lets not use blunders of scientists to excuse blunders of religious scholars. lets focus on religious scholars here.
I am not criticizing people who had no good means, I am criticizing people who did not put an effort into finding the knowledge or who had knowledge available but did not really put any effort towards it.
More than that I am criticizing people who should have said that they did not know enough about it to make a ruling but its better to be careful and avoid it, instead they went very vocally against it. so it was not they they did not have access to knowledge, they simply did not put enough effort to learn and then make a claim, they just spoke up against it as some sort of authorities, rather than admit that they did not know enough to make a call at that point in time.
before we go any further, I want you to read up a little bit on when IVF was in experimental stages, when it was tested, when it was available, what the initial reaction was by many scholars and how long it took for them to say its okay.
what is your definition of fertility issues. for someone who has no need for it, it does not make sense but the question was whether it would be okay from a religion POV. My view is that from a religious POV, if its allowed its allowed.
