My DH asked me a question yesterday that i couldnt answer and told him i would ask the multiple mums on here.
our friends are going through IVF and quite rightly, Dh commented that this would increase their chance of twins as two embyros have just been implanted. But then he asked whether they have just as an increased risk of identical twins and i dont know?
If (in laymans terms) an egg divides to create identical twins, would this still occur for IVF? I know that naturally the fertilised egg would travel through the fallopian tube and could divide and then implant to get identical twins. Would their be sufficient time for this to happen in IVF? Could they still divide before implantation if they have been put back in as a single blastocyst?
i hope that makes sense as i was fascinated by the question and hope MN can answer it.
