Can a 5 day blastocyst split into twins?
There has been an increase in the occurrence of monozygotic twinning secondary to the use of assisted hatching, ICSI, but mostly, the transfer of blastocysts on day 5-6 during IVF. Monozygotic twinning (MZT) occurs when an embryo splits after fertilization, resulting in identical twins.
Are IVF twins really twins?
With IVF treatments, twins have basically become the new norm—46 percent of IVF births are multiples, mostly twins. But now fertility experts want to change that. The new goal: single births, even when using IVF.
Why are twins more common in IVF?
Chances of Having Identical Twins It’s unclear why fertility treatment leads to more identical twins. One theory is that the culture embryos are placed in during IVF increases the risk of identical twinning.

With more eggs being released, women increase their chances of conception as well as chances of having twins. Just like when a woman is older and there is an increased likelihood of two eggs being released, those taking fertilization drugs increase their chances of sperm fertilizing two released eggs.

Babies who share a common sac can be difficult to detect since their heartbeats coalesce pretty much with each other. So, it may not be possible to detect twin pregnancy at the 5th week of pregnancy.
Is a day 6 blastocyst good?
CONCLUSIONS: Transfer of single euploid embryos whether transferred day 5 or day 6 blastocysts provides a good outcome, although with day 5 blas- tocyst a superior outcome was observed. However, the difference between day 5 and day 6 euploid transfers was neglected if two embryos being transferred.
How likely is twins with IVF?
Statistically, women who undergo IVF have multiple pregnancies (twins, triplets, or higher-order multiples) at a higher rate than women who conceived naturally: According to statistics published in 2013, around 40% of all IVF pregnancies in the US resulted in multiple births.
