Causes Of An Ectopic Pregnancy

Unsuccessful Tubal Ligation Or Reversal

Unsuccessful tubal ligation or reversal may also cause an ectopic pregnancy. As always, tubal ligations are not completely successful in preventing pregnancy and can sometimes be reversed. When unsuccessful, the chance of ectopic pregnancy greatly increases. The fallopian tubes are likely to have some scar tissue from the surgical procedure itself, which is not good for healthy implantation. The fertilized egg may implant in the fallopian tube rather than in the uterus. Unsuccessful ligations or reversals may also leave too little room for a fertilized egg to get to the uterus. The reversal process may contribute additional scar tissue formation to whatever may already have been present.
