No one knows for sure why embryos split, but it is known that rates of identical twins are slightly increased by assisted reproductive treatment.
Twins can be either monozygotic ('identical'), meaning that they develop from one zygote, which splits and forms two embryos, or dizygotic ('non-identical' or 'fraternal'), meaning that each twin develops from a separate egg and each egg is fertilized by its own sperm cell.

Being pregnant with twins is a great success and this occurs when more than one embryo is placed into the women. Fraternal triplets are more common than identical or monozygotic triplets. Vanishing twin syndrome happens during twin pregnancies when a woman is carrying twins and then suddenly is only carrying a singleton.

Next in order of most to least common are fraternal girls, fraternal boys, identical . Evidence gathered from time-lapse recordings of the formation of early embryos (blastocysts) in the laboratory has revealed why embryos created via IVF and undergoing extended culture are more likely to develop into twins than those created via natural conception. In vitro fertilization (IVF) is an assisted reproductive technique in which a woman is given hormone medication to stimulate ovarian production.
When a mother carries multiple babies, this applies more pressure and strain on her body.
Why Are Identical Twins More Common with Fertility Treatment Doctors have many theories, but don't really know why assisted reproduction makes it more likely for an embryo to split in two.

This is another risk that comes with IVF twins.
This fertilised egg is called a zygote. There is no logical explanation for why it . All these are called monozygotic twins. The cleavage stage is after three or four days from fertilization, and the blastocyst stage is a week after fertilization when the embryos have reached optimal growth. Identical Twins are formed when one zygote, created with one egg and one sperm, is divided into two. .
