After IVF the incidence of MZT is high, with young oocyte age, year of treatment, and extended culture (or embryo stage at transfer) conferring greatest risk. Regarding MZT type, assisted reproductive technology (ART) procedures may influence the timing of embryonic splitting (i.e., division in earl …

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. There has been mounting pressure to cut the IVF twin rate because of a raised health risk to mothers and babies. A single embryo transfer may still result in twins because of embryo “splitting”. There is about a 1.6% chance of identical twins arising naturally after a single embryo transfer.

Ivf embryo split twins

Of 137 viable twins at the 7-week ultrasound, 109 were delivered as twins. With the only embryo, then 1 egg divides into create 2 zygotes. All these are called monozygotic twins. About the flip side, dizygotic twins really are a consequence of 2 eggs that are separated. This primarily takes place when a couple of embryos are moved into the individual’s uterus throughout the IVF therapy. However, it is possible to increase chances of twins with IVF even with one embryo, where one egg can split to form two zygotes.

At what stage does an embryo split into twins? Zygotic splitting occurs between days two and six when the zygote divides, usually into two, and each zygote then goes on to develop into an embryo, leading to identical twins (or triplets if it divides into three). These are known as “monozygotic” twins (or triplets). My identical girls are from a FET, day 5 blastocycst, no ICSI. I've heard generally that identical twins are more common in IVF than unassisted pregnancies, but never saw any numbers. The ultrasound tech at the fertility clinic said she sees a couple of embryo splits per year, but they are pretty rare.

Dianna Payne, a visiting research fellow at the Mio Fertility Clinic, Yonago, Japan, told the 23rd annual meeting of the European Society of Human Reproduction and Embryology today (Monday 2 July) that about three pairs of twins per thousand deliveries occurred as a result of natural conception, but many more were born after IVF, even when only one embryo had been transferred to the mother (approximately 21 pairs per thousand deliveries). Blastocysts can split more easily than younger embryos, especially good-quality ones. So even a single blastocyst transfer can lead to twins (though it’s not common).
