The fertilized egg is transferred to the womb of the Silver Sister who will bear, birth and raise the child just like Selforge citizens do, as if she was her true mother from the very beginning. As for their biological mother, I suggest reading the new last paragraph of the "Selforge Metaradise" section, that your question directly inspired ;)

Indeed ! And here again, thanks for inspiring the update I just posted ^ ^

All Selforge Technologies are derived from Lawrence, and his capabilities are increasing endlessly, both externally via the introduction of new data, and internally via reeginnering of available ones. So while each technology is limited to the functions it was created for, all of them can be updated and upgraded indefinitely within their respective field.

Thank you ^ ^ I did think it was very thoughtful and generous of him as well.

Selforge City is historically based on close personal bonds with its founding master, and it translates in its immigration policy from the very beginning (see the first section of "Base of Operations"). So these bonds would have to be forged beforehand, ensuring along the way they are suitable candidates and would feel at home in his world.
