Well it seems to me, and i am not very knowledgeable on the subject, far from it.
They freeze sperm, and that in itself has all the necessary functions to become a person once thawed out and placed into the woman.
So although they are super tiny people, which at one stage were frozen for up to many years, all the functions and brain power come to life.
I probably have no idea what I'm talking about, but then again i am no scientist either.
