IVF embryos are more likely than naturally conceived embryos to split into identical twins. A fertility doctor can transfer just one embryo—in hopes of reducing the risk of non-identical twins—but identical twins may still occur, and more frequently than in the general population.

There is about a 1.6% chance of identical twins arising naturally after a single embryo transfer.

Chances of twins with IVF and two embryos Chances of twins with IVF and two embryos. Chances of twins with IVF may access the results to be in a negative sense rather be made it positive allusions that the results may be announced negatively as if the results should be increased as chances are there but not the sure twin pregnancy the expert should recommend in such regard that may accrue the 2010-10-25 Also, about 1% of implanting embryos will split into identical twins. As a result, even when “only” two embryos are transferred, triplet pregnancy can still occur. The risks of low birth weight and prematurity are not to be taken lightly. IVF ups the risk of a twin pregnancy even if only one embryo is transferred, claim scientists. Japanese researchers told a fertility conference in Lyon how the process of IVF encourages embryos to split into identical twins.

“We’ve got twins. I’ve always wanted four children. At worst case, Cameron will be six when the last is born but it could be later — they don’t have an expiration date as such.

Isabella almost was because her embryo split.

The problem is the lateness of the split; there are only about 8 or 9 days when an embryo can safely split (I think by day 8, there is a high risk of an incomplete split, i.e., conjoined twins). If the embryo is selected at day 5 and implanted that day, there is no way for it to split into a true di/di identical pregnancy. They also do not split while frozen.
