Yes, pregnancy is possible after sterilization, but it is very rare.
What is sterilization?
Sterilization is a permanent method of contraception. In women, it usually involves tubal ligation—cutting, tying, or blocking the fallopian tubes to prevent eggs from reaching the uterus.
How can pregnancy happen after sterilization?
- Recanalization: The fallopian tubes may naturally rejoin or form a new path, allowing fertilization.
- Failed procedure: Tubes were not completely blocked or sealed during surgery.
- Pregnancy before the procedure: If a woman was already pregnant but unaware.
- Time factor: The longer the time since sterilization, the higher (though still low) the chance of failure.
Risk of Pregnancy After Tubal Ligation:
- About 1 in 200 women (0.5%) may become pregnant after tubal ligation over a 10-year period.
- Risk is slightly higher if the procedure was done at a younger age.
Important Note:
Pregnancy after sterilization has a higher risk of being ectopic (outside the uterus, usually in the tube), which is a medical emergency.
