those less than or equal to 4 cm being 5.3 with a 95% confidenc e interval of 1.4 to 20.0. Conclusions: Nonsubjective analysis of the prognostic variables of reversal of sterilization associates only age and tubal length of >4 cm with intrauterine pregnancy.
