The fimbria is the most distal part of the fallopian tube. It has a wider structure than the rest of the tube with fringe shaped ends or small fingers that embrace the ovary. Its function is to collect the egg, when it leaves the ovary, and channel it into the fallopian tube.
Tubal ligation by fimbria removal is a common method used for sterilization of women who do not want to have any more children. However, if a woman regrets it and wants to become fertile again, reversing it will not be easy. If the length of the tube is sufficient, the surgeon can perform a reconstruction with the fallopian tube.
Women who have this type of reconstruction have a low success of about 25%. Therefore, patients who are in this situation will be encouraged to undergo IVF treatment to increase their chances of success.
