For women, the chances of getting pregnant after sterilization are similar to the chances for men. Having a tubal ligation or having your âtubes tiedâ closes the fallopian tubes, through cutting, burning, or blocking with clips, bands, or rings.n addition, it prevents sperm from reaching the fallopian tube. A tubal ligation is around 99.5% effective at preventing pregnancy. There are a couple of important factors to consider when thinking about surgical sterilization to reduce your chances of getting pregnant.
Mom Answers. Studies have shown that tubal ligation (tying of the fallopian tubes) is not a 100% guarantee of contraception. There's still at least a 1% chance of getting pregnant after your tubes are tied. This risk then increases to about 1.8% after 10 years. It has also been noted that most pregnancies occurring after ligation are ectopic in nature, meaning that the pregnancy occurs at the fallopian tube instead of the uterus.
