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.

    I had tubal ligation 8 years ago. I am regretting this decision, since I was young when I decided to get my tubal ligation (23). I am now 32 and would like to be able to conceive one more time. My tubed were cut 2.5 cm and burned at the end. Is it possible to have a reversal and be successful? Please advise. I would like to know what my chances are of conceiving. Thanks in advance

      At the age of 32 you should have good chances for becoming pregnant after tubal reversal. Your chances should be around 70%. We will email you more information. Please give us a call at (919)968-4656 for more information about tubal reversal.
