Well, of course, Changelings can make complicated contracts or try to use rare Goblin Fruits and Tokens... but since there's no such thing in the core book (and, IIRC, only passing mentions in supplements), it's completely up to the ST whether a Changeling will ever be able to have biological children.
For some, that could be a big game changer. Not all. But some. Just look how many couples IRL are struggling just to have one child that's genetically theirs.
