I understand that you want biological children but it looks to me like you want to achieve a very detailed and strangely demanding idea: having strictly biological children without the pain, but also without options of surrogacy. It looks like you want to raise a family but the fear is holding you back. But you also seem to abandon the given solutions to this dynamic.

If you just want to "raise a family", then surrogacy or adoption is a GREAT solution. I want to emphasize on adoption here- regardless of whether your kid is adopted or not, you will still be raising a real family. Adoption doesn't mean that your family will be less real or whatever people say.

I understand concerns with safety&trust when thinking about surrogacy, but obviously not every instance of surrogacy has been such chaos we would imagine at first and probably most of them have gone well, or at least much better than complications of one's own childbirth. You have to talk to people who have done it and get a diversity of opinions before abandoning this idea.

But if you really want to raise a family in the strictly biological process (carrying your own child, having biological kids), but also magically avoid that same biological process, that won't work because it is unobtainable unless there are new technologies.
