@BuzzBrain. Joe Swanson from the animated sitcom Family Guy is also paralyzed from the waist down. He fathered a child after that happened.
@Aragorn. I believe i've mentioned this before: Technically they are still married, but the show has not made this clear. Baelish said to Sansa, when he told her he wanted to marry her to Ramsay, that the marriage was not valid because it was not 'consummated'. Also, dialogue in 'Winterfell' and 'the Long Night' suggests they do not consider themselves married. But, according to both the TV- and the book Wiki, the marriage has to be officially annulled by the hierarchy of the Faith. (As was the case with Rhaegar and Elia's marriage, but on what grounds that marriage was annulled is not mentioned in Sam's discovery).
