Shorty Mac and Sickle Cell Anemia

I'm not sure which section to post this in, but since he's a straight pornstar...

I've read several posts claiming that Shorty Mac's mega-girth is a side-effect of the blood disease sickle cell anemia. Has this ever been officially verified? Knowing that a freakish girth like that is the result of a disease would help put things in perspective. The only other pornstar that comes close to his thickness is Shane Diesel but his cock looks sort of half-soft and floppy while Shorty's looks totally hard and compact. It just seems damn near physically impossible.
