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.
Sterilization is a permanent method of birth control. Sterilization procedures for women are called tubal occlusion. The procedure for men is called vasectomy. Tubal occlusion closes off the fallopian tubes. This prevents the egg from moving down the fallopian tube to the uterus and keeps the sperm from reaching the egg. Sterilization is a highly effective way to prevent pregnancy. Fewer than 1 out of 100 women will become pregnant within 1 year of having the procedure. After 10 years, pregnancy rates range from fewer than 1 to fewer than 4 out of 100 women, depending on the type of sterilization method used.
