目的：探讨一种可复性节育的新方法。方法：选择生育一次以上的雌兔，施行手术置管，术后雌雄兔合笼饲养，观察期３个月。３个月后未受孕者行取管术，取管后雌雄兔继续合笼饲养，再次生育作为研究终点。结果：置管成功率为１００％，雌兔置管后均未见生育。取管后再生育即复孕率为５０％（２／４）。结论：输卵管置管可复性节育术方法新颖，不易脱落，安全可靠，可复性好，复孕率高。 Objective: To explore a new method of refolding and birth control. Methods: Female rabbits more than one time were selected for operation and catheterization. The male and female rabbits were kept in cage for 3 months. After 3 months, the uninfected people were taken out of the tube, and the male and female rabbits were kept in cage again after taking the tube, and the second birth as the research end point. Results: The successful rate of catheterization was 100%. No female was born after birth. Re-birth after take control that the rate of pregnancy was 50% (2/4). Conclusion: Tubal tube retrograde method of birth control is novel, not easy to fall off, safe, reliable, reproducible, and high rate of pregnancy.
