I don't.
Then why did you even bring up the idea that the use of human embryos outside of the womb could be 'immoral' instead of asking about something like the morality of possessing antibiotics?
And of course your statement implicitly suggests that if Science (in your case case medical science) can do something of course it must be moral.
Even a little bit of thought shows that this is not the case. There are all sorts of things which technology has made possible which are not pursued as preferred courses of action.
