Abstract

The aim of this study was to determine the prognostic factors and pregnancy rates after microsurgical reversal of tubal sterilization. Patients undergoing tubal anastomosis from 2001 to 2008 were included. Relevant data were extracted from their medical records. Pregnancy outcomes were ascertained by responses to mailed questionnaires and telephone contact. A total of 98 patients were identified. We found that the mean duration of follow-up was 67 ± 28 months. Fifty-five patients conceived (pregnancy rate 62.5%; 95% confidence interval [CI] 52 to 72.8%). Of these, 50 were intrauterine and 5 were tubal pregnancies. Life-table analysis estimated cumulative pregnancy rates to be 30.7%, 39.8%, 49%, and 53.7% at 6, 12, 18, and 24 months after reversal, respectively. Age at the time of reversal was the only significant prognostic factor multivariate model. We concluded that age of the patient at the operation is the most important prognostic factor.
