Hi! So I’m an (aspiring) author and I’ve encountered a moral hypothetical in my writing that I’m not sure how to solve. Let’s say that one member in a (married) couple is infertile; the couple would like to have children but are actually grateful for this infertility because the same member who is infertile also has a serious genetic disorder that would inevitably be passed on to their children.
Now let’s say that the couple finds out about a miracle fertility pill which would allow them to have children; however, they still want to avoid pregnancy because of the genetic disorder. My question is, is the couple required to take this pill (and presumably practice NFP), or can they choose to remain infertile? Would that render them not open to life?
