What is the risk of ectopic pregnancy with IVF?
It is still possible to have an ectopic when having IVF. The incidence of ectopic with IVF sits at about 10% in the UK (or thereabouts) depending on the clinic. This figure differs depending upon the country you look at. This figure is higher than the incidence for the average population which is 2% in the UK and as high as 10% in the Caribbean. But it is no higher than the statistic given for the likelihood of a second ectopic after a first, which averages also at about 10% in the UK. (Alhough this figure too can be higher in some countries and possibly lower in others.) A fertilised egg which has reached the Zygote stage, which means the cells have begun to divide, is replaced in the uterus with IVF at anything from 1-2 days after fertilisation, to 4-5 days when it has developed many more cells and is called a blastocyst. It spends several days floating around before implantation and it is possible to float into the tubes or the stump of tubes or the interstitial area of the uterus.
