Tubal Reversal Pregnancy Study
A Decade of Observation

Pregnancy Rates By Fallopian Tube Lengths

The tubal lengths that remain after a tubal ligation affect the chances of getting pregnant after tubal ligation reversal. (The fallopian tube length before a tubal ligation is about 10 cm or 4 inches.)

Tubal segment lengths were measured routinely during reversal surgery and recorded in operative reports during our surgeries. (Tubal length measurements were not part of the electronic database at the beginning of the study interval, so the numbers in the following table are less than the total number of patients during the entire period covered by the study.) The average length of the fallopian tubes after repair was correlated with the likelihood of pregnancy after tubal repair (Table 6).

Women with longer tubal lengths were more likely to get pregnant than women with shorter tubal lengths following tubal reversal surgery. 83% of women with tubal lengths of 7.5 cm or longer became pregnant. The probability of pregnancy declined as tubal length decreased, but even women with the shortest tubes (less than 2.5 cm) became pregnant. Although previously unreported in the medical literature, a repaired fallopian tube of any length can result in pregnancy. Based on reports by women with only 1 fallopian tube, we have discovered that tubal lengths as short as 1 cm can result in a normal pregnancy.

Length Total Women Pregnant (Number) Pregnant (Percent)
7.5+ 824 684 83%
5.0-7.4 4949 3621 73%
2.5-4.9 3114 1932 62%
<2.5 221 97 44%

Tubal Ligation Method And Tubal Length

When tubal ligation method and average tubal length are taken into account simultaneously, the amount of fallopian tube remaining after a sterilization procedure turns out to be the more important factor predicting the success of tubal reversal surgery. The less damage that occurs to the fallopian tube during a sterilization procedure, the more remains to be able to function normally once the tube has been surgically repaired. This explains the why women with tubal clips and rings – that cause the least amount of damage – are most likely to get pregnant after tubal reversal, as shown in the previous page of this report.

    Will the child born from a final reversal be affected any way? Just curious to see if children born after a reversal end up being “normal?”

    1. Dr. Monteith says:

      Tubal reversal allows you to become pregnant naturally. The only risk to tubal reversal is the increase risk of tubal (ectopic) pregnancy. There is no increase risk of birth defects because your tubes have been rejoined.

  2. Vanessa says:

    Had my tubal done last January and they removed 5cm on each side . Can I still have a reversal ?

    1. Dr. Monteith says:

      If you had 5 cm removed then you dont have enough tube left to reverse. Sometimes mistakes are made in the notes or the interpretation of the notes. It would be best if you sent us your tubal ligation operative note and the pathology note for review. We can let you know if you are a candidate.

    Hi Dr. Monteith, I will be sending my records very soon as I pick them up from my dr tomm. I am trying to push forward w reversal surgery and heard your the best. Upon speaking with the nurse she advised me that approx. 2/3 of tube on each side were damaged during ligation leaving 1/3 on each side. Is this possible to reverse?

    1. Dr. Monteith says:

      The nurse provides you with my interpretation ….so whatever she said is correct. We never know with 100% certainty until we actually look at your tubes. We should be able to reverse your tubes. If you would like more certainty then you should consider our screening laparoscopy option.

  4. Christa says:

    Hi Dr I had my tubalagation surgery. However I want to do the reversal surgery. Is it possible to get pregnant they removed 3 centimeters of my tubes however the operative report says only one centimeter was removed.

    1. Dr. Monteith says:

      We should be able to help you. We can reverse most tubal ligation procedures.

      We charge $6400 total plus $125 to schedule and we are located in Raleigh, North Carolina. Patients pay in full and out-of-pocket at the time of scheduling. All you have to pay for in addition to the surgical fee is the cost of travel, hotel, and food.

      On average the chance of pregnancy after tubal ligation reversal is about 60% if you are under age 42.

      We do have a prepayment tubal reversal plan that allows you to save towards your reversal over a 3 year period.

      Although $6,400 seems expensive…the alternative treatment in-vitro fertilization (IVF) average $12,000 to $14,000 and is about 40% successful!

      The main advantage to tubal reversal is that every month you have a chance and you can become pregnant more than once.
