Can ectopic pregnancy by prevented?
Unfortunately, ectopic pregnancy cannot be prevented. Complete tubal occlusion /resection before starting IVF treatment was advocated by the pioneers of IVF, Mr Steptoe and Professor Edwards, following the first IVF pregnancy, which was ectopic. Although this practice may have helped to reduce the incidence of ectopic pregnancy, it is no longer performed. In addition, it will not prevent an interstitial pregnancy, an ectopic pregnancy which implants in the inner part of the tube, which lies within the muscle of the womb.
Ectopic pregnancy after excision of both fallopian tubes is very rare, the mechanism is not fully understood The site of the ectopic pregnancy in these cases were reported as in the tubal stump in about half the cases and the remainder were in the abdominal cavity, uterine horn, ovary and retroperitoneal.
it has also been reported that the lowest risk of ectopic pregnancy was associated with the transfer of a single frozen blastocyst (Human Reproduction 2015).
