This is just proof of concept:
set foldtext=MyFoldText()
function MyFoldText()
let parcnt = 0
execute v:foldstart . "," . v:foldend . "g/^$/let parcnt += 1"
return parcnt . " paragraphs"
endfunction
You might want to return something like
substitute(foldtext, ":", ", " . parcnt . " paragraphs:", "")
(untested).
