I can see the first attempt being immoral as we did not know how the first kids born using that method would turn out. In certain circumstances like using an IVF on older women in their menopause you could also qualify it as immoral due to higher risks to the kids. But unless you have certain religious beliefs where you cannot allow any human interference in the process, i do not see where you see the immorality of the procedure.
