Donation and Surrogacy Programme

If scientists and doctors can do in vitro fertilization with an egg and a sperm, why can’t they do it with two ***** or two eggs? Why can’t they take the nucleus out of the egg of one woman, and then put it directly into another egg from another woman? Wouldn’t it have the same effect as injecting a ***** into an egg? What about removing the nucleus from a donor egg, then replacing it with the nucleus of a ***** from one man, and then fertilizing the resulting egg with the ***** of another man?

Would this work? What factors would make this impossible? Is it possible and it just hasen’t been done yet? Has it been done yet, and I just haven’t heard about it?

I want educated answers please. Thank you.
It can be implied that the egg made with the two ***** would be placed in a surrogate mother.
I understand that one of the ***** cells would have to be an X *** chromosome.
Let me remind you one more time:

EDUCATED ANSWERS!

And please read the whole question, I am very aware of what a uterus is and what in vitro means. I am also sure that I know what egg and ***** are and which gender has which.
