There's no source which says as much.

Off the top of my head, unless you count hangar bar at Disney and the definitely non-canon LEGO Indiana Jones: Escape from the Kingdom of the Crystal Skull!, there are no stories after Crystal Skull yet and, at least before Disney bought Lucasfilm, authors expanding on Marion and Colin Williams was not allowed (presumably to avoid conflicting with whatever Indy 5 might have to say).

As for that fertility temple thing, it's the first hit on the Fan Fiction wiki and doesn't have a page here. ;)
