Reversal of Tubal Ligation after Divorce
If you have had your tubes tied (tubal ligation) and are now divorced or remarried, you may have changed your mind and want to have more kids.
Reversal of female sterilization can be quite successful and it is estimated that 10-20% of women regret tubal ligation and wish to have it reversed.
The Biology of Pregnancy
For a pregnancy to occur naturally, sperm must enter the fallopian tube through the uterus by way of the vagina and cervix (opening to the uterus or womb). The oocyte (egg) is released from the ovary and is picked up from the other end of the tube (ovarian or fimbrial end). When the fallopian tubes are blocked, sperm and eggs are kept apart and fertilization is prevented.
The fallopian tube is a narrow muscular tube arising from the upper corners of the uterus and ending just next to the ovary. The inner tubal lining is rich in cilia, microscopic hair-like projections that beat in waves that move a fertilized egg (embryo) towards the uterus. The fallopian tube is normally about 10-12 cm (4–5 inches) long.
Factors in Successful Reversal
In general, at least 5 cm or greater in tubal length is needed for the best chance at success after tubal reversal. There are a variety of ways that the original ligation could be done. Reversal has an even better chance of success if the tubal ligation was performed with clips or rings. The surgery is less successful if the tubes were cut (burned) using an electrocautery instrument or if other pelvic disease such as scaring or endometriosis is present.
Tubal reversal works best for women in good health, in their late thirties or younger, who have a fertile partner. The results are best from this surgery if it has been 10 years or less since the original tubal surgery, and only small sections of the tubes have been damaged by the previous surgery.
