Pregnancy After Endometrial Ablation: Study Review

After ablation pregnancy can happenPregnancy after endometrial ablation does occur. Estimates are approximately 0.7% of patients who have an endometrial ablation will accidentally become pregnant.

Some patients who have an ablation will desire pregnancy after their procedures. Many will have had a tubal ligation and will ask us about the possibility of tubal ligation reversal and the risks of pregnancy after endometrial ablation.

The tubal reversal doctors of Chapel Hill Tubal Reversal Center have dedicated this series of articles to these women seeking more information about pregnancy possibilities after ablation. This is the third article in our series on endometrial ablation, tubal reversal, and pregnancy. This article will present information from the two largest medical studies of pregnancy outcomes after endometrial ablation.

Readers are advised to read the preceding articles in this series:

Tubal Ligation Reversal and Ablation

Our specialty center is dedicated to corrective tubal surgery and tubal ligation reversal. As of 2009 we have performed over 8,000 reverse tubal ligations.

Tubal specialty where ablation patients can untie tubesWe maintain a pregnancy database and the success rates of pregnancy after tubal reversal can be as high as 90%.

Our patients come from across the United States and from other countries throughout the world. Many of these women will have unique types of tubal ligations, for example, the Uchida tubal ligation,  Irving and Parkland tube tying procedures, and the Essure and Adiana tubal blockage procedures.

A few of our patients will have had endometrial ablations and will come to have tubal ligation reversal.

Pregnancy After Ablation: United Kingdom

A UK research team recently reviewed the outcomes of 70 pregnancies after endometrial ablation. In this study, 31 of the 71 pregnancies identified were live born. Of these 31 live born pregnancies, 4 infants died and 31% were born before 37 weeks. One out of four patients had very adherent placentas.

This review illustrates that pregnancy after endometrial ablation is possible, but is not without risks and complications. Although it is difficult to generalize, this study suggest about 50% of all pregnancies after endometrial ablation will make it to fetal viability (>24 weeks) and of these approximately 1 out of 3 will be born before term (37 weeks). Some infants will die as a result of premature birth and some women will have very adherent placentas.

Pregnancy After Uterine Ablation: Australia

An Australian group of researchers published a review on pregnancy after uterine ablation in 2003. This group was able to identify 43 pregnancies  after uterine ablation. Of these pregnancies after uterine ablation, 17 progressed beyond 20 weeks gestation. One of the successful pregnancies was a planned pregnancy, which occurred after endometrial ablation and a tubal ligation reversal.

Tubal Reversal And Endometrial Ablation: Is Pregnancy Possible?

A tubal ligation reversal and natural pregnancy after an endometrial ablation is possible. Many women will need to be aware of the risks and complications of these pregnancies.

Pregnancy after ablation is considered high riskSince endometrial ablation was first introduced as a treatment to decrease heavy menstrual periods, medical researchers discovered and reported on some serious complications associated with pregnancy subsequent to endometrial ablation: premature birth, fetal death, abnormal placental attachment resulting in emergency hysterectomy, and some maternal deaths.

As endometrial ablation has become widely performed, the medical literature has become more balanced and has also revealed some pregnancy success stories. Overall, the risks and complications for women in pregnancy are increased after an endometrial ablation; however, the medical community still has a poor understanding of the effects of endometrial ablation upon pregnancy.

Pregnancy After Reversal And Uterine Ablation: Our Advice

The next article in our series is Endometrial Ablation and Tubal Ligation Reversal: Advice. We will offer advice on pregnancy and tubal reversal after uterine ablation.  We will provide some suggestions on who may be a candidate for tubal reversal and what steps can be taken to optimize the chance for pregnancy success after an endometrial ablation procedure.

    I had a ablation done in 2010, I thought it was a good decision at that time in my life, but now have decided to have another child. I am not sure if I can,I have to see the OB/GYN in Aug. I am hoping I can have another child at my age now 44…. thank you for this site and all the positive feed back from others who have gone through the ablation, and for the medical staff for your answers to our questions…. I have my fingers crossed to a positive outcome for me too!

    Hi my name is heather and I got an ablation 2 yrs in January 2010. I met the man of my dreams and we want to conceive. I am having light regular flow and I do have some regrowth in the uterus but at this point not enough. Does anyone no if scar removal increases chances of pregnancy if also taken with estrogen? I am desperate to carry and to love my husbands baby. Please any info would help thanks

    Its great to see more information for women who find themselves pregnant after ablation. Very little promising info was available when we found ourselves in this situation in 2009. Our son was born at 34 weeks, 4 lbs. 1.5 oz. Our OB/GYN was wonderful! Many suggest termination, though, so it is great to see a site with info that gives caution and hope at the same time. Best wishes.
