Post-tubal ligation pregnancy

03/02/2007

Question:

can a woman get pregnant after 9 years who has had a tubal ligation and still see a mentrual cycle?

Answer:

Tubal ligation is not 100% effective in preventing pregnancy and can fail over time. Depending on the age you had your tubal ligation performed and the method that was used the chance of failure ranks from 1 to 4% lifetime risk of pregnancy. The concern with post-tubal ligation pregnancies is that they have much higher chance of being an ectopic pregnancy than usual. The risk is somewhere between 40 and 50%. If you think you are pregnant and have had a tubal ligation it would be wise to check a home pregnancy test. If that is positive you should seek medical care immediately so it can be determined if the pregnancy is ectopic or not.
