[Star Wars] Were the clone Troopers sterile?

And if not... they were stationed across the galaxy.  Is Fett's DNA the widest spread in human history?

We don't know if they're sterile. There's probably a large stigma against being with a clone after they were forced out the military.

We only know of one Fett clone that had a family, a Twi'lek woman who had had two children from a previous relationship with a human, so we don't know if the clones are sterile or impotent or "fully functional." The Kaminoans never state whether they alter anything besides aging and making them more likely to follow orders, though.
