Mr. Grave wrote: Doktor made it clear that Raiden could save George's lower half, therefore he can have kids in the future. As for the rest of the cyborgs, I am not so sure, but they all seem like middle-aged, adult people. So it's likely that they had a family before transforming into cyborgs. However, I wonder if Raiden, who wasn't in need for synthetic parts, is still able to reproduce.

Considering that all but his spinal cord and his skill from the upper jaw up are completely artificial, I doubt it.
