Abstract
The pregnancy rate of 63 women who underwent macrosurgical reversal of sterilization is reported. The pregnancy rate is based on life table estimates. The present material is the largest reported with this method. No statistically significant correlation was found between pregnancy outcome and tube length, anastornotic site, technique of sterilization, day of refertilization in menstrual cycle, or time interval between sterilization and refertilization. Using life tables, the cumulative probability of intra-uterine pregnancy 6, 12, 24, 36, 48 and 66 months after surgery was 14%. 26%, 39%. 39%, 43%, and 51% respectively. Our results of macroscopic sterilization reversal are comparable to the reported results of microsurgical methods. They support the contention that atraumatic technique rather than the microscope is important for good results.
