Tubal ligation and unexpected pregnancies
Tubal ligation is considered one of the most effective methods of birth control because the risk of pregnancy afterward is very low. Roughly one in 1,000 women will experience a pregnancy within the first year after the surgery, and 2-10 women in 1,000 will potentially get pregnant within 5 years of the procedure. However, an unexpected pregnancy after tubal ligation could be ectopic, which can be life-threatening.
Trying to conceive after tubal ligation
Because tubal ligation is reversible, a woman can still potentially conceive after having the surgery. More than 14% of women who have had tubal ligation later ask for information about reversing the procedure. Women considering a reversal procedure should know that the success rates for reversing tubal ligation vary widely from 25-80%. Likewise, women who undergo reversal may have a higher risk of ectopic pregnancies. Factors that can impact conception rates after tubal ligation reversal include:
- Health and length of fallopian tubes
- Type of surgery that was used
- Quantity of scar tissue
Age and fertility go hand in hand
Just like with women who haven’t had tubal ligation performed, age plays a major factor in whether or not a woman can successfully conceive after a reversal procedure. Women over 40 are usually discouraged from reversing tubal ligation because the success rates for conceiving naturally afterward can be very low. Experts usually recommend that women who are 35 or younger are better candidates for tubal ligation reversal procedures as the pregnancy success rate is between 70-80%.
Tubal ligation and in-vitro fertilization
Whereas women under 35 have higher pregnancy success rates after a reversal procedure, women over 40 see a success rate of 30-40%. If a woman isn’t considered a candidate for tubal ligation reversal, other fertility options can be considered. One of the most popular methods is in vitro fertilization (IVF). With IVF, a fertility specialist will place a woman’s fertilized eggs directly into the uterus. IVF allows for a woman or couple to successfully conceive while bypassing the need for the fallopian tubes entirely.
What to know about reversal
Although tubal ligation can be reversed, the type of surgery for the initial procedure and the amount of scar tissue created can also impact future fertility rates. Experts recommend that women who may have a desire to reverse the surgery should request for a ring/clip sterilization over methods that may create more scar tissue. Another factor to consider is the quality of a partner or a donor’s sperm. Tubal ligation, while an effective birth control method, isn’t a finality for fertility. Women who are interested in conceiving after having the procedure should speak to a fertility specialist to get a better understanding of options and to create a strategy.
