What happens when two embryos are transferred?
Transferring two embryos, when one embryo is poorer quality than the other, may lead to both embryos failing.
2 Embryo Transfer is Best because There has been a big push in the country to transfer only one embryo, mainly to avoid the risks of twins. So, if a patient has four embryos, the recommendation would be to transfer one at a time, until all four embryos would be transferred; as opposed to doing two transfers of two each.
For many patients, they will take on all of this risk if it raises their chance of having a child.

What happens when two embryos are transferred?
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. Double embryo transfers should be limited to patients with repeated implantation failure or repeated pregnancy loss. Yet, when two embryos are transferred, women can be reassured that the quality of the second embryo does not seem to affect the pregnancy rate or the risk of twin pregnancy. It is very tempting for couples to want to have two embryos transferred during an IVF cycle, as it is only natural to assume that doing so increases the odds of achieving that much-wanted pregnancy. In fact, it only increases the chance of pregnancy by approximately 3-5%, compared to transferring a single embryo.

Does transferring two embryos increase chance of pregnancy?
For most women having IVF, transferring one embryo is just as successful as transferring multiple embryos and your chance of having a multiple pregnancy is much lower. Bear in mind that sometimes the highest quality embryo is selected for eSET, which can have a slight impact on birth rates.
Should I transfer 2 embryos?
Many patients undergoing a day 3 embryo transfer still have very good pregnancy success rates but may end up transferring more than one embryo. If a patient is able to proceed with a day 5 transfer, it may be recommended to transfer only one embryo to reduce the high likelihood of a multiple pregnancy.

Can 2 embryos implant at different times?
Yes. However for this to occur, a second egg must be released and also be fertilized within the same cycle before which a hormone triggered by the implanting will be released to void further impregnation. The window of conception can be as wide as 24 days. In rare cases, two eggs can be fertilized at different times during two or more acts of sexual intercourse, resulting in fraternal twins with two different fathers, called bipaternization. Monozygotic, or identical twins, occur when one fertilized egg splits into two separate embryos.
