Ctrl Alt Del: there’s non-commission of a mitzva chiyuvis due to oneis [“act-of-god” like situation], which is unfortunate, but not an “aveira”. There is also non-commission of a mitzva chiyuvis due to not caring enough to really try. This is incorrect. Even worse than that, would be to try to disguise not caring about a mitzva as caring about the fact that wives are much more than their reproductive organs. While this is an undeniable truth, as religous jews, the first and primary reason why we marry is to fulfill the first and primary mitzva in the torah.
Obviously, there is an entirely different discussion to be had about whether this individual girl has significant fertility issues. I have no clue. But to say that such concerns are somehow reducing a woman to her reproductive organs, seems directly, repeat, directly, opposite to what God wrote in our holy infallible Torah.
