Can embryo splitting be done on humans?

Embryo splitting is a common science technique for creating duplicate lab animals for research. As such, under the right conditions, there's no reason that it couldn't be done with human embryos as well.

Of course, splitting the human embryo would have to be done externally in glass wear, in vitro. And then transferred to the womb. Embryo splitting is usually done just shortly after fertilization, maybe no more than two or three days post fertilization in humans. There are a number of techniques for splitting a 2 or 4 cell blastula (early embryo).

Splitting the embryo results in identical twins, though the two twins are slightly smaller than the offspring that would have resulted from the intact egg.
